new Chen’s laboratory in Weizmann’s Brain Sciences Department focuses on the molecular and behavioral aspects of the response to stress. In previous studies, Chen’s team examined how stress during pregnancy affects mouse offspring when they reach maturity. In the current research, the scientists, led by Dr. Aron Kos, studied how trauma experienced shortly after birth affects mouse pups later in life. To advance the understanding of this topic, the researchers pulled together the strengths of Chen’s lab: its expertise in exploring the brain’s molecular processes at the highest possible resolution, using genetic sequencing on the level of individual cells; the ability to use cameras to track dozens of behavioral variables in a rich social environment intended to recreate natural living conditions; and the ability to process the massive quantities of data generated in this environment, using machine learning and artificial intelligence tools.Weizmann Wonder Wander - News, Features and Discoveries from the Weizmann Institute of Science, 1d ago
new Diagnosis is another area where AI is playing a key role. “Based on morphological markers of the patient, it tells us exactly what kind of a retinopathy the patient suffers from. It also provides us with the grading of DR,”says Pillai. “For instance, proliferative DR would be classified as a vision-threatening one and require urgent treatment as against a mild DR. Also, deep learning or machine learning can pick up a lot of things that ordinary eyes cannot pick up, especially when there is large data.”As of now, Pillai and his team are trying to explore the possibilities of predicting heart attacks and strokes using the retina.theweek.in, 1d ago
new Owing to the remarkable properties of the somatosensory system, human skin compactly perceives myriad forms of physical stimuli with high precision. Machines, conversely, are often equipped with sensory suites constituted of dozens of unique sensors, each made for detecting limited stimuli. Emerging high degree-of-freedom human-robot interfaces and soft robot applications are delimited by the lack of simple, cohesive, and information-dense sensing technologies. Stepping toward biological levels of proprioception, we present a sensing technology capable of decoding omnidirectional bending, compression, stretch, binary changes in temperature, and combinations thereof. This multi-modal deformation and temperature sensor harnesses chromaticity and intensity of light as it travels through patterned elastomer doped with functional dyes. Deformations and temperature shifts augment the light chromaticity and intensity, resulting in a one-to-one mapping between stimulus modes that are sequentially combined and the sensor output. We study the working principle of the sensor via a comprehensive opto-thermo-mechanical assay, and find that the information density provided by a single sensing element permits deciphering rich and diverse human-robot and robot-environmental interactions.interestingengineering.com, 1d ago
new A new study from Mass Eye and Ear investigators shows that individuals who report tinnitus, which present as a ringing in the ears in more than one out of ten adults worldwide, are experiencing auditory nerve loss that is not picked up by conventional hearing tests. This work is part of a P50 grant awarded by the National Institutes of Health (NIH) to Mass Eye and Ear researchers within the Eaton-Peabody Laboratories (EPL) for their work on cochlear synaptopathy, which is commonly referred to as "hidden hearing loss." The results from this study provide a better understanding on the origins of tinnitus and are published November 30th in Scientific Reports.ScienceDaily, 1d ago
new In the fifth book I’ve selected, Waller’s Against Moral Responsibility, one of the sources he appeals to in support of his scepticism about moral responsibility is data coming from neuroscience. This reflects a wider trend in philosophy, which is to be better informed and more deeply integrated with advances in empirical science and to use these resources to help us understand philosophical problems. To a certain extent, this approach cuts in the opposite direction from Williams, who employs a more humanistic understanding of philosophy, as informed by history and literature. However, neuroscience is very influential in the philosophy of free will right now, as are certain kinds of psychological experiments that aim to debunk our confidence that we are agents making conscious choices and in control of ourselves. The gist of Waller’s book is that we aren’t really responsible at all, because the kind of control that we think of as essential to responsibility is illusory. His principal argument in support of this conclusion is that we are vulnerable to luck, but another layer of his scepticism relies on neuroscience data — and, as you say, Libet is really the major figure here. While we may have a conception of ourselves as conscious agents making choices, the empirical data that Libet has provided claims to show that it is not the conscious self that decides but prior events in the brain. It can be shown experimentally that the brain has already settled how we will act several hundred milliseconds prior to our awareness of making any conscious choice. This supports a seemingly sceptical position about the role of conscious choice, on which responsibility seems to rest, since how we will act is already settled prior to the occurrence of conscious choice itself. The conscious agent, it seems, is not really in charge of conduct.Five Books, 2d ago

new Dr. Durrance has an interdisciplinary research and education program in long-term human space exploration. The hazards associated with long-term exposure to the space environment, such as radiation damage and the loss of bone mass, are not sufficiently understood to determine whether they pose acceptable risks or not. Research focused on these hazards is critical to sustained human presence outside the protective environment of the Earth ’s atmosphere and magnetosphere. This program uses the Space Life Sciences Laboratory (SLS Lab) at Kennedy Space Center (KSC); as well as labs at Florida Tech.Lunar dust physics: Enabling technologies must be developed, including systems to mitigate the damaging effects of dust contamination; technologies that use the local planetary resources to produce consumables such as oxygen, water and rocket propellant; food production systems; innovative range technologies and many more. We are currently studying the induction charging characteristics of lunar dust.Bone Loss: The objectives of the bone project are (1) to provide a dynamic model of the structure and function of bone in response to loading with sufficient precision to predict the effect of any arbitrary loading history and (2) to develop and refine new countermeasures against bone loss.Radiation damage: Solar and galactic radiation is a major hazard to space crews during long-duration flights and planetary bases beyond the Earth ’s magnetic field. Intense solar flares can induce acute radiation sickness, galactic cosmic rays can kill brain cells that the body cannot replace, and all forms of radiation can induce cancer. The only known safety measure is shielding to prevent the high-speed particles from reaching the crew.Dr. Durrance is has an interdisciplinary research and education program in astrobiology addressing three fundamental questions: How does life begin and evolve? Does life exist elsewhere in the Universe? What is the future of life on Earth and beyond? Research addressing these questions is highly interdisciplinary involving fields such as physics, biology, chemistry, geology, and planetary science.Extrasolar Planets: Most of the newly discovered planets have been found using indirect techniques, where the planet ’s effect on light emitted from the parent star is detected, not the light emitted by the planet itself. The most likely technique for detecting life on these planets is a detailed analysis of their spectra; therefore, we are developing a system that may be able to detect IR emissions from exoplanets using large, ground-based telescopes along with Very Long Baseline Interferometry (VLBI) techniques developed for radio astronomy.Amyloid Fiber Formation: We are pursuing research that may shed light on a fundamental question regarding the origin of life: how did the transition from non-living to living matter occur? We are investigating the spontaneous formation of long linear fibers from a weak solution of proteins using dielectric spectroscopy. This phenomenon may be important in neurodegenerative diseases and it may help to understand the emergence of ordered biological structures that are far from thermodynamic equilibrium.Dr. Durrance Director of the Sub-Orbital Research and Training Center that utilizes flights of high performance F-104 jets from the Shuttle Landing Facility (SLF) at KSC. In addition to the testing of prototype spaceflight hardware for NASA and commercial companies, we are developing an imaging system designed specifically for imaging Earth ’s coastal regions. The coastal zone is not only the most significant ocean area in terms of productivity, economics, recreation, and natural resources but it is also the most difficult to image.fit.edu, 2d ago
new One example of this is autism, once thought to be something that almost exclusively affected males. In fact, under something called the brain organization theory, it was thought that sex hormones present during fetal development permanently “masculinized” boys’ brains in ways that made them, among other things, more likely to have autism. Recently, there’s been a rethink and a huge increase in our understanding of how autism presents differently in women and girls, leading to many more diagnoses.IFLScience, 2d ago
new The other research is from Mattia Veronese, PhD, a scientist from King’s College in London and associate professor at the University of Padua in Italy, who studied human PET imaging data of participants of the Alzheimer’s Disease Neuroimaging Initiative (ADNI) to look for brain network changes and disease progression using the network neuroscience approach developed by Sporns. Veronese is also a co-author on the Alzheimer’s & Dementia journal article. “Those two pieces of work led our team to develop tools that would extract additional meaning from images of MODEL-AD mouse models, with the goal of not only providing similar whole brain metrics observed in the previous clinical studies, but to also dive deeper and possibly understand how subnetworks within the brain of these models might shed light on the mechanisms of the underlying biology,” Territo said. Chumin helped develop the tools and resources from the network neuroscience approach of human clinical research to preclinical animal models of MODEL-AD. The investigators analyzed the brain as a whole and also looked at subnetworks within the brain to see how those areas communicate and interact as the disease progresses. “Using this approach, the research team’s analysis of metabolism changes in animal models confirmed previous clinical findings of disease progression in patients with Alzheimer’s disease,” Territo said. The animal models showed age-related changes in glucose uptake as well as differences between males and females—similar to findings from Alzheimer’s disease human data. Territo said MODEL-AD plans to use these network neuroscience tools in their investigations of other preclinical data, including models of late-onset Alzheimer’s disease, potential therapeutics for the disease and multi-modal analyses that combine neuroimaging data from PET and MRI.

According to the complaint, NewsGuard uses software to tag targeted sites with warning labels that describe the content as “disinformation” or “false content.” In the case of Consortium News, its site was labeled as an “anti-U.S.” media organization, even though NewsGuard only took issue with six of its more than 20,000 articles and none of its videos. According to Consortium News:“The complaint seeks a permanent injunction declaring the joint program unconstitutional; barring the government and NewsGuard from continuing such practices and more than $13 million in damages for defamation and civil rights violations.”The U.S. government has also been caught bankrolling the now discredited Global Disinformation Index (GDI), which selectively targeted conservative and non-liberal media. According to the Washington Examiner, the GDI sent blacklists to advertising companies “with the intent of defunding and shutting down websites peddling alleged ‘disinformation.’”NewsGuard’s Task Is to Silence Alternative MediaThe CIA’s Mockingbird enterprise may have been officially cancelled in 1976, but that doesn’t mean its control over the media ended. If the last three years have shown us anything, it’s that all of mainstream media are now completely controlled.If you want any variation of opinion from the prevailing narrative, you have to seek out independent news sources, and these sources are what NewsGuard is trying to destroy. Caitlin Johnstone addressed this in a January 2019 article:“A report seeded throughout the mainstream media by anonymous intelligence officials back in September claimed that US government workers in Cuba had suffered concussion-like brain damage after hearing strange noises in homes and hotels with the most likely culprit being ‘sophisticated microwaves or another type of electromagnetic weapon’ from Russia.A recording of one such highly sophisticated attack was analyzed by scientists and turned out to be the mating call of the male indies short-tailed cricket … The actual story, when stripped of hyperventilating Russia panic, is that some government workers heard some crickets in Cuba …These are just the latest in a long, ongoing pattern of terrible mass media debacles as reporters eager to demonstrate their unquestioning fealty to the US-centralized empire fall all over themselves to report any story that makes Russia look bad without practicing due diligence.The only voices who have been questioning the establishment Russia narrative … have been those which the mass media refuses to platform. Alternative media outlets are the only major platforms for dissent from the authorized narratives of the plutocrat-owned political/media class.Imagine, then, how disastrous it would be if these last strongholds of skepticism and holding power to account were removed from the media landscape. Well, that’s exactly what a shady organization called NewsGuard is trying to do …A new report by journalist Whitney Webb for MintPress News details how NewsGuard is working to hide and demonetize alternative media outlets like MintPress …”As Johnstone points out, NewsGuard is “led by some of the most virulently pro-imperialist individuals in America,” and that “its agenda to shore up narrative control for the ruling power establishment is clear.”NewsGuard Linked to Anti-American Council on Foreign RelationsIndeed, one of NewsGuard’s CEOs, Louis Gordon Crovitz, is a member of the Council on Foreign Relations (CFR), a key player behind The Great Reset. The CFR is financed in part by the Gates, Rockefeller, Ford and Carnegie foundations, and has influenced U.S. foreign policy ever since its inception 95 years ago.Almost all U.S. secretaries of defense have been lifetime members, as have most CIA directors. This is of crucial importance, considering the CFR’s goal, from the start, has been to bring about a totalitarian one world government, a New World Order (NWO) with global top-down rule.Since its inception, the CFR’s goal has been to undermine U.S. sovereignty and national independence in order to usher in an all-powerful one-world government.In 1950, the son of one of the CFR’s founders, James Warburg, said to the Senate Foreign Relations Committee: “We shall have world government whether or not you like it — by conquest or consent.”26 Similarly, in 1975 CFR insider Admiral Chester Ward wrote that the goal of the CFR was “submergence of U.S. sovereignty and national independence into an all-powerful one-world government.”According to Ward, the desire to “surrender the sovereignty and independence of the United States is pervasive throughout most of its membership,” and “In the entire CFR lexicon, there is no term of revulsion carrying a meaning so deep as ‘America First.’”With Ward’s last comment in mind, published in 1975, it’s interesting to contemplate who has opposed President Trump’s America First agenda, and why. Many Americans, even if they don’t like or support Trump personally, agree that taking care of America and Americans’ interests first is a rational decision for any leadership, and they’ve been hard-pressed to rationalize how an anti-America First policy can be good for the nation.Well, Ward gives us the answer. Those who oppose “America First” policies do so because they’re working on behalf of a network that seeks to eliminate nationalism. The idea of government waging war on its own citizens seems completely irrational and inexplicable — until you realize that the CFR has controlled U.S. foreign relations for nearly a century, and its primary goal has always been to undermine U.S. sovereignty and abet the creation of a one-world government.NewsGuard’s advisory board is also loaded with neocon think tank members, including Tom Ridge (George W. Bush’s secretary of Homeland Security), Michael Hayden (an intelligence community insider), and Richard Stengel (Obama’s under secretary of state for public diplomacy and pubic affairs and a former editor at Time Magazine).Tellingly, Stengel has publicly stated that he supports the use of domestic propaganda against U.S. citizens. As noted by Johnstone:“Whoever controls the narrative controls the world. Ruling power’s desire to regulate people’s access to information is so desperate that it has become as clumsy and ham-fisted as a teenager pawing at his date in the back seat of a car, and it feels about as enjoyable.They’re barely even concealing their desire to control our minds anymore, so it shouldn’t be too difficult to wake everyone up to their manipulations. We need to use every inch of our ability to communicate with each other before it gets shut down for good.”‘Middleware’ — The Latest Plan to Shut Down Free Speech...Think About It Online, 22d ago
..."Given how revolutionary it is for humanity, imagine a technology like that being released with no prior testing, no deliberative democracy, no oversight, no premarket clearance, very little discussion or even safety testing," she said.Artificial intelligence could make it easier for social media companies to exploit the human brain for profit, Ms. Farahany said. But it can also be used for good.AI-assisted work can reduce burnout and increase worker safety, she said, citing studies by Pennsylvania State University and Microsoft."We're entering into an age of partnership with technology," Ms. Farahany said. "That's threatening for many people, but it doesn't have to undermine human thinking, if we invest in the right way."CMU's Block Center for Technology and Society expects to release a report this week on operationalizing AI across various business sectors.Even the controversial idea of computers building psychological profiles for humans isn't inherently harmful, Ms. Farahany said. Duolingo's AI-powered understanding of human learning helps people learn languages faster. Personalized dieting software could similarly help people lose weight."I don't think addiction is necessarily in and of itself bad," she said.But when the addiction overrides humans' ability to act in their own self-interest, then there's a problem.AI has already infiltrated daily life in ways that can be hard to detect. Ms. Farahany showed statistics that suggest 77 percent of people are using an AI-powered device, but only 33 percent of people are aware they are.One way to overcome the gap in understanding is through education, she said.In Finland, public school children are learning how to discern between content that was manipulated with AI. That awareness could become more important as deepfakes infiltrate political races and pornography.Her strongest example of AI being used for good was in the early detection of seizures. By training computers on epilepsy data, researchers in Israel and Spain can now identify warning signs of a potential seizure before it occurs."This is the kind of insight where we're designing technology for human flourishing and we can imagine a really different world," Ms. Farahany said.Her talk was part of CMU's fall lecture series. Duquesne University is hosting its annual tech ethics convention on Friday, focused on generative AI.Global leaders met in Britain last week to discuss the responsible development of AI. The summit came days after President Joe Biden signed an executive order demanding safety testing from AI developers and assigning federal agencies to oversee the explosive technology.©2023 the Pittsburgh Post-Gazette.

