Une étude publiée en 2026 dans la revue scientifique PNAS indique un fait surprenant, les fortes chaleurs pourraient réduire le nombre de naissances de garçons.  En analysant plus de 5 millions de naissances en Afrique subsaharienne et en Inde, des chercheurs d'Oxford ont observé que ce phénomène est dû à la fois pour des raisons biologiques et sociales. Pourquoi la chaleur impacte-t-elle plus les garçons ? Quelles sont les raisons qui expliquent ce mécanisme biologique ? Doit-on s'inquiéter de ce phénomène en France ? Écoutez la suite de cet épisode de "Maintenant Vous Savez". Un podcast Bababam Originals écrit et réalisé par Ludivine Morales.

(A note before we get into it: this article is educational, not medical advice. Talk to your doctor or a registered dietitian before making major changes to your diet — especially if you have diabetes or pre-diabetes, take blood-sugar medication, are pregnant or nursing, or are managing any chronic condition. Nothing here is intended to diagnose, treat, cure, or prevent any disease.)Research shows well-built plant-based diets usually lower blood sugar. If yours moved the other way, one of six silent glucose traps is almost always the reason — and every one of them is fixable.TLDR* The research is actually on vegetarianism's side. Large reviews of clinical trials show vegetarian and vegan diets tend to lower A1C, not raise it.* So if your numbers went up, something in how the diet was built is the real cause — not the fact that it's plant-based.* Six usual suspects: too little protein, “naked” carbs with no brakes, shrinking muscle mass, too much fermentable fiber too fast, high stress/cortisol, and late-night eating.* Each one is a fixable habit, not a reason to abandon vegetarianism.Wait — Doesn't “Plant-Based” Mean Healthier Blood Sugar?Usually, yes. When researchers actually put vegetarian diets to the test in clinical trials, the pattern is consistent: people following them tend to see their A1C go down, not up. A meta-analysis pooling multiple randomized trials found vegetarian diets were linked to a meaningful drop in A1C, and a separate meta-analysis of nine trials found a similar reduction — enough that it would be considered clinically significant by the FDA's own bar for new diabetes drugs.So if you switched to vegetarian eating and your last lab draw came back worse, I want to be straight with you: that's not the expected outcome, and it's not “just what happens” when you cut out meat. Something specific is working against you. The good news is that it's almost always one of a handful of well-understood mechanisms — and once you know which one, it's a quick fix, not a diet overhaul.Think of it like this: a car engine doesn't run worse because you switched to a different brand of gas. It runs worse because something specific — a clogged filter, bad timing, low oil — is getting in the way. Same idea here. Let's go through the six most common “clogs.”THRIVE 120 - TriplePlayDoc is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.1. The Protein Drop You Didn't NoticeThis is the single most common one. When people cut out meat, they usually don't replace that protein gram-for-gram with plant protein — they replace it with more carbs, because carbs are what fill the plate: extra rice, extra bread, extra pasta.Here's why that matters for blood sugar specifically. Protein eaten alongside carbohydrate isn't just “extra food” — it changes how your body handles the carbs. A meta-analysis of controlled feeding trials found that adding protein to a carb-containing meal meaningfully lowers the post-meal glucose spike, largely by boosting the insulin response that clears sugar out of the bloodstream faster. Pull protein out of the meal and carbs hit your blood essentially unguarded.Think of protein as the brakes on a sugar rollercoaster. Take the brakes off, and the same carbs you were eating before now send your blood sugar higher and faster than they used to.2. Naked Carbs, No BrakesThis is the same problem from a different angle: oatmeal for breakfast, a rice bowl for lunch, a smoothie for a snack. All reasonable foods — but if none of them are paired with enough protein or fat, and you're not about to go move that sugar with a workout, it hits your bloodstream as a fast, unbuffered spike. Your body answers with a bigger insulin surge, and doing that meal after meal, day after day, is exactly the pattern linked to declining insulin sensitivity over time.3. The Muscle FactorThis one surprises people: your muscles are the biggest “storage tank” for the sugar you eat. After a meal, skeletal muscle soaks up roughly 70–80% of the glucose that comes out of your bloodstream, using it to refill glycogen stores. Researchers who study this consider muscle glucose uptake the single biggest lever on whole-body insulin sensitivity.So when protein intake drops and resistance training isn't part of the picture, muscle mass tends to shrink over time — and that storage tank gets smaller. Less tank space means the same meal now leaves more sugar circulating in your blood for longer, which shows up as a slow, creeping rise in A1C.Muscle is basically your body's biggest gas tank for sugar. Shrink the tank, and the same fill-up overflows.4. High Fiber, High StressFiber itself is not the villain here — in fact, the right kind of fiber is one of the best tools for blood sugar control. Viscous, soluble fibers (found in oats, beans, and psyllium) form a gel in your gut that physically slows down how fast sugar gets absorbed, and trials show this type of fiber measurably lowers both A1C and fasting blood sugar.The issue is a different kind of fiber problem: volume and speed. Vegetarian diets are often naturally high in fermentable fiber — beans, lentils, certain grains — and when your gut bacteria break that fiber down, the fermentation process produces gas as a byproduct. Ramp up fiber intake quickly, especially the fast-fermenting kinds, and you can outpace your gut's ability to comfortably process it, leading to bloating and discomfort. That physical stress on your body, especially combined with everyday life stress, triggers cortisol release — and cortisol has a direct, well-documented job of raising blood glucose by signaling your liver to make more sugar and by making your cells less responsive to insulin.Think of fiber fermentation like a construction project in your gut. The building itself (your microbiome) benefits — but a project moving too fast kicks up a lot of dust (gas and bloating) along the way.5. Timing and Circadian RhythmsThe lifestyle shift that often comes with going vegetarian — more grazing, more small meals, more snacking — can quietly push more of your eating into the evening. That timing matters more than most people realize. Multiple studies using identical meals given at different times of day have found that the exact same meal produces a bigger blood sugar spike at night than it does in the morning, because your insulin sensitivity and beta-cell function both naturally dip in the evening. One study even found a late meal after 8pm was independently linked to worse A1C.Your body runs on a work shift for carbs. The day shift (morning, early afternoon) handles them efficiently. The night shift is running on a skeleton crew — the same carb load left unprocessed for longer, working against you while you sleep.6. Cortisol: The Common ThreadYou'll notice cortisol keeps coming up — that's not a coincidence. Cortisol's actual job during stress is to make more glucose available fast, by triggering your liver to produce it and by directly blunting how well your cells respond to insulin. Whether the stressor is emotional (a hard week at work) or physical (a gut that's working overtime to ferment more fiber than it's used to, or a body that's lost muscle mass and is struggling to regulate blood sugar as efficiently), the hormonal response is the same: more sugar released, less efficiently cleared.Who's Most Likely to Notice This?Not everyone who goes vegetarian sees their A1C move. The people most likely to notice these effects are those who already have some combination of insulin resistance, chronic stress, poor sleep, low muscle mass, or a sensitive gut. For them, a vegetarian diet doesn't cause the problem — it tends to reveal a metabolic bottleneck that was already there, quietly, underneath a different diet.This isn't a case against vegetarian eating. The clinical research is genuinely favorable toward it. It's a case for building it correctly — with enough protein, the right kind and pace of fiber, resistance training to protect muscle, and carbs eaten earlier in the day, paired with something that slows them down.Six Bottlenecks at a GlanceThe Bottom LineThe question was never really “is vegetarianism good or bad for blood sugar?” — the research says it's generally good when it's built well. The real question is: what's your body's current metabolic bottleneck? Is it protein? Muscle? Fiber pacing? Timing? Stress? Most people are dealing with one or two of these more than the others, and once you know which, the fix is usually a small, specific adjustment — not throwing out the diet.The goal isn't just to tweak what's on your plate. It's to find the actual thing standing between you and the results you were expecting when you made this change in the first place.References* Vegetarian and Vegan Dietary Patterns to Treat Adult Type 2 Diabetes: A Systematic Review and Meta-Analysis of RCTs — ScienceDirect: https://www.sciencedirect.com/science/article/pii/S2161831324001285* Vegetarian diets and glycemic control in diabetes: a systematic review and meta-analysis — PubMed: https://pubmed.ncbi.nlm.nih.gov/25414824/* The Effect of Adding Protein to a Carbohydrate Meal on Postprandial Glucose and Insulin Responses: A Systematic Review and Meta-Analysis — ScienceDirect: https://www.sciencedirect.com/science/article/pii/S0022316624003924* The Role of Skeletal Muscle Glycogen Breakdown for Regulation of Insulin Sensitivity by Exercise — Frontiers in Physiology: https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2011.00112/full* Glucose Uptake by Skeletal Muscle within the Contexts of Type 2 Diabetes and Exercise — MDPI/Nutrients: https://www.mdpi.com/2072-6643/14/3/647* Effect of viscous soluble dietary fiber on glucose and lipid metabolism in patients with T2DM: systematic review and meta-analysis — PMC: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10500602/* Dietary fiber in irritable bowel syndrome (fermentation and gas production) — PMC: https://pmc.ncbi.nlm.nih.gov/articles/PMC5548066/* Fibre, fermentation, FODMAPs and flatulence — Quadram Institute: https://quadram.ac.uk/blogs/fibre-fermentation-fodmaps-and-flatulence/* Physiology, Cortisol — StatPearls, NCBI Bookshelf: https://www.ncbi.nlm.nih.gov/books/NBK538239/* Endogenous circadian system and circadian misalignment impact glucose tolerance via separate mechanisms in humans — PNAS: https://www.pnas.org/doi/10.1073/pnas.1418955112* Impact of circadian disruption on glucose metabolism: implications for type 2 diabetes — Diabetologia/PMC: https://pmc.ncbi.nlm.nih.gov/articles/PMC7002226/* Chronotype, Chrononutrition and Glucose Tolerance Among Prediabetic Individuals (late-dinner/A1C link): https://cdn.clinicaltrials.gov/large-docs/64/NCT05163964/Prot_SAP_ICF_004.pdfTHRIVE 120 - TriplePlayDoc is a reader-supported publication.

