Can adults still grow new neurons in their brains? You'd think we might know the answer to the question of adult “neurogenesis” after more than half a century of neuroscience research. But it turns out we don't.In this episode of The Studies Show, Tom and Stuart look into the suprisingly controversial question of adult neurogenesis. Are you “stuck with” the number of brain cells you had as a child, or can you add to that number by making the right choices as an adult? And does it even matter?This podcast is brought to you by Works in Progress magazine, which this week has a new article explaining why nuclear power is so expensive (spoiler: it relies on an incorrect scientific model that we've discussed in previous podcast episodes: the “linear no threshold” model.

De matière miracle à ennemi publique numéro 1, le plastique s'infiltre partout : y compris dans les grands titres d'actualité. “52 000 microparticules de plastique par an ingéré par notre corps selon une étude canadienne” lisait-on en juin 2019. “Du plastiques présents partout… jusque dans les fœtus humains” titrait Courrier International en 2024. Une pollution qui s'immisce au plus profond de nous et de notre environnement sans que l'on sache forcément remonter à la source de la contamination. Parfois, les réponses les plus prometteuses semble les plus incongrues. Et si nous regardions par exemple du côté… de nos pneus ? En plateau avec nous aujourd'hui pour parler de la pollution microplastique en ville, nous recevons : Louisa Landebrit, doctorante, et Tiago De Oliveira, post-doctorant, au Laboratoire Eau et Environnement de l'Université Gustave Eiffel sur le site de Nantes. Cette émission est en partenariat avec le Muséum d'histoire naturelle de Nantes, et leur cycle de conférences “Sciences Eton'Nantes”. Elle a été préparée, animée et réalisée par Sophie Podevin.

En este capítulo, exploramos cómo la radiación ultravioleta en Marte, hasta ahora estimada solo mediante modelos teóricos, ha sido finalmente medida desde la superficie gracias al instrumento REMS, a bordo del rover Curiosity. Los resultados revelan que, aunque intensa, esta radiación no es tan letal como se creía: presenta variaciones bruscas y niveles comparables a los de la Tierra primitiva, cuando surgió la vida. El hallazgo, publicado en PNAS, tiene implicaciones clave para la astrobiología y la protección planetaria, especialmente ante futuras misiones humanas. Nos lo cuenta uno de los autores del estudio, Daniel Viúdez-Moreira, investigador del Centro de Astrobiología (CAB, CSIC-INTA).

In studio Luca e Leonardo di parlano di due argomenti di ricerca molto applicata. Nella prima parte Luca parla di un articolo uscito sulla rivista PNAS che descrive come si possa riuscire a pulire un catetere aggiungendo delle ciglia al suo interno e facendole vibrare con un ecografo, per generare un flusso che rimove impuritá e germi. Leonardo descrive come funziona un'organizzazione che sfrutta i RansomWare, dei software che servono a bloccare un sistema in produzione, per poi chiedere un riscatto alla vittima in cambio di riattivare il server. Nel mezzo, Giuliano intervista Luigi Buononato e Francesco Molinari due studenti del liceo Scientifico Martin Luther King di Genova per raccontare la loro esperienza, unica in italia, che ha riguardato la replica di un esperimento da nobel di fisica quantistica in una scuola.Cateteri con le ciglia: https://www.pnas.org/doi/10.1073/pnas.2418938122Ransomware: https://cacm.acm.org/research/ransomware-extortion-is-my-business/Un simpatico archivio che raccoglie chat tra gli estortori e le vittime: https://github.com/Casualtek/Ransomchats/blob/main/Conti/20210812.jsonDiventa un supporter di questo podcast: https://www.spreaker.com/podcast/scientificast-la-scienza-come-non-l-hai-mai-sentita--1762253/support.

How do monsoons really work? What makes them plentiful some years, but vanish completely in others, causing drought-like conditions? Climate scientists have been seeking answers to these questions for a long time. Now a research paper has come up with an intriguing explanatory concept: atmospheric memory. The study was conducted by two scientists -- Anja Katzenberger & Anders Levermann -- from the Potsdam Institute for Climate Impact Research (PIK). Titled ‘Monsoon Hysteresis reveals Atmospheric Memory', it was published recently in the scientific journal PNAS. The study showed, for the first time, that the atmosphere can store moisture over extended periods, creating a physical memory effect. In other words, the atmosphere can ‘remember' its previous state by storing physical information in the form of water vapour.” The paper also talks about how there is a tipping point in the system that determines monsoon rainfall. So, how does this discovery change our understanding of how monsoons work? What are its practical applications? What are the risks posed to this system by things like pollution and global warming? Guest: Anders Levermann, Professor of the Dynamics of the Climate System at the Institute for Physics and Astrophysics of the Potsdam University, Germany. Host: G. Sampath, Social Affairs Editor, The Hindu. Edited by Sharmada Venkatasubramanian. Learn more about your ad choices. Visit megaphone.fm/adchoices

