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”.

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.

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.

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.

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.

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.
