Ancient Human DNA Found in Stone Age Cave Art For First Time

Episode 380 The DNA of ancient humans has been found preserved in cave art that’s more than 40,000 years old. This discovery could open an entirely new avenue for finding out about the lives of our ancient ancestors. Researchers from the First Art project found these unexpected samples while examining 11 different caves decorated with rock art. Although it’s unclear if the DNA belongs to the original artist, it may soon be possible for researchers to identify the exact person who did the painting - and even uncover traits like their hair and eye colour. Now this has been done once, the potential for more discoveries is massive. We may even be able to figure out if Neanderthals were also making art like this. Rowan Hooper is joined by features editor Alison George and Genevieve von Petzinger at the University of the Witwatersrand in South Africa.

The Science of Football: Inside the 2026 World Cup

Episode 381 Advances in sports science, data analysis and AI are having a huge impact on the way football is played. With England rated highly in this year’s World Cup, and teams such as Paraguay causing upsets - how will science help give teams an edge? In the past there was very little data available to help assess player performance - and diet and training were much more rudimentary. But now we can analyse information in an incredibly sophisticated way, which is changing what players can achieve on the pitch. In this special World Cup episode recorded at the Royal Society in London, we explore the emerging role of data and AI in football, the neuroscience of penalty shootouts, the impact of extreme heat on player performance, differences between the men’s and women’s game - and much more. Rowan Hooper is joined by a panel of expert guests, including: Dr Charlotte Cowie, Chief Medical Officer of the British Olympic Association Dr Ian Graham, Founder of sports advisory business Ludonautics Holly Bridge, Professor of Neuroscience at University of Oxford To read more about these stories, visit https://www.newscientist.com/ Image credit: Ank Kumar, CC BY-SA 4.0 https://creativecommons.org/licenses/by-sa/4.0 via Wikimedia Commons Learn more about your ad choices.

A “Super” El Niño May Be Coming - Here’s What It Means

Episode 379 El Niño has officially arrived – a natural climate event that raises global temperatures. The difference this time is it looks very likely to become a “Super” El Niño. This is a more extreme warming phase which could lead to record high temperatures. Coupled with the ongoing impacts of climate change, weather agencies are predicting an increase in extreme weather events around the world. From droughts to floods and devastating coral bleaching, what will this year’s warming bring? We find out how a “Super” El Niño differs from a normal one, the extent of the damage it could cause and whether it’s responsible for the strange weather we’ve already had this year in the UK. Rowan Hooper and Penny Sarchet are joined by Emily Black, Climate Professor at the University of Reading and New Scientist climate journalist Alec Luhn.

Space 2075: How Humanity Will Live, Work and Make Drugs off-planet | Live Recording at the Royal Society

A special episode all about the future of space exploration, recorded in front of a live audience at the Royal Society in London. Earlier this year, the Royal Society published ‘The Space: 2075 report’, which recognises the huge changes we’re seeing in space exploration, and urges for action to be taken to make sure the next 50 years of activity in space is sustainable and benefits all of humanity. We brought together a panel of space experts to discuss the accelerated advances we’re seeing. Helen Sharman, the first British astronaut, blasted off Earth on a Soyuz rocket in 1991. She explains what it’s like to journey into space, the various ways it impacts the body and why humans still have the edge over robots for certain missions. Irene Di Giulio is a Biomedical Engineer at King's College London. She explores her work helping to get the first disabled astronaut to space and why it’s critical we push towards making space flight accessible. And Katie King is Co-Founder and CEO of BioOrbit, a pharmaceutical company which plans to make drugs in space. Discover why space is the perfect place to create drugs - potentially bringing at-home cancer treatments to the market. Hosted by Rowan Hooper and Abby Beall.

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.

Chernobyl 40 Years On: Legacy of the World’s Worst Nuclear Disaster

Episode 362 It’s been 40 years since the world’s worst nuclear disaster unfolded. Since the explosion at Chernobyl in 1986, the world has feared nuclear power - and the widespread damage it can do. But are we right to fear it? Though it’s left a lasting scar on the region, nuclear power is still safer than fossil fuels - which kill millions of people each year. So what will it take to change public opinion? We examine the lasting impact of nuclear fallout on Chernobyl - and how things have changed in the exclusion zone over four decades. Rowan Hooper is joined by New Scientist reporter Matt Sparkes, who shares news of his recent visit where he met the families who still live there. And Professor Jim Smith, author of Chernobyl: Catastrophe and Consequences, explains how the ecosystem and wildlife are thriving - and how he’s been making Atomik Brandy out of radioactive apples from the region.

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.

Weekly: How to finally get a good night’s sleep - with science

Episode 291 Who got better sleep - hunter-gatherers or modern-day humans? We’re constantly being told we’re in the midst of an epidemic of poor sleep, but were our ancestors spending any longer in bed than we are? The answer may well surprise you. We weigh up the pros and cons of sleeping in industrialised societies and explore the real reasons why we’re always complaining about being tired. We often hear you can’t make up for a bad night’s sleep - once you’ve missed those precious hours in bed, no amount of lie-ins will fix the damage. But is that true? We look into the surprising impacts on your brain from racking up just a few hours of sleep debt, plus tips on how to recover from it. And if you’re in sleep debt and don’t know it, we share the signs to look out for. Our microbiome is linked to various aspects of our health - and now it seems it shares a two-way connection with sleep. Irregular sleep patterns have been shown to boost the number of “bad” microbes living in our guts, so we unpack what’s going on. We also learn what supplements and foods you can use to improve your sleep, if cheese gives you nightmares - and whether a poop transplant can help you rest easier. Many people are using sleep trackers these days to improve their sleep habits, but how useful are they? Some experts say sleep trackers are doing more harm than good, making you so stressed about your sleep that you struggle to get any. The team shares their experiences with sleep wearables and other tech - everything from temperature controlled mattresses to EEG brain scanners. Naps can be good for you - if you do them the right way. Nap too long and you’ll end up feeling worse. So what’s the perfect amount of time to snooze in the afternoon? We dig into the science of naps, why the military recommends “tactical naps” and whether offices should be bringing in “nap pods” for staff. We also take a look at the strange practices of polyphasic sleeping, where you sleep in chunks throughout the day. Sleep special: https://www.newscientist.com/subject/sleep/ Chapters: (00:52) Are we really in a poor sleep epidemic? (6:22) Getting into sleep debt (16:47) How sleep affects your microbiome (25:36) Sleep trackers and other tech (29:28) Perfect the art of the nap Offering their sleep tips in this special episode of the podcast are Rowan Hooper, Madeleine Cuff, Catherine de Lange and Alison George.

The Wood Wide Web: The Forest Discovery That Sparked a Backlash

Episode 363 Suzanne Simard is a world-renowned forest ecologist who shot to stardom with her first book Finding the Mother Tree. It tells the story of her life’s work, showing trees and plants are connected through fungal networks, demonstrating a kind of wisdom and intelligence. Now, with the release of her latest book When the Forest Breathes, she’s keen to highlight the destructive and extractive forestry practices of the modern age - and why Western science needs an update. Rowan Hooper sits down with Simard under the famous Lucombe Oak in London’s Kew Gardens. Together they explore the concept of the ‘wood wide web’, the name given to her breakthrough work showing communication between forest trees via an underground fungal network. They discuss the scientific backlash that came when she popularised this work and how it all came at a particularly difficult time in her life. And they explore her time spent with indigenous peoples in the Amazon rainforest. As Simard aims to make us view forest ecosystems in a more holistic and regenerative way - what will it take to truly change the industry?To read more stories like this, visit https://www.newscientist.com/ Learn more about your ad choices.