We all want to eat healthier. The Paleo diet promises exactly that: eat like our ancestors, avoid modern foods, and improve your health. But does it really support your gut, heart and long-term health, or is the story more complicated? In this episode, Dr James Cole, a world-leading expert on prehistoric diets, joins Dr Federica Amati to explore what Paleo gets right and why some of the claims may be dangerously wrong. James explains what ancient evidence tells us about human diets, why the modern-day Paleo diet may go too far in its restrictions, and what that might mean for your heart disease risk and gut health. By the end of the episode, you'll have ideas on what principles to keep from the Paleo diet, and what rules to avoid. Could trying to eat as our ancestors did force you to cut foods your body actually needs? Before you give up grains, beans or dairy, it may be worth asking what ancient humans really ate.

I received a podcast review that basically said because a guest talked about chronic inflammation it was a "MAHA podcast." So I decided to go straight to one of the top inflammation researchers in the world and ask him directly: is chronic inflammation actually real, or is it pseudoscience?  My guest is Dr. David Furman, the Director of Stanford Medicine's 1000 Immunomes Project (the largest longitudinal study on aging and the immune system in the world) and an Associate Professor at the Buck Institute for Research on Aging, and his answer might surprise you. We play a game of Myth or Fact and bust some of the biggest inflammation claims all over the internet, from gluten and dairy to seed oils, and microplastics. We also get into how to actually test whether you're inflamed, the surprising link between chronic stress, depression, and your immune system, why your coffee habit might be doing you a favor, and exactly what to do about all of it if you have no money to spend.

