'Beastly Bodies' Kids Special - Steve Backshall, Jess French and Adam Kay

Brian Cox and Robin Ince emerge from the hedge row waking up their guests from hibernation to discuss the fascinating lives of Britain’s favourite mammal, the hedgehog. They are joined by hedgehog experts Hugh Warwick and Sophie Lund Rasmussen (also know as Dr Hedgehog), and by broadcaster and poet Pam Ayres. Sophie Lund Rasmussen has crowd sourced 14 freezers worth of dead hedgehogs for her research and has brought one of her more unique samples with her, the penis of the oldest known hedgehog who reached a stupendous 16 years of age! Together our panel snuffle their way through the evolution of hedgehogs, their life cycle and how to stop them getting run over by robotic lawn mowers!Producer: Melanie Brown Executive Producer: Alexandra Feachem Researcher: Olivia JaniBBC Studios Audio production

Brian Cox and Robin Ince head to Bletchley Park with comedian Alan Davies, and cyber experts Victoria Baines and Richard Benham to decode cyberwarfare and discuss its future.As computers have shrunk from the size of rooms to fitting in our jacket pockets, our cyber sleuths explore the changing nature of cyber-attacks and defence. They decipher the fancy jargon abounding in cyber land, from trojan horses to phishing scams and reveal how prolific these attacks are on nation states, businesses and the public. From digital army battalions to teenage freelance hackers, the cyber-villains are multiple and varied. Our panel discusses the aims of these malevolent forces; from extorting money and holding valuable commercial data hostage to influencing people’s electoral intent.The panel explores how AI and quantum computing are supercharging cyberwarfare – but in good news, also cyber-defence. Alan Davies shares his susceptibility to being tricked online whilst our experts give some tips for staying safe online, and finally, Alan comes up with his surprising alter-ego hacking name.Producer: Melanie Brown Executive Producer: Alexandra Feachem Researcher: Olivia JaniBBC Studios Audio production

Are we alone in the universe? Brian Cox and Robin Ince venture to Glastonbury in the search for alien life and are joined in their galactic quest by comedian Russell Kane and astronomers Lisa Kaltenegger and Chris Lintott. They imagine the sorts of worlds that might best host alien life, how some of the biological and technological signatures of alien life might appear as well as how evolution might shape this life. They discuss some of the mysterious signatures that have appeared as well as how hard it is to really know what you're looking for and how objects like faulty microwaves have muddied the alien-finding waters.Producer: Melanie Brown Exec Producer: Alexandra Feachem BBC Studios Audio production

Brian Cox and Robin Ince raid the archives of the Royal Society to reveal an unexpected history of science with guests Rufus Hound, Tori Herridge, Matthew Cobb and Keith Moore. Together they explore some of the surprising and wackiest scientific endeavours undertaken by early members of the Royal Society from the discovery of sperm to testing the insect repelling properties of unicorn horn. They hear how a beautiful book on fish almost scuppered Newton's Principia Mathematica and why a guide to the fauna of Switzerland ended up including depictions of dragons.Producer: Melanie Brown Exec Producer: Alexandra Feachem BBC Studios Audio production

Brian Cox and Robin Ince talk hot air as they explore the pivotal role of gasses in our lives. Joining them to add some CO2 to the mix is material scientist Mark Miodownik, chemist Lucy Carpenter and comedian Dave Gorman. They discuss how humans came to even understand it existed in the first place as well as how many of the innovations in modern society have been underpinned by this mostly invisible and odourless substance. We laud the humble (or is it noble?) gas and its key role in technological innovation - from using laughing gas in anaesthesia to the combustion engine and of course the most important of all, the power source behind squirty cream.

Brian Cox and Robin Ince venture to the home place of exploration in Porto, Portugal at the Explorers Club as they discuss science at the extremes of exploration. Joining them is volcanologist Jess Phoenix, astronaut Mike Massimino, astrobiologist and oceanographer Britney Schmidt as well as adventurer and broadcaster Anneka Rice. They discuss breaking robots under the Antarctic ice shelf, chasing after narco-traffickers to retrieve a rock hammer and how viewing the earth from the vantage point of space can profoundly influence how you feel about humanity.

Brian Cox and Robin Ince are joined by adventurer and naturalist Steve Backshall, veterinarian Jess French, and comedian and former doctor Adam Kay, as they are put to the test by an audience of curious children at Cheltenham Science Festival. We find out who would win in a battle between a shark and a crocodile (the answer involves a tennis court), why dogs don’t sweat like humans, whether macrophages might help us overcome antibiotic resistance and if AI might one day enable us to understand and directly communicate with animals.Producer: Melanie Brown Exec Producer: Alexandra Feachem BBC Studios Audio Production

Brian Cox and Robin Ince go past jail, climb a ladder and build a civilisation as they explore the science behind our favourite board games. Joining them in the library (or was it the conservatory?) is mathematician Marcus du Sautoy, who discusses the global history of games as well as his tips for winning at Monopoly. Joining him is games designer and play researcher Dave Neale who explains how key games are to developing a theory of mind, alongside Jessica Fostekew, comedian and gaming enthusiast who admits to becoming a more ruthless gamer as time goes by.Producer: Melanie Brown Exec Producer: Alexandra Feachem BBC Studios Audio Production

Brian Cox and Robin Ince leaf through the latest tree science with Dame Judi Dench, Tony Kirkham and Tristan Gooley. Dame Judi Dench shares her great love for treekind and describes how over time she has come to create a small woodland in her garden and how meaningful that is for her. Tony Kirkham, former head of Kew Arboretum and Gardens, shares some of the amazing journeys he's been on to find unusual and rare trees around the world. Navigator Tristan Gooley has spent a lifetime learning how to read trees, he explains how nearly everything on a tree can provide clues into the environment around it and how elements like leaf shape and colour can help us to use trees as a compass to navigate our way.Producer: Melanie Brown Exec Producer: Alexandra Feachem BBC Studios Audio production

`This week it's over to you the listeners, as we hear some of your favourite moments from The Infinite Monkey Cage. Comedian Claire Hooper hears about the mating rituals of spiders, which use several of their legs in this complex process. But she discovers the females of the species get their own back by eating the males once the deed is done. Comedian Noel Fielding explains how he made a plasticine figure of singer Joey Ramone, prompting Robin to wonder about the pitfalls of building a real-life Frankenstein. And writer Alan Moore tells Jonathan Ross how he used string theory as inspiration for a comic strip... about a virtuoso violinist.New episodes are released weekly on Wednesdays.
