    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.

  • Skull rewrites story of human evolution; Autism and Tylenol; discovery of wind coming from black hole

    Skull rewrites story of human evolution; Autism and Tylenol; discovery of wind coming from black hole
    Sep 26 2025
    Episode 322 An ancient skull discovered in China may have just rewritten the story of human evolution. It’s widely accepted that the common ancestor of Homo sapiens, Denisovans and Neanderthals came out of Africa. But this skull upends that assumption - potentially showing human evolution began in Asia. Discover how a new reconstruction of the Yunxian fossil skull could push back human origins by 400,000 years. Tylenol does not cause autism. The US government has made headlines with claims that this common painkiller, also known as paracetamol, is playing a big role in what’s been falsely dubbed the ‘autism epidemic’. As Donald Trump and Robert F Kennedy Jr call for pregnant women to avoid Tylenol, we discuss what we know from science, and hear from medical experts of the danger of this new advice. Sagittarius A*, the supermassive black hole at the centre of our galaxy, is more active than we thought. Historically our black hole has seemed rather quiet. But a new discovery shows the first clear evidence of winds - streams of hot gas - coming from it. The finding could help us figure out what Sag A* looks like and what it’ll do in the future. Chapters: (00:00) Intro (01:05) This skull could rewrite the story of human evolution (16:39) Autism and Tylenol (26:26) Black hole discovery Hosted by Rowan Hooper and Penny Sarchet, with guests Michael Marshall, Grace Wade, Alex Wilkins, Chris Stringer, Arthur Caplan and Gretchen Goldman.

  • The evolutionary price we pay for longer lives; the asteroid coming VERY close to Earth; how dinosaurs shaped the ecosystem

    The evolutionary price we pay for longer lives; the asteroid coming VERY close to Earth; how dinosaurs shaped the ecosystem
    Sep 19 2025
    Episode 321 Humans live a lot longer than other primates - and much of that is down to our immune system. But there’s a price we pay for the capacity to fight off infections: inflammation. Chronic inflammation is to blame for a range of health issues, especially those related to older age. And now research has revealed exactly why inflammation is good for longevity but bad for health. Find out how proteins called death-fold domains often malfunction - and what this could mean for the future of drug development. Bigger than the Eiffel Tower and closer than the moon - the asteroid Apophis will skim past Earth in 2029 and will be visible to the naked eye. Don’t worry, astronomers assure us it will NOT hit us. But it could be a good testbed for NASA’s asteroid deflection technology, helping us to prepare for more dangerous space rocks in the future. With two major space agencies due to visit Apophis - what will we find? If you thought there was nothing new to learn about the extinction of the dinosaurs, think again. Something we hadn’t yet considered was the impact dinosaurs had on the ecosystem. Given they were so massive, dinosaurs made wide-ranging changes to the planet’s landscapes, such as shifting rivers. So when they were wiped out, there were huge knock-on effects, which researchers have now been examining.

  • Why we can't announce life on Mars (yet); The Romans' impact on the British economy; Link between exercise and your microbiome

    Why we can't announce life on Mars (yet); The Romans' impact on the British economy; Link between exercise and your microbiome
    Sep 12 2025
    Episode 320 Was Mars once home to alien life? The evidence is stronger than ever, since NASA’s discovery of rocks marked by patterns similar to those made by microbes on Earth. Found in an area now named Bright Angel, these rocks give us a tantalising insight into Mars’ ancient past - but just how definitive is this finding? It’s long been thought that when the Roman Empire withdrew from Britain in the early 400s, the result was chaos and economic collapse. But a new archaeological discovery suggests that’s not the case. Signs show a boom in the ancient metalworking trade around that time. Do we need to rethink this period of our history entirely? We’re constantly discovering more and more ways to boost our microbiome and improve our health – everything from eating more fibre and fermented foods to having pets and embracing dirt. And now there’s something else to add to the list: weight lifting. After being put on a weight training programme, a group of sedentary adults showed a surprising uptick in beneficial gut bugs. But how are the two things connected? Chapters: (00:00) Intro (01:19) Strongest evidence for past life on Mars (14:55) The Romans impact on the British economy (23:19) Link between exercise and your microbiome Hosted by Rowan Hooper and Penny Sarchet, with guests Mike Marshall, Mike Tice and Sanjeev Gupta.

  • First complete map of brain activity; Queen ant lays eggs of another species; The perils of scrolling while on the toilet

    First complete map of brain activity; Queen ant lays eggs of another species; The perils of scrolling while on the toilet
    Sep 5 2025
    Episode 319 Scientists have created the first complete activity map of a mouse’s brain. Combining brain images from multiple mice, researchers recorded more than 650,000 neurons while these mice manipulated little Lego steering wheels in a driving game. This complex behaviour has allowed scientists to examine the interplay between various parts of the brain - and could help us better understand consciousness. This might be the weirdest discovery about ants ever. Some eggs laid by Queen Iberian harvester ants (Messor ibericus) contain males of another species - that of the builder harvest ant (Messor structor). They are somehow cloning these males to create workers for the colony - a highly unusual form of reproduction. Find out how they’re doing it - and let us know what your favourite ant is. Do you scroll on your phone when you’re on the toilet? Well, you might want to stop doing that. For a long time we’ve thought straining on the loo increased your risk of developing haemorrhoids, also known as piles. But a new study shows it might be more to do with how long you’re spending on the loo. Find out how scrolling through addictive apps could increase your risk of haemorrhoids by 50 per cent.

    Scientists discovered a 100,000-year-old organism; Breakthrough brain implant uses AI to treat pain; How climate change leads to revolutions
    Aug 29 2025
    Episode 318 An ancient organism has been discovered that has been alive for at least 100,000 years. Found in the Siberian permafrost, this lifeform doesn’t appear to have just remained dormant - but instead has actually been growing extremely slowly. Our understanding of life is already quite fuzzy, and this finding adds to the idea that life itself is a fuzzy state of being. A breakthrough method of treating previously untreatable chronic pain is showing promise. An intuitive form of deep brain stimulation, guided by machine learning, has provided targeted relief to patients in a small trial. The method also improved various other conditions and may even help with weight loss. Find out how it works. Throughout history, dramatic changes in the climate often coincide with major revolutions and rebellions. Rapid warming or cooling often have a cascading effect on food production, leading to shortages and rising prices. As the effect of climate change increase today, will we see a repeat of history? Chapters: (00:00) Intro (00:22) 100,000-year-old organism (10:37) Brain implant treats chronic pain (18:02) How climate change leads to revolutions Hosted by Rowan Hooper and Penny Sarchet, with guests Alexandra Thompson, James Dinneen and Karen Lloyd.