The commercial and industrial energy transition can sometimes seem like a chronological oddity—taking hold 10 years from anywhere. The end zone looks to be a long way off.Truthfully, most industry sources acknowledge the future is now for deep investments in decarbonation technologies on all fronts, from renewables to electrification to microgrids and energy efficiency. While waiting may be counter-productive, the business case also must be immediate and obvious to the customer, as well.The electrical distribution technology sector, Schneider Electric’s Rohan Kelkar said, is the backbone of the C&I energy transformational moves. And even the backbone—from switchboards to motor controls—has to make its fiscal case now.“In the end, like everything else, we will be successful in the journey if it’s cost-effective,” Kelkar, executive vice president of Schneider Electric’s global power products division, said in an interview with Microgrid Knowledge.“This has to make sense,” he noted. “The economics of sustainability and changing the way you do power management has become a local topic.”Local means here and now. Some of the fruits of decarbonization are not as evident in the near term as they will be years down the road, but CFOs and sustainability managers need to calculate the cost-benefit ratio at this moment.SE’s power products unit creates the tools that convert the digital to the operational. A microgrid, for instance, is a body made up of three parts: the controller, which is the brain; the generation assets, which are the physically active components; and the connective tissue such as the circuit breakers, switchgear, and boards which shift digital control to generation output, whether it’s solar, batteries or gen-sets, he added.“We were kind of the sleepy side of the industry, as everybody focuses on the generation side,” Kelkar said.But now a giant has awakened as the future of distributed energy and resiliency of the overall grid increasingly relies on bi-directional flow of energy. Think virtual power plants, microgrids, vehicle to grid, and etc.Electric utilities face an extreme challenge, both commercially and technically, to their one-time and one-way dominance, Kelkar said. Prosumers are gathering power and decentralized or distributed energy resources (DER) are combining forces to create a gathering storm to the old ways.Yet the disturbance in the force must be harnessed and controlled to benefit all parties. That’s where artificial intelligence (AI) and on-site installation of direct current (DC) DERs comes into play.“In a way we have too much data and too little insight. . . Technically, how do you manage it? Operationally how do you manage it?” Kelkar added. “Some grids are not capable of handling it, and that creates challenges and opportunities.”Microgrids are becoming ever more prominent dotted along the energy landscape in the U.S. and around the world. Transparency Market Research, for one, estimates that the microgrid sector is growing about 11 percent annually and may more than triple from 2020 to $206 billion in value by 2031.DC appears to offer the best use-case flow for that scaling up, many industry leaders said at the RE+ event earlier this fall, echoing Kelkar’s thoughts on the subject.DC microgrids can offer several key efficiencies and higher integration of on-location resources such as rooftop solar and battery storage. Many industry experts, including Kelkar, believe it could be the preeminent method of electricity distribution for the future.“Scratching the surface of this frontier are DC microgrids,” he pointed out, while noting that Thomas Edison was pushing direct current as a primary electric transmission method nearly 150 years ago, losing out to Tesla, Westinghouse and alternating current.DC, however, is A-Ok and ideal for on-site power power generation since much of the equipment is already built for direct flow.“To manage and scale that microgrid, the larger number of sources and loads are a complex challenge (best solved) with DC,” Kelkar said.AI’s rise and resulting growth in power load is close to 10-fold over what it was even a decade ago. The data center and cloud sectors require connection and generational capacity beyond what the traditional grid can likely offer, not even taking transportation electrification into account.“Can we design things smartly so they can draw less power?” Kelkar asked. “We’re going into the basic principles of design. Second, when we deploy a product can we dynamically manage the consumption?”There’s good old sleepy energy efficiency again, a “first fuel” for decarbonization that benefits from digital controls, sensors and AI to make sense of all that data.And reducing greenhouse gas emissions is ever more crucial as climate change unleashes its impact with accelerating ferocity.“There’s education and urgency to take action around sustainability and decarbonization,” Kelkar noted. “It is very top of mind for all of these companies. The question is how can we do it and not collapse the grid?”...Microgrid Knowledge, 18d ago
Alterations in the brain associated with autism spectrum disorder (ASD) are thought to arise very early in development, especially during fetal and infant stages (Hazlett et al., Nature, 2017; Willsey et al., Cell, 2013). Analyses of postmortem brain tissue, genomic variations and neuroimaging data have all contributed crucial information to our understanding of human brain development and how it can go awry. However, questions surrounding the earliest periods of brain development in ASD have been difficult to answer in those types of studies. Over the last decade, studies using brain organoids — small self-organizing three-dimensional models of the brain tissue grown in vitro — have been able to recreate at least some of the cellular diversity of the early developing human brain under controlled conditions. Using organoids as an in vitro proxy, researchers can now investigate the differences in molecular and cellular mechanisms that underlie typical and atypical early brain development. In recent noteworthy examples of this approach, two different studies led by SFARI investigators created brain organoids derived from stem cells of people with ASD and neurotypical individuals and identified transcriptional changes that may be associated with ASD during early brain development at the level of single cell types (Jourdon et al., Nat. Neurosci., 2023; Li et al., Nature, 2023).SFARI, 24d ago
In this review, we advocate that integrating sensory ecology into collective behaviour will expand conceptual and methodological approaches and bring new depth and discovery to the field of collective behaviour. We start by describing the current status of the two fields and set forth our case for their further integration. We then introduce the idea of the sensory collective, where different sensory inputs are perceived and shared via signals or cues among members of a group and integrated into an overall collective perception. In doing so, we discuss the potential benefits afforded by the increased sampling range of the collective and discuss the potential costs of group-induced noise. We then consider how the study of collective behaviour may provide new insights and models for understanding the evolution of sensory systems, assessing whether selective pressures are exerted by sensory collectives. Such an approach has yet to be thoroughly investigated in sensory ecology, but is likely to generate new insights into forces shaping the form and functions of visual, olfactory, haptic, thermal, auditory, magnetic, gustatory, and other sensory systems. With this goal in mind, we highlight a few examples of systems in which further study of how collective stimuli might shape the evolution of sensory systems seems likely to be fruitful. Building on this, we offer some examples of how collective stimuli might shape the evolution of sensory systems and discuss neural circuits involved in sensing and collective behaviour. We illustrate this by focusing on examples from diverse taxa and highlighting the promise of shared model systems in furthering this goal. Importantly, combining collective behaviour and sensory ecology requires new methods and theoretical approaches. To this end, we review emerging conceptual and methodological advances, and identify testable hypotheses and potential applications suitable for driving this research forward towards quantifying a ‘sensescape’. We explore what it will take to understand the combined and intersecting sensory perceptions of social individuals and, more critically, how sensory systems scale up to the level of group decision-making and the resulting collective behaviour. We conclude by discussing the applications and significance of sensory collectives for biological conservation, arguing that determining the umwelten of a sensory collective is essential for understanding how animals respond to sensory pollution and anthropogenic change. Given the increasing impact of human populations on animal ecology and population dynamics, we suggest understanding the sensory ecology of collectives will offer important insights into conservation initiatives.eLife, 5d ago

new Thinking across species in the context of slavery in the Caribbean can help to engage the historically embodied reality of being Black in a shared, oppressive world. The talk begins with a summary of my PhD research, which explores how anglophone Caribbean neo-slave narratives rewrite Black humanity and the nonhuman world against controlling anti-Black images. It will examine how this decolonial ecocritical reading has revealed hidden histories of interspecies violence and resistance during slavery in a distinctly Caribbean context. Reflecting on the ways I have sought to deepen and disrupt my own typical methods of engaging with neo-slave narratives, this talk examines how my thesis has evolved into visual and auditory art within my current role as a creative practitioner in residence at ILCS. I will reflect on my process and progress in creating two large-scale visual art pieces and soundscapes as ways of animating my own literary analysis of two Caribbean neo-slave poems. In doing so, I seek to highlight how a multi-sensory experience of Caribbean neo-slave narratives can provide a powerful tool for examining the limitations and possibilities of written literature in re-presenting the intimacies and enigmas of embodied contact with our complicated world. Renée Landell is a Creative Practitioner at ILCS, School of Advanced Study. She has recently finished writing up her PhD thesis which undertakes decolonial ecocritical approaches to Anglophone Caribbean neo-slave narratives. Alongside her research, Renée works as the founding director of Beyond Margins UK, a racial justice and equity movement, and as co-founder of Black in Arts and Humanities, a global online network of Black scholars and practitioners. She is also a writer represented by the leading international literary agency, Andrew Nurnberg Associates, and has appeared on Al Jazeera News, BBC News and CBS (Canada) as a commentator, and more recently in the BBC 2 documentary 'David Harewood on Blackface' as an on-screen historian.School of Advanced Study, 2d ago

new Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, light weight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase modulators are polarization-sensitive, meaning that they affect the phase of light differently depending on its polarization. This can limit their performance and functionality in some applications.There are two main approaches to realizing polarization-independent LC phase modulators. The first approach is to use polarization-independent LC materials, such as polymer-stabilized blue-phase liquid crystals (PS-BPLCs). However, PS-BPLCs require high driving voltages, which can make them impractical for some applications.The second approach is to change the alignment of the LC directors. One way to do this is to use a double-layer LC cell, which consists of two LC cells stacked on top of each other with their LC directors oriented orthogonally. This allows light to be decomposed into two orthogonal components, each of which experiences the same phase modulation. However, double-layer LC cells are complex and difficult to manufacture.Another way to achieve polarization-independent LC phase modulation is to use orthogonal photoalignment. This involves using a special photoalignment layer that creates orthogonal alignment domains in the LC. However, it is difficult to achieve precise alignment using this method.In a new paper published in Light: Advanced Manufacturing, a team of scientists led by Professor Jiangang Lu have developed a new approach to polarization-independent LC phase modulation.Polarization-independent LC phase modulation is based on a light-controlled azimuth angle (LCAA) process. The LCAA process uses the optical rotatory effect of cholesteric liquid crystals (CLC) to create single-layer, multi-microdomain, orthogonally twisted (MMOT) structures.MMOT structures are composed of multiple microdomains with orthogonally aligned LC directors. The LCAA process uses a patterned light beam to control the alignment of the LC directors in each microdomain. This allows the researchers to create MMOT structures with precise alignment.LC phase modulators with a single-layer MMOT structure have the potential to be both polarization-independent and have a large phase depth. This makes them ideal for a wide range of applications, including optical communications, wearable devices, and displays.A light-controlled azimuth angle (LCAA) process can be used to fabricate a multi-microdomain orthogonally twisted (MMOT) device with low polarization dependence, high phase retardation, and a simple structure. The alignment angle between the top and bottom substrates in the LCAA process and the mask grid size of the MMOT structure can be tailored to meet the requirements of different applications.This device has the potential to revolutionize the way we use light in a variety of applications. For example, it could be used to create new types of optical communications systems that are more efficient and reliable. It could also be used to develop new types of wearable devices that can display information in a more clear and concise way.newswise.com, 2d ago
new Major current projects in Dr. Shenker's laboratory focus on processes affecting the recruitment and survival of larval and juvenile fishes. A primary program is the Bonefish Restoration and Conservation Program, where Dr. Shenker works with a team of collaborators to study bonefish prespawning aggregations in the Bahamas. In addition to tracking fish on their spawning migrations, the team examines behavior and biology of fish at prespawning aggregation sites and tracks their final movements to spawning sites. Dr. Shenker leads the efforts to collect and hold fish from the prespawning aggregation to induce spawning in captivity and study the embryonic development and the feeding biology of the leptocephalus larvae. The results of this work are being incorporated into an aquaculture project at Harbor Branch Oceanographic Institution that seeks to develop population restoration tools for the Florida Keys bonefish populations. In addition to the bonefish work, Dr. Shenker's students have helped identify spawning sites of tarpon off the southeastern Florida coast and in the Gulf of Mexico. Continuing with the bonefish theme, his graduate students are working on age and growth of adult bonefish populations in Cuba, and on the sensory biology of larval bonefish.fit.edu, 2d ago
new In brains, online learning (editing weights, not just context window) is part of problem-solving. If I ask a smart human a hard science question, their brain may chug along from time t=0 to t=10 minutes, as they stare into space, and then out comes an answer. After that 10 minutes, their brain is permanently different than it was before (i.e., different weights)—they’ve figured things out about science that they didn’t previously know. Not only that, but the online-learning (weight editing) that they did during time 0<t<5 minutes is absolutely critical for the further processing that happens during time 5<t<10 minutes. This is not how today’s LLMs work—LLMs don’t edit weights in the course of “thinking”. I think this is safety-relevant for a number of reasons, including whether we can expect future AI to get rapidly smarter in an open-ended way without new human-provided training data (related discussion).alignmentforum.org, 2d ago
new Exhibit A is Amara’s law, named for scientist, researcher and former President of the Institute for the Future Roy Amara. He is best known for saying, “We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.” Boy howdy, does that ever apply to digital technologies in general and artificial intelligence specifically. AI may change the world — curing cancer, reversing climate change or taking all our jobs while creating a bunch more new ones — but mostly in the outbound years and decades. In the near term, it creates shadows for us to worry about, plan around and get distracted by even as we experiment and put it to work.In many respects, GenAI represents a victory lap for Moore’s law, based on Intel co-founder Gordon Moore’s formulation about the exponential growth of computational prowess. Originally coined in 1965 around the doubling of transistors on microchips every couple of years, it bumped up against the physical limits of silicon-based technologies. As AI models grow massively in size, from millions to billions and even trillions of parameters, the underlying hardware continues to keep pace even as margins narrow. Chip maker Nvidia, with its combination of advanced graphics processing units (GPUs) and tensor processing units (TPUs) that are optimized for AI tasks, reaches beyond transistor density in pushing the upward limits in the exponential increase in computational power.Not far behind, but perhaps in a supporting role, is Metcalfe’s law. Named for Ethernet inventor Robert Metcalfe, it suggests that the value of a network is proportional to the square of the number of its users. When the campaign for digital government was young, broadband penetration reached 51 percent — giving advocates the opportunity to claim that government could then serve a “digital majority.” As of last year, that number has reached 90 percent. The stakes are high for the remaining 10 percent, often characterized as underserved communities including low-income and racialized populations along with people who have chosen not to engage in a connected world. By extension of Metcalfe’s law, more user interactions contribute to AI’s knowledge, which relies on iterative feedback for fine-tuning and improvement. The absence of marginalized voices is deafening to generative models. They cannot be trained with what isn’t there, increasing the risk of unconscious bias and the skewing of results.GovTech, 2d ago

Prof. Riby began his academic life studying for a PhD at Bristol University in experimental psychology on the topic of attentional control and multi-tasking in ageing. He then moved on to Stirling University to obtain his post-doctoral training in the use of multimodal brain imaging in the investigation of human memory. This early work was influential in driving his interest in the use of mixed methodology (behavioural, neuropsychological and imaging) to explore some of the critical research challenges in the field of gerontology. For instance, a programme of work is using brain imaging techniques (EEG and fMRI) to examine self-generated thought and mind-wandering patterns across the lifespan. The research examines how differences in brain network connectivity in ageing between temporal and prefrontal brain regions predicts positive impacts on behaviour (e.g. creativity; problem-solving; positive aspects of self-reflection). Beyond fundamental science, his intervention work aims to use what we have learnt in the lab to build novel and engaging programmes to encourage the use of untapped brain resources, promoting enhanced mental performance and wellbeing as we grow older. Prof. Riby’s work overall aims to lead theoretical and methodological development of successful and less successful ageing (e.g. diabetes; dementia) with the emphasis that decline is not inevitable. Further interests include the nutritional neurosciences, cognitive neuroscience of mindfulness/meditation and the link between mindful running and psychological wellbeing. More recently, Prof. Riby is conducting a series of behavioural and neuroscience investigations on music's potential to heal the mind.EconoTimes, 19d ago
True, but you can always wriggle out saying that all of that doesn't count as "truly understanding". Yes, LLM's capabilities are impressive, but does drawing SVG changes the fact that somewhere inside the model all of these capabilities are represented by "mere" number relations?Do LLM's "merely" repeat the training data? They do, but do they do it "merely"? There is no answer, unless somebody gives a commonly accepted criterion of "mereness".The core issue with that is of course that since no one has a more or less formal and comprehensive definition of "truly understanding" that everyone agrees with - you can play with words however you like to rationalize whatever prior you had about LLM.Substituting one vaguely defined concept of "truly understanding" with another vaguely defined concept of a "world model" doesn't help much. For example, does "this token is often followed by that token" constitutes a world model? If not - why not? It is really primitive, but who said world model has to be complex and have something to do with 3D space or theory of mind to be a world model? Isn't our manifest image of reality also a shadow on the wall since it lacks "true understanding" of underlying quantum fields or superstrings or whatever in the same way that long list of correlations between tokens is a shadow of our world?The "stochastic parrot" argument has been an armchair philosophizing from the start, so no amount of evidence like that will convince people that take it seriously. Even if LLM-based AGI will take over the world - the last words of such a person gonna be "but that's not true thinking". And I'm not using that as a strawman - there's nothing wrong with a priori reasoning as such, unless you doing it wrong.I think the best response to "stochastic parrot" is asking three questions:1. What is your criterion of "truly understanding"? Answer concretely in a terms of the structure or behavior of the model itself and without circular definitions like "having a world model" which is defined as "conscious experience" and that is defined as "feeling redness of red" etc. Otherwise the whole argument becomes completely orthogonal to any reality at all.2. Why do you think LLM's do not satisfy that criterion and human brain does?3. Why do you think it is relevant to any practical intents and purposes, for example to the question "will it kill you if you turn it on"?...lesswrong.com, 26d ago
The ability to adapt behavior after erroneous actions is one of the key aspects of cognitive control. Error commission typically causes people to slow down their subsequent actions [post-error slowing (PES)]. Recent work has challenged the notion that PES reflects adaptive, controlled processing and instead suggests that it is a side effect of the surprising nature of errors. Indeed, human neuroimaging suggests that the brain networks involved in processing errors overlap with those processing error-unrelated surprise, calling into question whether there is a specific system for error processing in the brain at all. In the current study, we used EEG decoding and a novel behavioral paradigm to test whether there are indeed unique, error-specific processes that contribute to PES beyond domain-general surprise. Across two experiments in male and female humans (N = 76), we found that both errors and error-unrelated surprise were followed by slower responses when response–stimulus intervals were short. Furthermore, the early neural processes following error-specific and domain-general surprise showed significant cross-decoding. However, at longer intervals, which provided additional processing time, only errors were still followed by post-trial slowing. Furthermore, this error-specific PES effect was reflected in sustained neural activity that could be decoded from that associated with domain-general surprise, with the strongest contributions found at lateral frontal, occipital, and sensorimotor scalp sites. These findings suggest that errors and surprise initially share common processes, but that after additional processing time, unique, genuinely error-specific processes take over and contribute to behavioral adaptation.interestingengineering.com, 22d ago

new As a physician-scientist, Perlmutter is internationally recognized for his research on alpha-1 antitrypsin deficiency (ATD), a genetic disorder in which accumulations of a misfolded protein can cause severe liver damage. His work has led to advances in the understanding of how cells dispose of misfolded proteins that cause cellular dysfunction as well as the development of a pipeline of ATD drugs that could eliminate the need for liver transplantation in those with the disorder. Since drugs in this pipeline target and enhance autophagy, a cellular degradation pathway that is critical for the functioning of all cells and declines with age, they also represent exciting candidates for prevention of cognitive decline and other degenerative diseases of aging. Perlmutter and his collaborators recently discovered that a drug currently used for Type 2 diabetes may slow age-dependent degeneration in the nervous system and in the liver.Washington University School of Medicine in St. Louis, 2d ago
Perhaps more exotic is the notion of bio-intelligence in plants. We can’t get our heads around how a plant—lacking a brain or nervous system—could possibly possess awareness and intelligence. Science reduces observed behaviors to provable stimulus/response pairings, but how is our own intelligence fundamentally different than stimulus/response, other than being a complex instantiation? A plant can sense its conditions and react “smartly” to them, in ways honed by the success of the species in the multi-level selection process of evolution. Plants must have figured a lot of things out to successfully operate in this world. They know what they’re about: they have been plugging along for many millions of years. They have awareness, and various means of communication to others. Just because it’s not very human-like does not make it invalid—bringing me back to channeling Jeff Foxworthy.resilience, 3d ago

Since the 3Rs proposal, about 65 years ago, to “reduce, replace, and refine” animal use in the framework of the performance of more humane animal studies (Russell and Burch, 1959), a tremendous effort has been devoted to this goal with rather limited success when it comes to the complexities of studying the brain. Complete replacement of animals may not yet be possible but a reduction based on better management of animals already sacrificed or to be sacrificed is within reach. For unviability of complete replacement take for instance electrophysiological studies.Open Access Government, 6d ago

Progress has been made in partial understanding of the effects of truth. Air inhaled, for example, is identified as and named oxygen, exhaled, carbon dioxide. One is healthy for the body, the other is not. It is known that a farmer who plants guava can never harvest mangoes. That truth must go beyond scientific inventions. Will the advent of Artificial Intelligence (AI) lead mankind to truth? AI is already sending many to the labour market, erasing jobs and positions in companies and service industries. The truth the world is seeking is one that is consistent. It is above crisis, chaos, wars and confusion. It must be one that is unaffected by revolution and time. It must be universal. It is one that is the same in Zurich as it is in Nairobi and the same in Ontario as it is Rio de Janeiro as it is in Accra, Aberdeen or Lagos. It is the same in Seoul or Johannesburg, Miami or Ottawa. It must be the same in Melbourne as it is in Cardiff or Amsterdam. It must not be different from the one in Beijing. It must be valid for all peoples on earth. There must be such truth that withstands time and condition, indeed above all situations and it is timeless. It must be outside the reach of inventions, technologies and theories. It cannot be moved by earthquake or tornadoes. It cannot be anything thought out by human brain. Human beings can only encounter it, recognise it, relate with it because they feel it to the tip of their fingers, but cannot possess it except only its rays beamed on objects or people, personal or impersonal. It is these rays, the splitting of Truth that nature beings, the faithful servants of the Creator, use to weave flowers, make trees, form hills and build mountains, construct rivers, oceans, the lagoon drive air and winds.The Guardian Nigeria News - Nigeria and World News, 18d ago

