  • Nikola Tesla Fell In Love with a Pigeon

    Nikola Tesla Fell In Love with a Pigeon
    Jun 3 2026
    What do lightning, wireless electricity, Cambridge dining etiquette, hypnosis, and a lovestruck pigeon have in common? The answer is (of course) Nikola Tesla. In this episode of The Rest Is Science: Field Notes, Michael and Hannah experience a real Tesla coil, exploring the spectacular physics behind one of Tesla's most famous inventions. Why do these devices create miniature lightning storms? How did Tesla dream of delivering wireless electricity to the entire planet? But there was a stranger side to Tesla's life too, from his fear of pearls to the heartfelt story of the white pigeon he claimed to love "as a man loves a woman." Plus, your questions: the science of hypnosis, the oldest symbols still in use today, why Cambridge professors have personal napkin rings, and whether ‘nothing’ can ever truly exist. ------------------- 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).

  • Michael Discovered A New Way To Make Twins

    Michael Discovered A New Way To Make Twins
    May 31 2026
    Is there a new way to make twins? If there is, Michael's might just have discovered it. And hint: it's going to hard work. From Hannah’s twin-like sister to the most famous cells in human history, in this episode Hannah and Michael continue to explore whether we truly own of ourselves, this time at a microscopic level. From our genome, to our cells and even our personalities, what happens in a future where cloning is the norm? Where Zygotes might be used to create mini-Michaels? And where reproduction as we know it now is...optional. ------------------- 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).

  • Why Michael Abandoned Ink

    Why Michael Abandoned Ink
    May 27 2026
    What can be revealed about a person by their choice of…lead? In this gloriously nerdy episode of Field Notes, Michael Stevens arrives armed with an entire collection of mechanical pencils, sparking a series of passionate debates about graphite, the merits of ink, and whether the perfect pencil will ever really exist. Plus: what happens to fizzy drink bubbles in zero gravity? Why did early scientists believe sperm contained tiny pre-formed humans? Are gravitational waves the most beautiful thing in the cosmos? And are modern scientific discoveries becoming too complicated for any one person to fully understand? ------------------- 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).

  • Do You Own Your Own Foot?

    Do You Own Your Own Foot?
    May 24 2026
    What happens to a body part once it’s been removed from your body? Can you take it home? Cremate it? Bury it? Even give it a funeral? In the first episode of a new mini-series on ownership, Hannah and Michael explore a deceptively simple question: what parts of ourselves do we actually own? From amputated limbs and stolen skulls to black markets for human organs, they uncover the strange, unsettling, and often lucrative world of body ownership. Why did grave robbing help advance modern medicine? When are flesh-eating beetles surprisingly useful? Who owns your organs after you die? And what does the bizarre fate of Einstein’s brain reveal about the blurry line between science, consent, and control after death? This episode asks: do our bodies really belong to us? ------------------- 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).

  • Hannah Predicted a Pandemic

    Hannah Predicted a Pandemic
    May 20 2026
    What if the next pandemic could be predicted before it even begins? Hannah and Michael step into the unsettling world of outbreak simulations, where scientists map invisible infections, model human behaviour, and try to stop global catastrophe before it starts. Some warnings save millions. Others get ignored, until it’s too late. After the break the conversation takes a turn into space stations, fizzy drinks in zero gravity, the first microscopes, and gravitational waves bending the fabric of spacetime itself.

  • DARK vs LIGHT

    DARK vs LIGHT
    May 17 2026
    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
    May 13 2026
    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"

    "A Grim Enemy For Reasons We Do Not Yet Comprehend"
    May 11 2026
    * 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).