Episode Summary: Join host Chris Clarke in this thought-provoking episode of "90 Miles from Needles" as he delves into the crucial humanitarian efforts of Laurie Cantillo and Humane Borders. As the border challenges unfold, Laurie discusses her organization's mission to provide life-saving water stations in the desert for migrants facing extreme peril during their journey to the United States. This episode sheds light on the often-misunderstood realities of border crossings and the humanitarian responses necessary to combat these challenges. Through vibrant storytelling, Laurie Cantillo and Chris Clarke engage in a candid discussion about the evolving landscape of the U.S.-Mexico border, addressing widespread misconceptions and the dire need for compassion and accurate representation of migrants. The conversation highlights the devastating impact of border policies and the unyielding resolve of those risking their lives for a chance at a better future. With insights into borderland human rights, as well as environmental concerns caused by border militarization, this episode offers an in-depth exploration of the human and ecological costs associated with the border crisis. Key Takeaways: Humane Borders provides life-saving water stations across the Sonoran Desert to support migrants, hikers, and even wildlife, confronting the severe drought conditions and inhumane border policies. Contrary to this administration's narrative, migrants crossing the desert to seek asylum are not an "invasion," but rather families and individuals fleeing violence and economic instability. The concept of "prevention through deterrence" initiated by the U.S. government did not deter crossings but instead caused thousands of migrant deaths since its implementation. Laurie emphasizes the stark reality that many Americans are misinformed about migrant communities, which are less prone to crime and more likely to contribute positively to society. Initiatives like Humane Borders represent nonpartisan, humanitarian efforts focused on human dignity and environmental responsibility amidst geopolitical complexities at the border. Notable Quotes: “We're all human. We all need water.” - Laurie Cantillo “The government knew at the time that people would die, but did not expect it to occur at the scale that's happening.” - Laurie Cantillo “I would much rather have as my neighbor someone who would cross the desert to become a U.S. citizen than someone who just wants to slam the door shut on people in need.” - Laurie Cantillo “The only fear I ever have at the border is from far right militia and vigilante groups.” - Laurie Cantillo “The wall will fall down of its own accord. Probably before I do.” - Chris Clarke Resources: Humane Borders Website: humaneborders.orgHumane Borders' mortality map: https://humaneborders.info/app/map.asp Border Angels: Organization mentioned that helps families find missing loved ones.

This week on the show: Are we ready to create digital models of the human brain? Last month, Stanford researcher Andreas Tolias and colleagues created a "digital twin" of the mouse visual cortex. The researchers used the same foundation model approach that powers ChatGPT, but instead of training the model on text, the team trained in on brain activity recorded while mice watched action movies. The result? A digital model that can predict how neurons would respond to entirely new visual inputs. This landmark study is a preview of the unprecedented research possibilities made possible by foundation models of the brain—models which replicate the fundamental algorithms of brain activity, but can be studied with complete control and replicated across hundreds of laboratories.But it raises a profound question: Are we ready to create digital models of the human brain? This week we talk with Wu Tsai Neuro Faculty Scholar Dan Yamins, who has been exploring just this question with a broad range of Stanford colleagues and collaborators. We talk about what such human brain simulations might look like, how they would work, and what they might teach us about the fundamental algorithms of perception and cognition.Learn moreAI models of the brain could serve as 'digital twins' in research (Stanford Medicine, 2025)An Advance in Brain Research That Was Once Considered Impossible (New York Times, 2025)The co-evolution of neuroscience and AI (Wu Tsai Neuro, 2024)Neuroscientists use AI to simulate how the brain makes sense of the visual world (Wu Tsai Neuro, 2024)How Artificial Neural Networks Help Us Understand Neural Networks in the Human Brain (Stanford Institute for Human-Centered AI (HAI), 2021)Related researchA Task-Optimized Neural Network Replicates Human Auditory Behavior...

All the colours of the rainbow, plus oneResearchers have fired lasers directly into the eye to stimulate photoreceptors, and produce the perception of a colour that does not exist in nature. They describe it as a “supersaturated teal,” and hope the technique will allow them to better understand colour vision and perhaps lead to treatments for vision problems.

