A Little Bit Of Science

A 1960s mouse utopia that collapsed into a vanity-obsessed apocalypse, a global database of 150,000 enthusiastic stool photos, and a scientific quest to help humans regrow limbs like a salamander. This week, we bounce between rodent dystopias, AI-powered gut tracking, regenerating toes, and international idioms for absolute chaos. We start in the late 1960s with Universe 25, an experiment that gave mice everything they wanted and accidentally proved that absolute perfection leads to a total social meltdown and a faction of self-obsessed, grooming-addicted rodents. Then, shifting gears with a violent jerk, we check in on a health app that has amassed a staggering database of 150,000 human poo images to train AI to analyse gut health. From there, we look to the future, where scientists are trying to steal a trick from the salamander to see if mice and eventually humans can regrow missing limbs. And to end the episode, we take a quick detour into international linguistics to look at how different cultures describe things going completely wrong, from Swedish blue cupboards to vivid Brazilian panic.   CHAPTERS: 00:00 Introduction 02:20 Why Universe 25 Happened 04:58 Building Mousetopia 08:43 Utopia Turns Violent 11:53 Behavioural Sink Theory 14:04 Misuse And Critiques 18:45 Poop App Citizen Science 24:58 Sharing Stool Online 25:44 Selling Poo Data 27:25 AI Data Hunger 28:23 Elvis Toilet Death 29:43 Constipation Studies 35:02 Mouse Toe Regrowth 41:17 Cactus And Sayings   SOURCES: https://www.404media.co/ai-poop-analysis-app-offered-to-sell-me-access-to-its-users-poops/?ref=daily-stories-newsletter https://www.nature.com/articles/s41467-026-72066-8 https://bsky.app/profile/adamcsharp.bsky.social/post/3mlqozoour22z https://theconversation.com/constipation-increases-your-risk-of-a-heart-attack-new-study-finds-and-not-just-on-the-toilet-237209 https://www.mamamia.com.au/elvis-constipation/ https://www.nature.com/articles/s41598-023-38068-y https://pubmed.ncbi.nlm.nih.gov/32873621/ https://www.theguardian.com/science/2024/nov/21/the-mad-egghead-who-built-a-mouse-utopia-john-b-calhoun See omnystudio.com/listener for privacy information.

This week we have hippos with hidden bits, hearts that take a mechanical detour, and a medical case study that will make you sit down and reconsider every life choice that led you to having a body. It is science at its best and worst, fascinating, useful, and deeply inconvenient. We start at the zoo, where hippo castration is a real population control tool, partly to manage breeding and partly to reduce aggression. The catch is hippo anatomy is not built for human convenience, with internal testes that turn the whole procedure into a high stakes game of hide and seek inside a very large, very grumpy animal. Then we move from hippos to hearts, looking at cardiac surgeries that use a heart lung bypass machine. Some patients report a temporary cognitive dip afterward, often called pump brain, and nobody is fully sure why it happens. It might be the machine, the stress of surgery, or subtle changes in blood flow and inflammation, but the mystery is still very much alive. Finally, we end with a story that makes every listener cross their legs in sympathy. A man developed a rectal urethral fistula after previous surgery, likely linked to a catheter complication during a coma, and his internal plumbing rerouted itself in the most unhelpful way possible. The takeaway is simple. Bodies are fragile, embarrassment is useless, and if something feels wrong, get it checked.

