  • Space 2075: How Humanity Will Live, Work and Make Drugs off-planet | Live Recording at the Royal Society

    Space 2075: How Humanity Will Live, Work and Make Drugs off-planet | Live Recording at the Royal Society
    Oct 13 2025
    A special episode all about the future of space exploration, recorded in front of a live audience at the Royal Society in London. Earlier this year, the Royal Society published ‘The Space: 2075 report’, which recognises the huge changes we’re seeing in space exploration, and urges for action to be taken to make sure the next 50 years of activity in space is sustainable and benefits all of humanity. We brought together a panel of space experts to discuss the accelerated advances we’re seeing. Helen Sharman, the first British astronaut, blasted off Earth on a Soyuz rocket in 1991. She explains what it’s like to journey into space, the various ways it impacts the body and why humans still have the edge over robots for certain missions. Irene Di Giulio is a Biomedical Engineer at King's College London. She explores her work helping to get the first disabled astronaut to space and why it’s critical we push towards making space flight accessible. And Katie King is Co-Founder and CEO of BioOrbit, a pharmaceutical company which plans to make drugs in space. Discover why space is the perfect place to create drugs - potentially bringing at-home cancer treatments to the market. Hosted by Rowan Hooper and Abby Beall.

  • How Jane Goodall changed the world; How the universe ends; How “selfish sperm” affect male fertility

    How Jane Goodall changed the world; How the universe ends; How “selfish sperm” affect male fertility
    Oct 10 2025
    Episode 324 The legendary primatologist Jane Goodall died last week aged 91, leaving behind a remarkable legacy. Her work studying tool use in chimpanzees completely reshaped the way we view animal intelligence. Fiercely protective of the natural world, she was also responsible for a huge amount of advocacy during her life. Primatologist Alejandra Pascual-Garrido worked directly with Jane and shares the story of her life and work. Will the universe end with a bang, or a quiet whimper? Katie Mack is a cosmologist, science communicator and best-selling author of The End of Everything. She explores why she’s fascinated by how the universe might end, the most likely scenarios for how it happens and why it’s an exciting time for both physics and cosmology. She also offers her thoughts on the recently announced Nobel Prize in Physics - and teases her upcoming book How To Build A Universe. Older fathers may have a bigger impact on the health of their offspring than we realised. We know that sperm accumulates mutations as men age, but a study sheds new light on the risks. Men aged 70 are twice as likely to have children with serious genetic disorders. And it’s all to do with “selfish sperm”. Chapters: (00:51) Jane Goodall’s legacy (20:52) Kate Mack on the end of the universe (38:47) Selfish sperm Hosted by Rowan Hooper and Penny Sarchet, with guests Alejandra Pascual-Garrido, Katie Mack and Michael Le Page.

  • Emergency in Antarctica; How movement changes the brain; Why women live longer than men

    Emergency in Antarctica; How movement changes the brain; Why women live longer than men
    Oct 2 2025
    Episode 323 Temperatures in Antarctica have soared by over 35°C. Scientists are concerned about how quickly things are changing on the continent as these warmer temperatures impact the polar vortex. Coupled with record lows in sea ice cover over the last decade, this could be a sign that Antarctic weather patterns have shifted permanently. What’s driving this change - and what happens if we have reached a tipping point of no return? Many mammals, including cats, can pivot their ears to focus on a particular sound. But our ears aren’t quite so flexible. But now it appears that a similar process happens inside our brain - ‘swivelling’ to focus on sounds from different directions. This has only recently been discovered thanks to new portable EEG equipment, as the process only happens when we’re moving. This finding may help us better understand how movement changes the brain - and could even help improve hearing aids. Why do women tend to live longer than men? It could have something to do with the very chromosomes that determine biological sex. By looking at birds, whose sex chromosomes differ from those of mammals, researchers have discovered an intriguing hint at what’s going on. But does their new hypothesis hold up? Alongside all the emerging science, Rowan shares his own theory. And the team discusses the disappearance of the Y chromosome - and what that really means for men.