The footprints belonged to a club-tailed ankylosaur about five to six metres long, and are the first evidence of this type of dinosaur living in North America in a period known as the middle Cretaceous. The research was led by Victoria Arbour, curator of paleontology at the Royal B.C. Museum, and published in the journal Vertebrate Paleontology.Did the Neanderthals die from sunburn?Neanderthals disappeared 40,000 years ago, and new research suggests this corresponds to a period of weakness in the Earth's magnetic field that allowed an increase in the solar radiation reaching the surface. Researchers think they have evidence that modern humans were able to protect themselves from the sun better than Neanderthals could, and this might have contributed to the Neanderthal extinction. Raven Garvey is an anthropologist at the University of Michigan. Her team's research was published in the journal Science. Cloudy with a chance of ammonia mushballsNew observations and models of activity within Jupiter's stormy atmosphere is giving a weather report for the giant planet, and it's pretty extreme. Most interestingly, researchers predict conditions that could lead to violent lightning storms producing softball sized frozen ammonia “mushballs” that would rain through the upper atmosphere. The research was led by Chris Moeckel, a planetary scientist and aerospace engineer at the University of California-Berkeley Space Sciences Laboratory, and was published in the journal Science Advances.Shattering heat records: climate change is turning out to be worse than expectedIn the last few years, we've seen global temperatures rising faster, with more extreme localized heatwaves, than climate models predicted. Climate scientists are trying to understand this by investigating the underlying factors behind these heating trends. Richard Allan, from the University of Reading in the U.K., was expecting a larger than normal rise in global temperatures due to natural fluctuations, but global temperatures in 2023 and 2024 were much higher than expected. Their recent study in the journal Environmental Research Letters found a growing imbalance in the earth's heat system, with increasingly more heat coming in than leaving, in large part due to changes we've seen in global cloud cover.This global heating is not happening evenly around the world. Kai Kornhuber, from the International Institute for Applied Systems Analysis in Austria and Columbia Climate School in New York, found regional hotspots that are experiencing unexpected extreme heat, likely due to a combination of factors. That study is in the journal PNAS.

Critical Midlife Strategies to Prevent Age-Related Brain Decline: In this episode, Nutritionist Leyla Muedin “Weighs In” with a landmark study published in PNAS, highlighting the importance of a critical midlife window to prevent age-related brain decline. Conducted by scientists from Stony Brook University and other renowned institutions, the study reveals that brain aging follows a non-linear trajectory with key transition points starting as early as age 44. The research identifies neuronal insulin resistance and metabolic changes as primary drivers, suggesting dietary interventions like ketogenic diets during midlife can provide significant benefits. Leyla emphasizes the importance of early metabolic health monitoring and lifestyle changes to mitigate cognitive decline, addressing the growing concern of Alzheimer's and related neurodegenerative diseases.

On a longtemps pensé que le vieillissement du cerveau était un processus progressif et linéaire. Pourtant, une étude publiée en 2022 dans la revue scientifique PNAS — Proceedings of the National Academy of Sciences — révèle une réalité bien différente : le cerveau ne vieillirait pas de façon continue, mais par à-coups, avec un tournant brutal autour de 44 ans.Cette étude, menée par des chercheurs allemands et britanniques, s'appuie sur l'analyse de données d'imagerie cérébrale provenant de plus de 4 000 personnes âgées de 18 à 88 ans. En se basant sur une technique appelée « connectomique », les scientifiques ont cartographié les réseaux de communication entre différentes régions du cerveau. Leur objectif : comprendre comment ces connexions évoluent avec l'âge.Leur découverte principale est frappante : vers 44 ans, la structure du cerveau connaît une réorganisation brutale. C'est un peu comme si, à cet âge, les lignes de communication dans le cerveau étaient redirigées, certains circuits étant désactivés tandis que d'autres deviennent plus actifs. Ce basculement marque le début d'un déclin dans la rapidité et l'efficacité des échanges neuronaux. Concrètement, cela pourrait expliquer pourquoi, passé la quarantaine, certaines fonctions cognitives — comme la mémoire de travail, la vitesse de traitement ou la concentration — commencent à diminuer plus visiblement.Mais attention : ce n'est pas une fatalité. Ce changement ne signifie pas une dégénérescence irréversible, ni une perte de capacités immédiate. Il s'agit plutôt d'un tournant neurologique : le cerveau devient un peu moins plastique, un peu moins efficace dans sa manière de traiter et de transmettre l'information.Fait intéressant, l'étude montre aussi que toutes les régions du cerveau ne sont pas touchées de la même manière. Les zones les plus affectées sont celles impliquées dans des fonctions dites "supérieures", comme le raisonnement, le langage ou la prise de décision. En revanche, les zones sensorielles et motrices restent relativement stables plus longtemps.Ces résultats ont des implications majeures. D'abord, ils nous rappellent l'importance de préserver la santé du cerveau dès la quarantaine — voire avant — par une alimentation équilibrée, une activité physique régulière, un bon sommeil et une stimulation intellectuelle continue.En somme, selon cette étude parue dans PNAS, le cerveau humain pourrait connaître un tournant critique vers 44 ans. Un moment charnière, non pas pour s'alarmer, mais pour agir, en adoptant des habitudes qui favorisent un vieillissement cérébral en douceur. Hébergé par Acast.

