I'm still going through some older reruns for the summer due to my travel schedule. This one is an interview with Rocío Titiunik, a quantitative methods political scientist and professor in the department of politics at Princeton University, as well as a researcher that has been at the frontier of work on regression discontinuity designs. Her name is synonymous with cutting-edge work on regression discontinuity design, developed in close collaboration with scholars like Sebastián Calonico, Matías Cattaneo, and Max Farrell. Together, they've shaped the modern landscape of causal inference, not only through groundbreaking theory but also through widely used software tools in R, Stata, and Python. In addition to her contributions to quantitative methodology, Rocío's applied research — from electoral behavior to democratic institutions — has become a major voice in political science. She also holds a formidable editorial footprint: associate editor for Science Advances, Political Analysis, and the American Journal of Political Science, and APSR. It's no exaggeration to say she helps steer the field as much as she contributes to it.In this older interview, Rocío shared how her journey into economics began not with data, but with theory, literature, and the big questions that led her to the discipline. Her path into Berkeley's PhD program in agricultural and resource economics was anything but linear, and even once there, she wasn't sure how all the parts of herself — the scholar, the immigrant, the thinker — would fit together. During our conversation, she opened up about moments of uncertainty, of feeling lost in the sheer vastness of academic economics. Her honesty was disarming. It reminded me that no matter how decorated someone's résumé may be, we're all just trying to find our way — and sometimes, the most important breakthroughs happen when we admit we haven't arrived yet.Thanks again for tuning in!

First up on the podcast, South Africa's Cradle of Humankind is home to the world's greatest concentration of ancestral human remains, including our own genus, Homo, Australopithecus, and a more robust hominin called Paranthropus. Proving they were there at the same time is challenging, but new fossil evidence seems to point to coexistence. Producer Kevin McLean discusses what a multihominin landscape might have looked like with Contributing Correspondent Ann Gibbons.   Next on the show, should robots grow and adapt like babies?  Host Sarah Crespi talks with roboticist Philippe Wyder about a platform for exploring this idea. In his Science Advances paper, Wyder and his team demonstrate how simple stick-shaped robots with magnets at either end can join up for more complicated tasks and shed parts to adapt to new ones.   Philippe Wyder was at Columbia University and the University of Washington when he completed this work, and he has now moved on to a company called Distyl AI.   This week's episode was produced with help from Podigy.

In this episode of SpaceTime, we delve into fascinating connections between Earth's atmospheric conditions and its magnetic field, alongside intriguing insights into Mercury and the mysteries of the Sun's corona.Link Between Earth's Oxygen and Magnetic FieldA groundbreaking study published in Science Advances reveals a correlation between the fluctuations of Earth's magnetic field and atmospheric oxygen levels over the last 540 million years. Researchers suggest that processes within the Earth might influence habitability on the surface, highlighting the magnetic field's role in protecting our atmosphere from cosmic rays and solar wind. This correlation raises questions about the underlying processes linking these two critical elements for life on Earth.Unraveling Mercury's SecretsNew findings indicate that Mercury's crust and internal structure are unlike any other planet in our solar system. Laboratory simulations are aiding the European-Japanese BepiColombo mission, set to orbit Mercury in November 2026. Researchers are investigating why Mercury's core constitutes 60% of its volume, exploring theories about its metal-rich composition and volcanic history. The study emphasizes the need for more data to understand Mercury's unique characteristics and geological processes.The Ongoing Mystery of the Sun's CoronaDespite advancements in solar research, the heating of the Sun's corona remains a significant puzzle. Observations from NASA's IRIS mission and other spacecraft are shedding light on potential mechanisms, including magnetic reconnection and plasma waves. These studies are revealing the complexity of the solar atmosphere and could help scientists understand how energy is transferred from the Sun's surface to its outer layers.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvNASA IRIS Missionhttps://iris.lmsal.com/European Space Agencyhttps://www.esa.int/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 77 for broadcast on 27 June 202501:00 Link between Earth's oxygen and magnetic field12:15 Unraveling Mercury's secrets22:30 The ongoing mystery of the Sun's corona30:00 Science report: Changing seasonal rhythms and their impact on ecosystems