We are witnessing mass social engineering and absolutely every single person on earth who has access to electronics is being manipulated no matter how awake they think they are. While X is criticized for manipulating users with the algorithm which it certainly is (not just right, but also to the left and center), Facebook has faced severe scrutiny in the past over their mind control programs, similar to MK Ultra. Facebook manipulated user news feeds in order to create compliance to issues, cause depression or cause elation. In 2014, Facebook faced controversy after it was revealed in a PNAS article titled "Experimental evidence of massive-scale emotional contagion through social networks" that the social media network used data to plant stories and ideas on timelines to make people either sad or happy based on psychological surveys on certain demographics. This experiment led to depression among some and elation among others. Facebook claimed their data use policies allowed them to do this, though they actually changed it weeks after the experiment to include "research" in their data policy. In this video, we delve into X, Facebook, mainstream media, mainstream alternative media, MK Ultra, The Tavistock Institute, culture wars and the establishment's goals. The Limited Hangouts we are witnessing in culture and media today mimic many other the experiments we saw between the 1950s and 1970s. However, today it is far more severe and the implications are far more dire as the establishment approaches the reset utilizing the new narrative. They are creating a "hive mind." Researchers and authors like David Icke have been warning about this for decades and yet most continue to fall into paradigms without a second thought because the group think feels comfortable vs "being alone" in your mindsets. Most don't want solutions. They want whatever comes easiest. Stay tuned for more from WAM!

In Part 2 of The Mechanics of Magick: Drumming, Trance, and the Brain, we follow rhythm from the sacred road into the war road and the modern machine. This episode examines war drums, military cadence, synchronized movement, crowd power, ritual physiology, propaganda, slogans, media framing, algorithmic repetition, moral-emotional contagion, and the illusory truth effect. The argument is not that rhythm is evil. The argument is that rhythm is morally flexible and powerful. It can heal, gather, strengthen, command, manipulate, or capture depending on the world built around it. The drum teaches us to hear the visible pulse first, so we can recognize the hidden drums of the modern world: the chant, the slogan, the feed, the notification loop, the soundtrack, the repeated frame, and the rhythm that trains attention before thought has time to speak.Links For The Occult Rejectshttps://linktr.ee/theoccultrejectsOccult Research Institutehttps://www.occultresearchinstitute.org/Substackhttps://substack.com/@theoccultrejects?r=7auau0&utm_campaign=profile&utm_medium=profile-pageCash Apphttps://cash.app/$theoccultrejectsVenmo@TheOccultRejectsBuy Me A Coffeebuymeacoffee.com/TheOccultRejectsPatreonhttps://www.patreon.com/TheOccultRejectsRhythm, Marching, Synchrony, and the GroupBodyMcNeill, William H. Keeping Together in Time: Dance and Drill in Human History. Cambridge, MA: Harvard University Press, 1995.Use for dance, drill, marching, synchronized movement, and “muscular bonding.” This is one of the best historical anchors for the claim that moving together in time can help bind human groups through the body. It belongs in the war drum, marching, military cadence, procession, and crowd-power material.Wiltermuth, Scott S., and Chip Heath. “Synchrony and Cooperation.” Psychological Science 20, no. 1 (2009): 1–5.Use for the claim that synchronized action can increase cooperation. This supports the argument that marching, chanting, dancing, and acting in time can alter group attachment and behavior.Hove, Michael J., and Jane L. Risen. “It's All in the Timing: Interpersonal Synchrony Increases Affiliation.” Social Cognition 27, no. 6 (2009): 949–960.Use for interpersonal synchrony and affiliation. This supports the softer social-bonding side of rhythm: people who coordinate timing can feel more connected.Tarr, Bronwyn, Jacques Launay, and Robin I. M. Dunbar. “Music and Social Bonding: ‘Self-Other' Merging and Neurohormonal Mechanisms.” Frontiers in Psychology 5 (2014): 1096.Use for music, synchrony, bonding, self-other merging, endorphins, and why rhythmic group activity can feel socially powerful. This belongs in both crowd sections and the “operator as instrument” material.Reddish, Paul, Ronald Fischer, and Joseph Bulbulia. “Let's Dance Together: Synchrony, Shared Intentionality and Cooperation.” PLOS ONE 8, no. 8 (2013): e71182.Use as extra support for synchrony and cooperation. Good optional source if you want more than Wiltermuth and Heath.Ritual Physiology, Crowd Arousal, and Collective EffervescenceKonvalinka, Ivana, Dimitris Xygalatas, Joseph Bulbulia, Uri Schjødt, Else-Marie Jegindø, Sebastian Wallot, Guy Van Orden, and Andreas Roepstorff. “Synchronized Arousal Between Performers and Related Spectators in a Fire-Walking Ritual.” Proceedings of the National Academy of Sciences 108, no. 20 (2011): 8514–8519.Use for the strongest fire-walking physiology source. This is the study showing synchronized arousal between active ritual performers and related spectators. It supports the claim that intense ritual fields can show up in bodies, not only in symbols.Xygalatas, Dimitris, Ivana Konvalinka, Joseph Bulbulia, and Andreas Roepstorff. “Quantifying Collective Effervescence: Heart-Rate Dynamics at a Fire-Walking Ritual.” Communicative & Integrative Biology 4, no. 6 (2011): 735–738.Use as a shorter interpretive companion to the PNAS fire-walking study. Good for the phrase “collective effervescence” and for explaining shared heart-rate