Listen in as Real Science Radio host Fred Williams and co-host Doug McBurney review and update some of Bob Enyart's legendary list of not so old things! From Darwin's Finches to opals forming in months to man's genetic diversity in 200 generations, to carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations simply defy the claim that the earth is billions of years old. Real science demands the dismissal of the alleged million and billion year ages asserted by the ungodly and the foolish. * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner. * Finches Speciate in Two Generations vs Two Million Years for Darwin's Birds? Darwin's finches on the Galapagos Islands are said to have diversified into 14 species over a period of two million years. But in 2017 the journal Science reported a newcomer to the Island which within two generations spawned a reproductively isolated new species. In another instance as documented by Lee Spetner, a hundred birds of the same finch species introduced to an island cluster a 1,000 kilometers from Galapagos diversified into species with the typical variations in beak sizes, etc. "If this diversification occurred in less than seventeen years," Dr. Spetner asks, "why did Darwin's Galapagos finches [as claimed by evolutionists] have to take two million years?" * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks. See this also from creationists by a geologist, a paleobiochemist, and a nuclear chemist. * Blue Eyes Originated Not So Long Ago: Not a million years ago, nor a hundred thousand years ago, but based on a peer-reviewed paper in Human Genetics, a press release at Science Daily reports that, "research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today." * Adding the Entire Universe to our List of Not So Old Things? Based on March 2019 findings from Hubble, Nobel laureate Adam Riess of the Space Telescope Science Institute and his co-authors in the Astrophysical Journal estimate that the universe is about a billion years younger than previously thought! Then in September 2019 in the journal Science, the age dropped precipitously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things! * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T. Rex, hadrosaur, titanosaur, triceratops, Lufengosaur, mosasaur, and Archaeopteryx, and many others dated, allegedly, even hundreds of millions of years old, have yielded their endogenous, still-soft biological material. See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including: - in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa. - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations! The journal Nature reports The Recent Origin of Most Human Protein-coding Variants. As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts. - The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies evolving too quickly,

Most iguanas are indigenous to the Americas. So how did the Fijian species end up on the island, nearly 5000 miles away in the South Pacific? According to a new study in the journal PNAS, it was probably via raft ... that is, on clump of floating trees. And this rafting hypothesis isn't entirely unprecedented. After hurricanes Luis and Marilyn hit the Caribbean in the 1990s, researchers found that a group of iguanas had floated over 180 miles away from Guadeloupe to the territory of Anguilla.

durée : 00:05:05 - Avec sciences - par : Alexandre Morales - Une publication parue dans la revue PNAS dévoile une méthode pour produire des anticorps simplifiés, plus facilement et pour moins cher. Une spectaculaire avancée thérapeutique.
L'augmentation progressive de la taille du cerveau humain au cours de l'évolution est un phénomène fascinant, qui a accompagné le développement de nos capacités cognitives. Mais quels sont les mécanismes qui ont conduit à cette évolution ? Une récente étude, publiée dans la revue PNAS, apporte un éclairage nouveau sur ce sujet en analysant les volumes crâniens sur une période de 7 millions d'années.Une croissance graduelle au sein des espècesLes chercheurs ont distingué deux dynamiques dans l'évolution du cerveau : celle qui se produit au sein d'une espèce et celle qui intervient entre différentes espèces. En examinant les données fossiles, ils ont constaté que, pour chaque espèce humaine étudiée, la taille du cerveau augmentait progressivement au fil du temps. Ce phénomène pourrait être lié à la sélection naturelle, qui favorise les individus aux capacités cognitives supérieures, leur permettant de mieux s'adapter à leur environnement.Une évolution liée aux changements environnementaux et sociauxL'augmentation de la taille du cerveau ne s'est pas produite au hasard. Plusieurs facteurs ont joué un rôle clé, notamment les changements environnementaux et les pressions de sélection qui en ont découlé. Par exemple, les ancêtres des humains modernes ont dû faire face à des climats instables, les obligeant à développer des stratégies de survie plus complexes. La fabrication d'outils, la chasse en groupe et l'émergence du langage ont ainsi contribué à renforcer l'intelligence et, par conséquent, à favoriser les individus ayant un cerveau plus développé.Des transitions entre espèces avec des sauts évolutifsL'analyse montre également que si, au sein d'une même espèce, la croissance du cerveau est progressive, des sauts évolutifs ont eu lieu lors des transitions entre différentes espèces. Par exemple, le passage de Homo habilis à Homo erectus, puis à Homo sapiens, a été marqué par des augmentations significatives du volume crânien. Ces sauts pourraient être liés à des innovations majeures, comme la maîtrise du feu ou l'amélioration des structures sociales, qui ont offert un avantage évolutif aux individus dotés d'un cerveau plus grand.Une augmentation qui a des limitesSi le cerveau humain a continué de croître pendant des millions d'années, cette tendance semble s'être stabilisée depuis quelques milliers d'années. En effet, un cerveau plus grand demande plus d'énergie et entraîne des contraintes physiologiques. L'évolution semble désormais privilégier une meilleure efficacité cérébrale plutôt qu'une simple augmentation de taille. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