Mutant super-powers give Korean sea women diving abilitiesThe Haenyeo, or sea women, of the Korean island of Jeju have been celebrated historically for their remarkable diving abilities. For hour after hour they dive in frigid waters harvesting sea-life, through pregnancy and into old age. A new study has shown they are able to do this because of specific genetic adaptations that appeared in their ancestors more than a thousand years ago. These genes make them more tolerant to the cold, and decrease diastolic blood pressure. The women also spend a lifetime training, beginning to dive at age 15 and continuing on until their 80s or even 90s. Melissa Ilardo of Utah University and her team published their findings in the journal Cell Reports.This dessert is automatic and autonomous Care for a slice of robo-cake? Scientists in Europe have baked up a cake with pneumatically powered animated gummy bears, and candles lit by chocolate batteries. They think their edible robotics could develop in the future to food that could bring itself to the hungry and medicine could deliver itself to the sick. Mario Caironi of the Italian Institute of Technology and his colleagues presented their creation at Expo 2025 Osaka.Shrinking Nemo — heat is causing clownfish to downsizeScientists have found that clownfish, made famous by the Disney movie Finding Nemo, have an ability never seen before in fish in the coral reefs. When the water they live in gets warmer, they are able to shrink their bodies — becoming a few per cent of their body length shorter — to cope with the stress of the heat. Melissa Versteeg of Newcastle University says the size of the clown anemonefish is important for their survival and their ranking within their hierarchical society. The research was published in the journal Science Advances.When the music moves you — the brain science of grooveYou know that groove feeling you get when you listen to certain music that compels you to shake your bootie? Scientists in France investigated how our brains experience groovy music to better understand how we anticipate rhythms in time. They discovered that we perceive time in the motor region that controls movement. Benjamin Morillion from Aix Marseille Université said they also found a specific rhythm in the brain that helps us process information in time, that could predict if a person thought the music was groovy. The study was published in the journal Science Advances.Scientists hope a new storm lab will help us understand destructive weatherExtreme weather is far less predictable than it used to be, and now a new research centre at Western University wants to transform our understanding of Canada's unique weather systems.

Researchers, led by Konstantin Batygin, used the orbits of Jupiter's small moons, Amalthea and Thebe, to deduce these findings, providing critical insights into the early stages of planetary formation. The implications of this research could reshape our understanding of gas giants and their formation processes across the universe.Gamma Rays and LightningIn a groundbreaking discovery, scientists have detected intense flashes of gamma rays produced by lightning strikes. This phenomenon, known as terrestrial gamma ray flashes, occurs when lightning accelerates electrons to near light speeds, resulting in bursts of radiation. The study, published in Science Advances, sheds light on the high-energy processes occurring in Earth's atmosphere, enhancing our understanding of lightning's power and its effects on our planet.Precision Formation Flying in SpaceHistory has been made in Earth orbit as two spacecraft from the European Space Agency's Proba 3 mission successfully flew in millimeter-perfect formation for the first time. This precision alignment is crucial for studying the Sun's corona, allowing the two satellites to simulate a single large spacecraft. We discuss the technology behind this mission and its potential to revolutionize solar observations.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Astronomyhttps://www.nature.com/natureastronomy/Science Advanceshttps://www.science.org/journal/sciadvBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 64 for broadcast on 28 May 202501:00 Jupiter's original size and magnetic field12:15 Gamma ray flashes unleashed by lightning22:30 Precision formation flying in space30:00 Science report: New contact lens technology for night vision

Can artificial intelligence transform how we navigate the most challenging dialogues on campus? Join us for a thought-provoking episode featuring philosopher and educator Simon Cullen, as he unveils his pioneering work at the intersection of education, technology, and constructive disagreement.In conversation with John Tomasi, Simon explores how open inquiry is both advanced and imperiled by disagreement, and describes his academic journey from Australia to Princeton and Carnegie Mellon. Central to the discussion is ‘Sway' an AI-powered platform developed by Simon and his team to foster rigorous, evidence-based dialogue among students on controversial topics. Sway intelligently pairs students with opposing views and acts as a “guide on the side,” scaffolding reasoning, encouraging intellectual humility, and ensuring that exchanges remain constructive and charitable. Simon shares the empirical findings from thousands of Sway-mediated dialogues, where measurable increases in students' openness, comfort, and analytical reasoning have been observed—even on divisive subjects like gender, immigration, and the Israel-Palestine conflict. In This Episode:

The beginnings of our end — where the anus came from Our distant evolutionary ancestors had no anuses. Their waste was excreted from the same orifice they used to ingest food, much like jellyfish do today. Now a new study on bioRxiv that has yet to be peer-reviewed, scientists think they've found the evolutionary link in a worm with only a single digestive hole. Andreas Hejnol, from Friedrich Schiller University Jena, said he found genes we now associate with the anus being expressed in the worms in the opening where its sperm comes out, suggesting that in our evolutionary history a similar orifice was co-opted as a butt hole. Deepfake videos are becoming so real, spotting them is becoming increasingly diceyDetecting deepfake videos generated by artificial intelligence is a problem that's getting progressively worse as the technology continues to improve. One way we used to be able to tell the difference between a fake and real video is that subtle signals revealing a person's heart rate don't exist in artificially generated videos. But that is no longer the case, according to a new study in the journal Frontiers in Imaging. Peter Eisert, from Humboldt University and the Fraunhofer Heinrich-Hertz-Institute HHI in Germany, said detecting manipulated content visually is only going to become a lot more difficult going forward. Crows can use tools, do math — and now apparently understand geometryCrows are known to be among the most intelligent of animals, and a new study has explored their geometrical sophistication. Researchers including Andreas Nieder from the University of Tübingen found that crows can recognize and distinguish different kinds of quadrilateral shapes, an ability we had thought was unique to humans. The research was published in the journal Science Advances.There's gold in them thar magnetically charged neutron stars!Astronomers have discovered a new source of the universe's heavy elements — things like gold, platinum and uranium. A study led by astrophysicist Anirudh Patel found that magnetars — exotic neutron stars with ultra-powerful magnetic fields — may produce these elements in a process analogous to the way solar flares are produced by our Sun. The research, published in The Astrophysical Journal Letters, found that a single flare from a magnetar could produce the mass equivalent of 27 moons' worth of these heavy elements in one burst.It may not be big, but it's small — and stroppyYou might not expect an insect so tiny you need a magnifying glass to see it properly to be an aggressive defender of its territory, but that's because you haven't met the warty birch caterpillar. Its territory is just the tip of a birch leaf, but it defends it by threatening intruders with vigorous, if not precisely powerful, vibrations. Jayne Yack at Carleton University has been studying this caterpillar since 2008. This research was published in the Journal of Experimental Biology.Criminals beware — the microbiome leaves fingerprintsScientists have developed a new tool that can track location based on traces of the bacteria characteristic to different places. Eran Elhaik, from Lund University in Sweden, trained the AI tool using nearly 4,500 microbiome samples collected around the world from subway systems, soil and the oceans. He said they could identify the city source in 92 per cent of their urban samples, and in Hong Kong, where a lot of their data came from, they could identify the specific subway station samples were taken from with 82 per cent accuracy. The study was published in the journal Genome Biology and Evolution.

I'm Stacey Simms and every other Friday I bring you a short episode with the top diabetes stories and headlines happening now. XX A world-first human trial of a drug designed to treat the underlying cause of type 1 diabetes has begun in Australia. University of Queensland researcher Ranjeny Thomas said the experimental drug — dubbed ASITI-201 — was designed to retrain the immune system so it no longer attacks the insulin-producing pancreatic cells, known as beta cells. The drug, given as an injection under the skin, combines fragments of a protein found in the beta cells of people with type 1 diabetes and vitamin D to calm the immune response. She said if effective, the drug would initially be given to patients with type 1 diabetes as soon as possible after diagnosis to preserve remaining pancreatic cells and reduce the amount of insulin needed. But eventually, if screening programs can be developed to pick up people at risk of developing type 1 diabetes, it may be possible to "prevent the progression of the disease altogether". The first in-human trial of 36 participants will test the safety of the drug, but blood tests will also determine the impact of the therapy on a patient's immune system and glucose tolerance. https://www.abc.net.au/news/2025-04-29/type-1-diabetes-drug-trial-auto-immune-disease-science/105223022 XX   Diabetes deaths in the U.S. have fallen to some of the lowest rates in years, according to new preliminary figures published by the Centers for Disease Control and Prevention, reversing a surge in mortality that was seen during the COVID-19 pandemic.   There were 26.4 deaths per 100,000 people from diabetes, according to early death certificate data for the third quarter of 2024 published this month by the CDC's National Center for Health Statistics.   Death rates from diabetes peaked in 2021, according to CDC figures, at 31.1 deaths per 100,000 people for that year. Diabetes was the eighth leading cause of death in 2021. The CDC says the link between COVID-19 and diabetes may be to blame for that increase.   "Data show an increase in mortality rates for all people during the COVID-19 pandemic, and research shows that people with underlying conditions, including diabetes, are more likely to become very sick from COVID-19 and have a higher risk of hospitalization and death," Christopher Holliday, head of the CDC's Division of Diabetes Translation, told CBS News in a statement.   Holliday added that research shows the pandemic may also have made it harder for Americans to properly manage the disease, ranging from interruptions to physical activity to disruptions to routine medical care diagnosing and treating the disease.   https://www.cbsnews.com/news/diabetes-deaths-lowest-levels-years-early-cdc-figures/ XX Big news for the Eversense CGM – they have their first pump partner. Sequel Med Tech says the twist pump will integrate with Senseonics Eversense 365 continuous glucose monitor (CGM). This collaboration would make twiist the first AID system compatible with Eversense 365, the world's first and only one-year CGM. Sequel and Senseonics say they have already started their work to integrate the latest-generation, 365-day implantable sensor with twiist. They expect to make the integrated offering available in the third quarter of this year. This marks the second CGM integration for Sequel, which partnered with Abbott and its FreeStyle Libre platform earlier this year. This week we also got a peek at the packaging and delivery of the twist as the first people posted about wearing it. We'll follow up and learn more about this newest insulin pump in the us. Senseonics, meanwhile, brought the first year-long CGM to market last year, launching Eversense 365 with its global distribution partner, Ascensia Diabetes Care, in October 2024. The system also received clearance as an integrated CGM (iCGM) system, meaning it can work with compatible medical devices. Those include insulin pumps as part of automated insulin delivery systems. https://www.drugdeliverybusiness.com/sequel-senseonics-integrate-cgm-insulin-pump/ XX Medtronic has announced the U.S. Food and Drug Administration (FDA) approval for the Simplera Sync sensor for use with the MiniMed 780G system. With this approval, the MiniMed 780G system now offers more flexibility for users of the company's most advanced insulin delivery system featuring Meal Detection technology with both the Guardian 4 sensor and Simplera Sync sensor.   The Simplera Sync is a disposable, all-in-one sensor that requires no fingersticks with SmartGuard or overtape and features a simple, two-step insertion process. It is the company's newest addition to its CGM portfolio, which expands options and provides greater flexibility for users.   The MiniMed 780G system's adaptive algorithm automatically anticipates, adjusts, and corrects glucose levels every 5 minutes, 24/7 – working around the clock so users can focus on what matters. It's the only system featuring Meal Detection technology, which detects rising sugar levels and delivers more insulin as needed to help users keep glucose levels in range more often – even when users occasionally forget to dose insulin for snacks or meals or underestimate their carbs.   The system uses a “treat to target” approach and flexible glucose targets as low as 100 mg/dL, which, combined with its adaptive algorithm allows it to more closely mirror the glucose levels of someone not living with diabetes.   Real-world data of the system shows global users consistently achieve time in range above international targets of 70% when using optimal settings (active insulin time of two hours and 100 mg/dL target glucose). It is also the only system that works with the world's only infusion set that lasts up to 7 days so that users only have to change their infusion set once per week and can experience 96% fewer injections compared to multiple daily injections.   “We're committed to driving innovation that makes life easier for those living with diabetes so they can forget about their diabetes as much as possible throughout the day,” said Que Dallara, EVP and president of Medtronic Diabetes. “Our MiniMed 780G system delivers advanced diabetes technology for so many around the world, and we're excited to continue evolving this experience with expanded CGM options —including our Simplera Sync sensor, which we look forward to bringing to people living with diabetes in the U.S.”   A limited launch of the Simplera Sync sensor will begin in the U.S. in the fall of 2025. Today, the MiniMed 780G system can be used with the Guardian 4 sensor.   Like this:https://med-techinsights.com/2025/04/29/simplera-sync-sensor-for-minimed-780g-now-fda-approved/ XX Front office changes at Insulet.. The former head of Johnson & Johnson's worldwide medtech business, Ashley McEvoy will take over as president and CEO from Jim Hollingshead, who has led Insulet since 2022. In its announcement of the leadership change, Insulet said that Hollingshead and the company mutually agreed to part ways, effective immediately. McEvoy served as worldwide medtech chairman at J&J from 2018 until her departure in late 2023, the culmination of nearly 30 years at the company and several executive roles—including president of its Ethicon division and group chairman of vision and diabetes care. Since then, she has also served as a board member at Procter & Gamble. https://www.fiercebiotech.com/medtech/insulet-taps-former-jj-medtech-head-ashley-mcevoy-be-ceo XX New free mobile game launched this week to make type 1 diabetes onboarding faster easier and less overwhelming.