ANNECY, FRANCE (Nov. 29, 2023) — Salomon unveils a new high-performance race-day running shoe built to deliver the same benefits to everyday runners that elite-level marathoners receive from their shoes. The S/LAB Spectur running shoe, available in May 2024, is a racing shoe that features the same premium materials and technologies used in the shoes of elite runners, but in a design package that benefits middle-of-the-pack runners for their performance objectives. The S/LAB Spectur is not intended to be another training shoe, but a race-day shoe that helps everyday runners perform their best when they want to set a new personal record. The goal of the S/LAB Spectur was to design a running shoe that would help everyday runners be more efficient, similar to what “super shoes” do for elite-level marathoners looking to break world records. When Salomon’s footwear research and development (R&D) team dove deep into the topic in 2021, they discovered that modern “super shoe” designs were benefitting only a small segment of the running population—the most elite 4 percent who run at 14 kilometers per hour or faster (a sub-3-hour marathon pace). They asked themselves how they could deliver a “super shoe” for runners who have different biomechanics than elites. “Pace and biomechanics determine what shoe design will be efficient for runners and, as a consequence, most runners do not have the same functional needs as elite runners,” says Marlene Giandolini, sports and consumer scientist for Salomon. “Today’s super shoes have rocker shapes, carbon plates and narrow heels, and are built for an extremely exclusive group of elite runners. Our studies in the Salomon Sport and Consumer Sciences Lab found that for those who run slower, these ‘super shoe’ designs were, in fact, impairing their efficiency.” With this research in hand, the Salomon footwear design team set out to build a ‘super shoe’ for the majority of runners—people who take their running seriously and set goals, but do not have the same form, biomechanics or body types as elite-level runners. “We believe that elites do not have a monopoly on performance,” Giandolini says. “At Salomon, we believe that performance is a matter of mindset and commitment rather than pace and time. Therefore, our belief is that everyone who trains to beat his or her personal best deserves a ‘super shoe’ that can help them do that.” Whether your goal is a sub four-hour marathon or a 45-minute 10K road race, the S/LAB Spectur delivers race-day exclusivity in an inclusive package for everyday runners. The shoe is designed with all the innovative bells and whistles that “super shoes” for elite athletes offer. It’s lightweight (235 grams / 8.2 ounces) with a specifically engineered carbon plate, dual foam cushioning and an enhanced midsole geometry to improve stability. The difference is in how those features work together to provide the right balance between propulsion and stability. “The question we asked was: How do you make running more efficient? Because that’s what ‘super shoes’ are doing for elite runners who are chasing world records,” says Gatien Airiau, Salomon’s product line manager for road running and an elite distance runner himself. “We’re not trying to change anyone’s running form; the S/LAB Spectur does not change how you run. We’re trying to leverage your biomechanics and your pace to make the fastest shoe possible for you. We didn’t take an elite athlete’s shoe and then take down it to amateur runners. We started from scratch to make a shoe that gives everyday runners the same access to shoe innovations that elites have.” The patented design of the S/LAB Spectur features a more resilient full-length energyFOAM+ midsole, with a top layer made from premium PEBA material, that delivers energy return and unrivalled cushioning. The top foam layer is made from premium PEBA material to deliver This works together with the rocker shape of the shoe to ease propulsion and improve the rocker effect by moving the pivot point backward from where it would be in an elite runner’s shoe. As most everyday runners strike the ground with their heel first, stability and heel-to-toe transition have been major focus points in the S/LAB Spectur design. The carbon Energy Blade plate in the shoe has a unique shape that delivers a balanced transition from heel to toe. The shoe also has a wider heel platform than shoes designed for elite runners to improve stability. Finally, the upper of the S/LAB Spectur features more padding than an elite runner’s racing shoe because most runners spend far more time in their shoes than the fastest runners on the planet, meaning that they are looking for extra comfort. The shoe has an 8 mm drop. “We have fast shoes for the elites, like the Salomon S/LAB Phantasm,” says Airiau. “And now, with the S/LAB Spectur, we have a speed shoe for the rest of the running population. The people who have goals, but winning is not one of them.” The Project: Speed FOR ALL To create the S/LAB Spectur, sports scientists at the Salomon Sport and Consumer Sciences Lab in Annecy, France, tested more than 200 different runners over more than two years in a project they called “The Democratization of Speed.” The goal was to help everyday runners win their own race. The team started the project with a study that has since been published in the European Journal of Applied Physiology (Chollet et al. 2022). First, they administered various physiological (oxygen consumption/energy expansion), biomechanical (stability and gait analysis) and sensory (assessment of heel stability and heel cushioning) tests to elite and non-elite runners running in popular “super shoes” that are designed for elite runners. “Since 2016, most brands were innovating with carbon-plated running shoes, but we thought maybe not all the people using them might be benefiting from them, so that was really the starting point,” says Airiau. “The speeds of elite runners and everyday runners are different, and the needs are completely different as well. Normally, the two groups do not have the same body shape or the same stride, meaning the technical answers that we bring to those sets of runners should be different. And that was the reason why we created S/LAB Spectur.” With the Sports Science Team, Salomon’s footwear R&D experts developed multiple prototype models of the shoe that would become the S/LAB Spectur, adjusting the shoe’s features along the way and measuring the effects on everyday runners using the same physiological, biomechanical and sensory tests to see what designs aided performance (and which impeded). When everyday runners performed the running test with both the S/LAB Spectur and one of the best-selling shoes on the market, the team discovered that the runners were able to reduce their oxygen consumption while using the S/LAB Spectur.* “If you improve your efficiency, you save more energy and run faster later in the race,” Giandolini says. “Let’s say you are running at 10 km/hour. If you reduce your oxygen consumption by 4%, you may, in theory, increase your running velocity by approximately 4.5%. That could translate to a 7-minute gain in your marathon finishing time.” The S/LAB Spectur will be available on Salomon.com and at select specialty retailers in May 2024.

Similarly, James Watson and Francis Crick discovered the double helix of DNA in 1953. Today, as genetics underlies all modern biology, it is astonishing that a small change in one’s DNA dramatically alters one’s perception of the world. The most profound question is why the genes for synesthesia remain so prevalent in the general population. Remember that about one in 30 people walk around with a mutation for an inwardly pleasant but apparently useless trait. It costs too much in wasted energy to hang on to superfluous biology, so evolution should have jettisoned synesthesia long ago. The fact that it didn’t means that it must be doing something of inapparently high value. Perhaps the pressure to maintain it stays high because the increased connectivity in the brain supports metaphor: seeing the similar in the dissimilar and forging connections between the two. Understanding the laws behind the ability could give us an unprecedented handle on the development of language and abstract thinking, to say nothing of creativity.Popular Science, 10d ago

...• List of Machinery ProviderVitamin C supplement is a supplement that provides a concentrated dose of vitamin C, a water-soluble nutrient and powerful antioxidant. Vitamin C, or ascorbic acid, is essential for various bodily functions, including immune support, collagen production, and antioxidant defense. One of the main benefits of vitamin C supplements is their role in supporting the immune system. Vitamin C strengthens the immune response, helping the body defend against infections and illnesses. It boosts the production of white blood cells and antibodies, aiding the body's ability to fight off pathogens. It is also crucial for collagen synthesis, a protein that supports the structure of the skin, bones, and connective tissues. Vitamin C supplements promote collagen production and promote healthy skin, joint flexibility, and overall tissue repair. Furthermore, as an antioxidant, vitamin C helps neutralize free radicals, unstable molecules that can cause oxidative stress and damage cells. This antioxidative property of vitamin C may help protect against chronic diseases and support overall cellular health. The human body does not naturally produce it. While it is abundant in many fruits and vegetables, some individuals may have difficulty obtaining adequate amounts from their diet alone. In such cases, vitamin C supplements offer a convenient and reliable way to ensure sufficient intake of this essential nutrient. They offer valuable immune support, collagen synthesis, and antioxidant benefits, making them popular for individuals seeking to enhance their health and well-being. Vitamin C supplements can be beneficial to a healthy lifestyle when used responsibly and in conjunction with a balanced diet.The market has witnessed significant growth in recent years, driven by several key factors. The increasing awareness of the importance of vitamin C in supporting the immune system has been a major driver. As individuals become more health-conscious and seek ways to boost their immunity, the demand for vitamin C supplements has risen. The COVID-19 pandemic has further heightened this awareness, with many individuals looking to fortify their immune defenses. Furthermore, changing patterns and busy lifestyles have contributed to the popularity of vitamin C supplements. With modern diets often lacking in fruits and vegetables rich in vitamin C, individuals may turn to supplements as a convenient means of meeting their recommended daily intake. Moreover, the beauty and skincare industry has played a role in driving the market. Vitamin C's role in collagen synthesis and its antioxidant properties have made it a sought-after ingredient in skincare products. As a result, there has been an increase in demand for vitamin C supplements for both oral consumption and topical application for skin health benefits. The growth of e-commerce and online retail has also contributed to market expansion. Consumers can easily access vitamin C supplements from various brands, comparing prices and reviews for informed purchasing decisions. Additionally, healthcare professionals, social media influencers, and celebrity endorsements have positively impacted consumer perception and confidence in vitamin C supplements, further catalyzing the market.Browse Full Report with TOC: https://www.imarcgroup.com/vitamin-c-supplement-manufacturing-plant-project-report Key Insights Covered the Vitamin C Supplement ReportMarket Coverage:• Market Trends...openPR.com, 3d ago
The success of the biobag animal trials raised the possibility that these health complications could be prevented and that a neonate born nearly four months before their due date could recover in good health. An extremely premature lamb fetus was placed inside a translucent polyurethane bag and was buoyed by artificial amniotic fluid. Like the fluids that surround a baby in a pregnant person’s body, this synthetic liquid delivered nutrients to the neonate. After much trial and error, researchers were able to use an external pump that fed oxygen into the biobag and flushed out toxins to create a workable approximation of the placenta, the extraordinary organ that grows in pregnancy to connect the fetus to the uterus. The technology ultimately allowed scientists to successfully gestate lamb fetuses from the equivalent of approximately twenty-two to twenty-four weeks in a human until they were fully developed (at the equivalent of around twenty-eight weeks) and could be extracted in good health. In 2019, the group announced a second round of promising animal trials. The process of securing Food and Drug Administration approval for trials with human fetuses is now under way, with hopes that this work might begin within the next few years.The Walrus, 3d ago
The future of medicine is shifting to cloud computing, where health care providers can access patient information from anywhere at any time. This transformative shift will facilitate rapid and efficient treatment decisions, which can be crucial in emergency situations. As the fields of AI and neuroscience advance, the development of methods to interpret brain activity becomes increasingly imminent. Recent studies have already demonstrated the feasibility of such interpretation for specific brain regions. Decoding patterns of neural activity will unlock insights into the underlying mechanisms of cognitive function and behavior, potentially revolutionizing medical treatments. However, these developments also present challenges to HIPAA regulation and raise additional privacy concerns for intellectual property derived from this information. Moreover, a basic goal of integrating AI into the medical field is to train agents to identify abnormal brain scans. To do this, datasets must be expanded by several orders of magnitude, because medical diagnoses often are highly individualized with significant variability in symptom characteristics. Ensuring data security is crucial in protecting patients’ privacy and encouraging participation in neuroimaging studies. Ultimately, the integration of AI and cloud computing has the potential to revolutionize various aspects of health care. Giordano’s research will help address a vital step toward this goal: the creation of a secure encryption method capable of handling large medical imaging file formats while preserving the content and patient privacy.newswise.com, 3d ago

Newswise — Microorganisms, such as bacteria and sperm, can undergo adaptive shape morphing to optimize their locomotion mechanisms in the environment, which enables them to navigate complex barriers and improve survival. Inspired by this autonomous behavior, artificial reconfigurable microrobots have been proposed to realize similar adaptation capabilities.Helical microswimmers are particularly promising for biomedical applications because of their unique propulsion mechanism. Under a rotating magnetic field, helical microswimmers can transition dynamically between tumbling and corkscrewing motions, allowing them to navigate complex terrain and achieve targeted drug delivery.In a new paper published in Light: Applied Manufacturing, a team led by Professor Jiawen Li from the University of Science and Technology of China has developed new ways to make helical microswimmers that are very small, with dimensions in the micrometer range. This is important because many biological structures, such as cells, capillaries, and wrinkles on cell surfaces, are also very small.Microscale helical microswimmers are promising tools for biomedical applications, such as drug delivery and targeted therapy. However, some challenges still need to be addressed before these microswimmers can be widely used in clinical practice.One challenge is the fabrication of microscale helical microswimmers. Femtosecond direct laser writing (fs-DLW) is a powerful tool for fabricating complex 3D structures with high resolution, but it is a slow and inefficient process. This makes it difficult to produce large quantities of microswimmers quickly.Another challenge is the adaptive locomotion of microswimmers in complex environments. Inside the body, pH values vary among different tissues, and numerous microchannels and obstacles exist. Microswimmers need to be able to sense their environment and adapt their locomotion accordingly to reach their target destination.Researchers are addressing these challenges. One approach is to develop new fabrication methods that are more efficient and scalable than fs-DLW. Another approach is to design microswimmers that are more responsive to environmental stimuli and can adapt their locomotion accordingly.In this study, researchers developed a new method for fabricating pH-responsive helical hydrogel microswimmers. This method is called rotary holographic processing and is much faster than traditional methods. It can produce microswimmers in less than a second, approximately one hundred times faster than the point-by-point scanning strategy.The microswimmers are made of hydrogel, which is a type of material that can absorb water. This makes the microswimmers responsive to pH changes. When the pH of the surrounding environment changes, the microswimmers change shape. This shape change allows the microswimmers to move in different ways.Under a constant rotating magnetic field, the microswimmers can tumble or corkscrew. The type of motion depends on the pH of the environment. In a low pH environment, the microswimmers contract and tumble. In a high pH environment, the microswimmers expand and corkscrew.The researchers assessed the microswimmers in various conditions and found that they could traverse complex terrains and deliver drugs to targeted cells. This suggests that rotary holographic processing is a promising method for fabricating microswimmers for biomedical applications.This research suggests that rotary holographic processing is a promising new method for fabricating microswimmers for biomedical applications. The microswimmers are fast, reconfigurable, and able to navigate complex environments. This makes them ideal for targeted drug delivery and cell therapy tasks.newswise.com, 3d ago

Newswise — Ana Mateos and Jesús Rodríguez, scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have published a paper in the journal Palaeogeography, Palaeoclimatology, Palaeoecology which shows that large herbivore carrion, a resource that had formerly been abundant and accessible to hominins, became scarcer at the end of the Early Pleistocene due to changes in the Iberian fauna.Hominins arrived in the Iberian Peninsula about 1.4 million years ago, where they found a wide variety of food resources including a great abundance of carcasses of large herbivores partially consumed by a diversity of predators, important among which were two species of sabre-tooth cats (Homotherium latidens and Megantereon whitei).They also encountered a powerful competitor in these ecosystems, the giant hyena (Pachycrocuta brevirostris). However, as the same authors showed in earlier work, the wealth of food and diversity of the ecosystems at this period made the coexistence of hominins and giant hyenas competing for carrion possible.That being said, around one million years ago there were major climatic changes which restructured the ecosystems of the whole of Europe. In the Iberian Peninsula, the large mammal fauna suffered the extinction of several species, including the giant hyena and one of the sabre-tooth cats (M. whitei), leading to lower availability of carrion.Virtual simulationsThe researchers employed a computational model which enables experiments in a virtual environment that simulate the behavior of hyenas and hominins competing for carrion. Each experiment represents a different ecological scenario, defined by the predator species present, the productivity of the ecosystem, and the competition for carrion with other species like vultures or small carnivores.“The giant hyenas and hominins could coexist in competition for carrion prior to the extinction of the sabre-tooth Megantereon and other predators, like the lycaons (canids) and pumas. However, after those predators disappeared carrion became scantier. This coincides with the extinction of the giant hyena”, explains Mateos.According to the results of these experiments, among the key factors that determined these changes were the low productivity of the ecosystems during the very cold intervals of the period, strong competition with scavengers other than the giant hyena, and the likely social behavior of the other great sabre-tooth (H. latidens).Unlike hyenas, which would have depended exclusively on large herbivore carcasses for food, hominin behavior would have been much more flexible as they could also exploit plant resources like fruit, berries or roots, hunt small animals and even kill larger ones.“This greater flexibility in procuring food would have allowed them to survive and adapt to the new prevailing ecological conditions following the changes in the climate and fauna one million years ago”, adds Rodríguez.The only participant in this paper from outside the CENIEH was Ericson Hoelzchen, a scientist at the German Research Center for Artificial Intelligence (DFKI), at Trier University (Cognitive Social Simulation Lab). This work forms part of the project TROPHIc (PID2019-105101GB-I00, MCIN/AEI/ 10.13039/501100011033).newswise.com, 3d ago
Newswise — Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules that in the future could potentially be developed into a stroke recovery therapy. “Communication between nerve cells in large parts of the brain changes after a stroke and we show that it can be partially restored with the treatment”, says Tadeusz Wieloch, senior professor of neurobiology at Lund University in Sweden.“Concomitantly, the rodents regain lost somatosensory functions, something that around 60 per cent of all stroke patients experience today. The most remarkable result is that the treatment began several days after a stroke,” Wieloch continues.In an ischemic stroke, lack of blood flow to the brain causes damage, which rapidly leads to nerve cell loss that affects large parts of the the vast network of nerve cells in the brain. This may lead to loss of function such as paralysis, sensorimotor impairment and vision and speech difficulties, but also to pain and depression. There are currently no approved drugs that improve or restore the functions after a stroke, apart from clot-dissolving treatment in the acute phase (within 4.5 hours of the stroke). Some spontaneous improvements occur, but many stroke patients suffer chronic loss of function. For example, about 60 per cent of stroke sufferers, experience lost somatosensori functions such as touch and position sense.An international study published recently in the journal Brain and led by a research team from Lund University in collaboration with University of Rome La Sapeinza and Washington University at St. Louis, shows promising results in mice and rats that were treated with a class of substances that inhibit the metabotropic glutamate receptor (mGluR5), a receptor that regulates communication in the brain’s nerve cell network.“Rodents treated with the GluR5 inhibitor regained their somatosensori functions,” says Tadeusz Wieloch, who led the study published in BRAIN.Two days after the stroke, i.e. when the damage had developed and function impairment was most prominent, the researchers started treating the rodents that exhibited the greatest impaired function.“A temporary treatment effect was seen after just 30 minutes, but treatment for several weeks is needed to achieve a permanent recovery effect. Some function improvement was observed even when the treatment started 10 days after a stroke,” says Tadeusz Wieloch.Importantly, sensorimotor functions improved, even though the extent of the brain damage was not diminished. This, explains Tadeusz Wieloch, is due to the intricate network of nerve cells in the brain, known as the connectome, i.e. how various areas of the brain are connected and communicate with each to form the basis for various brain functions.“Impaired function after a stroke is due to cell loss, but also because of reduced activity in large parts of the connectome in the undamaged brain. The receptor mGluR5 is apparently an important factor in the reduced activity in the connectome, which is prevented by the inhibitor which therefore restores the lost brain function,” says Tadeusz Wieloch.The results also showed that sensorimotor function was further improved if treatment with the mGluR5 inhibitor is combined with somatosensory training by housing several rodents in cages enriched with toys, chains, grids, and plastic tubes.The researchers hope that in the future their results could lead to a clinical treatment that could be initiated a few days after an ischemic stroke.“Combined with rehabilitation training, it could eventually be a new promising treatment. However, more studies are needed. The study was conducted on mice and rats, and of course needs to be repeated in humans. This should be possible since several mGluR5 inhibitors have been studied in humans for the treatment of neurological diseases other than stroke, and shown to be tolerated by humans,” says Tadeusz Wieloch.The research is conducted with support from the Swedish Research Council, Alborada Trust, Hans-Gabriel and Alice Wachtmeister Foundation, and Multipark Strategic Research Area.newswise.com, 3d ago