As soon as the last ice age glaciers melted, Indigenous people occupied this siteA recently discovered archaeological site in Saskatchewan, dated to just less than 11,000 years ago is the oldest settlement in the region by about 1,500 years. It also is evidence that Indigenous people settled there as soon as the environment could support them after the glaciers disappeared. Glenn Stuart, from the University of Saskatchewan, is one of the archaeologists working along with local Indigenous community members to preserve and study the site.Just the right magnetic field will make sea turtles do a ‘happy dance'Researchers investigating how sea turtles navigate the vast and trackless ocean have discovered just how sensitive the reptiles' magnetic sense is, as they can even use it to identify the location of food resources. While feeding the loggerhead turtles in the lab, Kayla Goforth, a postdoctoral researcher at Texas A&M University noticed that the turtles would perform a ‘happy dance' when they recognized the right magnetic signature. She led this research that was published in the journal Nature.Intense exercise causes our bodies to belch out DNA that may reduce inflammationScientists were surprised to discover that the more intensely you exercise, the more certain immune cells belch out fragments of DNA that can form webs to trap pathogens, and lead to fewer pro-inflammatory immune cells circulating in our blood. Canadian researcher Stephen Montgomery, a professor of pathology at Stanford University, said their findings suggest that circulating cell-free DNA may play a role in how exercise lowers inflammation in the body. The study was published in the journal PNAS. An ancient Antarctic duck lived at the time of T-RexBirds are the last surviving lineage of dinosaurs, but modern birds are surprisingly ancient – dating to before the extinction of the rest of their family. An extremely rare, nearly intact bird skull found in Antarctica and dated to about 69 million years ago confirms this. This waterfowl had similarities to ducks and loons. Chris Torres is an assistant professor at the University of the Pacific in Stockton California and was part of the team that analyzed this fossil. Their research was published in the journal Nature.Science is being transformed by the AI revolutionThe stunning advances in artificial intelligence that we see with internet AI apps are just the tip of the iceberg when it comes to science. Researchers from almost every field are experimenting with this powerful new tool to diagnose disease, understand climate change, develop strategies for conservation and discover new kinds of materials. And AI is on the threshold of being able to make discoveries all by itself. Will it put scientists out of a job?Producer Amanda Buckiewicz spoke with:Jeff Clune, a professor of computer science at the University of British Columbia, a Canada CIFAR AI Chair at the Vector Institute, and a senior research advisor to DeepMind. He's also a co-author of The AI Scientist.Allison Noble, a Professor of Biomedical Engineering at the University of Oxford and a Foreign Secretary at the Royal Society, and chair of the Science in the Age of AI working group.Elissa Strome, executive director of the Pan-Canadian Artificial Intelligence Strategy at CIFAR.Cong Lu, postdoctoral research and teaching fellow at the University of British Columbia and the Vector Institute, and a co-author of The AI Scientist.Fred Morstatter, a research assistant professor at the University of Southern California, and a principal scientist at USC's Information Sciences Institute.
A little bit of scratching can do some good, but too much can hurtScratching an itch can feel great, so scientists decided to dig into why that is the case since we know too much scratching isn't good for us. Dr. Dan Kaplan, a professor of dermatology and immunology at the University of Pittsburgh, said they found that scratching drives inflammation to the skin, which, in light moderation, helps to fight bacterial skin infections. But he warns that continual or excessive scratching can prolong an itch and potentially damage the skin. Their study is in the journal Science. Bear hazing goes high-tech with dronesA wildlife manager in the US has found that drones can be a safe and effective way to discourage problem bears from troubling human habitation and livestock. Wesley Sarmento started working in the prairies of Montana to prevent bear-human conflicts, but found the usual tricks of the trade were not as effective as he wanted them to be. Previously he tried to use noisemakers, dogs, trucks, and firearms, but buzzing bears with flying robots turned out to work much better. Now a PhD student at the University of Montana, he published an article about his hazing research in Frontiers in Conservation Science.Ants can remember and hold grudges against those who trouble themWhen ants fight with those from another nearby colony, it makes an impression. A new study has found the insects can remember the chemical signature of the aggressors, and will respond more vigorously and violently the next time they cross paths. Dr. Volker Nehring, a researcher at the University of Freiburg, Germany, describes the phenomenon as “the nasty neighbour" where ants are most aggressive to ant colonies closest to them, and says this is due to resource protection. Dr Nehring and his team's research was published in the journal Current Biology.Scientists on the front line of permafrost thaw describe changes in the Arctic The acceleration of change in the Arctic due to global warming is transforming the landscape on a year-to-year basis, often in surprising ways. That's according to scientists who've been studying the effects of climate change in the North. One study found that lakes in Western Greenland shifted from pristine blue to dirty brown from one year to the next due to increased permafrost melting and runoff. Jasmine Saros, a lake ecologist from the University of Maine, said they were astonished by the magnitude of change they saw in all 10 lakes they studied and how quickly it happened. That study was published in the journal PNAS. We also speak with William Quinton, a permafrost hydrologist from Wilfred Laurier University and the director of the Scotty Creek Research Station in southern Northwest Territories, an area he describes as “the frontline of permafrost thaw.” Quinton was part of a research team, led by Anna Virkkala from the Woodwell Climate Research Centre, that found that 34 per cent of the Arctic Boreal Zone — a region where carbon was safely locked up in the permafrost for thousands of years — has now become a carbon source. That study is in the journal Nature Climate Change.