As the most abundant protein in the human body, collagen provides essential structure and support to nearly all tissues and organs.   Now, researchers at Carnegie Mellon's Feinberg Lab have made a major breakthrough using their novel Freeform Reversible Embedding of Suspended Hydrogels (FRESH) 3D bioprinting technique. This method enables the precise printing of soft, living cells and tissues. Leveraging this technology, the team successfully created the first-ever microphysiologic system, also known as a tissue model, constructed entirely from collagen. This advancement opens new possibilities for studying disease and engineering tissue therapies, including potential treatments for conditions like Type 1 diabetes.   Traditionally, small-scale models of human tissue, referred to as microfluidics, organ-on-chip devices, or microphysiologic systems, have been fabricated using synthetic materials such as silicone rubber or plastics. These materials were necessary due to limitations in earlier manufacturing techniques. However, because they are not biologically native, they fail to fully replicate natural tissue environments, restricting their effectiveness in biomedical research and therapeutic development.   “Now, we can build microfluidic systems in the Petri dish entirely out of collagen, cells, and other proteins, with unprecedented structural resolution and fidelity,” explained Adam Feinberg, a professor of biomedical engineering and materials science & engineering at Carnegie Mellon University. “Most importantly, these models are fully biologic, which means cells function better.”   Building Complex Tissues with FRESH Bioprinting In new research published in Science Advances, the group demonstrates the use of this FRESH bioprinting advancement, building more complex vascularized tissues out of fully biologic materials, to create a pancreatic-like tissue that could potentially be used in the future to treat Type 1 diabetes. This advancement in FRESH bioprinting builds on the team's earlier work published in Science, by improving the resolution and quality to create fluidic channels that are like blood vessels down to about 100-micron diameter.   “There were several key technical developments to the FRESH printing technology that enabled this work,” described Daniel Shiwarski, assistant professor of bioengineering at the University of Pittsburgh and prior postdoctoral fellow in the Feinberg lab. “By implementing a single-step bioprinting fabrication process, we manufactured collagen-based perfusable CHIPS in a wide range of designs that exceed the resolution and printed fidelity of any other known bioprinting approach to date. Further, when combined with multi-material 3D bioprinting of ECM proteins, growth factors, and cell-laden bioinks and integration into a custom bioreactor platform, we were able to create a centimeter-scale pancreatic-like tissue construct capable of producing glucose-stimulated insulin release exceeding current organoid based approaches.” https://scitechdaily.com/scientists-bioprint-living-tissues-that-could-revolutionize-diabetes-treatment/ XX Another study showing the blood sugar benefit of walking after a meal. Skeletal muscle plays a central role in glucose uptake. Exercise stimulates glucose transport into muscle cells through insulin-independent pathways, notably through the action of glucose transporter type 4 (GLUT-4), which is responsible for transporting glucose from blood to skeletal muscles.4 This means that even without a robust insulin response, physical activity can facilitate glucose clearance from the bloodstream. These effects also occur without requiring high-intensity exercise, making postprandial walking accessible to a broad range of individuals, including those with limited exercise tolerance. multiple studies show that starting activity within 30 minutes after a meal is optimal. https://www.news-medical.net/health/Walking-After-Meals-Small-Habit-Big-Metabolic-Gains.aspx XX Dexcom brings back Dexcom U for a 4th years.

