Brian Cox and Robin Ince dig into de-extinction asking, could we and should we resurrect creatures of the past? They are joined by geneticist Adam Rutherford, palaeontologist Susannah Maidment and comedian/virologist Ria Lina.

Extinction has played a significant role in shaping the life we see on Earth today. It is estimated around 95% of species to have ever existed are already extinct - but could any of these extinctions be reversed? Our panel explore the different methods being pursued in these resurrection quests, including back-breeding, cloning and genetic engineering. They take a close look at the case of the woolly mammoth and the suggestion they could be returned to the Arctic tundra. Some claim the mammoth is the key to ecosystem restoration, but our panel have some punchy opinions on whether this Jurassic Park fantasy is even ethical.

Brian Cox and Robin Ince expand their knowledge of elasticity with Olympian Bryony Page, comedian Jessica Fostekew & experts Dr Anna Ploszajski and Prof James Busfield from Queen Mary University of London.

What makes stretchy things stretch? Together our panel journey through different applications of elastic materials and examine, at the molecular level, what happens when we stretch a material and crucially what causes it to return to its original shape. This is especially pertinent to our guest Olympic and British champion trampolinist Bryony Page who has capitalised on elasticity in her 24 year long career. We discover that the bounce of a trampoline mainly comes from the elasticity of steel and how dependent this is on temperature. Cold temperatures are not only treacherous for trampolines; we explore how the cold proved fatal to the elastic components of both the Titanic and the Challenger space shuttle.

Plus we hear how scientists sometimes just can’t beat nature; natural rubber and spiders silk are two such cases. Anna Ploszajski takes us through some of the more inventive techniques scientists have engineered to produced more of these natural materials, including genetically engineering goats to be milked for silk.

Brian Cox and Robin Ince investigate the science of baby making - don’t worry, all theory, no practice! They are joined by Professor Joyce Harper, Dr Ben Steventon and comedian Sara Pascoe to discuss how just two cells can turn into trillions, or in other words, how an embryo can turn into an embryologist.

The embryo-building processes across species are remarkably similar, yet there is still so much we don’t know about the beginning of life. Our panel discuss these unknowns, the latest in fertility treatments and what new capabilities might be available to future parents. It seems that artificial wombs may not be science fiction for much longer and scientists are closing in on being able to make egg and sperm cells out of stem cells. So yes, Brian and Robin could one day have a baby!

Brian Cox and Robin Ince consider how different our understanding of the universe would be without the stars. They are joined by Maggie Aderin-Pocock, Roberto Trotta and comedian John Bishop who illuminate all that we have learnt from the stars and how different life would be without them.

Every culture has looked up at the night sky, but why are we so drawn to the pin pricks of light in the sky above us all and how have they helped shape human civilisation? Roberto Trotta takes us back to the origins of astronomy, to women who he believes were the first astronomers, linking the orbital period of the moon with the length of the menstrual cycle. We continue the historical journey, through the astronomical greats, Galileo, Copernicus and Kepler, who all in part owe their scientific discoveries to the stars. Our panel marvel at how we, an infinitesimally small part of the universe, are able to look up at the stars and comprehend what is beyond and how this stargazing has profoundly shaped our sense of selves as well as underpinned science as we know it.

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!

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.

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.

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.

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.