Currently, we understand elements of the function of individual organs and systems, but one of the biggest challenges is understanding the integration across systems and organizational scales: linking laboratory-based studies of form, function and biomechanics to how animals behave in much more complex real-world environments. For example, how does muscle–tendon stiffness determine economy of movement, which then determines how an animal evaluates risks and rewards in its environment and then decides to navigate that environment. We have a big gap in our understanding at the organism/environment scale. There are people who study animal behaviour in their environment and the environmental factors that influence behaviour, but we don't have many approaches that directly link, in a mechanistic way, how the physiological systems in the body and the biomechanics of those systems influence the capacity to move in the environment and how animals choose to move depending on their own individual capacity. I think there's a rich opportunity to integrate between comparative biomechanics and animal behaviour, and between comparative biomechanics and wildlife ecology. New sensor and data logging technologies are now allowing scientists to do this, but this integration remains in the early stages. We now have miniaturized accelerometers with relatively long battery lives that can track animal movements, but we need physiological measures as well – measurements of heart rate, heat production and other physiological variables as animals move. Data storage and battery life are often limiting factors. It's really exciting to see how far the technology has come in the past 10 years, so I'm hopeful that we will get to the point where we have rich datasets from animals moving in natural environments that will inform our laboratory studies. We need to know what behaviours are most relevant to animals in the real world so we can investigate them in more mechanistic detail in the lab.The Company of Biologists, 3d ago

The intuitive area of our brain often knows the correct answer to a problem long before the analytical part. Data can be extremely useful for decision-making, but many leaders use it as a crutch or excuse to procrastinate, overthink, or say no and avoid taking a risk. If they listen to their gut—even if it contradicts the data—they will make faster, more effective decisions, usually with incredible upsides. In one study involving three dozen top CEOs, 85 percent confirmed that intuition—in the form of rules of thumb—was central to their decision-making process.CEOWORLD magazine, 3d ago
These findings have the potential to transform migraine treatment and provide hope for migraine sufferers. This research adds valuable insights to the field, contributing to our understanding of this debilitating condition.How can the results of your doctoral research be utilised in practice?The results of this migraine research offer a wealth of practical applications that could revolutionise the treatment of this common disorder. This doctoral research has identified innovative potential targets within the endocannabinoid system, which may lead to new therapies. By focusing on the specific endocannabinoid degrading enzymes MAGL and FAAH, this study holds the promise of developing drugs with fewer side effects, bringing new hope to migraine patients. Moreover, this research paves the way for practical applications in clinical settings, including experiments on human tissues. This project outcome inspires further exploration of endocannabinoid-based treatments in clinical studies. A novel application of the fluorescent dye FM1-43, to monitor and identify the function of Piezo1 channels in specific cell types involved in migraine pain has emerged from this study. In summary, these findings offer new solutions for more effective treatments of migraine pain and suggest an innovative monitoring tool, ultimately improving the quality of care for migraine patients.What are the key research methods and materials used in your doctoral research?A multidisciplinary approach was used in this doctoral research, including live calcium imaging to investigate the role of Piezo1 channels in trigeminal neurons and glial cells and innovative chemoproteomic method of Activity-Based Protein Profiling, providing valuable insights into the activities of endocannabinoid degrading enzymes across various regions of the central nervous system linked to migraines. This was complemented by electrophysiological recordings to directly assess action of endocannabinoids on nociceptive spiking in the meninges, where migraine pain originates. Various animal models and tissues were used along with unique human samples available via collaboration with Kuopio University Hospital.University of Eastern Finland, 3d ago
Evoked responses and oscillations represent two major electrophysiological phenomena in the human brain yet the link between them remains rather obscure. Here we show how most frequently studied EEG signals: the P300-evoked response and alpha oscillations (8–12 Hz) can be linked with the baseline-shift mechanism. This mechanism states that oscillations generate evoked responses if oscillations have a non-zero mean and their amplitude is modulated by the stimulus. Therefore, the following predictions should hold: (1) the temporal evolution of P300 and alpha amplitude is similar, (2) spatial localisations of the P300 and alpha amplitude modulation overlap, (3) oscillations are non-zero mean, (4) P300 and alpha amplitude correlate with cognitive scores in a similar fashion. To validate these predictions, we analysed the data set of elderly participants (N=2230, 60–82 years old), using (a) resting-state EEG recordings to quantify the mean of oscillations, (b) the event-related data, to extract parameters of P300 and alpha rhythm amplitude envelope. We showed that P300 is indeed linked to alpha rhythm, according to all four predictions. Our results provide an unifying view on the interdependency of evoked responses and neuronal oscillations and suggest that P300, at least partly, is generated by the modulation of alpha oscillations.eLife, 3d ago
More than a century of research, of which JEB has published a substantial selection, has highlighted the rich diversity of animal eyes. From these studies have emerged numerous examples of visual systems that depart from our own familiar blueprint, a single pair of lateral cephalic eyes. It is now clear that such departures are common, widespread and highly diverse, reflecting a variety of different eye types, visual abilities and architectures. Many of these examples have been described as ‘distributed’ visual systems, but this includes several fundamentally different systems. Here, I re-examine this term, suggest a new framework within which to evaluate visual system distribution in both spatial and functional senses, and propose a roadmap for future work. The various architectures covered by this term reflect three broad strategies that offer different opportunities and require different approaches for study: the duplication of functionally identical eyes, the expression of multiple, functionally distinct eye types in parallel and the use of dispersed photoreceptors to mediate visual behaviour without eyes. Within this context, I explore some of the possible implications of visual system architecture for how visual information is collected and integrated, which has remained conceptually challenging in systems with a large degree of spatial and/or functional distribution. I highlight two areas that should be prioritised in future investigations: the whole-organism approach to behaviour and signal integration, and the evolution of visual system architecture across Metazoa. Recent advances have been made in both areas, through well-designed ethological experiments and the deployment of molecular tools.The Company of Biologists, 3d ago
ChatGPT is not the end game, though, according to Jianfeng Feng, dean of the Institute of Science and Technology for Brain-Inspired Intelligence at Fudan University. In his commentary, “Simulating the whole brain as an alternative way to achieve AGI,” Feng argued that the ability of ChatGPT to outperform humans in certain tasks is not surprising — after all, a simple calculator can multiply large numbers quicker than a human. However, it is not an example of artificial general intelligence (AGI), a theoretical step beyond AI that represents human abilities so well it can find a solution for any unfamiliar task.SCIENMAG: Latest Science and Health News, 3d ago
Considering the possibility that other factors, such as human behavior and olfactory cues, may not have been completely eliminated in experiments I and II, we conducted an additional experiment under conditions of sound presentation with loudspeakers that could completely eliminate these factors. The results of the third experiment (Fig. 4A,B) support the assumption that vocalizations provided distress information to the receiver because fH increased by approximately 40% and reached a peak immediately after the onset of deviant DC stimulation during the EC-standard paradigm. Additionally, fH gradually returned to baseline within approximately 10 s after the offset of the stimulus. This time course of responses was similar to that of a previous study using aggressive social calls of a few seconds duration in the mustached bat, Pteronotus parnellii (Ma et al., 2010). However, DCs did not lead to an increase in fH during the DC-standard oddball paradigm, despite using the same stimuli (Fig. 3C,D). In other words, even with the same sound stimulus, the fH responses differed depending on the type of deviation. Therefore, there is no doubt that a context consisting of several DCs has a profound effect on the decision making of receiver bats via their autonomic nervous systems. Incidentally, we did not focus on sex or age differences in these responses because the sample size was not large enough to be statistically comparable. Future experiments will examine whether these factors elicit fH responses as different internal states. In summary, these results suggest the possibility that P. abramus may detect a distress situation from the vocalization context, and that the vocalization context affects the decision making of the receiver bats.The Company of Biologists, 3d ago

The journal's influence in comparative biomechanics continued into the next decade, with Claire Farley, James Glasheen and Thomas McMahon (all at Harvard University) measuring the reaction forces of animals ranging from a tiny kangaroo rat (∼100 g) to a horse (135 kg) to find out how the stiffness of muscle–tendon spring units varies with the animal's speed. Although speed had very little effect on the stiffness of energy-storing muscle–tendon springs, the size of the animal did, with the largest animal's elastic units being 100 times stiffer than those of the smallest creatures (Farley et al., 1993). However, a new trend emerged during the 1990s: studies investigating the physiological responses of animals to climate change began to appear. In 1992, R. S. Batty and J. H. S. Blaxter (Dunstaffnage Marine Laboratory, UK) used the phrase ‘climate change’ in the journal for the first time (Batty and Blaxter, 1992) and in 1996, Jonathan Stillman and George Somero (Stanford University, USA) first mentioned ‘global warming’ (Stillman and Somero, 1996). Three years later, Lars Tomanek (Stanford University) and Somero investigated the impact of high temperatures on three Tegula sea snail species, residing at different heights on the rocky seashore at the Hopkins Marine Station. Although they discovered that all of the snails had some ability to acclimate to higher temperatures, it was clear even in the late 1990s that some were already living close to the highest temperatures that they could endure and were potentially at risk as environmental temperatures continued to climb (Tomanek and Somero, 1999).The Company of Biologists, 3d ago

The main research focus of the lab is to understand the development of the hypothalamus in the ventral forebrain. The hypothalamus mediates homeostasis. It is crucial for the survival of the individual and the survival of the species, yet very few labs in the world focus on hypothalamic development. Arguably, amongst the different regions of the brain, we understand its development the least. The reason for this is that the developing hypothalamus is relatively tiny, morphologically complex and develops deep down in the brain in a region that is difficult to access and visualise. For these reasons, we use the chick as a model organism, where the developing hypothalamus is relatively large in comparison to mouse and zebrafish. A main finding from our research is that the hypothalamus develops through a mechanism in which growth and patterning are intrinsically linked, that the ventral forebrain in sculpted in a very different manner to the dorsal forebrain and that hypothalamus development is closely linked to eye development. This work will have wide implications for our understanding of how particular cell types in the hypothalamus develop, where they originate and who their neighbours are at any particular point in time in development.The Company of Biologists, 3d ago

So there's, there's often a perception among people that the genome of an organism in some way fixes it toward a specific set of structures and functions. And so when you say, Okay, why do we have five fingers on each hand? Why do we have a certain body plan, you say, well, the gets the DNA, the DNA, determines it. But the interesting thing is, as we're finding out now is that the DNA specified, the DNA doesn't actually specify morphology directly, or anatomy directly, the state of the DNA specifies the tiny hardware, the proteins that every cell gets to have. And so what we are now starting to understand is the software that's actually able to be implemented by cells bearing that hardware. And the amazing thing is that evolution has produced hardware that can do more than one thing. And our lab and various other I mean developmental plasticity, something that people have studied for a long time, in other words, different outcomes in different environments. But we, in our lab, have really been focusing on this idea of where is the information stored for large scale shape in the in the form of pre patterns, and some other people study pre patterns that are chemical we study, in particular bio electrical pre patterns. And these are very analogous to memories that you might have in your brain about where you're going to physically go. And in similar ways we've shown and others have shown that there are pre patterns, there are electrical pre patterns in cell sheets that say, where are these groups of cells going to go in terms of anatomy, what are they going to make, and so a lot of that is reprogrammable. And this is why we've made tadpoles that we can induce the eyes, on the guts and on the tails of tadpoles, we can make flatworms with heads that belong to other species, you can make all these changes, because the hardware is reprogrammable. It's willing to do other things besides its standard default. And that that plasticity, that reprogram ability is really critical. And for that we have to go beyond kind of where all of modern molecular medicine is, which is aimed at the the genome editing and and, you know, pathway engineering and things like that. And really try to understand the collective intelligence, the decision making of groups of cells, how do they use that hardware to make decisions on their journey through all the possible anatomies and functions?...newswise.com, 5d ago
In my work with addiction, I was struck by the self-harm aspect of the condition. This led to my wondering in more detail why humans are the only species that self-harms. While I could comprehend a part of the brain being addicted to nicotine, alcohol, or an opiate, I could not comprehend the concept of being addicted to self-harm. This then led me to research the evolution of the part of the brain called the amygdala, the fight or flight area of the brain that exists in all mammals. This in turn lead me to examine the way the human amygdala (seat of aggression) differs from the amygdala of other mammals. Noteworthy, is that it directs aggression both inwardly and outwardly. Inner directed aggression is at the core of a huge percentage of our human psychic suffering. The study of the amygdala then led me to the pre-frontal cortex, the seat of inner self-awareness, and the realization that the pre-frontal cortex could be educated and trained to be aware of the inner-directed aggression. This then led me to the development of a brain education-based mindfulness training program that is outlined in my book, Me Myself & My Amygdala: A Mindfulness Guide to Sobriety & Recovery. Inviting our patients to learn and have conversations about the human brain is a creative, nonthreatening approach to concretely help our patients in the development of insight. While looking into the brain is a rather literal form of insight, it is a starting point and a glimpse into our shared humanity.Psychiatric Times, 20d ago
Kuhl, a professor and co-director of the Institute of Learning & Brain Sciences at the University of Washington, and her team first took neuroimaging measurements of the participants’ brains in 2018. The researchers then compared the amount of brain thinning in 2021 with a computer model of what would usually be expected three years after the point at which the first measurements were made. The cortex normally gets thinner as an adolescent grows, but the model showed a sped-up pattern of thinning during the pandemic. The effect was much more noticeable in female adolescents in the 68 brain areas measured. “The magnitude of this shift in [female adolescents] is quite large,” Kuhl said. “A girl who visited the lab, on average, at age 11 and then returned to the lab for time two at age 14 showed the age of a 16-year-old.”...Scientific American, 17d ago
The Human Brain Project's goals have always been more diffuse: "The Human Brain Project has contributed to a deeper understanding of the complex structure and function of the human brain with a unique interdisciplinary approach at the interface of neuroscience and technology." While BRAIN's atlas is revolutionary in its identification of cell types and functions, the Human Brain Project's equivalent is more expansive, modeling brain activity that may provide insight into a variety of fields, including robotics, artificial intelligence, neural implants, and the study of consciousness.Psychology Today, 22d ago
Microbial interactions have a vital role in human health and disease. In the vagina, lactobacillus bacteria inhibit strict anaerobes while microbial imbalances may result in recurrent bacterial vaginosis. In the nasopharynx, the human pathogen Streptococcus pneumoniae (Spn) asymptomatically colonizes as a commensal, yet disseminates to the blood, brain, ear, and lungs to cause disease. Although infection is often detected at the macroscale, bacteria first colonize and interact with members of their community at high local densities at the microscale before the infection progresses to a detectable level. To investigate how bacteria interact at the microscale I adapted and implemented a microfluidic platform that enables high-parallel cultivation of bacteria to dissect and characterize microbial interactions. Cultivation takes place in aqueous droplets suspended in oil emulsion, creating thousands of monodisperse mini-bioreactors. My dissertation evaluated and validated microdroplets as an effective tool for recapitulating interactions between two common vaginal bacteria and developed a novel ex-vivo model system to culture the common and fastidious vaginal bacterium, Lactobacillus iners, in droplets containing vaginal fluid. My postdoctoral work focuses on developing a microfluidic device that keeps droplets static to investigate single-cell dynamics of a cell-signaling virulence determinant in Streptococcus pneumoniae. This technology enables measurement of cell density and assessment of the effect of environmental cues on signaling at the single-cell and population levels, as well as the role of heterogeneity as it emerges within and across populations. This microfluidic platform provides detailed single cell, pairwise interaction, and micropopulation-level insight that is not attainable using conventional techniques. The work will inform how cell-cell communication contributes to disease, and will help develop new diagnostics and therapeutics.myUMBC, 14d ago
We have replicated our unbiased screen for molecular correlates of sleep pressure and show that serotonin, a biogenic amine that has long been implicated as a sleep promoting substance in both mammalian and fly brains, meets the criteria for a sleep substance within the central brain of Drosophila. This finding would appear to reconcile conflicting observations regarding serotonin’s role in sleep regulation (see Jouvet 1999 Neuropsychopharmacology Vol. 21, p. 24). We think that this result will be of major interest to the field and will be the basis of a great deal of future work. While we find the reviewer’s comments regarding our re-evaluation of sleep definition in the fly encouraging, we must reiterate that although we agree ‘active sleep’ likely represents a discrete sleep stage in the fly that is likely relevant to sleep homeostasis, it would not be possible to examine it with yoked controls simply owing to the logistical issues associated with yoking (i.e., the frequency of simulation necessary to prevent it; see figure above) would make it impossible for yoked controls to get enough sleep to serve as meaningful controls for mechanical stimulation. Nevertheless, we agree that future studies should address the important question of homeostatic control of the active sleep state.eLife, 20d ago

In contrast to that in other species (e.g. fruit flies – Fedele et al., 2014; Toma et al., 2002), gravisensation in monarchs appears to be a light-independent process, as they were able to right themselves in complete darkness in our study. Gravity cues appear to be sufficient for oriented behavior (righting behavior), as monarchs do not have access to other cues in darkness that can provide directional information, such as the vertical component and vector of the magnetic field (Putman et al., 2018). Our results therefore suggest that gravisensation in monarchs is potentially based on a mechanosensory system. We found that the antennae act as important morphological structures for sensing gravity, with intact antennae necessary for upwards orientation and negative gravitaxis. For example, in our experiments in which monarchs had their antennae removed (righting response trials), monarchs no longer shifted their orientation and movement upwards (0 deg) but instead displayed positive phototaxis as they directed their movement towards the position of a directional light source (light source coming from the left, and perpendicular to the vertical plane; Fig. 7). In monarchs, gravity might be sensed by the antennae, as they possess organs that are responsible for gravisensation, as found in other insects (Johnston's organ: fruit flies – Armstrong et al., 2006; Sun et al., 2009; ants – Vowles, 1954; mosquitoes – Boo and Richards, 1975) and are involved in maintaining proper body positioning during movement in other Lepidoptera (Bohm's bristles: flight stabilization in Lepidoptera – Sane et al., 2007). As gravity acts on the antennae, the movement and position of the antennae themselves might enable monarchs to determine upwards and downwards. For instance, the Bohm's bristles are hair plates located at the base of the antennae, which are capable of providing gross localization information about where the antennae are in relation to the head of the butterfly (Sant and Sane, 2018). Additionally, as the antennae are physically separated paired sensory organs that can move independently of one another, monarchs might be comparing the information provided by them for upwards directionality, in a similar manner to the way in which they use independent timing information from each of the antennae during time-compensated sun compass use (Guerra et al., 2012). Given the role of the antennae for gravisensation and their overall morphology (a long, thin flagellum with a much larger club-like section at the distal end), future studies with monarchs might focus on determining the relative torque experienced by the antennae during body orientation positioning, and investigate the electrophysiological responses of neurons downstream from antennal structures. These studies would help elucidate how the brain encodes body orientation and directionality and provide a promising route for understanding how this information is encoded.The Company of Biologists, 3d ago
In this study, we investigated the use of antennal movements in olfactory sensing. We show that cockroaches locate and track static and moving odours by shifting the antennae towards the plume centre where local high-frequency movement bouts are carried out. Interestingly, however, long-range scanning sweeps continue throughout, such that the overall sensory range covered is not significantly impacted. Consistent with previous findings, during intermittent pausing bouts (potentially akin to the slow walking movements in this study), cockroaches displayed wide uncorrelated vertical and horizontal movement, presumably favouring the discovery of environmental cues (Okada and Toh, 2004). With odour presentation, cockroaches displayed changes in behaviour in an odour- or valence-dependent manner: enhanced antennal movement and decreased walking speed for attractive odour stimulation (sex-pheromone in Nishiyama et al., 2007, and colony odour here), which are inverted for an aversive odour stimulus (Nishiyama et al., 2007). Our current study did not include highly aversive odours, but the weaker antennal responses (Figs S2B, S3C) and slight increase in walking speed (Figs S1C, S3A) in response to our low valence odour (linalool) nevertheless indicate an overall consistent antennal sampling behaviour (Figs 3, 4Biii,Ciii, 5). Upon odour detection, a general increase in fast movement components was observed, with rapid vertical strokes exhibited most prominently during the stimulus presentation, and increased horizontal sweeps that also continued after stimulus termination. A similar increase in oscillation frequency has recently been reported in bumblebees (Claverie et al., 2023), corresponding to frequencies of optimal odour capture rates (Claverie et al., 2022). Utilising both numerical simulations and particle image velocimetry (PIV) experiments with artificial antennae, Claverie et al. (2022) (see also Su et al., 2019, and Reidenbach et al., 2008) demonstrated that the air flow vortexes generated by antennal oscillations can enhance the transport and adsorption of odour molecules through the sensory pores. In agreement with that, our in vivo visualisations of the flow and odour concentrations around the cockroach antennae provide empirical evidence that these thin appendages create significant flow fluctuations. Additionally, our results of increased movement frequency with odour detection are reminiscent of the antennal behaviour towards tactile stimuli (Okada and Toh, 2006), where an increase in contact frequency occurred with object detection, indicating an increased accuracy of orientation toward the object.The Company of Biologists, 3d ago