Researchers isolated one kind of cone in the eye and aimed lasers at it to allow subjects to see a super vibrant teal shade they call “olo.”Think about the colors of the world around you—the blue of a cloudless sky, the green of a new leaf, the blazing red of a tulip's petals. We see these colors because of the way our eyes work. But what if we could change how our eyes respond to light, and present them with light in a form they'd never encounter in the natural world? What would we see?This week, researchers reported in the journal Science Advances that by using precisely aimed laser light, they were able to selectively target just one of the three types of color-sensing cones in the human retina. The cone, dubbed “M” because it responds to medium wavelengths of light, is normally stimulated at the same time as cones that respond to longer wavelength reddish light, or shorter wavelength bluish light. But after mapping the location of the cones in several subjects' eyes, the researchers were able to target just the M cones with one specific wavelength of green laser light—a condition that would never exist in nature. The result, they say, is a highly saturated bluish-green teal color unlike anything in the real world. The researchers named their new color “olo.”Study author James Fong, a computer science PhD student at University of California Berkeley, and his advisor, Dr. Ren Ng, join Host Flora Lichtman to talk about the project, and the possibility of expanding the limits of human color perception.Transcript for this story will be available after the show airs on sciencefriday.com.

durée : 00:05:22 - Avec sciences - par : Alexandre Morales - Dans un papier de la revue Science Advances, des chercheurs affirment avoir fait percevoir une nouvelle couleur à cinq personnes en stimulant leur rétine grâce à un laser.

Imagine seeing a colour so vivid, so unlike anything in nature, that your brain has no reference for it. That's exactly what happened to five people who took part in an experiment published in the journal Science Advances this week. The newly perceived colour, which is described as a hyper-saturated blue-green shade, has been named olo, and it unlocked a visual experience that was previously impossible with natural light alone. To understand the experiment, we first need to understand how we see colour. At the back of your eye lies the retina, which contains three types of photoreceptor cone cells - S, M, and L cones -each tuned to different wavelengths of light: S cones respond to short, bluish wavelengths, M cones to medium, greenish wavelengths, L cones to long, reddish wavelengths. Together, they allow your brain to mix and interpret the colours of the world around you. But here's the catch: in nature, the M and L cones are almost always activated together due to how their sensitivities overlap. This means it's essentially impossible to isolate just the M cones with regular light. As a result, a truly pure green, seen by stimulating only M cones, is something no one had ever seen - until now. The researchers used pinpoint lasers and advanced optics to stimulate individual photoreceptors in the human eye. Using a laser no more powerful than a standard green laser pointer, the team was able to target cone cells with surgical precision. First, they needed to create a cone map, a detailed image showing the exact arrangement of cone types on each participant's retina. This map allowed the system to fire microscopic pulses of light solely at the M cones, leaving the others in darkness. When volunteers looked into the laser system, they described a colour that doesn't exist in nature. Some said it was like a supercharged peacock green, others just stared in amazement. As soon as the laser was adjusted to stimulate even a few non-M cones, the olo colour vanished and was replaced instantly by the familiar green of the laser. The implications of this go far beyond a cool visual trick and open up new possibilities in both science and medicine. By allowing researchers to control cone cells at this level of precision, it may help us: Understand how colour vision truly works on a cellular level, Simulate what it's like to lose certain types of vision, helping us study degenerative eye conditions like macular degeneration, Explore how to expand human perception, possibly giving people with colour blindness access to colours they've never seen before or even enable humans to experience tetrachromacy. Sadly, most of us will never get to see olo ourselves, but its discovery is a powerful reminder of how much there is still to learn about the human body, even something as seemingly simple as colour.

