Brian Cox and Robin Ince are joined by comedian and author David Baddiel, psychologist Prof Karen Douglas, biologist Prof Matthew Cobb and philosopher Dr Timotheus Vermeulen to discover why conspiracy theories and conspiracy theorists seem to be booming. From flat earthers to moon hoaxers and holocaust deniers, is there something about society today that encourages beliefs that seem to go against all evidence and reason? Or are conspiracies just part of the human condition, and each to their own? Why do some of these alarming theories seem to hold more truth for many than overwhelming data and evidence to the contrary, and how far should we go in accommodating views that seem to have no basis in reality?

Brian Cox and Robin Ince tackle the thorny issue of their own differing experiences of ageing, as they find out why Robin seems to be doing it so much more quickly than Brian and whether science might have the answer. They are joined by comedian Sarah Kendall, Professor Dame Linda Partridge, world-renowned expert on the biology of ageing, and Dr Andrew Steele, author of "Ageless: The new science of getting older without getting old." Can the scientists answer the age-old monkey cage question of why Robin looks so much older than Brian despite being several years younger? Is it all the donuts he ate in his twenties or is down to his genes? Why do any of us age at all, and is there a biological limit to human lifespan. Most tantalisingly, they discover how the latest science into the biology of ageing could produce medicine that could slow down some of the ageing processes in the body, and in the process prevent many of the diseases, such as cancer and dementia, that can make old age so challenging. With these new advances comes the exciting prospect of not only living longer, but more importantly living healthier and happier and free of disease well into our hundreds.

Brian Cox and Robin Ince continue their LA science adventure as they visit Caltech in Pasadena to meet the scientists hunting for planets orbiting distant stars in solar systems far far from our own. They are joined in their quest by Python Legend Eric Idle and Exo-planet hunters Dr Jessie Christiansen from Caltech and Dr Tiffany Kataria from NASA's JPL who are using the latest telescopes to identify distant planets outside of our own solar system. Despite their distance from us, incredible new techniques allow exoplanet hunters to paint extraordinary pictures of the atmospheres and conditions on some of the 500 or so planets that have now been identified, and allow for the tantalising possibility of one day identifying other earth like planets that could even support life. Brian and Robin chat to Sean about what the discovery of life elsewhere out in the cosmos might mean for life here on planet earth, or whether the fact we haven't found any yet is evidence we are in fact all alone?

The Infinite Monkey Cage teleports to California for this special episode recorded at NASA's Jet Propulsion Laboratory. They are joined by comedian and talk-show host Conan O'Brien, alongside JPL's Dr Katie Stack Morgan and Dr Kevin Hand, and discuss the incredible missions that are hunting for signs of life within our own solar system. From the iconic Mars Rovers currently exploring the martian surface, to amazing future missions to Jupiter's icy moon Europa, the panel discuss the tantalising prospect of finding signs of life this close to home, and the incredible engineering and ingenuity that goes into planning these missions.

Brian Cox and Robin Ince return for a new series with an illustrious panel of experts to discuss what scientists have learnt from Covid and what we have all learnt about the nature of science by watching it happen so spectacularly over the course of the pandemic. They are joined by Dame Sarah Gilbert, creator of one of the very first Covid vaccines, Immunologist Prof Dan Davis and Dr Chris Van Tulleken, infectious disease clinician and broadcaster. They discuss the incredible speed of vaccine delivery and whether we have learnt lessons for future pandemics, the gaps that Covid has revealed in our knowledge of our immune system, and what the public have witnessed in terms of science happening in real time as we all lived through the pandemic.

Brian Cox and Robin Ince are joined by comedian Sara Pascoe and the very numerate Prof Hannah Fry, maths comedian Matt Parker and statistician Prof David Spiegelhalter for a unique maths class. Are some of us just innately bad at maths or can everyone get to grips with algebra and calculus? What do our panel wish they'd been taught at school, and what is the key to a life-long love of numbers? Get your calculators ready!

Brian Cox and Robin Ince are joined by comedian Alan Davies and neuroscientists Prof Uta Frith and Prof Sophie Scott. They discover the secret to why humans are such social creatures and why two brains are definitely better than one. Our brains are wired to learn from and mimic other brains we come into contact with, even though most of the time we don't even realise that is what they/we are doing. The subtle cues we get from other people and the information in their brains, affects our own wiring and experience of the world. With this incredible complexity, might we ever be able to create an artificial brain that mimics our own and the human experience?

Brian Cox and Robin Ince look back at Planet Earth from the unique perspective of space with the help of astronauts Nicole Stott and Chris Hadfield, Space scientist Carolyn Porco and comedian and author Katy Brand. What can we learn about our own planet by looking back at it from space? The panel talk about the emotional response of looking back on earth, either from the ISS or via amazing photographs like Voyager's Pale Blue Dot, and the importance of realising our own place and significance in the vast cosmos.

Brian Cox and Robin Ince are joined by Monty Python's Eric Idle, and cosmologists Dr Netta Engelhardt and Dr Janna Levin as they tackle one of the biggest challenges in cosmology. What happens when you throw something (Robin!) into a black hole? Is the information about Robin lost forever, or is there a chance, sometime in the far future, a super intelligent alien civilisation could piece back some key information to discover proof he ever existed? Are Robin and his cardigans lost for all eternity?

Brian Cox and Robin Ince are joined by Ted Lasso's Brendan Hunt, Professor of forest ecology and author of "The Mother Tree", Suzanne Simard and botanist Mark Spencer to discover how trees and plants communicate and what they are saying. Suzanne's incredible discovery that trees form a wood wide web of communication has changed our entire understanding of forests and how they work. With the help of amazing fungi, this incredible network of communication allows the trees and plants in a forest to pass information backwards and forwards to help protect themselves against predators and optimize resource. Incredibly, this could even be viewed as a form of intelligence. Brian and Robin find out how this should change the way we look at all plants, and in particular how we manage our forests and discover some of the secrets of those whispering trees.
