  • DARK vs LIGHT

    DARK vs LIGHT
    2026/05/17
    Why are black cars more dangerous, white chess pieces more successful, and pandas apparently incapable of coping with minor inconvenience? Professor Hannah Fry and Michael Stevens (VSauce) unpack one deceptively simple question - which would win in a fight between black and white? - and end up exploring everything from colour psychology and radioactive frogs to quasars, fantasy literature, and whether the universe itself ultimately sides with darkness. Along the way, Hannah invents a new category of “cool cult members,” Michael explains how light could theoretically form a black hole, and both attempt to avoid turning the entire episode into a Tolkien podcast. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  • Polymetalic Nodules Are Weird

    Polymetalic Nodules Are Weird
    2026/05/13
    What if one of the most valuable objects on Earth has been sitting untouched at the bottom of the ocean for 100 million years? In this Field Notes episode, Professor Hannah Fry brings Michael Stevens (VSauce) a strange metallic rock formed in the deepest parts of the Atlantic over millions of years. What begins with a bizarre Cold War CIA cover story involving Howard Hughes and a sunken Soviet submarine quickly turns into a journey through deep sea geology, natural “electric” rocks, and the environmental dilemma of mining the ocean floor for the rare metals used in electric car batteries. Plus: can you train yourself to become ambidextrous? are giraffes more vulnerable to lightning strikes than other animals? Does damp cold really feel colder than dry cold? And do humans actually sense wetness at all? ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    "A Grim Enemy For Reasons We Do Not Yet Comprehend"
    2026/05/11
    * This episode contains descriptions of warfare and use of chemical weapons * How do you feed a world that’s running out of food? In this episode of The Rest Is Science, Hannah Fry and Michael Stevens uncover one of the strangest and most unsettling stories in modern science: the tale of the man who learned how to pull fertiliser out of thin air. This discovery transformed agriculture. It made modern civilisation possible. But it also powered explosives, prolonged the First World War, and helped to birth some of the most deadly chemical weapons in history. From battles for bird poop and to the ethics of scientific progress, this is the story of the molecule that changed humanity forever. ------------------ For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  • When 0 = 1000

    When 0 = 1000
    2026/05/06
    Why does one of the most familiar numbers on a nutrition label turn out to be far more complicated than it looks? What can a can of fizzy drink teach us about thermodynamics, human metabolism, and the strange ways scientists measure energy? Professor Hannah Fry and VSauce’s Michael Stevens dive into the weird science of calories. From century-old experiments involving fire, body heat, and human digestion to the hidden quirks of modern food labelling. Do “negative calorie” foods really exist? Where does burned fat actually go? Why chewing matters more than you’d think, and how your body is constantly leaking energy out into the universe. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    How To Use a Black Hole To See Your Past
    2026/05/04
    What if the universe is recording everything you’ve ever seen and done? In this episode, Hannah Fry and Michael Stevens explore the idea that light itself might carry a record of the past. And if it did, how could we watch history unfold by capturing it. Could a perfectly placed mirror or even a black hole bend that ancient light back to us? Could we watch the pyramids being built, or hear Einstein’s final words? From a nano-second old reflection in a mirror to the photons drifting through billions of miles of space, they reveal how everything we see is already gone, and uncover surprising truths about time, perception, and our own DNA. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    What can a humble airplane sick bag teach us about physics, engineering, and the limits of the human stomach; And why are there people out there collecting thousands of them? Professor Hannah Fry and VSauce’s Michael Stevens turn an unlikely holiday prompt into a surprisingly rich exploration of flight. From the biology of motion sickness to the physics of turbulence, and from exploding crisp packets to next-generation aircraft design, they unpack how flying messes with your body and how science has made it (mostly) better. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    How does a perfectly symmetrical ball of cells become an animal, with a head, a tail, and complex zebra or leopard like patterns? In this episode, we dive into the mind bending science of how order emerges from chaos, guided by an unexpected genius: Alan Turing. From leopard spots and human embryos to crime hotbeds, Hannah and Michael discover the hidden mathematical rules shaping life itself…and the ethical dilemmas that come with them. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).