VYS0047 | The Weird Review Of The Year 2024 - Show Notes [Caution: This episode contains an extreme weariness for bullshit that some listeners may find triggering] 2024 was a tough year, weird but tough. And looking back over it doesn't make it any better. In what amounts to a rapid and inexorable descent into madness Hine and Buckley pick apart the weird and, frankly, fucking dystopian year that was 2024. Bouncing between jaded despair and hysterical mania the Vayse boys mull over the topics that dominated 2024: UFOs, Artificial Intelligence and Elon Fucking Musk. Whilst stumbling around in the intoxicating embrace of the seemingly endless darkness they also uncover strange stories of interconnected dreams, robot dogs with flame throwers, robot faces with living skin, bowls of goo with pong skills, plots to genetically engineer super-sheep, a surprising number of goblin attacks and perhaps, maybe, possibly a giant lake dwelling cow...?

⏳ Un orologio più preciso che mai?Giorgio ci racconta gli ultimi passi avanti verso la costruzione di un orologio nucleare, un dispositivo che potrebbe rivoluzionare il modo in cui misuriamo il tempo. A settembre 2024, un gruppo di ricercatori è riuscito a misurare con estrema precisione la frequenza necessaria a portare allo stato eccitato il nucleo di torio, un elemento chiave per questo tipo di orologi. Risultato? Se tutto va come sperato, presto potremmo avere il primo orologio nucleare della storia, ancora più stabile e accurato degli attuali orologi atomici. A quel punto, scordatevi le scuse per arrivare in ritardo!Per approfondire:ArticoloNews da NatureI ragni annusano con le zampe!Ilaria, invece, ci porta nel mondo affascinante (e un po' inquietante) dei ragni. Nonostante siano nostri vicini di casa da sempre, ci sono ancora tantissime cose che non sappiamo su di loro. Per esempio: come fanno a sentire gli odori? Un recente studio pubblicato su PNAS ha finalmente risolto il mistero. I maschi di ragno usano delle microscopiche setole sensoriali sulle zampe, chiamate wall-pore sensilla, che funzionano come un vero e proprio naso. Grazie a questi peli speciali, riescono a captare i feromoni rilasciati dalle femmine e a trovarle per l'accoppiamento. Insomma, per un ragno, annusare con le gambe è la norma.ScientifiBook – I consigli del meseNon poteva mancare la nostra rubrica dedicata ai libri!

Reintroducing Hawaii's sacred crow to the wildThe world's most endangered crow, the Hawaiian crow or or ʻalalā, is making tentative steps towards a comeback. After going extinct in the wild, only 120 birds remain in captivity, in two facilities operated by the San Diego Zoo. Over the years, researchers have attempted reintroductions in the bird's native habitat on the Big Island of Hawaii, but those efforts have all been unsuccessful. Recently, the team tried something different - reintroducing the birds to a different island than their native home. The initial release happened in October and so far, the team, including Bryce Masuda, has high hopes and positive signs from their latest attempt.Lasers tell us about the pterosaur's unique tailThe great flying reptiles of the dawn of the age of dinosaurs, the pterosaurs, took flight with delicate but flexible internal tail structure that allowed it to work like a kite. Scientists used recently developed technology to enable them to see a lattice-like structure in the soft tissue in the early pterosaur soft tissue that was otherwise invisible to the naked eye. Natalia Jagielska, a paleontologist at the Lyme Regis Museum in Dorset, England, said their kite-like tail vane would have stood upright and could have functioned as a display and to help them in flight. The study was published in the eLife journal, Evolutionary Biology. How gophers help re-seed volcanic landscape with lifeAfter Mt. St. Helens exploded in 1980 it left a shattered, ash-covered, barren landscape behind. But the one-time reintroduction of gophers to one area led to a remarkably fast recovery of plants and other fauna. Forty-years later, changes to the environment are still being documented by Dr. Mia Maltz, assistant professor of Microbial Ecology and Soil Earth at the University of Connecticut, and her team. They published their research in the journal Frontiers in Microbiomes.Desert ants' magnetic navigationDesert ants that navigate the endless sands of the Sahara use the Earth's magnetic field to find their way, which is not unusual. But unlike other animals like birds and turtles they don't appear to have an internal compass that aligns north and south. Instead they are unique in that they use a more subtle cue – the polarity of the magnetic field. A study looking at this led by Dr. Pauline Fleischmann, a post-doctoral researcher at the University of Oldenburg in Germany was published in the journal Current Biology. Celestial body mysteries: dark comets and meteorites from young asteroid families The thousands of small celestial bodies in our solar system are now a bit less mysterious, thanks to several recent discoveries. One group of astronomers have traced back the origins of 84 per cent of all known meteorites that have pummeled Earth to just a few young asteroid families in the asteroid belt. Michaël Marsset, from the European Southern Observatory in Chile, said collisions in the asteroid belt create a collisional cascade that produces fragments, some of which end up raining down on Earth as meteorites. Two of their papers were published in the journal Nature and a third in Astronomy & Astrophysics. Another group of astronomers have identified two populations of stealthy dark comets that are something in between a comet and an asteroid. They've found fourteen of these objects whose orbital motion is comet-like, but which lack a visible tail like regular comets. Davide Farnocchia, a navigation engineer at NASA's Jet Propulsion Lab, said they've found two types of these unusual solar system bodies: larger ones in an elliptical orbit out to Jupiter and smaller ones in orbit around Earth. Their study was published in the journal PNAS.

