  • This breakthrough could let gay couples have biological kids

    This breakthrough could let gay couples have biological kids
    2025/06/27
    A groundbreaking experiment in reproductive biology has resulted in mice being born from two biological fathers. By fusing sperm and putting them into an emptied egg cell, researchers in China have produced healthy and fertile offspring from two male mice. While it’s early days and the technique requires hundreds of embryos to get results, it opens up the possibility of same-sex reproduction in mammals, including humans, in the future. New insights into the power of sleep reveal how short naps can boost creativity. A study found that reaching a certain stage of sleep, known as N2, significantly increased people’s chances of having an “aha!” moment. It’s more evidence of how deeply intertwined sleep is with problem-solving and innovation, and why naps might be more productive than we thought. One ancient lizard family managed to survive the asteroid that killed the dinosaurs, and they’re still around today! Scientists have traced the lineage of night lizards back to over 90 million years ago. Their ability to shelter underground and survive on little energy may have helped them live through one of Earth’s biggest disasters. Chapters: (00:38) Same-sex reproduction breakthrough (12:09) Power naps and creativity (22:37) Ancient lizard survives dinosaur-killing asteroid Hosted by Rowan Hooper, Penny Sarchet, and Michael Le Page.

  • First skull of mysterious human ancestor; Decoding whale language; Heatwaves 20x more likely to happen

    First skull of mysterious human ancestor; Decoding whale language; Heatwaves 20x more likely to happen
    2025/06/20
    Episode 308 An ancient skull discovered in China has been confirmed to belong to a Denisovan. It’s been tough to study this mysterious human ancestor, as we’ve only ever found a finger and jaw bone - so this new discovery could reshape our understanding of them. After being kept secret for decades, the “dragon man” skull is opening up a new window into our past. We’ve unlocked another clue in our quest to decode whale language. Analysis of 15 sperm whales in the Caribbean suggest their language may contain vowels, used in a similar way to human language. Using their various clicks, researchers have discovered interesting patterns in the way they communicate. Feeling hot and sweaty? Well, strap in - because these heatwaves are set to continue…and get worse. Summers are evolving fast as a result of climate change and weather events that would’ve once been rare are becoming much more common. Find out how the UK could be in for a string of long 40C summers in the very near future. The winner of The Women’s Prize for Non-Fiction has been revealed - Dr Rachel Clarke claims the title for her book “The Story of a Heart”. The book explores the history of heart transplants and tells the story of a nine year old girl whose heart saved two other children and two adults. Rachel explains why she chose to write this story and the surprising things she learnt along the way. Chapters: (00:41) Denisovan skull discovery (14:02) Deconding whale language (18:14) Hot summers becoming more common (26:16) Winner of The Women’s Prize for Non-Fiction Hosted by Rowan Hooper and Penny Sarchet, with guests Madeleine Cuff, Mike Marshall, Gillian Kay, Alison Flood and Rachel Clarke.

  • Is this the first step to cyborg brains? How drones are reshaping warfare forever; New Vera Rubin observatory goes live

    Is this the first step to cyborg brains? How drones are reshaping warfare forever; New Vera Rubin observatory goes live
    2025/06/13
    Episode 307 Using new “ultrasoft” electronics, researchers at Harvard have effectively created tadpole cyborgs. A soft bioelectronic device has been implanted into their brains - one which grows with them as they develop into frogs. This neural implant is a first step in helping us better understand the inner workings of the brain. But could this work in mammals…or humans? Discussing just that, the Royal Society held a meeting this week called Cyborg Futures. How soon until humans become one with machines? A small fleet of cheap drones has been deployed by Ukraine’s security service, causing $7 billion of damage to Russian air power. Just 117 drones were able to take out a third of Russia’s nuclear bomb force. Difficult to catch, hard to jam and nearly impossible to shoot down - are drones a paradigm shift in warfare? The Vera Rubin Observatory in Chile has just opened, promising to carry out a legacy survey of space and time. US editor Chelsea Whyte visited the newly operational telescope to see how it will map out the night sky in never-before-seen detail. Learn how it hopes to answer some of the biggest mysteries about dark matter and dark energy - and find out about the legacy of Vera Rubin, the astronomer the telescope is named after. Think net-zero climate action is costing us way too much, driving up living costs and damaging the economy? Think again. The Organisation for Economic Co-operation and Development (OECD) has taken on all of the misinformation circulating about our goal to achieve net zero emissions, showing that raising climate ambition would actually boost the global economy. Find out why. Chapters: (00:32) Frogs with cyborg brains…are humans next? (11:25) How drones are reshaping warfare (16:16) Vera Rubin observatory opens (24:59) How net zero will boost the global economy Hosted by Rowan Hooper and Penny Sarchet, with guests Alexandra Thompson, Chelsea Whyte, Jonathan Rossiter, Tamar Makin, Robert Bunker and Simon Evans.