To understand addiction, researchers typically look at neurons firing or molecular signatures across the brain, but these tools cannot nail down specific addiction-related molecules in different cell types. To get a more detailed understanding of addiction’s molecular underpinnings, in a study recently published in Nature Genetics Telese and her collaborators used single cell resolution technologies to better understand cocaine addiction in a diverse pool of rats.2 Focusing on the amygdala, the part of the brain involved in emotions and memories, they found that many molecular markers of addiction relate to how cells generate and use energy, which may point to a treatment for addiction-related behaviors.The Scientist Magazine®, 3d ago
Currently, rodents and songbirds are the dominant animal models of vocal communication in the field of animal psychophysiology – there are very few animal psychophysiological studies using bats as a model animal. In this study, we applied a psychological paradigm, the auditory oddball task, to bats for the first time. We found that their heart rate varied more in response to the context of the social call than to the surprise effect of the acoustic presentation. It would be very significant if this approach could be used not only in conventional animal models but also in bats, which have a decision-making mechanism based on sound information. We hope that animal psychophysiological research using vocal communication in bats will continue to develop.The Company of Biologists, 3d ago

One of the consumer trends is just understanding what the gut is. That's such a huge area. Finding out what prebiotics and probiotics are and how do they affect the gut? There’s the gut–brain axis, the gut–brain–skin axis. I've even read about the gut–kidney axis. How it affects cognition, how it affects depression, just a whole host of different areas. So just understanding what the gut is, to understanding what some of the formulations and ingredients are, and then understanding how the gut affects different areas in the body. I think that that is one of the biggest trends here, understanding the effects of all the different bacteria. There's over 100 trillion bacteria. We are more bacteria than we are actually human.

Daiken Biomedical maintains complete transparency about its ingredients, and its products have earned numerous international certifications from the authorities in recent years. In 2023, they achieved the remarkable milestone of receiving 13 Anti-Additive Clean Label Certifications, which speaks volumes about their dedication to ensuring the purity of the ingredients used for their products. Certified by Anti-Additive Clean Label Certification The A.A. Clean Label (ANTI-ADDITIVE CLEAN LABEL) Certification is a rigorous global standard for certifying products free from additives. Products that receive this certification are recognised for their safety, including the absence of harmful substances and compliance with environmental and health regulations throughout their production and packaging processes. Daiken Biomedical's Lutein Recognised with the A.A. Clean Label Certification in 2023 In 2023, Daiken Biomedical's flagship product, Lutein, was also certified by the A.A. Clean Label Certification in recognition of its purity and high quality. Additionally, Daiken Biomedical conducted extensive human clinical trials in partnership with international teaching hospitals and medical schools. After 18 months, Lutein demonstrated significant benefits in protecting eye health; research showed that within just 28 days, Lutein could increase the body's lutein concentration by 520%, significantly enhancing eye moisture by 190%. These impressive results indicate Daiken Biomedical's dedication to creating safe and effective health products. These findings were shared at the 22nd International Congress of Nutrition in Tokyo, Japan, in 2022, and the product has been awarded the Monde Selection Grand Gold Quality Award for two consecutive years, reflecting Daiken Biomedical's exceptional commitment to health product quality. Daiken Biomedical's Lutein is made up of a 'Golden Formula' containing seven ingredients, including FloraGLO® Lutein and ZeaONE® Zeaxanthin, both backed by a wealth of research and approved by The European Food Safety Authority (EFSA). It also includes MaquiBright®Maqui Berry and BS7®Bilberry, which are rich in anthocyanins, the potent antioxidant AstaZine®Astaxanthin, flaxseed oil, and vitamin E. These ingredients work together to comprehensively support vision and eye health. Ophthalmologist Recommends Three Steps to Select Top-Tier Lutein for Effective Dry Eye Relief With numerous eye care products like lutein available on the market, how should consumers choose the right one? Ophthalmologist Dr. Yun-Chen Chen, from Taiwan, recommends three selection principles to determine the most effective lutein supplements for combating dry and tired eyes in today's lifestyle, characterised by extensive use of electronic devices that rapidly depletes lutein. These guidelines help ensure the body receives the necessary nutrients. Principle 1: Free-Form Lutein and the Optimal Ratio Health supplements contain lutein in two forms: free-form and esterified form. Dr. Chen explains that esterified lutein requires digestive enzymes for absorption and is best taken with fats, which may not be suitable for individuals with digestive issues to consume. The molecular weight of free-form lutein is roughly half that of the esterified form; as a result, it is typically considered by the academic community to have a better absorption rate. The "Golden Ratio" refers to the optimal ratio of 10 mg of lutein to 2 mg of zeaxanthin, as determined by the five-year AREDS2 study conducted by the National Eye Institute in the U.S., to be the most beneficial for the human body. Daiken Biomedical's Lutein is created in collaboration with the U.S.-based Kemin Industries, which possesses multiple patented technologies, to produce a product with the golden ratio of FloraGLO® free-form Lutein and ZeaONE® free-formZeaxanthin used in U.S. NIH clinical trials. Furthermore, FloraGLO® Lutein is the most effective ingredient available on the market, supported by the research. Clinical data demonstrated a 520% increase in the body's lutein content after 28 consecutive days of consuming FloraGLO® Lutein. Principle 2: The Benefits of Complexes of Lutein with Maqui Berry and Bilberry as Ingredients In addition to lutein, Dr. Yun-Chen Chen suggests that combining lutein products with complex ingredients such as anthocyanins and astaxanthin can help maintain long-lasting moisture and brightness of the eyes. MaquiBright® Maqui Berry assists in regulating tear gland function and relieving dry eye symptoms, while BS7® Bilberry provides excellent antioxidant benefits, maintaining normal eye pressure and preventing night blindness. AstaZine® Astaxanthin helps reduce eye fatigue and pressure, which is beneficial for glaucoma care. Flaxseed oil and vitamin E are also excellent supporting ingredients, enhancing the body's absorption of lutein. Principle 3: International Awards and Certifications Indicate Superior Product Quality Looking for high-quality lutein products with guaranteed effectiveness? Dr. Yun-Chen Chen recommends evaluating whether the product has received any awards or certifications. Daiken Biomedical's Lutein, for example, has been awarded the Monde Selection Grand Gold Quality Award for two consecutive years after a thorough evaluation by over a hundred global experts. In terms of certification and testing, the raw materials for Lutein are sourced from American Kemin Industries, a company with 16 global patents covering seeds, production processes, and effectiveness. Additionally, it has been certified by Eurofins, an international third-party testing service provider, for being free of the Hepatitis A virus. This certification ensures food safety and instils trust in consumers. Dr. Chen also notes that lutein's health benefits will not come into effect immediately; consistent supplementation after meals for 2 to 4 months or more is necessary for the benefits to take effect. The biomedical research team at Daiken Biomedical, consisting of doctors and medical experts specialising in biotechnology from the United States, Japan, and Taiwan, stays true to the mottos: "safety and high quality" and "always deliver sensible results." The team is committed to developing safe and effective health foods for you and your family. Daiken Biomedical invests over a million dollars annually in evaluation and inspection and is 100% transparent about its ingredients. Their products have repeatedly received certifications from international authorities, including 13 products, such as Lutein, that have been certified as additive-free and a total of twenty-two gold awards and trophies from Monde Selection for Many consecutive years. In the future, Daiken Biomedical will continue being dedicated to creating safe, pure, and sensible health food to help the community lead healthier lives.

No experiment I could possibly design today is more valuable than preserving the opportunity to pose a new experiment tomorrow, next year, or in a decade. My cohort of scientists has come up inspired by imagining what it was like for contemporaries of Darwin to encounter and compare global wildlife, or during the modern synthesis, as the invisible internal mechanisms of evolutionary genetics unfurled. Now, we stare down the prospect that, during our turn, we will have to watch the biosphere die. I have peers who set out to study ancient mass extinction events only to find that the conditions that precipitated ancient mass extinction events aptly describe events now. I have contemporaries who set out to discover new species by recording sounds in the rainforest, only to capture an eerie transition toward silence. I've done very little field work and I study hardy, laboratory-tractable species that aren't endangered or picky about where they live, but even I stopped finding butterflies at my best collection site after wildfires. In my 10 years in science, I think I've never been to any research conference, on any topic, without hearing my colleagues interject dire warnings into their presentations – and I've never attended a climate-focused conference. So, the most important research question is ‘will the species I hope to study – and a stable international society that can support research activity as I've known it – survive the next 50 years?' With that in mind, with ‘unlimited’ funding, the best thing I can imagine doing for science is to fight. I think of legal support for climate protesters; cultivating honest communication platforms that bypass corporatized media; criminalizing ecocide; eliminating fossil fuels fast; protecting democracy against regulatory capture; buying out and defending the recommended 30% of Earth's surface as nature reserves; facilitating socially just transitions to safely support humans in the remaining land.The Company of Biologists, 3d ago
The secondary adaptation of Cetacea to a fully marine lifestyle raises the question of their ability to maintain their water balance in a hyperosmotic environment. Cetacea have access to four potential sources of water: surrounding salt oceanic water, dietary free water, metabolic water and inhaled water vapour to a lesser degree. Here, we measured the 18O/16O oxygen isotope ratio of blood plasma from 13 specimens belonging to two species of Cetacea raised under human care (four killer whales Orcinus orca, nine common bottlenose dolphins Tursiops truncatus) to investigate and quantify the contribution of preformed water (dietary free water, surrounding salt oceanic water) and metabolic water to Cetacea body water using a box-modelling approach. The oxygen isotope composition of Cetacea blood plasma indicates that dietary free water and metabolic water contribute to more than 90% of the total water input in weight for cetaceans, with the remaining 10% consisting of inhaled water vapour and surrounding water accidentally ingested or absorbed through the skin. Moreover, the contribution of metabolic water appears to be more important in organisms with a more lipid-rich diet. Beyond these physiological and conservation biology implications, this study opens up questions that need to be addressed, such as the applicability of the oxygen isotope composition of cetacean body fluids and skeletal elements as an environmental proxy of the oxygen isotope composition of present and past marine waters.The Company of Biologists, 3d ago

In light of these challenges, many research teams are investigating molecular methods to coax HIV out of hiding and into view of the immune system. Driving expression of HIV is desirable because it makes the virus a target for destruction by normal immunological mechanisms, and the hope is that doing so will result in clearance of the latent reservoir. Many trials using latency reversal agents (LRAs) have been pursued in recent years. These methods must walk the tricky balance of causing enough immune activation to release the entirety of the hiding proviral reservoir without over activating the immune system and causing inflammation in fragile sites, such as the brain. Unfortunately, one in vitro study showed that even if 100% of a subset of T cells are activated, some perfectly competent proviruses remain tucked away. This suggests that cellular activation alone as a latency reversal strategy may not be sufficient to clear the viral reservoir.ASM.org, 3d ago
Karam, McInnis and Arms along with Michael Kaller (Louisiana State University) then scrutinised the fish's brains to see whether they could identify differences between the two groups of fish and discovered several brain regions – involved in making social decisions – that were activated differently in the confident and bullied males. These included a region that processes sensory information – which could help a male to assess the social circumstances – and triggers a second brain area, a part of the social decision-making network, which controls the fish's behaviour. Wayne says, ‘The unique pattern of brain activation in the social decision-making network of susceptible males suggests an important role in regulating vulnerability to repeated social defeat stress’. The team adds that understanding the simpler brain circuits that underpin how fish struggle with difficult social situations could also help us to unravel the mysteries of some human mental health conditions, which share many of the same basic brain circuits.The Company of Biologists, 3d ago
In addition to the physiological implications, this study opens up new perspectives on the conservation biology of Cetacea. Indeed, showing that the quantity of fish ingested by Cetacea, as well as their nutritional value (protein and lipid composition), are important parameters for maintaining the water balance in these organisms, could help to guide fishing policies in certain regions where Cetacea populations live. Going even further, this study raises questions about the future of Cetacea in the face of global warming. Rising ocean temperatures mean that certain species of fish will migrate to greater depths than cetaceans are able to dive to. So what impact will this scarcity of prey have on Cetacea populations? Will they migrate, at the risk of upsetting the food chains in certain regions of the globe, or will they disappear?...The Company of Biologists, 3d ago

The book starts with a drawing of a black fetus Slatman saw. “I suddenly realized that I had only seen white people in anatomical drawings until then, and I was shocked when I became aware of this. I wanted to know how this dominance had occurred. The individual is so important in the West, more than his or her relationship with the physical and social environment. I illustrate this using the history of healthcare; the emergence of individualization in healthcare began in anatomy in the early 19th century, so before neoliberalism. By starting to view anatomy as the basis for pathology, the expectation is that diseases are caused by certain sources of disease in the body. In the search for sources of disease, medicine has become increasingly refined over the last two centuries; from organ to tissue, from cell to DNA. This search is supported by various technological developments, including the invention of the stethoscope and the ability to sequence DNA. Due to the attention for this view of the individual body, the sick person is entirely cut off from everything outside of him or herself. Due to the emergence of statistics and the term ‘normal’, the 19th century gave rise to something called the ‘normal body’ in medicine. But this so-called normal body, that in modern medicine is simply termed ‘the body’ for convenience, refers to one specific form of embodiment: the body of a white male who is not old.”...Tilburg University, 25d ago
The mind refers to the personal experience of perceiving and thinking about words, emotions, thoughts, and more. It relies on the proper functioning of the human brain.

Larvae, of course, perceive not only high salt concentrations as punishing, but also other sensory stimuli such as bitter substances (quinines and caffeine), electric shock, temperature, mechanosensory input (vibration), and light (Aceves-Pina & Quinn 1979, Apostolopoulou et al 2016, Apostolopoulou et al 2014, Eschbach et al 2011, Gerber & Hendel 2006, Khurana et al 2012, Pauls et al 2010, von Essen et al 2011). However, the extent to which the DL1 cluster is involved in coding for most of these aversive teaching signals remains unclear. Currently, comparisons at the level of DANs can only be made for sensory inputs that are dependent on high salt or mechanosensation. Interestingly, similar to high salt concentrations, somatosensory information can also result in the establishment of aversive olfactory memory in larvae (Eschbach et al 2020). The transmission of these somatosensory teaching signals is orchestrated by mechanosensory neurons from the chordotonal organs, class IV multidendritic nociceptive neurons distributed along the body, and multisensory basin neurons (Hwang et al 2007, Jovanic et al 2016, Ohyama et al 2015, Tracey et al 2003). The connectome revealed that these mechanosensory neurons also link to the DL1 cluster through three to four interneurons and elicit the activation of DAN-d1, DAN-f1, and DAN-g1 (Eschbach et al 2020). Upon comparing the interneurons that relay high salt and mechanosensory information to the DL1 cluster, six pairs of interneurons are of critical significance, respectively. These pairs include FFN-20, FB2N-12, FB2N-19, FFN-23, FFN-29, and FB2N-15 for mechanosensory information (Eschbach et al 2020), and FB2N-12, FB2N-18, FB2IN-11, FB2IN-6, FFN-21, and FFN-24 for high salt concentrations (Figure 8; supplemental Figure 7, rightmost column). Interestingly, only one pair of interneurons - FB2N12 - is shared between the two types of information and the other five types are specific to the sensory modality. The wiring patterns of DAN input neurons exhibit a notable consistency, with a limited number of neurons dedicated to a specific sensory modality, and single neurons shared across different modalities. This results in a unique combination of cellular codes that are partly redundant and partly specific for the four DL1 DANs. While certain DANs may hold greater significance for a particular information, such as DAN-d1 for somatosensory information, the DAN-g1 cell appears to play a general central role for encoding an aversive teaching signal. DAN-g1 responds to all aversive stimuli tested thus far and its activity has proven informative for all aversive memories analyzed to date. In order to gain a deeper comprehension of the processing of diverse sensory modalities in the larval brain, it is crucial to broaden the analytical framework presented in our work to encompass visual stimuli, various bitter substances, and temperature stimuli.elifesciences.org, 20d ago