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. Austin Roorda has been developing this technology using mirrors, lasers and optical devices. He is a professor of Optometry and Vision Science at University of California, Berkeley. The study was published in the journal Science Advances.Following in the footsteps of an ancient ankylosaurPaleontologists have found fossil footprints of an armoured dinosaur in the Canadian Rockies that fill in a critical gap in the fossil record. 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.

Le vieillissement du cerveau humain est un phénomène complexe, qui ne touche pas tous les individus de la même manière. Depuis plusieurs années, les scientifiques constatent que les femmes présentent généralement une meilleure résilience cognitive au fil du temps que les hommes. Elles sont souvent moins sujettes à certaines formes de déclin cognitif, et conservent plus longtemps des fonctions telles que la mémoire, l'attention ou la fluidité verbale. Mais pourquoi cette différence ? Une étude récente publiée dans Science Advances propose une explication innovante et intrigante : le rôle protecteur de certains gènes situés sur le chromosome X.Chaque être humain possède normalement deux chromosomes sexuels : les femmes ont deux chromosomes X, tandis que les hommes en ont un seul, accompagné d'un chromosome Y. Chez les femmes, l'un des deux chromosomes X est en grande partie désactivé très tôt dans le développement embryonnaire, un processus connu sous le nom d'inactivation du chromosome X. Cependant, cette nouvelle étude révèle que certains gènes longtemps restés silencieux sur ce chromosome désactivé peuvent se « réveiller » avec l'âge.Cette réactivation partielle de gènes sur le second chromosome X offrirait ainsi un "filet de sécurité" génétique aux femmes. Ces gènes réactivés joueraient un rôle protecteur contre le vieillissement cérébral, en soutenant des fonctions neuronales essentielles, en luttant contre les inflammations, ou encore en améliorant la réparation cellulaire. Les hommes, qui ne possèdent qu'un seul chromosome X, ne bénéficient pas de cette possibilité : s'il survient une mutation ou une dégradation dans un gène de leur unique chromosome X, aucun double génétique n'est là pour prendre le relais.L'étude a notamment utilisé l'imagerie cérébrale et l'analyse génétique sur un large échantillon de participants, hommes et femmes, de différents âges. Elle a montré que chez les femmes, certains gènes du chromosome X affichaient une activité accrue dans les régions du cerveau associées à la mémoire et à la cognition. Ces observations allaient de pair avec de meilleures performances aux tests cognitifs, notamment chez les femmes âgées.Ce mécanisme génétique vient compléter d'autres explications déjà avancées dans la littérature scientifique. On savait par exemple que les hormones sexuelles comme les œstrogènes jouent un rôle neuroprotecteur, surtout avant la ménopause. Les femmes ont également tendance à adopter des comportements plus protecteurs de la santé (alimentation, suivi médical, lien social), ce qui contribue aussi à leur avantage cognitif. Mais la découverte de cette « deuxième chance génétique » offerte par le chromosome X ouvre une nouvelle voie de compréhension.Cette étude souligne à quel point le sexe biologique peut influencer la trajectoire du vieillissement cérébral. Elle pourrait, à terme, inspirer des stratégies de prévention ou de traitement ciblées selon le sexe, afin de mieux protéger le cerveau humain contre les effets du temps. Hébergé par Acast.

First up this week, International News Editor David Malakoff joins host Sarah Crespi to discuss the most recent developments in U.S. science under Donald Trump's second term, from the impact of tariffs on science to the rehiring of probationary employees at the National Science Foundation.   Next, we tackle the question of extra-pair paternity in people—when marriage or birth records of parentage differ from biological parentage. Contributing Correspondent Andrew Curry writes about researchers looking into the question of how often children are genetically unrelated to their presumed fathers by using genealogy and genetic testing.   Finally, Susanne Schweizer, Scientia associate professor at the University of New South Wales, talks about her article on intrusive thoughts in the perinatal period as part of a special issue on women's health in Science Advances. Almost all pregnant and recent mothers experience intrusive thoughts about harm coming to their offspring. Schweizer and colleagues suggest gaining a better understanding of intrusive thoughts during this highly predictable window could help explain the phenomenon more broadly.   This week's episode was produced with help from Podigy.   About the Science Podcast Learn more about your ad choices.

