The Male G-Spot Has Finally Been Found

2026/04/06

Episode 358The male G-spot exists - and scientists have found it. The most comprehensive study of the human penis has identified one specific location most involved in sexual pleasure - and it’s not what science thought. 14 penis slices from deceased donors were inspected under the microscope - and one region in particular was packed with nerve endings. Medical literature has long thought a different region was home to the most nerves, but this new finding debunks the old textbooks. Now we know

Episode 357A global food shock is on the way because of the ongoing war in Iran. Your food bill is expected to rise significantly. The conflict is showing just how fragile our food system is, as spikes in fuel, fertiliser and pesticide prices begin to have knock-on effects around the world. With food availability in jeopardy, should we be stocking supplies at home? Coupled with the worsening climate and environment crises - and governments increasingly incentivising the production of biofuel -

2026/03/27

Episode 356A truck carrying antimatter has been driving around the campus at CERN, home of the Large Hadron Collider. But why are scientists transporting this delicate and extremely expensive substance? Antimatter is regular matter’s counterpart, first theorised in the 1920s. Producing and storing it has proved difficult, as it’s prone to annihilating the moment it meets its opposite half. But CERN scientists found a way - and it’s the only facility on Earth able to create these

2026/03/25

Episode 355 An entire pig’s brain has been preserved after death, using a technique that will keep the structure of the brain intact - potentially for hundreds of years. Scientists say they will offer the treatment to terminally ill humans, in the hopes that one day, in the distant future, we’ll be able to reconstruct their minds and bring them back to life. Because of the speed at which scientists need to preserve the brain tissue, the method will only work on people who opt in for assisted

The Dangerous Bias Shaping the Future of AI

2026/03/23

Episode 354 Women are being erased from AI technologies. When world-changing technology is built primarily by men, the impact for women is hugely damaging. This was the focus of a recent conference at the Royal Society in London. Panellists discussed how women are being left out of this major tech revolution, with Silicon Valley becoming increasingly hostile towards them. And as the conversation increasingly shifts to the existential risks of artificial intelligence, some argue the focus is

Episode 353The world might feel dark right now, but life is actually getting better, rapidly. From the rise of feminism and antiracism to environmental movements and shifting understandings of gender, the Western world looks nothing like it did 75 years ago. Yet despite so many historic victories for rights and ideas in recent times, it often feels like we’re living in dark times - with progress that’s stalling or going backwards.

Episode 352Notwithstanding President Trump’s efforts to slow the growth of renewable energy, the US/Israeli attack on Iran has given the green revolution a huge boost. In response to the war in Iran, the Islamic Republic has stopped almost all traffic in the Strait of Hormuz, a waterway through which one-fifth of global oil and one-fifth of seaborne gas supplies pass. They’ve also struck oil and gas fields with drones and missiles. This has given countries a much-needed wake-up call, showing

Episode 350 What If Alzheimer’s disease starts in the body, not the brain? A radical new theory upends everything we thought we knew about the disease. Alzheimer’s is the most common form of dementia - the leading cause of death in the UK. And for 100 years we believed it all happened in the brain. Despite all of the major symptoms of Alzheimer’s being brain related, scientists studying gene activity have discovered something surprising. Most risk variants for the disease appear in the skin, lungs

Episode 349One of the most vital systems of ocean currents - needed to keep life in northern Europe stable - is at risk of collapse. And now we can predict when it’s going to happen. Thanks to the work of climate scientists, we now have a model that tells us when major shifts in the Atlantic Meridional Overturning Circulation (AMOC) are expected. The AMOC is the Atlantic conveyor belt that keeps northern Europe temperate. If it turns off, northern Europe would be plunged into freezing conditions

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

Episode 347Drones 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

Episode 346The 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

Episode 345More than 8,500 years ago, ancient people crossed the ocean to the remote island of Malta for the first time. Long before compasses or sails were invented, these prehistoric people navigated the seas on logs, using the stars to travel vast distances. Recent findings show we’ve long underestimated the voyaging capabilities of stone-age hunter-gatherers. We discuss the many examples of ancient travel - and what this all tells us about the ancient mind. Could just one hour of brain

Episode 344Elon Musk has announced he wants to merge SpaceX with another of his companies, xAI, and launch one million satellites into space. One reason - according to Musk - is to eventually harness the entire power of the sun, a sci-fi sounding idea that would make us a Kardashev Type II civilisation. But he also wants the satellites to help power AI and move data centres off Earth. Is his goal realistic… and what would be the consequences? Parents desperate to get their children to sleep are

Episode 343The task of growing human brains in a lab has taken a step forward. Scientists have been creating brain organoids since 2013, but have now grown blood vessels in them for the first time. These mini brains resemble the developing cortex - the area of the brain that thinks, feels and stores memories. These advancements will help us learn more about the brain and conditions like dementia. But what if we go too far and they become conscious? Geoengineering is being talked about more and

Episode 342Social media began with the best intentions - but it soon went sour. Platforms that once fostered connection are now driven by an endless desire to monopolise our time. From the endless scroll to ragebait content, social media is no longer designed to connect us with friends and family - but to profit from our attention. And that’s not to mention the damaging political influence it can have. As countries and governments move to act against it, is there a good solution to these

In Moral Ambition, the Dutch historian and the best-selling author argues that smart people need to stop wasting their lives in “BS” jobs - and turn their skills to causes that benefit humanity.

Episode 340Acquiring Greenland has been deemed a national security priority by America. President Trump wants to use the country to deter adversaries in the Arctic, have control over its rare minerals and oil - and maybe even build experimental cities. But with the challenges of a changing climate, difficulty actually extracting any natural resources and the fact that Greenland isn’t free to occupy, how realistic are Trump's goals?

If it goes well, it’ll set the stage for a lunar landing by Artemis III - bringing us closer to creating permanent settlements on the surface. And that’s not all - SpaceX is planning to visit Mars this year as part of its plans to colonise the Red Planet. Plus, in May we might see the launch of a new American space station.