Abstract:Large language models (LLMs), deep neural networks with billions of parameters, are revolutionizing scientific research, particularly in chemistry, where traditional methods often involve lengthy and resource-intensive processes. Traditionally, scientific research follows a trial-and-error strategy, often requiring extensive time and resources. For instance, the drug development process requires an investment of ~15 years and $1 billion. However, the impracticality of exploring the vast space of possible chemical compounds through such methods reveals the need for a more efficient strategy. Data-driven methods offer an alternative way of addressing this paradigm to accelerate discovery in chemistry. More specifically, LLMs provide an even further paradigm shift by requiring only natural language as input. These models allow the use of natural language to interact with complex data, simplifying and speeding up research processes. Their applications extend to property prediction, molecule optimization, and efficient knowledge retrieval, demonstrating that language can effectively represent chemical data. Our research shows that language models can be applied to predict blood-brain barrier permeation and solubility with uncertainty. We deployed this model in an open web application to improve usability and reproducibility. Another result of our research shows how we can use natural language descriptions of chemical procedures to optimize their outcome. These are examples of how LLMs are not just reshaping the approach to chemical research but also significantly reducing the time and resources required for scientific breakthroughs. For this reason, our vision is that LLMs represent a significant step forward in how we do science nowadays and that language is the future for chemical representation.rit.edu, 13d ago
Newswise — When you eagerly dig into a long-awaited dinner, signals from your stomach to your brain keep you from eating so much you’ll regret it – or so it’s been thought. That theory had never really been directly tested until a team of scientists at UC San Francisco recently took up the question. The picture, it turns out, is a little different. The team, led by Zachary Knight, PhD, a UCSF professor of physiology in the Kavli Institute for Fundamental Neuroscience, discovered that it’s our sense of taste that pulls us back from the brink of food inhalation on a hungry day. Stimulated by the perception of flavor, a set of neurons – a type of brain cell – leaps to attention almost immediately to curtail our food intake. “We’ve uncovered a logic the brainstem uses to control how fast and how much we eat, using two different kinds of signals, one coming from the mouth, and one coming much later from the gut,” said Knight, who is also an investigator with the Howard Hughes Medical Institute and a member of the UCSF Weill Institute for Neurosciences. “This discovery gives us a new framework to understand how we control our eating.” The study, which appears Nov. 22, 2023 in Nature, could help reveal exactly how weight-loss drugs like Ozempic work, and how to make them more effective. New views into the brainstem Pavlov proposed over a century ago that the sight, smell and taste of food are important for regulating digestion. More recent studies in the 1970s and 1980s have also suggested that the taste of food may restrain how fast we eat, but it’s been impossible to study the relevant brain activity during eating because the brain cells that control this process are located deep in the brainstem, making them hard to access or record in an animal that’s awake. Over the years, the idea had been forgotten, Knight said. New techniques developed by lead author Truong Ly, PhD, a graduate student in Knight’s lab, allowed for the first-ever imaging and recording of a brainstem structure critical for feeling full, called the nucleus of the solitary tract, or NTS, in an awake, active mouse. He used those techniques to look at two types of neurons that have been known for decades to have a role in food intake. The team found that when they put food directly into the mouse’s stomach, brain cells called PRLH (for prolactin-releasing hormone) were activated by nutrient signals sent from the GI tract, in line with traditional thinking and the results of prior studies. However, when they allowed the mice to eat the food as they normally would, those signals from the gut didn’t show up. Instead, the PRLH brain cells switched to a new activity pattern that was entirely controlled by signals from the mouth. “It was a total surprise that these cells were activated by the perception of taste,” said Ly. “It shows that there are other components of the appetite-control system that we should be thinking about.” While it may seem counterintuitive for our brains to slow eating when we’re hungry, the brain is actually using the taste of food in two different ways at the same time. One part is saying, “This tastes good, eat more,” and another part is watching how fast you’re eating and saying, “Slow down or you’re going to be sick.” “The balance between those is how fast you eat,” said Knight. The activity of the PRLH neurons seems to affect how palatable the mice found the food, Ly said. That meshes with our human experience that food is less appetizing once you’ve had your fill of it. Brain cells that inspire weight-loss drugs The PRLH-neuron-induced slowdown also makes sense in terms of timing. The taste of food triggers these neurons to switch their activity in seconds, from keeping tabs on the gut to responding to signals from the mouth. Meanwhile, it takes many minutes for a different group of brain cells, called CGC neurons, to begin responding to signals from the stomach and intestines. These cells act over much slower time scales – tens of minutes – and can hold back hunger for a much longer period of time. “Together, these two sets of neurons create a feed-forward, feed-back loop,” said Knight. “One is using taste to slow things down and anticipate what’s coming. The other is using a gut signal to say, ‘This is how much I really ate. Ok, I’m full now!’” The CGC brain cells’ response to stretch signals from the gut is to release GLP-1, the hormone mimicked by Ozempic, Wegovy and other new weight-loss drugs. These drugs act on the same region of the brainstem that Ly’s technology has finally allowed researchers to study. “Now we have a way of teasing apart what’s happening in the brain that makes these drugs work,” he said. A deeper understanding of how signals from different parts of the body control appetite would open doors to designing weight-loss regimens designed for the individual ways people eat by optimizing how the signals from the two sets of brain cells interact, the researchers said. The team plans to investigate those interactions, seeking to better understand how taste signals from food interact with feedback from the gut to suppress our appetite during a meal.newswise.com, 12d ago

In seasonal environments, many animals, including insects, enter dormancy, where they are limited to a fixed energy budget. The inability to replenish energetic stores during these periods suggests insects should be constrained by pre-dormancy energy stores. Over the last century, the community of researchers working on survival during dormancy has operated under the strong assumption that energy limitation is a key fitness trait driving the evolution of seasonal strategies. That is, energy use has to be minimized during dormancy because insects otherwise run out of energy and die during dormancy, or are left with too little energy to complete development, reproductive maturation or other costly post-dormancy processes such as dispersal or nest building. But if energy is so strongly constrained during dormancy, how can some insects – even within the same species and population – be dormant in very warm environments or show prolonged dormancy for many successive years? In this Commentary, we discuss major assumptions regarding dormancy energetics and outline cases where insects appear to align with our assumptions and where they do not. We then highlight several research directions that could help link organismal energy use with landscape-level changes. Overall, the optimal energetic strategy during dormancy might not be to simply minimize metabolic rate, but instead to maintain a level that matches the demands of the specific life-history strategy. Given the influence of temperature on energy use rates of insects in winter, understanding dormancy energetic strategies is critical in order to determine the potential impacts of climate change on insects in seasonal environments.The Company of Biologists, 3d ago
Carpentier and Blondin question the physiological importance of human BAT during acute cold exposure, as the amount of BAT is relatively small in comparison with rodents and cold exposure invokes a multi-organ response (e.g., shivering thermogenesis) in which the contribution of BAT may be minor. Moreover, they raised concerns as to whether 18F-FDG uptake truly reflects BAT thermogenesis, particularly in older or diabetic subjects, arguing that glucose uptake and metabolism may not be directly coupled to thermogenesis. As such, they question whether there is sufficient evidence that BAT dysfunction contributes to development of metabolic disease. Substrate preference for BAT thermogenesis has been a topic of discussion. The development of improved stable isotope tracing techniques is now enabling investigators to elegantly trace nutrient fate and identify critical fuels of thermogenesis in adipocytes (12, 13). Emanating from these emerging studies is an appreciation of the flexibility of brown adipocytes with respect to fuel selection and the importance of nutritional state (fed versus fasted) in determining the preferred fuel choice (10). Multiple factors may influence substrate utilization in BAT. For example, mice display a diurnal rhythm of BAT thermogenesis, including rhythmic futile creatine cycling, which is highest during the start of the active/dark period (14). Diurnal BAT activity may be an important factor to consider when studying the therapeutic potential of promoting BAT activity. Other additional experimental factors may need to be considered in the study of BAT thermogenic activity, such as the duration of cold exposure.jci.org, 3d ago
The disparities in Colorado reflect the unequal access to trauma hospitals and emergency care across the American West.Dr. Julie Dunn, one of the authors of the study on Colorado trauma outcomes, said she has spent her career trying to dissuade people of the notion that every hospital emergency department is equipped to handle complex trauma. Her hospital, UCHealth Medical Center of the Rockies in Loveland, was designated as a Level I trauma center in July 2022.Dunn’s hospital receives patients from rural towns on the eastern plains of Colorado and from as far as several hours away in southwest Nebraska and Wyoming, where hospitals don’t have enough resources to treat severe bleeding. The condition those patients arrive in depends on whether the hospitals where they were stabilized had a surgeon on staff, Dunn said.Those small hospitals can usually resuscitate hemorrhaging patients, but they are not equipped to stop the bleeding altogether, said Dunn, who also leads a regional trauma committee for the American College of Surgeons that includes Colorado, Wyoming, Montana, Utah and the Dakotas.Because of the dearth of high-level trauma centers in this part of the country, the most seriously injured patients must first go to a lower level trauma center or non-trauma hospital, or travel longer distances, delaying treatment, Dunn said.Many of these states have the highest proportions of people dying before they reach a hospital, the analysis with the University of Alabama at Birmingham found.Parts of the South, including Arkansas and Alabama, also have high proportions of prehospital trauma deaths.The News’ analysis is based on a 2018 study that linked state levels of prehospital trauma deaths to timely access to high-level trauma centers. Dr. Zain Hashmi, a UAB trauma surgeon and the study’s lead author, said he often sees patients from rural parts of Alabama who are near death because of how long it took to reach him.“It’s really, really sad to see those patients, because we could have made a difference, truly,” he said.He also recognizes that little data is available on the circumstances of injured victims who die before reaching a hospital. Those patients may never be evaluated by a medical professional, and local rules dictate whether they undergo an autopsy.“That’s a big black hole of information right now,” Hashmi said.On the East Coast — where states are smaller, population density is higher and trauma centers are more available — fewer patients die before reaching a hospital. Some cities have outsized trauma resources. Boston, a city of less than 700,000 people, has five adult Level I trauma centers — more than the states of Oregon, Washington and Nevada combined.Dr. Joseph Amos, trauma medical director for Methodist Health System in Dallas, studied the growth of trauma centers in certain parts of the country for a 2021 paper published in Trauma Surgery & Acute Care Open. In one area of Florida, his research team discovered for-profit hospital systems were choosing to become trauma centers — not out of need but because funding was available for facilities that treated uninsured trauma patients.Nationally, no one regulates the placement or expansion of high-level trauma centers in the U.S. In Texas, they increased by nearly 40 percent over the last decade, according to Amos’ study.Dr. Ernest Moore sees a similar pattern in his city, where what was then called Denver General Hospital used to be one of two trauma centers in the metro area. Now, the city has “so many I couldn’t count.” The duplication of services hampers research and education. When hospitals treat larger numbers of patients, trauma specialists gain expertise and patient care improves, Moore said.Meanwhile, other parts of the state remain starved of resources. The News’ analysis shows about 82 percent of trauma victims in Gunnison County, home to around 17,000 people in the heart of the mountains, died before reaching a hospital, compared with around 50 percent in Denver County, the state’s best-performing county.“We have way too many trauma centers along the front range of the mountains — we have too many in Fort Collins, too many in Denver, too many in Colorado Springs,” said Moore, who served as chief of trauma at Denver Health for nearly four decades.Governing, 3d ago

In 2021, SFARI launched the Autism Rat Models Consortium (ARC) RFA. Grants supported through this RFA use SFARI autism rat models to investigate the biology of autism risk genes, with a particular focus on complex behaviors and their underlying neural circuits. Although researchers have studied ASD risk genes in diverse experimental systems from fruit flies to mice, recent advances in gene editing technology have allowed for the manipulation of genes of interest in an increasing catalog of species. The SFARI rat models were generated at the Medical College of Wisconsin. These models and others are undergoing a behavioral phenotyping battery at the Simons Initiative for the Developing Brain (SIDB) at the University of Edinburgh.SFARI, 3d ago

In other words, without focusing on a whole human being, we miss opportunities to understand assets and resilience, which should be the foundation to promote optimal health throughout a lifetime.”...YES!

Newswise — FRANKFURT. Venoms have developed in many animal groups independently of each other. One group that has many venomous species is Hymenoptera, an insect order that also includes aculeates (stinging insects) such as bees, wasps and ants. Hymenoptera is very species-rich, with over 6,000 species of bees alone. And yet, despite the great ecological and economic importance of hymenopterans, very little is known about the evolutionary development of their venoms.By means of comparative genomics, researchers led by Dr. Björn von Reumont, who is currently a visiting scientist in the Applied Bioinformatics Working Group at the Institute for Cell Biology & Neuroscience of Goethe University Frankfurt, have now examined systematically and for the first time how the most important components of the venom of bees and other hymenopteran taxa developed in the course of evolution. The toxins are complex mixtures composed of small proteins (peptides) and a few large proteins and enzymes. Stinging insects actively inject this poisonous cocktail into their prey or attackers with the help of a special sting apparatus.In the first step, the researchers identified which of the peptides and proteins in the venom were most prevalent in hymenopterans. To do this, they drew on information from protein databases, although this was sparse. In addition, they analyzed the proteins in the venoms of two wild bee species – the violet carpenter bee (Xylocopa violacea) and the great-banded furrow-bee (Halictus scabiosae) – as well as of the honeybee (Apis mellifera). They found the same 12 “families” of peptides and proteins in all the hymenopteran venoms analyzed. These are evidently a “common ingredient” in these venom cocktails.In collaboration with colleagues from the Leibniz Institute for the Analysis of Biodiversity Change (LIB), the Technical University of Munich (TUM) and the LOEWE Center for Translational Biodiversity Genomics (LOEWE TBG), the research team then searched for the genes of these 12 peptide and protein families in the genome of 32 hymenopteran taxa, including sweat bees and stingless bees, but also wasps and ants such as the notorious fire ant (Solenopsis invicta). The differences in these genes, in some cases only the exchange of single letters of the genetic code, helped the scientists to determine the relationship between the genes of different species and later – with the help of artificial intelligence and machine learning – to compile a lineage of the venom genes.The surprising result was that many of the venom genes analyzed are present in all hymenopterans. Evidently the common ancestor of all hymenopteran taxa already possessed these genes. “This makes it highly probable that hymenopterans are venomous as an entire group,” concludes von Reumont. “For other groups, such as Toxicofera, which includes snakes, anguids (lizards) and iguania, science is still debating whether the venoms can be traced back to a common ancestor or whether they evolved separately.”Within Hymenoptera, only the stinging insects – bees, wasps and ants – have an actual stinger to administer the venom. The evolutionary old parasitic sawflies, by contrast, use their ovipositor along with their eggs to inject substances that alter their host plant’s physiology: The sirex wood wasp (Sirex noctilio), for example, not only introduces a fungus into the plant, which facilitates the colonization of the wood by its larvae, but also its own poisonous cocktail with the venom proteins examined in the study. The purpose of these proteins is to create suitable conditions in the plant for the larvae. “This means that the sirex wood wasp can also be classified as venomous,” says von Reumont.New venom components in bees are the gene for the peptide melittin and genes for representatives of the newly described protein family anthophilin-1. The fact that melittin is encoded by just one single gene came as a surprise to the researchers, as von Reumont explains: “Not only are there many different variants of melittin, but the peptide also accounts for up to 60 percent of the dry weight of bee venom. That is why science previously assumed that there must be many gene copies. We were able to disprove this quite clearly.” Because they found the melittin gene only in bees, the researchers also invalidated the hypothesis that it belongs to a group of venom genes postulated for stinging insects called aculeatoxins. Von Reumont is convinced: “This shows us once again that genome data are the only way to draw meaningful conclusions about the evolution of venom genes.”The Frankfurt study is the first one to show for an entire insect group with around one million species where venom genes originated and how they have developed. It provides a starting point for tracing the evolution of venom genes in the ancestors of Hymenoptera as well as specializations within the group. However, to be able to perform comparative genomics on a large scale, analysis methods for the partly very large protein families must first be automated.newswise.com, 4d ago
Newswise — TAMPA, Fla. — Melanoma is the deadliest form of skin cancer because of its ability to quickly grow and spread throughout the body. More than half of those with advanced melanoma will see the disease spread to the brain, where it rapidly progresses, often leading to death in only three to four months. Researchers in Moffitt Cancer Center’s Donald A. Adam Melanoma and Skin Cancer Center of Excellence have been working to better understand what drives melanoma brain metastasis. In a new study published in Nature Communications, they report on the identification of a cell signaling pathway that regulates the metastatic spread of melanoma cells to the brain.newswise.com, 4d ago
Newswise — Sharks, rays and skates are the ocean’s most threatened vertebrate group. Research led by the University of Zurich into their functional diversity has now revealed previously overlooked, critical conservation priorities, thereby underscoring the urgent need for targeted action to safeguard the threatened species.Biodiversity – the total variation of life – is multidimensional. Its study encompasses multiple facets, such as taxonomy (the variety of species), phylogenetics (their evolutionary history) and functionality (the ecological roles that species play in ecosystems). Protecting biodiversity implies safeguarding all of these dimensions.Now, an international team of researchers led by Professor Catalina Pimiento of the University of Zurich have unraveled the complex dimensions of elasmobranch biodiversity – the ocean’s most threatened vertebrate group, which includes sharks and rays. By contrasting functional diversity against other previously studied biodiversity facets – taxonomic and phylogenetic –, a new hierarchy of species and spatial conservation priorities emerged.Functional diversity changes the perspectiveThe researchers used an unprecedented global trait dataset to quantify global elasmobranch functional diversity, revealing a rich tapestry of varied ecological roles played by threatened species. “We identified the top endangered species crucial for maintaining the architecture of elasmobranch functional diversity, including the longfin mako shark, Ganges shark, daggernose shark, shortfin mako shark, and scalloped hammerhead shark,” explains Catalina Pimiento.Spatial analyses further showed that elasmobranch functional richness is concentrated along continental shelves and around oceanic islands, revealing 18 unique functional diversity hotspots that only marginally overlap with those of other biodiversity facets. “Many of the hotspots vital for elasmobranch biodiversity converge with fishing pressure along the coast of China, others fall around oceanic islands and high seas,” says Dr John Griffin of Swansea University, co-author of the study.Previously, two different biodiversity facets were used to identify conservation priorities – taxonomic and phylogenetic: the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species evaluates the urgency of a species’ extinction risk, and the EDGE of Existence program expanded this approach by also taking into account phylogenetic distinctiveness – whether or not species have long and unique evolutionary histories.Call to actionAlarmingly, the study finds that the multiple facets of elasmobranch biodiversity remain inadequately protected within the global Marine Protected Area network, leaving these species vulnerable to various threats. “Several global regions, including the coasts of China and Europe, that host hotspots of elasmobranch biodiversity face extreme threats from industrial fishing,” says Fabien Leprieur of the University of Montpellier, co-author of the study, further emphasizing the urgency of conservation efforts.The research underscores the need to integrate functional diversity into conservation strategies for elasmobranchs and other highly threatened species. As crucial components of marine ecosystems for millions of years, the preservation of elasmobranch biodiversity is paramount to ensuring the continued health of our oceans.newswise.com, 4d ago