As the new administration in the US continues to make cuts to government agencies and scientific funding, NOAA – the National Oceanic and Atmospheric Administration has been particularly trimmed. This week the professional organisation for weather forecasters – the American Meteorological Society has published a statement pleading for clemency, arguing that the whole US Weather Enterprise is at risk. It's current president elect, veteran weather broadcaster Alan Sealls describes how it's not just US weather forecasts that appear bleak.As the journal Science Advances publishes a special edition highlighting areas of women's health research, we speak with two researchers who may have found a link between menopause – or perhaps hormonal changes – and the age it occurs, with Altzeimer's Disease. Madeline Wood or the University of Toronto and Kaitlin Casaletto of UCSF describe how synaptic health – the fitness of the brain - at death seems even to be less attenuated in women who used hormonal therapy during their menopause. It is not however, yet suggested they are causally connected. But we do connect research vessel Polarstern to have an update from Autun Purser and Nottingham University's molecular biologist Liz Chakrabarti on their nearly completed voyage to the Weddel Sea, in the challengingly chilly Antarctic. They are gathering data and surveying the fauna on the sea floor below what is mostly covered in 3-4 meters of ice. The Icefish they see there are some of the only vertebrates not to have haemoglobin – nor even red blood cells – in their blood. So how, we wonder, do they actually move oxygen around their bodies? Maybe when the team publish their findings – which they are racing to do - we'll find out.Presenter: Roland Pease Producer: Alex Mansfield Production Coordinator: Jana Bennett-Holesworth(Image: National Hurricane Center Monitors Hurricane Beryl's Activity In The Caribbean.

The guests today are co-authors of a new paper in Science Advances titled: “A reassessment of the ‘hard-steps' model for the evolution of intelligent life.” Jennifer Macalady is a Professor of Geosciences at the Pennsylvania State University. Her research is focused on microbial ecology and evolution, and interactions between microorganisms and Earth materials like minerals and water through geologic time. Daniel B. Mills is a postdoctoral researcher in the Orsi Geomicrobiology Lab at The University of Munich in Germany. His research focuses on the co-evolutionary history of Earth's surface environment and eukaryotic life—a topic he approaches by studying modern marine organisms and environments. He also applies this research to the ongoing search for exoplanetary biosignatures and technosignatures. Shermer, Mills, and Macalady discuss the Hard Steps model of the evolution of intelligent life, the Drake Equation, the Fermi Paradox, the Great Filter, and the Great Silence. They also cover the Rare Earth hypothesis, major transitions in evolution, the uniqueness of humans, and the search for biosignatures and technosignatures.

Bits of Bennu have building blocks of lifeNASA's OSIRIS-REx mission took six years to travel to the asteroid Bennu and return samples to Earth. Now, the first results from the analysis of these rocks are being released. Researchers found evidence of salty water, as well as the elements necessary for life, such as amino acids and the building blocks for RNA and DNA. We spoke with Kim Tait, senior curator of mineralogy at the Royal Ontario Museum in Toronto, and co-author of one of the recent studies, published in the journal Nature.Unlocking the secret of Polar bear de-icingPolar bears spend so much time going in and out of the water that they are considered marine mammals. So when they do this in the frozen Arctic, why are they not covered in ice? A new study reveals the secret turns out to lie in the unique oils they produce that covers their white fur. Julian Carolan, a PhD candidate at Trinity College Dublin, worked with scientists in Norway, Denmark and the U.K. on this paper published in the journal Science Advances.Truffle-hunting dog finds fabulous new fungusA chance discovery has turned out to reveal a new species of North American truffle. These fungi can be desirable and valuable delicacies. An American truffle hunter, Lois Martin, and her  trained dog Monza found a distinctive truffle in a city park that turned out to be a fungus new to science. Although native to North America, it was more similar to European truffles than any found in the Americas. Dr. Greg Bonito at Michigan State University named this new truffle Tuber canirevelatum,  meaning the ‘dog-found' truffle in honour of Monza and other dogs who look for truffles. The work was published in the journal Mycologia.  Voiding your bowels can improve cognitive performanceTo maximize your cognitive function, it might be a good idea to make sure you have a poo first. That's according to a recent study in the journal Sports Medicine and Health Science. In it, scientists found that 9 out of 13 individuals improved how well they did in a mentally taxing cognitive test if they defecated first, whereas all 13 of them improved in their performance when they took a mild laxative the night before. Chia-Hua Kuo, a professor of sports medicine and nutrition at the University of Taipei, said they also saw an increase in oxygen consumption in the test subjects' subnavel regions as they were doing the test, suggesting a previously unsuspected link between the rectum and the brain. Saving species on Earth, preserving them on the moonThe world is in a biodiversity crisis. We're losing species at an unprecedented rate, thanks to climate change, habitat loss, overexploitation and more. We look at some of the more out-of-the-box solutions that are currently in the works – from creating an internet of animals to monitor biodiversity, to saving samples of Earth's biological resources on the moon.We spoke with:Martin Wikelski, the director of the Max Planck Institute of Animal Behavior, honorary professor of ornithology at the University of Konstanz, and the scientific head of the ICARUS project.Mary Hagedorn, a senior research scientist at the Smithsonian Conservation Biology Institute and senior author of a recent paper published in the journal Bioscience proposing a passive biorepository on the moon.