dynamics in accessible language.Xygalatas, Dimitris. Ritual: How Seemingly Senseless Acts Make Life Worth Living. New York: Little, Brown Spark, 2022.Use for ritual, pain, synchrony, group bonding, arousal, and embodied social meaning. This is useful when moving from older ritual containers into modern crowd and spectacle.Hobson, Nicholas M., Juliana Schroeder, Jane L. Risen, Dimitris Xygalatas, and Michael Inzlicht. “The Psychology of Rituals: An Integrative Review and Process-Based Framework.” Personality and Social Psychology Review 22, no. 3 (2018): 260–284.Use for ritual as emotion regulation, performance regulation, social bonding, and formalized action. This supports the “ritual does things, it does not merely represent things” argument.War, Crowds, Mass Movements, and Collective IdentityLe Bon, Gustave. The Crowd: A Study of the Popular Mind. 1895.Use carefully. Le Bon is historically important for crowd psychology, but outdated and often elitist. Good as a historical source on crowd fear and mass suggestion, but balance it with modern social psychology.Canetti, Elias. Crowds and Power. New York: Viking Press, 1962.Use for a literary-philosophical treatment of crowds, power, command, fear, and collective bodies. Good for atmosphere and conceptual framing, not as a modern experimental source.Hoffer, Eric. The True Believer: Thoughts on the Nature of Mass Movements. New York: Harper & Brothers, 1951.Use for mass movements, fanaticism, belonging, identity, resentment, sacrifice, and the psychology of ideological devotion. Use carefully; it is sharp and useful, but not a modern empirical study.Tajfel, Henri, and John C. Turner. “An Integrative Theory of Intergroup Conflict.” In The Social Psychology of Intergroup Relations, edited by William G. Austin and Stephen Worchel, 33–47. Monterey, CA: Brooks/Cole, 1979.Use for social identity theory, in-groups, out-groups, belonging, status, and group comparison. This supports the claim that slogans and group language do not only communicate ideas; they also mark identity.Tajfel, Henri. Human Groups and Social Categories: Studies in Social Psychology. Cambridge: Cambridge University Press, 1981.Use as a broader social-identity source. Good for group belonging, categorization, prejudice, and in-group/out-group dynamics.Propaganda, Symbols, Slogans, and Mass CommunicationLasswell, Harold D. Propaganda Technique in the World War. New York: Alfred A. Knopf, 1927.Use for propaganda as symbolic management, war messaging, enemy construction, morale, and the manipulation of attitudes through stories, reports, images, rumors, and other significant symbols. This is a core Part 2 source.Lasswell, Harold D. “The Theory of Political Propaganda.” The American Political Science Review 21, no. 3 (1927): 627–631.Use for the clean definition: propaganda as the management of collective attitudes through significant symbols. This is perfect for the slogan/crowd/media rhythm sections.Ellul, Jacques. Propaganda: The Formation of Men's Attitudes. Translated by Konrad Kellen and Jean Lerner. New York: Alfred A. Knopf, 1965.Use for propaganda as a modern social technique, not merely lies. Ellul belongs in the “modern machine” argument because he treats propaganda as environmental, repetitive, social, technological, and tied to belonging.Bernays, Edward. Propaganda. New York: Horace Liveright, 1928.Use for public relations, engineered consent, mass persuasion, and the management of public opinion. Good supporting source, especially if you want advertising and PR to sit beside political propaganda.Herman, Edward S., and Noam Chomsky. Manufacturing Consent: The Political Economy of the Mass Media. New York: Pantheon Books, 1988.Use if you want a media-system critique: institutional filtering, agenda power, elite framing, and consent formation. This is useful for Part 2 but has a more political-economy angle than the rhythm/trance argument.Media Framing, Agenda-Setting, and Repeated AttentionMcCombs, Maxwell E., and Donald L. Shaw. “The Agenda-Setting Function of Mass Media.” Public Opinion Quarterly 36, no. 2 (1972): 176–187.Use for agenda-setting: media may not tell people exactly what to think, but it can influence what people think about and how important issues feel. This fits the “repetition trains attention” argument.Entman, Robert M. “Framing: Toward Clarification of a Fractured Paradigm.” Journal of Communication 43, no. 4 (1993): 51–58.Use for framing: selecting certain aspects of reality and making them more salient. This supports the section on media frames as secular ritual structures that define problems, causes, moral judgments, and remedies.Gitlin, Todd. The Whole World Is Watching: Mass Media in the Making and Unmaking of the New Left. Berkeley: University of California Press, 1980.Use if you want a historical case study on media framing and protest movements. Good optional source for how movements get shaped, simplified, or distorted by media attention.Postman, Neil. Amusing Ourselves to Death: Public Discourse in the Age of Show Business. New York: Viking Penguin, 1985.Use as cultural/media theory support for entertainment, spectacle, image, and public discourse. Useful for the “modern machine” angle, but more essayistic than experimental.Repetition, Familiarity, and the Illusory Truth EffectHasher, Lynn, David Goldstein, and Thomas Toppino. “Frequency and the Conference of Referential Validity.” Journal of Verbal Learning and Verbal Behavior 16, no. 1 (1977): 107–112.Use for the classic repetition/familiarity basis of the illusory truth effect. This supports the claim that repeated statements can gain perceived validity because they become easier and more familiar to processAlso want to remind people about the website, if you're into reading we have tons of information by multiple contributors, and we got t-shirts up on the site if you're interested.