Newswise — A new AI-assisted molecular diagnostic platform capable of identifying variants of COVID-19 and other infectious diseases has been developed by scientists in the UK. The low cost, portable device could play a crucial role in preventing future pandemics due to its accuracy and versatility.Scientists from the University of Surrey, Brunel University London, and Lancaster University in collaboration with the NHS, GB Electronics (UK) Ltd and Vidiia Ltd, have created the platform known as VIDIIA Hunter (VH6). It uses reverse transcription loop-mediated isothermal amplification (RT-LAMP) technology in combination with an artificial intelligence (AI)-based deep learning model. The AI model has been trained to read the results of tests identifying infectious diseases, including COVID-19 and removes users’ interpretation and errors whilst improving accuracy.Professor Roberto La Ragione, Professor of Veterinary Microbiology and Pathology at the University of Surrey, said:“Lateral flow tests are an efficient way of testing if you have COVID-19, however, there has always been a question mark over their accuracy which has only been heightened with the emerging number of variants now in circulation. As COVID-19 continues to evolve, we need to evolve with it and have highly accurate tests that can be readily used without the need for laboratory facilities.”To confirm the accuracy of VH6 scientists tested 150 COVI-19 positive clinical nasal swabs with a range of viral loads and 250 negative samples provided by NHS Berkshire, Surrey Pathology and Royal Lancaster Infirmary, Lancaster. The test was found to be highly accurate with a detection rate of 98 percent and a specificity of 100 percent. Additional testing found the device detected all the COVID-19 variants that have circulated in the UK since December 2020.Dr Aurore Poirier, first and co-corresponding author of the study and Research Fellow B at the University of Surrey, said:"The VH6 diagnostics platform has been approved for COVID-19 testing in the UK, but also has to potential to diagnose current and emerging infectious disease and antimicrobial resistance. Its portability, rapidity, accuracy, and affordability allow for near patient testing, in all laboratory and healthcare settings, including low-resources ones. The VIDIIA Hunter therefore has the potential to help control future outbreaks."To monitor and track the spread of COVID-19 and other infectious diseases, the test is connected to a smartphone app that allows an operator to manage and track the patients and samples. Results and graphs are displayed on the app in as little time as 20-30 minutes and automatically connects to a cloud. The platform allows near-patient testing and has the potential to detect other infectious diseases such as tuberculosis and dengue fever, and antimicrobial resistance.Unusually, the test can be used for human and animal healthcare which is a crucial step in identifying any future zoonotic diseases which could spread between the two.Professor Muhammad Munir, Professor of Virology and Viral Zoonosis at Lancaster University said,“Incorporation of LAMP technology with advanced modules of AI has empowered the earliest, reliable and economical detection of infections, including COVID-19, and holds potential for the detection of diseases in both humans and animals, making it a tool of significant medical importance.”The VH6 has now been approved for medical use in the United Kingdom under the UK Health Security Agency’s Medical Devices (Coronavirus Test Device Approvals, CTDA) Regulations 2022 and is CE-IVD marked and MHRA registered.A study using this diagnostic platform has been published in Frontiers in Molecular Biosciences.newswise.com, 4d ago
Newswise — Evidence from eastern Germany shows that early humans had a more varied diet than previously knownAround 400,000 years ago, early humans hunted beavers as a food resource and possibly also for their pelts. This is the conclusion of a team from Johannes Gutenberg University Mainz (JGU), the Leibniz Zentrum für Archäologie (LEIZA), also in Mainz, and Leiden University in the Netherlands. In their publication in the journal Scientific Reports, the authors show that Middle Pleistocene humans systematically fed on these smaller animals and hence had a more varied diet than thusfar known. Previously, the opinion was that that hominins of this age primarily subsisted on large mammals, such as bovids and rhinoceroses, for one simple reason: "The remains of large mammals from this period are generally much better preserved than those of small ones, not to mention plant remains," says Sabine Gaudzinski-Windheuser, Professor in the Department of Ancient Studies/Section Pre- and Protohistoric Archaeology at JGU and Director of the Archaeological Research Centre and Museum for Human Behavioural Evolution, MONREPOS, in Neuwied, which is part of LEIZA. She authored the new study together with two colleagues, Lutz Kindler, also from JGU and MONREPOS, and Wil Roebroeks from Leiden University. "Until now, cut marks on Palaeolithic beaver bones had been identified very rarely and on isolated bones only. Dietrich Mania's extensive and long-term excavations in Bilzingsleben yielded a large number of beaver remains. Their study has now revealed for the first time the long-term strategy behind the exploitation of these animals," she explains.Targeted hunting of young adultsThe researchers used magnifying glasses and digital microscopes to examine the approximately 400,000-year-old bones of at least 94 beavers, excavated several decades ago in Bilzingsleben, Thuringia. This enabled them to identify cut marks from stone tools that indicate intensive use of the carcasses. "It is interesting that the remains in Bilzingsleben mainly represent young adult beavers," says Gaudzinski-Windheuser. This indicates that hominins back then would have deliberately hunted inexperienced but fully grown and fat-rich animals. Fat was a very important food resource during the Pleistocene. "Until now, it was generally thought that people in Europe fed primarily on large game until around 50,000 years ago, and that this was an important difference to the more flexible dietary strategies of modern humans. We have now demonstrated that the hominin food spectrum was much broader much earlier," says Gaudzinski-Windheuser.newswise.com, 4d ago
The study uses a large and well-suited human dataset to investigate the relationship between brain microstructure, as determined by in vivo MRI, and obesity, as measured by waist-to-hip ratio, in humans. The authors identify two brain systems that are individually associated with two different markers of brain structure: Neurite density (ICVF) and free water (ISOVF), a potential indicator of inflammatory processes. The authors link the identified associations to biological processes and in particular to neurotransmitter systems using publicly available expression atlases. This is a definite strength as it paves the way to a deeper and mechanistic understanding of the observed associations. Finally, they use GWAS analyses to investigate the influence of genetic variation on the associations between brain microstructure and obesity. They find that only one of the associations is linked to genetic variation and conclude that the structural differences in the two brain systems could be interpreted as a cause or consequence of obesity, respectively.eLife, 4d ago

I hope everyone enjoyed the long weekend and short break! It is hard to believe that the semester is coming to a close. Each year, I rent a house on the Outer Banks of North Carolina to spend the break with my two sons. Sometimes, it’s just us. Other times, friends come along and fill the house. This year, it was just us. On one of the days, it rained – not in the way it rains in Colorado, but a 14-hour soaking rain. The day opened space to contemplate the future of public health how we make strides toward improving the health of our society.The COVID-19 pandemic was, and may continue as, one of the most substantial infectious disease threats in modern times that required an immediate public health response. However, the United States alongside other nations, was slow to provide widespread and convenient testing, distribute masks, and effectively communicate about safe practices and the changing scientific landscape. Nonetheless, the United States invested in new technology and developed an efficacious vaccine in record time. While its distribution, deployment, and uptake could have been improved, the scientific community achieved remarkable breakthroughs by sharing data and tissue samples at a pace not previously seen. Researchers openly collaborated at an international level. Meanwhile, the COVID-19 pandemic laid bare an inadequate public health infrastructure especially around inconsistent communication between federal, state, and local policies that prevented a cohesive response to the pandemic.What can we learn from the public-private partnerships that brought us exciting new treatments but also highlighted some of the shortcomings of public health? How can we use these lessons to reimagine the public health infrastructure? As the new dean of the Colorado School of Public Health, I’ve reflected at length as to why and how our nation rapidly responded to developing a new treatment, but large scale, transformational public health investments such as access to health care, new models of care delivery, and data integration across systems for policy development have been slower to come. In my first State of the School address, I suggested that public health, as a field and practice, is plagued by three myths that must be overcome. These myths are: public health isn’t sexy; public health isn’t a science; and public health is invisible until it fails.Myth #1: Public health isn’t sexy.As a society, we are drawn to new treatments and promises for a cure. The technology is exciting; the breakthroughs are breathtaking. What government or individual donor does not want to invest in an early-stage treatment that may cure or slow the progress of a disease that affects millions of people? The motivation for financial support is higher if this disease affects them or their loved ones. This enthusiasm remains high, almost without regard to a treatment’s chances of success, costs, and possible risk. How do we make the case for public health to be as equally exciting and breathtaking? Public health breakthroughs (e.g., clean water, sanitation practices, food inspection) have changed the course of history for civilization and have prevented countless deaths. Yet, the achievements of public health are not widely promoted as life-saving interventions. Public health interventions have a high chance of success, often come at low costs relative to the development of pharmaceutical interventions, and are generally associated with few downside risks. Tobacco companies made smoking sexy, a habit that is deadly, stinky, costly, and turns its users’ teeth yellow. Surely the case for public health’s ‘sex appeal’ is easier to make than the case made for tobacco products. We must be creative in how we change the narrative for public health.Myth #2: Public health isn’t a science.A quick google search defines science as “the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.” Public health professionals produce research that is grounded in theory, data driven, and evidence-based. Our papers are subject to rigorous review and our researchers compete for incredibly scarce resources—it is public health after all. Yet, the message of “science” often gets lost in the work we do and has even come under attack in recent years. “Science” is sometimes lost when we disseminate our evidence to colleagues in basic, translational, and clinical science who may not appreciate the complexity of our work. The average person understands that microbiology is a science but is unaware that public health research and practice is also a science and is guided by economic, social, and behavioral theories, among others.As a public health community, we must take responsibility for this perception and communicate more effectively about the thought and rigor that goes into what we do. Public health science uses data from complex tracking systems assembled for public health purposes, and often enhances those data with additional data that were assembled for other purposes but can inform our models and subsequent decisions. These data are stress tested with varying assumptions and sensitivity analyses and then frequently updated with new data. Furthermore, our scientists develop new methods to handle the ensuing complex analyses. Public health science exists at the intersections of human behavior, environmental forces, policy, society at large, and health. Therefore, our landscape is continually changing, and our scientists have to be nimble in response. A good example is how well our faculty worked together to produce evidence for Colorado’s governor to make data-driven and evidence-based decisions. We must do much more to educate everyone within and outside of our field about the science of public health and that our process is no different than basic, translational, and clinical science.Myth #3: Public health is invisible until it fails.Despite public health’s struggles with sex appeal and perceptions about its science, much of public health is “invisible” because it works so well. We take for granted that our food and drinking water are safe and that smoking is prohibited on airplanes. Most of us instinctively reach for the seatbelt when we settle into a car – all because of public health. However, when these measures were first introduced, they were met with resistance. We owe it to our field to point out the areas where public health continues to save lives. It is in these examples where we regain trust and convince the population, including policymakers, to adopt new measures that make our world a safer place where we can all thrive.How is public health not sexy when it saves so many lives? How is it not science when public health is theory grounded, data driven, and evidence-based? And how is public health invisible when there are so many examples of public health in action all around us, every day? Public health is visible, but it needs to be clearly understood.There are not enough resources in our society to treat each individual who has a health need. Because of this, societal level interventions are needed to make us safer, saner, and stronger. It is public health where such interventions are developed – and it is worthy of repeating that they are grounded in theory, data driven, and evidence-based, or simply put, science.cuanschutz.edu, 4d ago
The notion of LSCs has been invoked for a long time in the genetically defined and molecularly targeted paradigm of CML (Holyoake & Vetrie, 2017). Still these entities remain essentially peripheral to the disease management (Zhao & Deininger, 2021). We posit that the heterogeneity of LSCs is a barrier towards their efficient measurement and safe purging. Our high-resolution single cell multiomics maps suggest how to probe and deconstruct heterogeneity of CML, thereby permitting inference of leukemic vs. non-leukemic cells, estimation of BCR::ABL1+ LSCs, enumeration of their molecular features, and prospective isolation. Understanding how the cellular heterogeneity and plasticity emerges in the absence of extensive genetic variability would inform if the fully leukemogenic residual cells could either be safely eliminated pharmacologically or kept perpetually suppressed by empowered immune system to avoid recurrence (Hsieh et al., 2021; Zhao & Deininger, 2023). Alternatively, longitudinal sampling and sc-omics combined with barcoding may also reveal if the stem cell subpopulations and states are interconvertible (Lenaerts et al., 2010; Marjanovic et al., 2013), and therefore appear as potentially inexhaustible pool that can only be slowly eroded by several years of TKI treatment in a subset of patients. A more formidable barrier is the unstated but still presumed equivalence of immunophenotype and function. Rather than describing LSCs solely by surface markers, we propose that treating leukemic cellular clones as the fundamental units of selection and evolution during therapy would have a more meaningful impact in predicting response to existing therapy and switch to another TKI. The next line of advances will require assessing LSCs as pool of clones defined by their ability to contribute to primary and secondary resistance in patients on therapy, and recurrence in TFR without recourse to animal models.elifesciences.org, 4d ago
Although the team’s work represents the most comprehensive analysis of INPP5D in the AD brain, it remains to be determined whether INPP5D should be targeted with therapeutics. The team noted that their findings suggest INPP5D activity in AD brains is complex and future studies are needed to understand if INPP5D can be targeted to prevent cognitive decline in patients with AD. “A key question surrounds whether INPP5D is a feasible target for therapeutic development in AD,” they wrote. “Selective agonists and antagonists have been developed for INPP5D but the biology of INPP5D in the AD brain is complex and it is not immediately apparent whether INPP5D activity should be enhanced or inhibited for therapeutic benefit.”...GEN - Genetic Engineering and Biotechnology News, 4d ago

...(Copies from EA Forum for the benefit of lesswrongers following the discussion here)Definitely agree that empathy and other social feelings provide indirect evidence for self-awareness (ie, "modeling stuff about yourself" in your brain) in a way that optimism/pessimism or pain-avoidance doesn't. (Although wouldn't a sophisticated-enough RL circuit, interacting with other RL circuits in some kind of virtual evolutionary landscape, also develop social emotions like loyalty, empathy, etc? Even tiny mammals like mice/rats display sophisticated social behaviors...)I tend to assume that some kind of panpsychism is true, so you don't need extra "circuitry for experience" in order to turn visual-information-processing into an experience of vision. What would such extra circuitry even do, if not the visual information processing itself? (Seems like maybe you are a believer in what Daniel Dennet calls the "fallacy of the second transduction"?)Consequently, I think it's likely that even simple "RL algorithms" might have a very limited, very shallow, non-self-aware kinds of experience: an image-classifier is doing visual-information-processing, so it probably also produces isolated "experiences of vision"! But of course it would not have any awareness of itself as being a thing-that-sees, nor would those isolated experiences of vision be necessarily tied together into a coherent visual field, etc.So, I tend to think that fish and other primitive creatures probably have "qualia", including something like a subjective experience of suffering, but that they probably lack any sophisticated self-awareness / self-model, so it's kind of just "suffering happening nowhere" or "an experience of suffering not connected to anything else" -- the fish doesn't know it's a fish, doesn't know that it's suffering, etc, the fish is just generating some simple qualia that don't really refer to anything or tie into a larger system. Whether you call such a disconnected & shallow experience "real qualia" or "real suffering" is a question of definitions.I think this personal view of mine is fairly similar to Eliezer's from the Sequences: there are no "zombies" (among humans or animals), there is no "second transduction" from neuron activity into a mythical medium-of-consciousness (no "extra circuitry for experience" needed), rather the information-processing itself somehow directly produces (or is equivalent to, or etc) the qualia. So, animals and even simpler systems probably have qualia in some sense. But since animals aren't self-aware (and/or have less self-awareness than humans), their qualia don't matter (and/or matter less than humans' qualia)....Anyways, I think our core disagreement is that you seem to be equating "has a self-model" with "has qualia", versus I think maybe qualia can and do exist even in very simple systems that lack a self-model. But I still think that having a self-model is morally important (atomic units of "suffering" that are just floating in some kind of void, unconnected to a complex experience of selfhood, seem of questionable moral relevance to me), so we end up having similar opinions about how it's probably fine to eat fish.I guess what I am objecting to is that you are acting like these philosophical problems of qualia / consciousness / etc are solved and other people are making an obvious mistake. I agree that I see a lot of people being confused and making mistakes, but I don't think the problems are solved!...lesswrong.com, 20d ago
Consider this description of America's discontent:"...a Hamlet-like loss of self-confidence, with an apocalyptic sense of doom for the civilization. On the Right it embodies a conviction that the sensate culture is pushing the society down the Gaderene slope of drugs-and-fornication to destruction. On the Left there is the vague sense that America is imperialist, fascist-oriented, caught in inner contradictions of class and ethnic struggles which will end in self-destructive wars or civil chaos....the fragmenting and polarizing of institutions (family, neighborhood, university, church, nation)--in short, the overloading of the social nervous system by sudden accelerations of change."Is that a reasonably fair description of America in 2023? Interestingly, it was written in January 1974, describing the America of 50 years ago. (America Agonistes (Max Lerner, Foreign Affairs, January 1974). I have often referred to Peter Turchin's evidence-based cyclical mapping of the structural sources of social disorder which he has updated in his latest work, End Times: Elites, Counter-Elites, and the Path of Political Disintegration.Turchin identified 50-year cycles of integration--in which people find reasons to cooperate--and disintegration, in which people find reasons to devolve cooperation. From this perspective, that an article from 50 years ago sounds current is not only no surprise, it was easily predictable.This Salon article summarizes many of the conclusions in Turchin's new book: Hope in "End Times": Peter Turchin's analysis of our coming collapse could help us avoid it:For all its breadth and depth, there's a simple message at the core of "End Times": At the heart of our problems, Turchin writes, is "a perverse 'wealth pump' ... taking from the poor and giving to the rich," and we have to find a way to turn it off.This reflects "one of the most fundamental principles in sociology, the 'iron law of oligarchy,'" he writes, "which states that when an interest group acquires a lot of power, it inevitably starts using that power in self-interested ways." For example, while wages fell far behind the growth of economic productivity from 1979 onward, Turchin cites analysis from the Economic Policy Institute indicating that three-fourths of that gap was due to elite-driven policy shifts: weakened labor standards, the erosion of collective bargaining, corporate globalization and so-called fiscal austerity.Diminished economic conditions for the less educated were accompanied by a decline in the social institutions that nurtured their social life and cooperation. These institutions include the family, the church, the labor union, the public schools and their parent-teacher associations, and various voluntary neighborhood associations."Back in America's previous cyclical crisis, Lerner identified the sources of decline in this way: "Civilizations die not only of rigidity, failure to meet challenges, constitutional breakdown. They may also die of deep alienations and the erosion of crucial institutions."He concluded that America's cult of change precluded a decline due to rigidity:"My own stress is on studying the crucial factors in the death of past civilizations, and using them to put questions concerning American directions. To start with, the rigidity which marked a number of declines and falls is only minimally present in America, with her cult of change and her experience of social and cultural revolution."I will consider the issue of rigidity in upcoming posts, but for now, let's consider the decay of America's social and economic foundations, starting with Turchin's perverse wealth pump that has stripmined the bottom 90% to enrich the top 1%, as shown in this chart:...substack.com, 21d ago
In terms of narrative, unlike long-form dramas, which feature progressive and interlocking complex narratives and logical reasoning, micro-short dramas are known for their strong plots, fast pace, and small incisions. Creators can organically combine scientific imagination with more mature film and television genres such as suspense, romance, comedy, and action. Based on scientific concepts and realistic logic, they can increase dramatic tension and emotional power through clever plot settings and atmosphere creation. , giving the audience a novel and unique viewing experience. For example, a micro-short drama allows one actor to play multiple roles, telling the story of several characters who look alike but have completely different destinies. Because of a mysterious social software, they are involved in a bizarre virtual world, and they continue to peel off the cocoons to explore the truth and finally solve the mystery. The story has a lot of twists and turns and a suspenseful atmosphere, which is in line with the “Z generation”‘s pursuit of exciting and brain-burning viewing appeals.Archyde, 5d ago
As a philosopher, I'm not opposed to abstract theorizing. However, it's crucial to distinguish the scientific questions of consciousness from the philosophical questions. The scientific task is to work out which kinds of brain activity correspond to consciousness, and it's this task that detailed neurophysiological investigations — equipped to catch the HERE IT IS marker of consciousness — will help us make progress on. But what we ultimately want from a theory of consciousness is an explanation of why brain activity — of whatever form — is correlated with consciousness in the first place. Because consciousness is not an observable phenomenon, the "why" question is not one we can make progress on with experiments. In Why? I develop a radical form of panpsychism — the view that consciousness goes right down to the fundamental building blocks of reality — aimed at addressing the philosophical challenges of consciousness, as well as providing a framework for scientists to make progress on the scientific issues.livescience.com, 23d ago