Was Rome's fall due to heavy metal poisoning making Romans dumber?Ice cores that preserve traces of atmospheric pollutants through history have revealed that industrial activity by Romans – particularly the use and production of lead – meant the air the Romans breathed was heavily contaminated. The levels were high enough to cause neurological problems, including a drop in cognitive function across the population. Joe McConnell and his team at the Desert Research Institute published their findings in the journal PNAS.Bats are surfing storms to make migration easierMigrating bats in Europe have to fly up to 2000km while pregnant, but they've figured out how to get a lift from the weather. The bats have been observed waiting for storm fronts, and then surfing the strong winds in front of the storm to save energy during their migration. Dina Dechmann from the Max Planck Institute of Animal Behaviour, and colleagues, were able to tag bats with tiny specialized sensors to track their nocturnal movements during migration. Their paper was published in the journal Science.Squirrels have developed a taste for vole fleshSquirrels in California have been taking advantage of a boom in the population of tiny rodents called voles – by hunting and eating them. This widespread carnivorous behaviour was captured for the first time on videos and photos by a team led by behavioural ecologist Jennifer Smith, as a part of a long-term study of the squirrels. The researchers found dozens of instances of the squirrels killing the voles, which they say changes our fundamental understanding of ground squirrels. Their paper was published in the Journal of Ethology.EEG tattoos could outperform standard electrodes EEG is a valuable technology that allows researchers to monitor the electrical activity of the brain, but standard EEG electrodes are cumbersome and are hampered by the difficulty of attaching them. A new temporary EEG tattoo, made by printing conductive ink on the scalp, could be a step ahead. Luize Vasconcelos, a postdoctoral fellow at the University of Texas at Austin helped create this ink. The research is published in the Cell Press journal Cell Biomaterials.To monitor cat brain waves, researchers made them cute hatsAude Castel, a veterinary neurologist from the Université de Montréal, and her team were studying chronic pain in cats — and ways to alleviate it — when she realized that she could crochet hats for the cats and add EEG electrodes to them in order to study their brains. Their research was published in the Journal of Neuroscience Methods. When North America went to the dogs (or vice-versa)Researchers examining canid bones from Alaska dating to the last ice age have been intrigued by the complex picture it shows of dog domestication at the time. Their findings were published in the journal Science Advances. Signs of the animals' diet are preserved in the bones, and shows that humans were clearly feeding their dogs, a clear sign of domestication. François Lanoë from the University of Arizona led the work.

