  • 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
    Jun 20 2025
    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.

  • 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
    Jun 13 2025
    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.

  • $1 trillion of platinum on the moon; how your brain distinguishes between reality and imagination; rise of the hyperworm

    $1 trillion of platinum on the moon; how your brain distinguishes between reality and imagination; rise of the hyperworm
    Jun 6 2025
    Episode 306 It’s been discovered that the moon is probably home to $1 trillion worth of platinum. Researchers suggest nearly 6500 of the Moon’s craters were made by asteroids containing commercial quantities of platinum, palladium, rhodium, ruthenium, iridium and osmium. Does that mean space companies are going to head out on mining missions imminently…and should they? Hear the reasons for and against mining on the Moon. When you imagine something in your mind, how does your brain know that it’s not real? Certain brain regions have been identified in a new experiment which help keep reality and make-believe separate. This finding could tell us a lot about conditions like schizophrenia - or what’s going on when we dream. It may even answer that question; are we living in a simulation? Read our imagination special here: https://www.newscientist.com/issue/3545/ A newly discovered emergent behaviour has been found in nematode worms - the world’s commonest animal. These millimetre long worms are able to merge to form superorganisms, creating tentacles or towers that can straddle long distances. Learn about this collective behaviour and how it's coordinated.