Winter Olympians are allegedly gaming their suit seams for extra lift, the ocean is still capable of throwing an absolutely giant wall of water at your face with no warning, and somewhere in Queensland, a blob of pitch is taking nearly a century to prove it is technically a liquid. This week, we bounce from sports cheating to monster waves to the slowest experiment on Earth, with science doing what it does best and refusing to be tidy. We dig into ski jumping and the art of the tiny advantage, including why the groin region has become an unexpectedly important battleground in Olympic aerodynamics. Then we hit the open ocean, where rogue waves have gone from sailor myth to measured reality, and the scariest part is how suddenly they show up. From there, climate change delivers a curveball in Svalbard, where some polar bears are getting fatter by adapting their diets and hunting patterns. We also look at 3D printable electronic skin that lets robots feel touch, and a massive Swedish study that challenges long-held assumptions about autism and gender bias. Finally, we pay tribute to the pitch drop experiment at the University of Queensland, a reminder that some scientists are built differently and will happily wait decades for goo to make a point.  CHAPTERS:    00:00 Winter Olympics Excitement 00:19 The Science of Ski Jumping Suits 01:25 Meet the Hosts 02:18 Ski Jumping Suit Scandal 10:13 Polar Bears and Climate Change 16:21 Rogue Waves: The Ocean's Hidden Danger 29:04 The Mystery of the Unsinkable Ship 29:24 The Rise of Rogue Waves 29:42 The Record-Breaking Youclue Lit Wave 30:41 Super Rogue Waves: A New Threat? 32:08 The Physics of Waves 34:06 3D Printable E-Flesh: A Technological Marvel 38:28 Autism: A Gender Perspective 45:27 The Pitch Drop Experiment: A Slow Burn 55:41 Mailbag and Final Thoughts   SOURCES: https://www.aps.org/apsnews/2018/01/existence-rogue-waves https://www.abc.net.au/news/2022-12-04/rogue-wave-kills-us-passenger-on-antarctic-cruise/101731482 https://www.sciencealert.com/gigantic-wave-in-the-pacific-was-the-most-extreme-rogue-wave-on-record https://www.nytimes.com/2021/04/21/science/beal-seeds-experiment.html https://magazine.wfu.edu/2022/10/05/unearthing-time-in-a-bottle/ https://www.sciencealert.com/the-worlds-longest-running-lab-experiment-is-almost-100-years-old? https://www.guinnessworldrecords.com/world-records/longest-running-laboratory-experiment https://www.mentalfloss.com/article/85986/15-longest-running-scientific-studies-history https://www.bbc.com/news/science-environment-28402709 https://www.sciencenews.org/article/oldest-pitch-drop-experiment https://www.theguardian.com/sport/2026/feb/05/penis-injection-doping-claims-in-winter-olympics-ski-jumping-investigated-by-wada Scientists share design so you can make your own 3D-printable 'eFlesh' for robots — affordable,easy to produce, and highly-tactile robot sensor grips can be printed at home Towards the equal recognition of autism in girls and women Body condition among Svalbard Polar bears Ursus maritimus during a period of rapid loss of seaice  See omnystudio.com/listener for privacy information.

