A “Super El Niño” Is Coming - And It Could Trigger Global Climate Chaos

Episode 361 The Earth is about to enter an extremely strong climate phase that could cause major disruption on a planet-wide scale. This “super El Niño” - or “Godzilla El Niño” - threatens to make 2027 the hottest year on record. If it’s as strong as scientists fear, the weather event will bring droughts to some areas of the world and floods to others, causing food shortages and billions of pounds of damage. And with the world already warming faster due to human activity, the effects will only be intensified. To discuss what we can expect from the near future, Rowan Hooper and Penny Sarchet are joined by New Scientist climate reporter Alec Luhn.

Britain’s First Astronaut on the New Race to the Moon | Helen Sharman

Episode 360 A new era of space travel is finally upon us. NASA’s Artemis II rocket successfully launched 4 astronauts around the moon and back. Reacting to the historic news is Britain’s first astronaut, Helen Sharman. The high tech space race sees countries, once again, scrambling to be the first to land people on the lunar surface - but this time to set up a permanent base of operations. Artemis II has now tested the capabilities of the space craft. But Artemis III and IV are already in the works, with dozens of other launches planned, to get cargo and rovers to the moon. Unlike the space race of the 1960s, this one is very clearly between the US and China. And it’s clear that no matter who lands first, each country will continue their efforts to reach the surface and benefit from the so-called “lunar economy”. Rowan Hooper and Helen Sharman reflect on the success of the launch, nervousness about the spacecraft’s heatshields on reentry - and what it all signals for the future. She also explains why we need cooperation now, more than ever, to ensure international collaboration when we do finally start building on the lunar surface.

Genetic analysis reveals how the Neanderthals went extinct

Episode 359 DNA analysis of 10 Neanderthal people is shedding light on why their populations declined 75,000 years ago - eventually leading to their extinction. After being hit by a cold spell, we can see Neanderthals lost a lot of genetic diversity as their numbers dwindled. Living in small, isolated groups, we see evidence in both genetic and archaeological evidence that this pushed the human species to die out. One exception to this trend is Thorin - known as the last Neanderthal. We explore why his tribe may have been able to cling onto existence for longer than the rest of their species. It wasn’t long ago this kind of understanding about ancient human species was well out of reach. Now the field is moving forward rapidly. What will we find next? To discuss this new finding - and to look at the genetic history of interbreeding between humans and Neanderthals - Rowan Hooper and Penny Sarchet are joined by Alison George and Michael Marshall.

The Male G-Spot Has Finally Been Found

Episode 358 The 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 the ‘frenula delta’ is the male g-spot, what can this teach us about male sexual health? To discuss this, Rowan Hooper is joined by New Scientist Australia reporter Alice Klein.To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices.

Food shock is inevitable due to the Iran war – and it could get bad

Episode 357 A 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 - there could be tough times ahead. So how can we prepare? From eating less meat and raising less livestock, to countries focusing on renewable energy and becoming more self-sufficient - will this shock finally be what’s needed to force leaders to take action? To discuss this critical issue, Rowan Hooper is joined by climate, energy, and food systems professor Paul Behrens - and New Scientist reporter Michael Le Page.

Rebecca Solnit On Why the Future Isn’t as Dark as It Looks

Episode 353 The 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. In her new book, The Beginning Comes After the End: Notes on a World of Change, writer and activist Rebecca Solnit explores how for decades social movements reshaped the world in ways we often fail to notice. Solnit argues that we are witnessing nothing less than the slow dismantling of an old worldview. And it’s time we pay attention. Rowan Hooper speaks to Solnit about the power of a good story, our growing understanding of the interconnectedness of nature and humanity - and why recognising progress may be essential to shaping the future.

World’s First Antimatter Truck Carries Most Valuable And Volatile Substance on Earth

Episode 356 A 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 particles. Carrying just 92 antiprotons, this truck experiment is the first step in setting up an antimatter delivery service, allowing scientists to send little pieces of antimatter on trucks to labs around Europe. To discuss why an antimatter delivery service is even needed, Rowan Hooper and Penny Sarchet are joined by Alex Wilkins, who recently visited the lab and saw the antimatter factory in person. We also hear from the new director-general of CERN, Mark Thomson. To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices. Visit megaphone.fm/adchoices

How ancient humans crossed the vast ocean; Brain training for dementia; Life of science legend Maggie Aderin

Episode 345 More 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 training a day be enough to stave off dementia? For the first time, an intervention against dementia has been tested in a randomised control trial. Lasting an impressive 20 years, participants in the trial played a brain training game for just a few hours a week - and the results were remarkable. The legendary space scientist Maggie Aderin joins the show to discuss her new book, Starchild: My Life Under the Night Sky. The Sky at Night presenter discusses her motivation for writing a memoir, how her love of astronomy came about, what it was like as the only Black woman in her university class, her time working on the James Webb telescope - and more. Hosted by Rowan Hooper and Penny Sarchet, with guests Maggie Aderin, Michael Marshall and Alexandra Thompson.To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices.

Scientists Can Now Preserve a Brain After Death - What’s Next?

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 dying. But will we ever be able to digitally upload and reanimate a brain, or is this just offering false hope to those already suffering? And if we do develop the technology, what kind of world will these people wake up to? To discuss this new method, the ethics and science of consciousness, Rowan Hooper and Penny Sarchet are joined by Alexandra Thompson and Thomas Lewton.To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices.