Is a hidden molecule in your food and water silently fueling cancer, Alzheimer's, and Parkinson's? Could the supplements you trust every day be making it worse?Dr. Stephanie Seneff is a senior research scientist at MIT (published in PNAS, Frontiers, FASEB) with a career studying nutrition, biology, and toxicology. In this conversation, she explains why deuterium — a heavier form of hydrogen — may be the most underrated driver of chronic disease, why cancer might be the body's repair response to deuterium-damaged mitochondria, and why most supplements may backfire.We discuss:◾ Why deuterium may be the most important molecule you've never heard of◾ How glyphosate stops your body from clearing deuterium◾ The two supplements you should stop taking immediately◾ Why she says: "I don't believe in supplements"◾ Why chemo may be working backwards on cancer◾ How to make your gut produce low-deuterium water◾ The folic-acid-in-pregnancy and autism connection◾ Why she drinks deuterium-depleted water every dayThis is Dr. Seneff's second appearance on Live Longer World.

About a year ago an interdisciplinary tam at Oregon State invited a collection of subject matter experts for workshop on floodplain sedimentation processes.  The workshop took up a very specific question but gathering this much expertise on floodplain landforms and processes generated a wide-ranging discussion of how floodplains work, how to restore them, and even what they are.  So when Desiree Tullos reached out and invited me I brought my podcast gear in just in case… And I just found the discussions so useful that I wanted to share it with the other practitioners that have gathered around this podcast project.  We have spent a lot of time talking about channel form, function, and process on this podcast, I couldn't pass up the chance to give some time to these other, underrated, river landforms. So I asked three of the participants:  Dr. Desiree Tullos, Dr. Janine Castro and Dr. Jonathan Czuba if they'd be willing to debrief the themes and take aways from the gathering…and I think did a fantastic job replicating a lot of the value I got out of being at this workshop in this interview, with almost no prep.Desiree Tullos is a professor of Biological and Ecological Engineering at Oregon State and was one of the point people responsible for convening and imagining this workshop. Her research emphasizes sustainable engineering and management of rivers by examining the intersections of hydraulics, infrastructure, ecology, and society, and heavily emphasizes engaging and mentoring undergraduate students in research with societal relevance. Janine Castro is co-founder and Technical Director of the River Restoration Program at Portland State University and is one of the five founding members of River Restoration Northwest.  She recently retired from Federal service, where she worked as a geomorphologist for 34 years.Jon Czuba spent most of his 20 years measuring, modeling, and analyzing sediment transport across the U.S.  as a Professor of Ecological Engineering in the Department of Biological Systems Engineering at Virginia Tech.  He recently received an early career research award from the Universities Council on Water Resources for his work including publications in Science, Nature, and PNAS.This is a link to a version of the talk I gave at this workshop on floodplain modeling and processes: https://youtu.be/keGQviqInR0This series was funded by the Regional Sediment Management (RSM) program.Mike Loretto edited the first three seasons and created the theme music.Tessa Hall is editing most of Season 4.Stanford Gibson (HEC Sediment Specialist) hosts.Video shorts and other bonus content are available at the podcast website:https://www.hec.usace.army.mil/confluence/rasdocs/rastraining/latest/the-rsm-river-mechanics-podcast...but most of the supplementary videos are available on the HEC Sediment YouTube channel:https://www.youtube.com/user/stanfordgibsonIf you have guest recommendations or feedback you can reach out to me on LinkedIn or ResearchGate or fill out this recommendation and feedback form: https://forms.gle/wWJLVSEYe7S8Cd248

Una momificación de hace 14.000 años que sigue practicándose hoy en una aldea de Indonesia. El ARN de una cría de mamut congelada 50.000 años, rescatado cuando era imposible. La cara real de los europeos de hace 10.000 años. Y una roca en Marte con manchas de leopardo que puede ser la señal de vida más importante de la historia. Cuatro cartas que el tiempo no pudo borrar. Esta noche, aprendemos a leerlas. Bienvenido a Ciencia Fascinante 1x03: Lo que el tiempo no pudo borrar. ▶ EN ESTE EPISODIO: El humo que venció a 14.000 años — El equipo de Hsiao-chun Hung (Universidad Nacional de Australia) publicó en PNAS en 2025 el hallazgo más impactante de la arqueología reciente: la momificación deliberada de cuerpos humanos data de hace más de 14.000 años en el sudeste asiático. Y la misma técnica —ahumar el cuerpo de los muertos durante semanas para conservarlos— sigue practicándose hoy en el pueblo Dani de Indonesia. Catorce mil años de un gesto humano idéntico. ¿Cómo sabe la ciencia que no fue accidental? La respuesta está dentro de los propios huesos. La carta que no debía sobrevivir — Yuka es una cría de mamut lanudo que murió en la estepa siberiana hace 50.000 años. Su cuerpo lleva décadas en un museo. Pero en 2025, un equipo de Estocolmo publicó en Cell algo que la biología consideraba materialmente imposible: el ARN —la molécula mensajera que activa los genes y que se destruye en horas en condiciones normales— seguía ahí. Cincuenta mil años después. Intacto. Y decía algo. ️ El rostro que olvidamos que teníamos — Guido Barbujani, genetista de la Universidad de Ferrara, reconstruyó en pantalla la cara de un europeo de hace 10.000 años a partir de su ADN. El resultado no era lo que casi nadie esperaba: piel muy oscura, ojos azul-verdosos. Y no era una excepción. Era como éramos casi todos. La cara de Europa antes de que Europa fuera lo que creemos que siempre fue. Las manchas de leopardo de Marte — El rover Perseverance se detuvo ante una roca en el cráter Jezero y encontró un patrón de manchas oscuras con halo claro, como la piel de un leopardo. El espectrómetro reveló vivianita y greigita: dos minerales que en la Tierra casi siempre los fabrica algo vivo. Un equipo de la NASA publicó en Nature en 2025 lo que ningún científico serio dice a la ligera: es la señal más clara de vida extraterrestre hallada hasta la fecha.

In this episode of the SpearFactor Podcast, I talk with Dr. Ray Hilborn, a fisheries scientist at the University of Washington, about the state of fisheries worldwide and the real-world data behind marine conservation. Ray has spent decades studying fish populations, fishing fleets, and management systems across the globe. He walks me through what his research shows about which fisheries are healthy, which are in trouble, and what separates the two. Many of the assumptions people hold about overfishing don't match the data, and Ray explains where the gap comes from. We also get into marine protected areas. MPAs are often presented as the default tool for ocean conservation, but Ray argues the picture is more complicated. We talk about where MPAs help, where they fall short, what they cost in terms of food production and displaced fishing effort, and why catch limits, gear rules, and stock assessments often do more for fish populations than closing off areas of the ocean. Ray explains that the best way to manage fisheries is not through MPAs, but through active fisheries management and enforcement — science-based catch limits, gear restrictions, stock assessments, and monitoring. He points to his own research showing that where fisheries are managed and enforced, stocks are at target levels or rebuilding, and where management is weak, stocks decline.