Everyone wants to live forever, dogs are out here doing actual jobs, and someone has tried to work out where heaven might be using astronomy. We dig into the strange science of longevity, including research suggesting reproduction and lifespan might be linked in uncomfortable ways. Then they meet the working dogs sniffing out invasive species, guarding airport runways, and generally making the rest of us look lazy. From there, things get cosmic. An opinion piece argues heaven could sit beyond our cosmic horizon, which is a great way to accidentally spend your afternoon thinking about infinity. There is also a quick detour into gelatin-based culinary chaos, featuring the kind of vintage recipes that should come with a warning label. We wrap up with listener stories, including a cow named Veronica who can use a broom as a tool, because of course she can.   CHAPTERS: 00:00 Introduction  00:19 Exploring the Science of Longevity 01:00 Psychology and Climate Action 01:09 Mailbag and Birthday Surprise 01:27 Lifestyle Changes for Longevity 02:47 Reproduction and Longevity 12:58 Dogs with Jobs 21:07 Science Finds Heaven 27:51 Cosmic Horizon and Hubble's Law 29:39 Einstein's Relativity and Speed of Light 31:18 The Mysteries Beyond the Cosmic Horizon 40:49 Veronica the Tool-Using Cow 48:03 Gelatin: A Culinary and Industrial Marvel 54:58 Komodo Dragons and Asexual Reproduction 56:25 Listener Mailbag and Fun Facts       SOURCES:   https://www.sciencedirect.com/science/article/abs/pii/S0092656622000423 https://futurism.com/health-medicine/conspiracy-theories-psychology https://www.sciencedirect.com/science/article/abs/pii/S0092656622000423 https://futurism.com/health-medicine/men-lifespan-castration https://www.eurekalert.org/news-releases/1109009 https://www.aol.com/articles/heaven-real-science-may-reveal-130016778.html https://michaelguillen.com https://www.iflscience.com/we-didnt-even-think-about-looking-broom-wielding-veronika-shows-tool-use-in-cows-isnt-so-absurd-after-all-82260 https://pmc.ncbi.nlm.nih.gov/articles/PMC9963746/ https://www.nature.com/news/2006/061218/full/news061218-7.html https://www.rspcaqld.org.au/blog/trending-now/dogs-with-unusual-jobs https://www.usatoday.com/story/life/health-wellness/2024/04/05/schizophrenia-hallucinationspsychiatric-assistance-dog/73171229007/ https://www.anthropocenemagazine.org/2026/01/people-like-the-idea-of-being-green-but-they-hate-being-told-what-to-do-even-more/See omnystudio.com/listener for privacy information.

AI is giving people a confidence boost they might not deserve, especially among those who consider themselves tech-savvy. Studies show that using AI for problem-solving leads many to overestimate their own abilities, with higher AI literacy actually making users more likely to trust the machine and question themselves less. The smarter we think we are with technology, the more likely we are to fall for its digital flattery. Meanwhile, ancient Australia was home to predators that make today’s wildlife look tame. Fossil evidence suggests that five-metre crocodiles once hunted by dropping out of trees onto unsuspecting prey. This twist on the classic crocodile encounter adds a new layer of terror to Australia’s already legendary roster of dangerous animals. Forget snakes in the grass. Sometimes the real threat was lurking above. On the cultural front, Gen Z is challenging old standards and rewriting the rules on everything from ironing to mental health. Some in this generation long for a less digital era, question the value of traditional skills, and proudly reject the notion that neat clothes equal good character. They also claim credit for baggy jeans and even admit to being the most annoying generation to work with. From digital delusions to tree-dwelling crocs and Gen Z’s new priorities, the only thing we can count on is that the world refuses to stay boring.   CHAPTERS: 00:00 Introduction  00:48 AI and the Dunning-Kruger Effect 02:11 AI Literacy and Overconfidence 02:51 AI's Impact on Self-Assessment 06:59 Australian Wildlife and Myths 07:35 Legend of the Drop Croc 08:57 Generational Differences 10:10 Gen Z's Perspective 11:03 Skills and Inventions 12:52 Annoying Generations at Work 13:40 Conclusion and Call to Action   SOURCES: AI Is Causing a Grim New Twist on the Dunning-Kruger Effect Generation Conflicted: How Do Gen Zers Compare Themselves to Past Generations?

A ventriloquist once ruled the radio waves, captivating millions with stage tricks that made no visual sense but somehow worked perfectly through a speaker. The world’s love for a good illusion runs deep, stretching from ancient oracles channeling voices through their bellies to audiences mesmerised by dummies with invisible lips. Humans have always been drawn to spectacle, even when it requires a leap of imagination. The world of competitive chestnut-smashing, known in England as Conkers, has moved far beyond childhood nostalgia. Now it is a battleground for grown-up pride, world championships and the occasional controversy. When the stakes are glory and bragging rights, even a simple game can become the centre of suspicion and scandal. Even stone skimming is not immune to drama. The World Stone Skimming Championships recently faced its own rule-bending episode, with contestants trying to perfect their throws in shady ways that organisers had to address. Whether it’s radio dummies, nut-bashing or stone skipping, humans will always find a way to turn even the silliest competition into a drama.   CHAPTERS: 00:00 Introduction  02:27 The Curious Case of Radio Ventriloquism 05:18 King of Conkers Controversy  08:53 Stone Skimming Championships and Cheating Scandals 12:18 Conclusion and Listener Engagement SOURCES: Cheating scandal rocks world stone skimming championships ‘King Conker’ cleared of cheating at World Conker Championships The Edgar Bergen and Charlie McCarthy ShowSee omnystudio.com/listener for privacy information.