Another consequence of an over-emphasis on maps with sharp borders is the wrongful interpretation of their expansion into adjacent areas as evidence for reorganisation. This is often described as ‘remapping’, ‘remodelling’, ‘expansion’, ‘rewiring’, ‘take-over’, ‘invasion’, ‘reoccupation’, and even ‘capture’ (Merzenich et al., 1983a; Merzenich et al., 1983b). As we discuss throughout the piece, it is essential that we do not turn the result of a mode of analysis – remapping – into a true phenomenon (reorganisation). Instead, as we have seen, a change to map boundaries can be the consequence of learning-related strengthening of pre-existing dedicated architecture. More importantly, this ‘remapping’, regardless of the neural process it reflects, is often not causally related to behavioural recovery at all. Thus, de-emphasising brain maps with sharp borders can lead the field away from positing a special form of plasticity predicated on qualitative changes in the computational capacity of an area. Instead, a given brain area may have the capacity to receive information from more diverse sources than is suggested from the derivation of discrete maps. How these more diverse inputs are processed will of course be constrained by the brain area’s local and global connectivity. This connectivity fingerprint pre-determines to a large degree what the local computational capacities of a given brain area are, and how these computations are read out by downstream areas to inform behaviour. Even when inputs are engineered by scientists and detoured into a different brain area, as discussed in the section ‘Experimentally induced rewiring of retinal input in newborn ferrets’, successful processing of this rewired input depends on the recipient architecture already being compatible with the novel input.eLife, 13d ago

These trials focus on its effectiveness against respiratory tract inflammation from the influenza virus. This news marks a significant milestone for the Vietnamese medical sector, especially in setting a trend in global research and application of spore probiotics for respiratory well-being. Using a nasal spray with Bacillus probiotics in treating influenza patients has significantly reduced the total treatment time by up to 60 per cent (from five days for the control group to just two days for the spore probiotics spray group). Additionally, it increased treatment efficacy by 58 per cent, aiding in the complete recovery from symptoms such as runny nose, fever, sneezing, cough, rapid heartbeat, and rapid breathing. The decline in clinical symptoms corresponds with a drop in both viral and bacterial counts, notably decreasing by approximately 400 and 1,000 times on the second treatment day compared to the initial day of hospitalisation. The clinical trials confirm that the nasal spray containing Bacillus probiotics reduces treatment duration, lowering the chances of bacterial infection or severe respiratory tract complications. This not only helps cut treatment costs but also reduces antibiotic consumption for infections, fostering improved patient health. This positive signal is crucial for the medical community as it contributes to easing the burden on hospitals during disease outbreaks. Furthermore, the clinical trials indicate that the Bacillus probiotics, when formulated as a spray, offer superior effectiveness through interaction with the mucosal immune system of the nasal cavity. This means that the spore probiotics nasal spray not only supports the treatment of influenza-infected patients but also aids in treating respiratory tract inflammation caused by other viruses such as RSV, adenovirus, rhinovirus, coronavirus, etc. Regular use of Bacillus probiotics spray proves beneficial in enhancing the respiratory barrier, thereby boosting the effectiveness of virus-prevention vaccines. Probiotics, also known as a type of medicinal probiotics, serve as an effective solution in alleviating symptoms of respiratory diseases. In a previous study published in the Scientific Reports - Nature journal in July 2022, LiveSpo Navax supported the treatment of respiratory syncytial virus (RSV) in children. It significantly reduced the treatment time by more than one day and lowered the RSV concentration by over 600 times, surpassing the effectiveness of using physiological saline. This scientific research ranked among the top 100 downloaded microbiology articles in 2022 in the Nature Journal, demonstrating the widespread interest from scientists and readers worldwide and contributing significant values to the community. The two internationally validated clinical studies have confirmed that the LiveSpo Navax nasal spray, containing Bacillus probiotics, has demonstrated no side effects, guaranteeing complete safety for children. All patients using LiveSpo Navax in conjunction with standard treatment medications showed no signs of local bacterial infection or any digestive issues like vomiting, diarrhoea, or other abnormal symptoms. Therefore, in the future, this product will be fully suitable for inclusion in treatment plans for patients infected with respiratory viruses or bacteria. Dr. Nguyen Hoa Anh, Director of the Spore Probiotics Research Center shared: "We are proud to offer an effective support solution for patients with respiratory infections caused by viruses, bacteria, or acute inflammation. Moving forward, we will continue to research, develop, and bring the LiveSpo Navax product to consumers in Viet Nam and globally." With groundbreaking technology in spore probiotics - medicinal probiotics, LiveSpo Pharma aims to build a future free of antibiotics for everyone. Dang Quoc Hung, CEO of LiveSpo Pharma, stated: "At LiveSpo, we always strive to deliver the best products to our customers and the community. With the expertise of our scientific team, who have achieved notable research milestones in microbiology domestically and internationally, we are confident in developing and manufacturing effective and convenient spore probiotic products without side effects. This effort contributes to reducing antibiotic use and minimising antibiotic resistance in Viet Nam and the world. This is also LiveSpo's mission for development." As confirmed by the two successful publications in the prestigious Scientific Reports - Nature journal, LiveSpo has asserted its breakthrough in the products resulting from the company's extensive research and development efforts. LiveSpo takes pride in introducing Viet Nam's spore probiotics technology to the markets of developed countries which spearhead global medical advancements. This groundwork sets the stage for the future growth of Vietnamese enterprises, emphasising the expansion into global markets and the international promotion of Vietnamese brands and products. With a focus on product development, LiveSpo aims to create value for the community. The company's successful development of the Bacillus probiotics spray, which effectively aids respiratory disease treatment and minimises the risk of severe inflammation and prolonged antibiotic use, is helping pave the way toward a future less reliant on antibiotics. With its nature as a type of medical probiotic, LiveSpo products will help strengthen the natural immune barrier for the body when used over an extended period, thereby contributing to a community immune system if widely applied. This serves as a natural shield, protecting the community from diseases caused by viruses and bacteria. Hashtag: #Livespo...SME Business Daily Media, 4d ago

The new focus on contraceptive care, Moore said, is about investing in health care for women and girls “before abortion even needs to be an option.”The governor referred to data compiled by the nonprofit organization Power to Decide that shows about 285,000 women in Maryland live in “contraceptive deserts” — areas where the number of health centers offering a full range of contraceptive services is not enough to meet the needs of women who rely on publicly funded contraception.Maryland also has one of the highest rates of pregnancies that are unwanted or wanted later, according to a 2017 Guttmacher Institute study that found 44 percent of pregnancies in the state fit that category. That was tied with New York and New Jersey for the highest, the study found.The partnership announced Tuesday is between Upstream USA, a national nonprofit working to reduce unplanned pregnancies, and CCI Health Services, a nonprofit federally qualified health center that operates in Prince George’s and Montgomery counties.The nonprofit’s staff will train and provide technical assistance to primary care providers who aren’t fully equipped to handle patients’ contraceptive needs. Maryland law requires most contraceptive care to be offered for free, and officials said Tuesday the care offered through the partnership would not be charged to patients.Training will include instructions as straightforward as making sure providers know to ask questions like, “Do you plan to become pregnant in the next year?” and then, if the answer is no, to offer a full range of options, said Upstream USA CEO Mark Edwards.Depending on the provider, those options may currently be limited. For example, a primary care doctor may only have immediate access to prescribe oral contraceptive pills, but if the patient wants something like an intrauterine device (IUD), they may have to travel to a family planning center, which could be more inaccessible, said Maryland Health Secretary Laura Herrera Scott.Offering those options where people are, Herrera Scott and others said, is a more equitable solution.“We see integrated contraceptive conversations in the fabric of all of our business as a vital step toward achieving equity,” said Dr. Sonya Bruton, CEO and president of CCI Health Services.Bruton said CCI serves about 65,000 patients in Montgomery and Prince George’s counties, two of the most diverse counties in the state.The centers have been offering contraceptive services for 14 years under Title X, a federal program that provides family planning for people with lower incomes. But coordinating with Upstream will help to “more seamlessly integrate family planning at every touchpoint,” Bruton said alongside the governor and other officials.From educating the person at the front desk on how to have a conversation with a patient, to filling the knowledge gaps for clinicians who might not know all of the contraceptive options, the training has already helped CCI with a new “systemwide” approach, she said in an interview.“Is it rocket science? No. Is it even hard? No. But when you’ve got a busy practice that’s dealing with a million things — and for us with populations that have needs that go well beyond even health — it’s the difference between having an effective conversation that meets the needs and allows them to have a little bit more choice about what happens in their life, or not,” Bruton said.No state funding is going toward the collaboration and Upstream is not seeking public investment, Edwards said in an interview. He described the state’s involvement as critical in setting up the connection earlier this year when Upstream began working with CCI.The state’s role in connecting the nonprofit with other community health centers beyond CCI, and potentially larger health systems and hospitals, will also be important as it plans to expand the work across the state, said Upstream Vice President Seville Meli.Meli and others involved did not specify where in Maryland the contraception deserts have the most severe impact or which areas might be targeted for future collaborations.“It will take time to roll this out. We’ll do it incrementally and we’ll really try to have a broad impact,” said Meli, noting it takes 12 to 15 months of training for each individual health center.State Sen. Ariana Kelly, a Montgomery County Democrat who sponsored the law that required insurance plans to cover most contraceptive care for free starting in 2018, said she was excited about the collaboration as a way of actually getting contraceptives to the areas where they’re needed.“This partnership is the next step,” Kelly said. “The cost is not a barrier. But … if you’re going to a regular primary care provider, are they going to be able to provide you with the multiple different methods that we already required under Maryland law with no cost sharing?”Kelly, who has also helped pass several bills expanding abortion access, said she’s introducing legislation in the annual 90-day session that begins in January to require community colleges to offer 24-hour access to contraception. Without larger health services on those campuses, the care could come in the form of vending machines that offer condoms or even the Opill, which the FDA recently approved as the first over-the-counter birth control pill.“There’s a really cool emergence in innovative contraceptive methods and delivery mechanisms that we’re seeing,” Kelly said.©2023 Baltimore Sun.

...claims aren't actually science itself. When your only method is to ask people what products they use, if they feel sad, angry, or have a disease, and then correlating the product you wanted to target to the malady, it is easy to understand why during COVID-19 disease epidemiologists had a difficult time getting traction - they had never stood up to the cranks at Harvard School of Public Health and National Institute of Environmental Health Sciences using food surveys to try and scare people about everything.Epidemiology is the basis for a new exploratory paper which claims that siloxanes, which help to create shiny, smooth hair, are increased if you straighten or curl your hair, and that might have health implications.Scared of this image? I can narrow the list of media corporations you read, I can hone in on your food preferences, and certainly how you vote. The experiment is fine for what it is. They set up a tiny house and had people style their hair while they measured cyclic volatile methyl siloxanes using mass spectrometry. Unsurprisingly, they increased. Higher temperatures caused higher amounts, as did more hair. So cut your hair short and don't curl it? Or...what? If I tell you your chances of winning the lottery are 1 in 235,000,000 but if you give me money it will drop to 1 in 234,000,000, you aren't giving me money.Yet if I claim that spending more for a product that does not contain something will increase your chances of not getting a disease, with no relative risk included, a whole lot of people who buy organic food, supplements, and alternatives to medicine will spend more. In the case of California, the government will force poor people to spend more, with no health or environmental benefit.The presence of a pathogen does not mean pathology, except on an IARC Working Group where they exist to scare everyone about everything. In the real world, of science and natural laws, the dose makes the poison. The volatile organic compounds they're detecting in higher quantity still can't harm you unless are are styling your hair 140 times per day for 300 years. And are a rat.The authors are so intent on scaring the public they say you can't even open a window, because then you are releasing it into the atmosphere where it does...what? Decamethylcyclopentasiloxane(D5) they cite specifically doesn't do much at all and is gone in 5 or 6 days, unless the whole planet spends all their days - wait, nights, because nature makes it nearly 300 percent more prevalent at night - heating up their hair.This will be fodder for the activists who are against cosmetics but isn't really informing the public about hazard or risk. It is just suggesting a potential hazard in rats in any amount is risky. That's a way to troll for an expert witness contract from a trial lawyer, not science.Science 2.0, 4d ago
TAMPA, Fla. — Melanoma is the deadliest form of skin cancer because of its ability to quickly grow and spread throughout the body. More than half of those with advanced melanoma will see the disease spread to the brain, where it rapidly progresses, often leading to death in only three to four months. Researchers in Moffitt Cancer Center’s Donald A. Adam Melanoma and Skin Cancer Center of Excellence have been working to better understand what drives melanoma brain metastasis. In a new study published in Nature Communications, they report on the identification of a cell signaling pathway that regulates the metastatic spread of melanoma cells to the brain.SCIENMAG: Latest Science and Health News, 5d ago

For over two decades there has been a growing interest and activity to explore the use of Virtual Reality (VR) and robots in rehabilitation and clinical (surgical) training. In rehabilitation, the model is to incorporate robotic assistance designed to enhance recovery following injury. In this model it is expected that the robotic system will be made available possibly during the patient’s hospital stay or in the months that follow. In surgical training, the model is to optimise personalised clinical procedures by facilitating co-development of new surgical techniques and the tailoring of difficult patient-specific interventions. Today VR technology is applied to advanced fields of medicine, engineering, education, design, training, and entertainment. VR uses computer interfaces to mimic real world beyond the flat monitor to give immersive 3D (Three Dimensional) visual experiences. Often it is hard to reconstruct the scales and distances between objects in static 2D images. Thus, the third dimension helps bringing depth to objects. In this talk will look at new ways of using VR and Robots through a gamification paradigm for clinical training and will demonstrate how strategies that aim to ‘trick’ the brain can have a positive impact on the recovery of cognitive and physical injuries and in reducing pain.UCL Faculty of Medical Sciences, 18d ago
Computer models of the individual components of the peripheral auditory system – the outer, middle, and inner ears and the auditory nerve – have been developed in the past, with varying level of detail, breadth, and faithfulness of the underlying parameters. Building on previous work, we advance the modeling of the ear by presenting a complete, physiologically justified, bottom-up computer model based on up-to-date experimental data that integrates all of these parts together seamlessly. The detailed bottom-up design of the present model allows for the investigation of partial hearing mechanisms and their defects, including genetic, molecular, and microscopic factors. Also, thanks to the completeness of the model, one can study microscopic effects in the context of their implications on hearing as a whole, enabling the correlation with neural recordings and non-invasive psychoacoustic methods. Such a model is instrumental for advancing quantitative understanding of the mechanism of hearing, for investigating various forms of hearing impairment, as well as for devising next generation hearing aids and cochlear implants.interestingengineering.com, 7d ago
Fitzgerald has nothing against nature — he enjoys a trek in the wilderness about as much as anyone. He just believes that it is not a panacea for the most serious problems that the modern city encounters. “From the most avant-garde science fiction to the most banal planning documents,” he writes, “a shared agenda has emerged: for the good of humanity, the future of the city must be woody and green. … It’s as if, all of a sudden, there is no problem of the built or physical or social environment that cannot be fixed by leaning into a sturdy yew or beech.” In Fitzgerald’s view, this is a fantasy without hard evidence to back it up.THE NOTION THAT CITIES ARE INEVITABLY CHAOTIC, STRESSFUL PLACES goes back to the early years of the American republic, to Thomas Jefferson and Henry David Thoreau, and to Frederick Law Olmsted, who in the mid-1800s designed Manhattan’s Central Park as a green refuge where overburdened, overstressed urban workers could escape for refreshment and renewal.Urban disrespect reached a sort of peak in the 1920s. The prominent financier Simon Straus declared that “in our great cities, people break down in health or reach premature senility because of late hours, loss of sleep, fast pleasures, and headlong, nerve-racking methods of existence.” A popular advertisement portrayed urban life as “24 hours of noisy crowded streets. Of dust and gas-ridden air. Of machine-made speed. Of strain. Of nervous tension.”But the urban pessimism that Fitzgerald chronicles is largely a product of the 1970s, when big cities were in the midst of a crisis of rising crime, dirty streets and annoying congestion. Neuroscientists began connecting crowded cities to actual human depression and anxiety. They are still doing it. “Today,” Fitzgerald writes, “a lot of urban thinking derives from this notion that the city is a space that produces mental illness, not only because of its hectic or worrisome social life but because of its actual physical structure.”A study conducted in Mannheim, Germany, for example, concluded that growing up in an urban environment changes the human brain, generating fearfulness in the stress-driven amygdala and areas of the cerebral cortex. Research from the city of Aarhus, in Denmark, found that the more vegetation one experiences as a child, the smaller the risk of mental problems in adulthood. And a study at Stanford University reported that excessive walking in a crowded urban corridor increases dangerous rumination and activates a part of the brain linked to emotional problems.The conclusions drawn from these studies have led to a neurological idea called “attention restoration theory,” which posits, essentially, that simply looking upon nature boosts human concentration powers in a positive way.IT’S QUITE A MOUND OF DATA. How seriously should we take it? Fitzgerald believes that there is a placebo effect at work here, that we are told so often as young people that nature gives us a lasting sense of well-being that we are programmed to tell researchers that it does that. In truth, placebos aren’t worthless. If we are trained to believe that cities make us depressed but that nature makes us permanently and biologically happy, and we continue to feel that way, perhaps something good has been accomplished.But are these feelings permanent or transitory? I am no scientist, but I live across the street from a very nice park, and I walk through it a couple of times a week. It’s a pleasant experience. Does it make me a happier person over a significant length of time? I have trouble accepting that notion, as does Fitzgerald. “We’re overinvesting in nature,” he writes, “as a panacea for what are actually fairly mundane urban problems — that we have mistaken what is really … a sideshow to the wider sense of melancholy that has often accompanied the modern world.”If cities were as toxic as much of modern neuroscience is telling us, then we ought to be seeing some bad numbers in our biggest places. But they are not that easy to find. The opioid addiction crisis is a more serious problem in many depressed small towns than it is in the largest cities. In 2019, just before the COVID-19 pandemic reached us, life expectancy in New York City was 82.6 years, compared to the national average of 78.9. Once COVID-19 took hold, rural residents were more than 35 percent more likely than urban residents to die within 90 days after hospitalization for the virus. Urban death rates were higher for minorities and lower-income people, but this, however regrettable, is a different issue.Moreover, as Fitzgerald argues, to portray cities as totally deprived of greenery is a bit of an overstatement. “The truth,” he writes, “is that urban spaces are festooned with vegetation. Wanted and unwanted, useful and annoying, pretty and ugly. Once you start looking there’s green stuff everywhere in cities.”IN ANY CASE, THERE IS NO SIGN the urban greenery onslaught is slowing down, in the United States or overseas. New York’s Nature Conservancy wants to classify the city’s 7 million trees as a single forest system, “to sustain New York City for decades to come.” Madrid has plans to construct a “green wall” around the city featuring 500,000 new trees. And perhaps most consequentially, Paris Mayor Anne Hidalgo has declared her intention to make half the city’s surface area “vegetative” by the year 2050.Fitzgerald seems rather dismissive of these efforts. I wouldn’t go that far. I think a major tree-planting campaign in Paris would add to the iconic beauty the city has long possessed. What I agree with is his skepticism that thousands of acres of new vegetation would make the inhabitants permanently calmer, saner or healthier. “I just wasn’t at all convinced,” Fitzgerald explains, “that the simple presence of grass and trees could truly have what sounds like, in all truth, a quasi-religious, even transcendental effect on nearby humans.”Fitzgerald’s amiable contrarianism will earn him his fair share of detractors, but that is what Jane Jacobs faced when she blew the whistle on city planners in the 1960s. In challenging the conventional wisdom of nature-based urban panaceas, while confessing to his “resolutely affirmative view of city life,” Fitzgerald has placed himself quite firmly in the Jacobs tradition.Governing, 14d ago
