The Infinite Monkey Cage

BBC Radio 4

Professor Brian Cox and Robin Ince host a witty, irreverent look at the world through scientists’ eyes. Joined by a panel of scientists, experts and celebrity science enthusiasts they investigate life, the universe and everything in between on The Infinite Monkey Cage from the BBC. From the smallest building blocks of life to the furthest stars, the curious monkeys pull apart the latest science to reveal fascinating and often bizarre insights into the world around us and what lies beyond. Can trees talk to each other? Can science help you commit the perfect murder? What might aliens look like and the burning question of our time, are strawberries alive or dead? Join them as each episode they put a different scientific topic under the microscope, from aliens, black holes and hedgehogs, to bacteria, poison and the Big Bang. With past guests including actors Dame Judi Dench and Sir Patrick Stewart, comedians Steve Martin and Conan O’Brien, astronaut Tim Peake, primatologist Jane Goodall and mathematician Hannah Fry, The Infinite Monkey Cage promises to make you laugh, enrich your knowledge and leave you with a deeper appreciation for the universe that we call home. Whether you’re a seasoned scientist or someone who nodded off in physics class, listen in to learn all about funny, fascinating and sometimes ridiculous topics – with the occasional monkey business.

    Head in the Clouds - Owain Wyn Evans, Gavin Pretor-Pinney, Amanda Maycock

    Robin Ince and Brian Cox look up to the heavens as they try to ‘de-mistify’ the foggy science of clouds. They’re joined by Cloud Appreciation Society founder Gavin Pretor-Pinney, climate scientist Amanda Maycock, and former weather presenter and drummer Owain Wyn Evans, for a whirlwind tour of our too often-overlooked aerial realm.

    The panel explores how clouds form, why they take such extraordinary shapes, and how satellites and weather balloons help us keep track of them. They discover why low clouds cool the planet but high clouds warm it and why a cloud that weighs as much as a jumbo jet manages to stay up in the sky. From the physics of a crisp packet balancing on a cumulonimbus to the shimmering beauty of noctilucent clouds, tune in for this cirrus-ly fascinating episode.

    Fusion – Ria Lina, Yasmin Andrew and Howard Wilson

    Robin Ince and Brian Cox get all fired up, overcome their natural repulsion and come together for this stellar episode on nuclear fusion. They’re joined by plasma physicist Yasmin Andrew, fusion scientist Howard Wilson and comedian Ria Lina to uncover the secrets of star-making here on our planet.

    Together the panel discovers how the sun fuses atoms to release energy and why misbehaving, jiggling plasma makes this tricky to recreate on Earth. They explore the competing technological approaches — from giant magnets to the world’s biggest lasers — and find out that the hottest place in the solar system is, in fact, in Oxfordshire. Finally, they ask whether fusion could really provide an unlimited source of clean energy, or whether the technology will forever be “just 20 years away”.

    What’s the deal with eels? – Lucy Porter, David Righton and Caroline Durif

    Fishing rods at the ready, Brian Cox and Robin Ince attempt to reel in a creature that has baffled scientists since Aristotle: the eel. Wriggling in to help them uncover the mysteries of one of nature’s slimiest subjects are marine scientists David Righton and Caroline Durif, and comedian Lucy Porter.

    How do eels navigate such vast distances so deep under water? Why has no one ever seen them reproduce? And WHY would anyone eat them jellied with pie and mash?! The panel discovers that Spanish eels are always late and that eels from all different countries are thought to meet up somewhere in the Atlantic Ocean for a huge annual orgy.

    What’s the time? - Marcus Brigstocke, Leon Lobo, Louise Devoy

    Robin Ince and Brian Cox wind up at the Royal Observatory in Greenwich – arguably the centre of time – to uncoil the mysteries of what time is and how on Earth (…and on moon) we keep track of it. Taking the time to join them are comedian Marcus Brigstocke, curator of the Royal Observatory Louise Devoy, and Head of the National Timing Centre Leon Lobo.

    From ancient Egyptian knuckle counting to sun dials, quartz oscillators and atomic clocks, the panel turns back time to discover how we measured and kept it throughout history. Together, they dial into why Greenwich has become such an important place for time and how time is synchronised and sold across the globe. They explore the flaws and future of accurate astronomical and atomic timekeeping, and Marcus blames the ‘leap second’ for his fry-up failures.

    Mind-reading Computers – Phil Wang, Anne Vanhoestenberghe and Luke Bashford

    For once, Brian Cox and Robin Ince are on the same wavelength – with thinking caps firmly on, they plug into the science of brain-computer interfaces. Helping them decode the tech are neuroscientist Luke Bashford, biomedical engineer Anne Vanhoestenberghe, and comedian Phil Wang.

    Together the panel switches on to the possibilities of using implanted and wearable devices to restore movement, speech, sight… or even to decode thoughts themselves. From the ethics of cognitive enhancement to the future of mind-reading and immersive gaming, strap in for this electrifyingly thought-provoking episode.

    Illuminating Light - Jess Wade, Russell Foster and Bridget Christie

    What is light? How has it shaped our understanding of the universe, our biology, and even our culture? In this illuminating episode Brian Cox and Robin Ince shine a spotlight on the fascinating science and history of light. From sun and circadian rhythms to the dazzling complexity of quantum, they explore how humans have understood and been influenced by light across time. Joining them to shed light on the subject are physicist Dr Jess Wade, Neuroscientist Professor Russell Foster and comedian Bridget Christie. Together, they trace the story of light from early scientific theories to the cutting-edge research of today. Expect tales of light emitting eyes, the mystery of wave-particle duality and why Bridget thinks that if we had understood light better, we’d never have believed in ghosts!

    Technofossils - Sarah Gabbott, Mark Miodownik and Aurie Styla

    Brian Cox and Robin Ince dig deep into the strata of an imagined human history to unearth the curious concept of technofossils. Joined by paleobiologist Sarah Gabbott, material scientist Mark Miodownik and comedian and tech enthusiast Aurie Styla the panel unearth how the everyday objects that we throw away today compare to fossils of the past. Together, the panel investigates how these modern artifacts could degrade over time to become the fossils of the future. From old smartphones buried in bedside drawers to sprawling landfill sites, they imagine how these remnants of the Anthropocene might puzzle future archaeologists—and speculate on what these researchers might infer about our technology, customs, and way of life.

    Should We Settle in Space? - Tim Peake, Kelly Weinersmith and Alan Davies

    Brian Cox and Robin Ince blast off into a cosmic controversy as they ask, should humanity become an interplanetary species? At Harwell Campus, a space science innovation hub, they’re joined by astronaut Tim Peake, biologist and Royal Society prize winning author Kelly Weinersmith, and comedian Alan Davies to explore the science, ethics, and challenges of settling on Mars or on the Moon. Are we bold pioneers venturing into the unknown, or just reckless tenants abandoning Earth in search of a new abode? Our panel discuss whether space settlement is inevitable in humanity’s near future and how pushing the boundaries of space exploration could make extra-terrestrial travel more accessible to the masses. From sourcing materials, to surviving radiation, and even growing potatoes from poo, they tackle what it really would take to live a life beyond Earth!