A Rome-based research team discovered poetry can jailbreak AI systems by bypassing safety filters that normal prompts can't crack, making verse a genuine cybersecurity vulnerability. Medieval physicians believed flatulent foods like beans and onions were aphrodisiacs because intestinal gas supposedly enhanced sexual performance, Palmer Luckey, the tech billionaire behind Oculus, now advocates for submarines that tunnel through Earth's crust for national defense, while a Dublin man contracted penile tuberculosis from working with deer in a rarely documented case of genital TB. Poetry defeats AI security by exploiting how language models process poetic structure, proving Aristotle's warnings about poets in governance were surprisingly futuristic. Medieval fart-based aphrodisiacs never worked but show humanity's eternal optimism for simple bedroom solutions, while Luckey's crust-submarine idea sounds insane until you remember he actually made VR mainstream. The Dublin TB case demonstrates that tuberculosis can infect any body part and that working with animals carries risks nobody considers - including your genitals contracting lung diseases. The biggest threats to AI are poets, the worst aphrodisiacs involved intestinal wind, crust submarines might actually happen, and deer can give you dick tuberculosis. Science is weird, history is weirder, and Palmer Luckey wants to make it weirder still.   CHAPTERS: 00:00 Introduction 02:07 Plato's Republic and AI Poetry 03:54 The Power of Poetry in AI 07:59 Historical Aphrodisiacs and Fertility 19:01 Simultaneous Orgasms and Farting 19:36 Windy Meats and Fertility Myths 24:19 Palmer Luckey and Virtual Reality 31:00 Penile Tuberculosis: A Rare Case 36:50 Smart Toilets and Privacy Concerns SOURCES: ‘End-to-end encrypted’ smart toilet camera is not actually end-to-end encrypted Scientists Discover “Universal” Jailbreak for Nearly Every AI, and the Way It Works Will Hurt Your Brain Adversarial Poetry as a Universal Single-Turn Jailbreak Mechanism in Large Language Models Palmer Luckey on the Future of Warfare Beans, ale & 'windy meats': surprising 17th-century aphrodisiac When Beans were the Food of Lust Why you don’t want to get tuberculosis on your penisSee omnystudio.com/listener for privacy information.

Horseshoe theory proposes that political extremes loop back around until far-left and far-right ideologies find disturbing common ground, sharing authoritarian tactics, propaganda methods, and contempt for democratic norms despite claiming opposite values.  Scientists are using AI to decode brain activity and caption your thoughts, raising serious questions about privacy and future thought-policing. The technology has remarkable potential for medical applications like helping locked-in patients communicate, but it's also concerning for policing applications where authorities might claim to know what you're thinking even when the AI is wildly guessing. Despite frankly not-so-great accuracy, it sets us on a path toward the dystopian surveillance that sci-fi has warned about for decades. Your fingers and toes developed from genetic blueprints originally designed for a fish's cloaca, meaning your hands evolved from ancient fish butt architecture through evolution's tendency to repurpose existing solutions. Your ability to type, paint, play piano or give someone the finger exists because millions of years ago evolution looked at fish butt genes and decided to work with them.  Harry Whitaker's attempt to collect every element from the periodic table ended with police at his door after he stockpiled explosives and radioactive materials, proving that even well-intentioned scientific curiosity needs tempering before it crosses into illegal weapons manufacturing.