Is the DMT laser experiment proof we are in a simulation? Strangers see the same alien glyphs, the code of reality. Neuroscience explains it. Almost...Is the "Code of Reality" a genuine window into a computed simulation, or merely an artifact of our brain's architecture?I deep dive into the DMT laser experiment, a $15 protocol that allegedly reveals hidden source code of our universe. I investigate why strangers independently report the same bizarre characters and geometric structures, and whether this "shared reality" unveils the Matrix or is simply a trick of our visual cortex.Topics (among others):The Code of Reality: How Danny Goler's repeatable experiment uses a 650nm red laser and DMT to induce perceptions of a high-definition hyper-structure of code.The 40,000-Year Trail: Why Paleolithic cave art, UFO glyphs, and Soviet Kozyrev Mirror experiments all feature similar geometric codes/glyphs long before the modern simulation hypothesis interpretations.Neuroscience vs. Simulation: How the Bressloff-Cowan V1 Model provides a mathematical model for why our natural brain wiring produces similar "form constants" with hallucinogens.Consider Supporting + Receive Bonus Content⁠

Depuis toujours, il naît légèrement plus de garçons que de filles chez les êtres humains. En moyenne, pour 100 filles, environ 105 garçons viennent au monde. Cette différence compense le fait que les garçons sont biologiquement un peu plus fragiles durant l'enfance.Mais aujourd'hui, certains chercheurs observent un phénomène troublant : dans plusieurs régions du monde, cette proportion semble diminuer.Et une étude publiée dans la revue scientifique PNAS suggère que le réchauffement climatique pourrait jouer un rôle inattendu dans cette évolution.Les chercheurs de l'Université d'Oxford ont analysé plus de cinq millions de naissances sur plusieurs décennies. Leur objectif : comprendre comment les températures influencent le sexe des bébés à la naissance.Le résultat est frappant.Lorsque les températures dépassent environ 20 °C pendant des périodes prolongées, la proportion de garçons diminue significativement.Autrement dit : plus il fait chaud, moins il naît de garçons.Mais pourquoi ?La clé se trouve probablement dans la fragilité biologique des fœtus masculins.Dès les premières semaines de grossesse, les embryons mâles semblent plus vulnérables aux stress environnementaux : pollution, malnutrition, catastrophes naturelles… et désormais chaleur extrême. Les scientifiques pensent que le stress thermique pourrait augmenter les risques de fausses couches spontanées touchant davantage les fœtus masculins.Car porter un enfant représente déjà un immense effort physiologique pour l'organisme maternel. Or la chaleur ajoute un stress supplémentaire : déshydratation, inflammation, perturbation hormonale, augmentation du cortisol — l'hormone du stress.Et les embryons masculins résisteraient moins bien à ces conditions difficiles.Ce phénomène avait déjà été observé après certains événements extrêmes. Après des canicules, des famines ou des catastrophes naturelles, plusieurs pays avaient enregistré temporairement moins de naissances masculines.Mais l'étude d'Oxford est l'une des plus vastes jamais réalisées sur le sujet, et elle renforce l'idée que le climat pourrait influencer directement la composition démographique humaine.Attention toutefois : il ne s'agit pas d'une disparition massive des garçons. Le phénomène reste modéré. Mais à l'échelle de populations entières et sur plusieurs décennies, ces variations deviennent statistiquement très importantes.Les chercheurs soulignent aussi qu'il pourrait exister d'autres facteurs liés au réchauffement climatique : pollution atmosphérique accrue, perturbateurs endocriniens ou modification des conditions de vie.Cette découverte rappelle surtout une chose fascinante : le changement climatique n'affecte pas seulement les glaciers, les océans ou les forêts.Il pourrait aussi agir silencieusement sur la biologie humaine elle-même.Jusqu'à influencer, peut-être, le sexe des enfants qui naîtront demain.

Welcome back to Scaling Theory. In this episode, I speak with Matthew O. Jackson, the William D. Eberle Professor of Economics at Stanford University and an external faculty member at the Santa Fe Institute. Matthew is one of the founders of the modern economics of networks and the author of The Human Network and Social and Economic Networks.We talk about the friendship paradox, why homophily slows how fast a society learns the truth but helps niche ideas catch fire, and the gossip study where villagers in southern India proved remarkably good at naming the most central spreaders in their community. We then turn to AI agents as a different species: Turing tests on LLMs, the steerability of agent personas through system prompts, and what to make of Moltbook, the social network for AI agents.By the end, you will know why telling students how much their peers actually drink reduces binge drinking more than warning them about the dangers of alcohol, why the same network can spread a virus quickly and a belief slowly, and why AI agents change their behavior when asked to explain it.Papers and works referenced in the conversationBooksThe Human Network: How Your Social Position Determines Your Power, Beliefs, and Behaviors — Matthew O.