Early people in North America had mammoth appetitesThe people of the Clovis culture, who lived across Ice Age North America 13,000 years ago, left behind many tools and artifacts that suggest they were skilled hunters. And now chemical analysis of the incredibly rare find of bones of a Clovis child has given us the first direct evidence of what they were eating. The research, co-led by James Chatters of McMaster University, revealed they were “super-carnivores” whose diet mostly consisted of mammoth meat, with elk and bison/camel showing up as well. By specializing in hunting megafauna, this would have helped the Clovis people rapidly spread throughout North America. The research was published in the journal Science Advances.Now we know the specific molecule that makes the Corpse flower smell like deathCorpse flowers are major botanical attractions because of their unique shape, their rare flowering and their incredible stench. Now researchers have identified the molecule that is the secret behind the stink. Alveena Zulfiqar, a research associate at the University of Minnesota, was a key part of the team led by G. Eric Schaller, a professor of biology at Dartmouth College. They published their research in the journal PNAS Nexus.The dinosaurs that became birds had distinctive drumsticksThe lineage of dinosaurs that ultimately evolved into birds didn't just have unique adaptations for wings and feathers. They also evolved unique drumsticks, specifically fibula bones that are detached at the ankle, which gave their knee joints unusual mobility, allowing them to twist by more than 100 degrees. Biomechanist Armita Manafzadeh, from Yale University, says it's certainly possible that this change in their mobility might have been key to their survival. Their research was published in Nature. A plant can spit out its seeds fast enough to take out an eyeIn the blink of an eye the squirting cucumber can eject its seeds faster than a greyhound can run, up to twelve meters from the plant. High speed video has enabled researchers to capture the process, which the plant manages without muscles or tendons. Derek Moulton, a professor of applied mathematics at the University of Oxford, was part of the team that published their research in the journal PNAS.Hacking photosynthesis: How we can improve the chemistry that's the foundation of lifeThe plants that make up the base of the Earth's food chain, use the sun's energy — along with carbon dioxide and water — to build their tissues. But the chemical process they use, photosynthesis, is extremely inefficient. To feed our growing population, scientists are working on ways to improve this very foundational chemical reaction by increasing its efficiency.One team developed a computer simulation of the entire photosynthetic process to systematically search for and test ways to enhance the process. Plant biologist Steve Long, from the University of Illinois at Urbana-Champaign, says if they combined all the individual gains they've discovered, he estimates they could improve efficiency by up to double. One of their latest studies is currently in the preprint bioRxiv. Another approach scientists are investigating involves replacing photosynthesis with more efficient chemical reaction to produce acetate as fuel for the plants' growth. This reaction could be powered by solar energy or any other form of electricity. Robert Jinkerson, a chemical engineer from the University of California in Riverside, said they're still developing this technology for plants, but they've shown that in single-celled photosynthetic algae that they can improve photosynthetic efficiency by at least four-fold. Their research is published in Joule.
Octopus camouflage is incredibly hard workOctopuses have the remarkable ability to change their appearance in the blink of an eye – assuming new skin coloration and patterns for camouflage or communication. A new study in the journal PNAS has explored how much energy this takes, and it turns out transforming themselves is a workout harder than you'd ever get at the gym. Dr. Kirt Onthank is a professor of Biology at Walla Walla University and known as The Octopus Guy on social media.Bigger isn't better when it comes to dog brainsDog bodies and brain sizes vary enormously, but a new study comparing dogs' cognitive abilities and personalities with brain size reveals some surprises. The research, led by evolutionary biologist Ana Balcarcel, found that the biggest brains relative to their body sizes belong to the small, anxious, excitable companion dogs, while the trainable, obedient working breeds are not gifted when it comes to volume of brain tissue. The work was published in the journal Biology Letters.This universe is too sparse, this one's too dense, and this one? Well, it'll doOur universe might seem like it's perfectly tuned for life, but when it comes to the role dark energy plays in the emergence of life, it turns out that our universe might not be so special after all. A new study that simulated the development of hypothetical universes with different amounts of dark energy suggests the optimal amount of dark energy to enable the evolution of life is only one-tenth of the density in our universe. Daniele Sorini, a postdoctoral researcher at Durham University and his team published their work in Monthly Notices of the Royal Astronomical Society. Why a smack on the lips might have come from a snack on a tickLip mashing is an oddity in the animal kingdom. Other than humans, few species have adopted the custom of pressing lips together as a signal of affection. A new theory for why humans kiss suggests it emerged from primate grooming practices, and the lip-lock has its roots in us slurping up parasites we've combed from a companion's fur. Dr. Adriano Lameira, an evolutionary psychologist at the University of Warwick published his new hypothesis in the journal Evolutionary Anthropology. Taking out our brains' trash may be key to maintaining a healthy brainSome scientists think it's possible that a host of neurological disorders, from Alzheimer's to Parkinson's, could be connected to problems with the way the brain rids itself of metabolic waste. A couple of recent studies in Nature are helping this longstanding puzzle about how this waste removal system works and what we might be able to do about it when it doesn't. A study published in Nature describes how synchronized electrical waves help flush the waste out when we sleep. Jonathan Kipnis, a neuroimmunologist from Washington University in St. Louis, said our neurons that are driving this waste removal system through what's known as the glymphatic system. A separate study of how gamma frequency stimulation, at 40 cycles per second, can kickstart gamma waves that are compromised in the brains of people with Alzheimer's. Li-Huei Tsai, a neuroscientist from MIT, said they found this stimulation flushes out beta-amyloid peptides in the brains of mice that would otherwise build up and form plaques which are the hallmark of diseased Alzheimer's brains.
