  • Two 'Extinct' Mammals Species Have Been Discovered in New Guinea

    Two 'Extinct' Mammals Species Have Been Discovered in New Guinea
    Mar 5 2026
    Episode 348 Thought extinct for 6,000 years, two marsupial species have been discovered alive in New Guinea. Biologists have found a new genus of marsupial glider and the Pygmy Long-fingered Possum on a small Western part of the island. One biologist said this discovery was “more important than finding a living Thylacine in Tasmania”. Host Rowan Hooper is joined by Tim Flannery of the Australian Museum in Sydney, who led the team that confirmed the discovery. He tells us all about these quirky and cute creatures, one of which is held up as sacred by some Indigenous communities - who won’t even utter its name in public. Learn about the glider’s habit of forming monogamous relationships and its gardening prowess. And discover why the long-fingered possum’s finger is so long. Other key players in this research are Professor Kris Helgen, multiple researchers from the University of Papua - and some of the local villagers.

  • How Ukraine Became a Drone Factory - and Changed Warfare Forever

    How Ukraine Became a Drone Factory - and Changed Warfare Forever
    Feb 27 2026
    Episode 347 Drones have taken over the battlefield in Russia’s war on Ukraine. Tens of thousands of drones are being produced every day - operating as kill vehicles for both sides. Multiple types are being deployed, including flying artillery drones and ground drones. Now the deadliest war since World War 2 - and considered the first “drone war” - the conflict is being fought in a way unlike we’ve ever seen before. With more than 80 per cent of military hits now made by drones. So on this special edition of the podcast we ask: is this the future of warfare? Driving these vehicles is in some ways like playing a video game, with operators sitting behind a screen with a handheld controller. And the gamification goes beyond this, with drone operators earning “points” for kills - that can be cashed in for more military equipment. AI is increasingly used to guide drones and to analyse targets. Joining hosts Rowan Hooper and Penny Sarchet are Matt Sparkes, who’s recently returned from a drone factory in Ukraine, and Serhii Andriev, Deputy Company Commander of “Kraken” 3rd Army Corps drone regiment. The team also hear from Andrii Hrytseniuk, CEO of Ukraine government organisation Brave 1 - and Trusta, an Ukrainian engineer and drone pilot trainer.

    The world is running out of water - can cloud-seeding save us?; Why some people get stuck in grief; Is our black hole actually a clump of dark matter?
    Feb 20 2026
    Episode 346 The world is running out of water, with many countries suffering from significant water shortages. We’re now having to rely on groundwater that takes thousands of years to replenish – so what can we do? One group says, to save us from worldwide “water bankruptcy”, we need to artificially change the weather. Although “cloud-seeding” has been around for a long time, a new technique is getting big results in the US. But the idea is becoming increasingly controversial – with cloud-seeding held responsible for recent floods in Dubai and Texas. So will this help, or hurt? Grief is a very normal experience for those who suffer a loss. But for 1 in 20 of us, this intense sadness doesn’t go away. “Prolonged grief disorder” was recognised as a distinct psychiatric condition in 2022 – but it was controversial, with some concerned we’re pathologising a normal human response. But new research suggests there really are unique things happening in the brains of those suffering from PGD. Could this help us find better ways to treat the condition? Is the black hole in the centre of our universe actually a massive clump of dark matter? It seems ridiculous to ask, but the new theory is genuinely worth investigating. Researchers say Sagittarius A* is just the right size that it could defy everything we think we know about it. Could we have an answer to the puzzle of dark matter, right on our doorstep? Hosted by Penny Sarchet and Timothy Revell, with guests Alec Luhn, Alexandra Thompson and Leah Crane.