Something's not right in the woods, at least if you're a white-tailed deer. In this episode, the guys dig into chronic wasting disease (CWD), a strange illness reshaping deer populations in many areas of the Lower 48 (and Scandinavia!). It's not caused by a virus or a bacteria, but it is related to mad cow disease. They break down what it is, how it spreads, what's happening inside infected animals, and why it's so dang hard to contain. The deer are not alright… and there's a reason.This episode was recorded on April 23, 2026 at Walton Woods Park in Amherst, NY (a suburb of Buffalo). Episode Notes and Links· Are there different CWD strains in a single animal? Chronic wasting disease isn't a single, uniform pathogen. It's more like a shifting swarm. Infected deer can carry multiple prion “strains” at once, meaning different misfolded shapes of the same protein that behave in slightly different ways. They could spread through the body differently, build up in different tissues, and cause disease at different rates. Lab experiments show this most clearly: when CWD prions are passed through model systems, what looks like one strain can split into multiple distinct variants, or reveal that a mixed population was there all along (e.g., Angers et al. 2010 PNAS; Béringue et al. 2012 Journal of Virology; Li et al. 2010 Journal of Virology). In actual deer, the picture is harder to pin down, but studies comparing prions from different tissues and individuals show real strain diversity and suggest that more than one strain can exist within a single animal (e.g., Angers et al. 2009 Journal of Virology; Moore et al. 2016 Emerging Infectious Diseases). The takeaway is that CWD behaves less like a single disease agent and more like a moving target: a cloud of protein shapes, some dominant, some hidden in the background, that can shift over time, giving the disease more chances to adapt, persist, and potentially jump into new hosts.· Does repeated exposure to CWD reduce incubation time in deer? Repeated exposure to CWD prions does likely shortens incubation time, mainly because prion diseases are strongly dose-dependent. Higher cumulative exposure, whether from a single large dose or many smaller ones over time, can both increase the chance of infection and accelerate disease progression. Experimental studies in deer and elk show that animals exposed to higher or repeated doses tend to develop symptoms faster than those exposed once at low levels. In the wild, this likely plays out through repeated contact with contaminated environments like soil, plants, and carcass sites. That said, factors like genetics and prion strain can still influence how quickly the disease develops in any given animal.· Is CWD the only prion disease that affects wildlife? CWD is the only prion disease currently thriving as a self-sustaining epidemic in wild populations. The others mostly sit at the edges and are livestock diseases that occasionally spill into wildlife or appear in captive/wild interface cases. For example, scrapie occasionally “leaks” into the wild (it has been found in bighorn sheep), but it doesn't take over. It flickers at the edges of livestock systems. Nothing like the landscape-level, self-sustaining spread we see with CWD. That's what makes CWD so concerning: it's not just present in wildlife, it seems to be built for it.· Steve talked about the possibility of vampire bats and wild hogs spreading CWD. What's the story? There's currently no evidence that vampire bats are spreading CWD, but the wild hog story has gotten more interesting recently. Blood-feeding bats like the Common Vampire Bat (Desmodus rotundus) are often mentioned because prions can occur in blood at low levels, but there are no peer-reviewed studies showing bat-mediated transmission, nor any field patterns linking bats to CWD spread. So the bat idea remains speculative. Wild hogs (Sus scrofa), on the other hand, have moved beyond pure theory. A recent peer-reviewed study (e.g., Soto et al. 2025 Emerging Infectious Diseases) detected low levels of CWD prion activity in free-ranging pigs in endemic areas, suggesting they can pick up and carry prions after scavenging infected carcasses. Combine this with earlier work showing prions can survive digestion and still remain infectious (e.g., Nichols et al. 2009 PLoS ONE), it all points to hogs as plausible mechanical vectors: in other words, organisms that can move infectious material without necessarily developing the disease themselves. The takeaway: vampire bats are still a biologically interesting but unsupported idea, while wild hogs are emerging as potential “messy middlemen,” capable of redistributing prions across the landscape, even if they're not a primary engine of CWD transmission, which is still driven by deer-to-deer contact and long-lived environmental contamination.· Why doesn't NYS do more free testing?New York doesn't offer broad, free testing for every deer. Not because it's ignoring CWD, but because it uses a more targeted, strategic approach. There are a few key constraints on broad, free testing:Cost & logistics: Each test isn't just a swab. It involves lab processing (often PCR or amplification assays), trained staff, and sample handling. Scaling that to hundreds of thousands of deer is a major lift.Low prevalence (right now): When disease prevalence is near zero, mass testing tends to return very few positives, so agencies prioritize early detection in hotspots instead.Management strategy: Agencies often invest more in prevention (carcass transport rules, feeding bans, education) than broad surveillance.Hunter participation: “Free for all” testing can overwhelm systems unless tightly managed, and many states have learned that targeted programs get better data per dollar.So NYS is focusing its efforts on where they see it mattering most: high-risk areas, roadkills, sick/dead deer, and zones near known outbreaks—because testing every hunter-harvested deer statewide would be extremely expensive for relatively low yield in a state with no established CWD population.More info on NY's response, as well as what's happening nationally:The NYS Department of Environmental Conservation's page on CWD (including information on how you can help, scroll down to “Members of the Public”)CWD in Captive Deer: DEC's Response in 2024Chronic Wasting Disease Detection and Management: What Has Worked and What Has Not?

Hey Tinnitus Friends & Family, A new study from Oregon Health & Science University found a direct brain circuit linking serotonin to tinnitus symptoms. If you're taking antidepressants and have tinnitus, you've probably seen the headlines—and maybe felt some panic. Here's the truth: this is good science, not a reason to stop your medication. In this video, I break down what the research actually found, why mouse studies can't tell the whole story, and what this means if you're currently taking SSRIs. I also share my personal experience—I take SSRIs myself, and they haven't worsened my tinnitus. **Key Takeaways:** ✅ The study found a serotonin → auditory circuit that can create tinnitus-like behavior in mice ✅ This validates what some people report, but doesn't mean SSRIs "cause" tinnitus ✅ SSRIs can be life-changing for depression and anxiety—the benefits often far outweigh risks ✅ Never stop medication without talking to your doctor ✅ Habituation works regardless of whether you're on medication **Timestamps:** 0:00 Introduction: Who I Am (and Who I'm Not) 1:15 Why This Research Matters 2:20 What Are SSRIs? 3:40 The Study Explained: Serotonin → Auditory Circuit 5:10 How the Research Was Done (Optogenetics) 6:30 What Dr. Trussell Said About Future Treatments 7:45 My Take: What This Means for YOU 9:20 My Personal Experience with SSRIs 10:15 Bottom Line: Talk to Your Doctor 11:00 You Don't Have to Do This Alone **Resources Mentioned:**