In this episode, the team discusses a recent scientific report concerning new evidence of hominin activity 1.9 million years ago in Graunceanu, Romania, in the form of multiple cut-marked bones. The discussion continues with exciting news from Siberia, with the discovery of a Saber-Toothed Cat cub in pristine condition, shedding new scientific light on this enigmatic species. James Chatters, PhD, then joins the team to discuss his latest paper on the Western Clovis diet, which was published in Science Advances. Dr. James Chatters earned his PhD in Anthropology from the University of Washington in 1982. He is an archaeologist and paleontologist involved in discovering and investigating many of North America's earliest human skeletons. Best known for the 1996 discovery of Kennewick Man and ongoing work at the Hoyo Negro Site in the Yucatan of Mexico, he has also done extensive work in hunter-gatherer prehistory in the western US, macroevolutionary theory, palynology, and late Pleistocene mammals, most notably ground sloths.

Ancient human ancestors didn't eat meat, and so couldn't build big brainsOne of the main reasons scientists think we became so smart is because at some point in our evolutionary past, our ancestors started eating energy-dense meat to fuel the growth of large brains. However it hasn't been clear when this started. Using a new technology, scientists were able to analyze the tooth enamel of seven 3.5 million year old Australopithecines to directly measure their meat consumption. Tina Lüdecke, from the Max Planck Institute for Chemistry, said it revealed they were primarily herbivores so meat eating would have had to come later in our evolutionary history. Their study was published in the journal Science. Building a robot bee that could one day pollinate cropsBees do an incredibly important job pollinating crops and wild plants. Now scientists in the US are trying to emulate their skills with a tiny robot bee that has all the agility and ability of the real insect. They hope eventually they can be used in indoor factory farms where real bees can't survive.  Kevin Chen, associate professor of Electrical Engineering and Computer Science at M.I.T and PhD candidate Suhan Kim were a part of this project. Their research was published in the journal Science Robotics.We are made of star stuff – but how did it get here?Elements like carbon, nitrogen and oxygen that are essential to life were forged in supernovae billions of years ago. Now new research is helping to explain how these elements – especially essential carbon – were concentrated in such a way as to be plentifully available for the chemistry of life. The study, led in part by astronomer Trystyn Berg, discovered a cosmic conveyer belt funneling carbon in and out of our galaxy over billions of years. The research was published in the Astrophysical Journal Letters.Australia's vanishingly rare marsupial mole gets a genetic checkupIn the southern desert of Australia, there lives an elusive and unique animal - the marsupial mole. It lives under the sand and is so rare that very few people have ever seen it. Scientists have now published the very first genetic research on this animal in the journal Science Advances, thanks to tissue samples donated by a local museum. Sarah Lucas is a postdoctoral research associate at the University of Münster, Germany, and was part of the team. A climate researcher makes the case for scientist-activistsThe stereotype of a scientist is a dispassionate, objective and neutral seeker of nature's truths, and many think that this makes a career in science incompatible with political activism. Canadian climate scientist Katherine Hayhoe thinks that this is a mistake. She sees her role more like that of a physician for the planet – diagnosing its ills and advocating for the health of her patient, and her patient's inhabitants. She recently co-authored a paper in the journal Nature Climate Action arguing her case.

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.

Animal aquaculture, the farming of fish, has outpaced the amount of wild-caught fish by tens of millions of metric tons each year, bringing with it negative environmental impacts and enabling abuse, says Carl Safina, an ecologist and author. On this episode of Mongabay's podcast, Safina speaks with co-host Rachel Donald about his recent Science Advances essay describing the “moral reckoning” that's required for the industry, pointing to environmental laws in the United States, which put hard limits on pollution, as examples to follow. “In the 1970s in the U.S., we had this enormous burst of environmental legislation. We got the Endangered Species Act, the Clean Air Act, the Clean Water Act, the Toxic Substances Control Act … all of these things were not because somebody invented something new. It's because we felt differently about what was important,” he says. The global fishing industry also contributes to forced labor and other worker abuses, as revealed by whistleblowers and media outlets, including Mongabay. Read our award-winning 2022 investigation, which revealed systemic abuse of foreign workers by China's offshore tuna fleet. Like this podcast? Share it with a friend, and please leave a review.

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.

In this 243rd in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we talk about the state of the world through an evolutionary lens.In this week's episode, we discuss the evidence for the traps being laid by Goliath, continuing last episode's discussion of the presidential debate. Then: sex, gender, meaning, and identity. What kind of science is being done that concludes that sex and gender are not just distinct, but unrelated? And why are 10 year olds being asked if they're transgender, or how much they feel like a boy, or a girl? While “scientists” use models to produce results that make no sense, adolescents stop pursuing meaning, which is dynamic and expands one's horizons, and instead focus on identity, which is all too-often a static dead-end.*****Our sponsors:CrowdHealth: Pay for healthcare with crowdfunding instead of insurance.