On le sait intuitivement : certaines relations nous épuisent. Mais ce que la science révèle aujourd'hui va beaucoup plus loin. Certaines personnes de notre entourage pourraient littéralement accélérer notre vieillissement biologique.Une étude publiée le 22 janvier 2026 dans la prestigieuse revue PNAS, menée par des sociologues et spécialistes du vieillissement issus de plusieurs universités américaines, apporte des résultats frappants. Les chercheurs se sont intéressés à ce qu'ils appellent les “hasslers” : des individus qui génèrent du stress, des conflits ou rendent la vie plus difficile au quotidien.Leur conclusion est claire : ces relations négatives ne sont pas seulement désagréables, elles agissent comme de véritables accélérateurs du vieillissement.Pour le démontrer, les chercheurs ont analysé plus de 2 000 adultes, en combinant questionnaires sociaux et analyses biologiques à partir d'échantillons de salive. Grâce à des outils très avancés, ils ont mesuré l'âge biologique des participants, c'est-à-dire l'état réel de leurs cellules, indépendamment de leur âge chronologique.Et les résultats sont impressionnants.Chaque personne “toxique” supplémentaire dans l'entourage est associée à une augmentation d'environ 1,5 % du rythme de vieillissement. Concrètement, cela correspond à environ neuf mois de vieillissement biologique en plus.Pourquoi un tel effet ?Parce que ces relations agissent comme des sources de stress chronique. Or, le stress prolongé entraîne une cascade de réactions dans l'organisme : augmentation du cortisol, inflammation persistante, affaiblissement du système immunitaire. À long terme, ces mécanismes accélèrent l'usure du corps.Autrement dit, ces interactions négatives “passent sous la peau”. Elles modifient réellement notre fonctionnement biologique.L'étude montre aussi que ces relations ne sont pas rares. Près de 30 % des individus déclarent avoir au moins une personne de ce type dans leur entourage.Fait intéressant, toutes les relations négatives n'ont pas le même impact. Les tensions avec la famille ou certaines connaissances semblent plus délétères que celles avec un conjoint, probablement parce qu'elles sont plus difficiles à réguler ou à éviter.Ce que cette recherche met en lumière, c'est une idée essentielle : notre santé ne dépend pas uniquement de ce que nous mangeons ou de notre activité physique. Elle dépend aussi, profondément, de la qualité de nos relations.Au fond, bien s'entourer n'est pas seulement une question de bien-être émotionnel. C'est aussi, très concrètement, une question de longévité. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

How does something living emerge from something that isn't?  In this episode, Lee Cronin pushes the question back even further: before cells, before DNA, before biology as we usually think of it, what kind of process could make matter start organizing itself into something alive? He and Michael Shermer get into assembly theory, RNA, autocatalysis, and the deeper puzzle of whether causation and selection may already be at work long before the first organism appears. The conversation also branches into consciousness, free will, and the possibility that life may be widespread in the universe, even if it looks nothing like life on Earth. Lee Cronin is Regius Professor of Chemistry at the University of Glasgow, Scotland, where he leads one of the world's largest multidisciplinary chemistry research groups. He has raised more than $35 million in grant funding, with current research income of $15 million, and has authored more than 350 peer-reviewed papers, including recent work published in Nature, Science, and PNAS. He and his team are trying to make artificial life forms, find alien life, explore the digitization of chemistry, understand how information can be encoded into chemicals and construct chemical computers.

Extinction Rebellion's co-founder Clare Farrell and conservation scientist Dr Charlie Gardner team up once more to discuss issues and stories they feel are not getting enough airtime. They want to make sure that the latest news in science and important reports that are relevant to the climate and ecological crisis are flagged and explained in ways that are easy to understand.EPISODE 31: Biodiversity: suppressed report, finance gap, grassroot's protection, and Hannah SpencerIn this episode Clare and Charlie examine a censored UK intelligence assessment on biodiversity breakdown, the economic system driving ecosystem destruction, and the role of people power in protecting the planet. They also discuss what a surprising Green Party by-election victory might mean for climate politics.REFERENCESITV coverage of suppressed biodiversity national security reporthttps://www.youtube.com/watch?v=59DZiPdsOc8IPBES Business and Biodiversity Assessmenthttps://www.ipbes.net/bba-report/media-releaseRole of social movements in conserving nature New paper in PNAS based on Environmental Justice Atlashttps://www.pnas.org/doi/epdf/10.1073/pnas.2513327123NB the views in this show are Clare and Charlie's own and do not necessarily reflect the official position of Extinction Rebellion.---------------------Please, share, comment, subscribe, like, mobilise, and donate! https://chuffed.org/xr/ukExtinction Rebellion UK: https://extinctionrebellion.uk/

What does it truly take to change what we do — for yourself and at scale, sustainably in the real world?In this episode, Angela sits down with Hengchen Dai, Associate Professor at UCLA Anderson and co-director of the UCLA Nudge Unit, to explore the science behind why people do what they do, and what it takes to shift it.Hengchen brings rigorous academic research published in Nature and other notable publications, and field experiments run inside hospitals, university health systems, and national pharmacy chains with millions of participants. What emerges is a practical toolkit for anyone trying to create lasting change — whether you're a leader, a clinician, a policymaker, or just someone trying to get better at your own habits.Key Takeaways  -  Behaviour change is not one-size-fits-all — someone who skipped their flu shot this year (but got it last year) has a completely different barrier (forgetting, procrastination) than someone who has never been vaccinated (belief, scepticism). Targeting interventions based on past behaviour dramatically improves results.

A new PNAS study found that the people who chronically stress you out don't just ruin your mood — they accelerate your biological aging. AJ and Johnny break down the research showing that each “Hassler” in your close network is linked to faster cellular aging, measurable at the DNA level. The real threat to your health isn't isolation — it's tolerating the wrong people.

Why do some conversations feel effortless — while others fall flat even when you said nothing wrong? AJ and Johnny break down the neuroscience of “clicking,” including a 2022 PNAS study showing that connection often comes down to milliseconds. The secret isn't better stories or smarter answers — it's timing. Shorter response gaps signal attunement, alignment, and shared rhythm. Longer gaps quietly erode chemistry. If you've ever felt “off” despite saying the right things, this episode explains why — and how timing becomes social body language. 00:00 – The gap you can feel01:00 – Why chemistry isn't personality02:00 – The PNAS timing study03:15 – Same words, different timing04:15 – Why rhythm equals connection Stop being over looked and unlock your X-Factor today at ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠unlockyourxfactor.com⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ Check out Johnny on ⁠⁠⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠@Social_Intell⁠⁠⁠⁠⁠⁠⁠⁠⁠ or on ⁠⁠⁠⁠⁠⁠⁠⁠⁠Tiktok @social_intel⁠⁠⁠⁠⁠⁠⁠⁠⁠  The very qualities that make you exceptional in your field are working against you socially.  Visit the ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠artofcharm.com/intel ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠for a social intelligence assessment and discover exactly what's holding you back.
