Climate 2026: Record Heat, Tens of Thousands Dead, Mass Evacuations
Episode 389 Europe is burning through another summer of extreme heat. Temperatures are soaring across the continent, wildfires are forcing mass evacuations in France and Spain, and scientists warn that heatwaves are becoming more frequent, more intense and longer-lasting as the climate warms. The fires are changing too. Hotter, drier conditions are creating larger and more destructive wildfires. Some are even generating their own weather systems, pyrocumulonimbus thunderstorms, in regions we’d never seen before. Find out what is driving Europe’s escalating heat and wildfire crisis, and whether district cooling networks could help cities stay livable in a much hotter future. Rowan Hooper and Penny Sarchet are joined by Alec Luhn and Michael Le Page.

Scientists Pioneer Surgical Methods for Human Head and Eye Transplants
Episode 388 Two extraordinary breakthroughs have been made in transplant surgery. First, scientists have found a way of keeping human eyes alive for up to 10 hours after death, opening up the possibility of eye transplants in the future. And in a second controversial surgery, another team has managed to restore severed spinal cords in pigs, allowing them to walk again after being paralysed. While it’s hoped this will eventually allow people with spinal injuries to walk again, one of the scientists involved is a proponent of human head transplants - or body transplants as they should really be known. Is that the ultimate goal? Find out how the scientists achieved these feats - and what’s required to take both surgeries to the next level. Rowan Hooper and Penny Sarchet are joined by Alexandra Thompson. To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices. Visit megaphone.fm/adchoices

The Most Promising Alien Planet We've Ever Found?
Episode 387 Two big interstellar discoveries have hit the headlines. One is the discovery of the first atmosphere ever found on a small, rocky exoplanet that could host alien life. The planet LHS 1140b is about 50 light years from Earth and sits in the “Goldlocks” zone, meaning it’s close enough to its star to be habitable. So what do we know about its atmosphere – and could it be just like Earth? The second story is of sugar molecules discovered in interstellar space for the first time – detected in a cosmic cloud nearly 27 light years away. Researchers believe this sugar could have formed before the solar system itself. Find out more with Senior Editor Chelsea Whyte and Space Reporter Leah Crane.

Climate Crisis Is Triggering Global Food Shortages - New Predictions Are Devastating
Episode 386 The climate crisis is having a significant impact on yields of crucial food crops. Losses of maize, wheat and soybeans alone are costing $20 billion a year due to heat and drought. New estimates expect this to rise to $160 billion per year by 2100 - although that could be an underestimate. While this means food prices will keep on rising in developed countries, the majority of the population in the world’s least developed regions work in farming, so crop losses have the potential to destabilise them, creating social unrest and increased migration. But beyond getting emissions under control, do we need to completely rethink how we produce food globally in order to combat this? Rowan Hooper and Penny Sarchet are joined by Michael Le Page to discuss this new prediction and the action needed to stop it coming true.

7 Essential Lessons We Can Learn From Homer’s Odyssey
Episode 385 What can Homer’s Odyssey teach us about psychology and human nature? Locked up in this 2,500-year-old text are a host of profound lessons and ancient wisdom. In her new book The Odyssey Mindset, Oxford classicist and clinical psychologist Sam Akbar draws on seven essential lessons from this classic piece of Greek literature. She showcases what it teaches us about issues like grief, ego and dealing with trauma - translating The Odyssey into a toolkit for modern life. The book is out just as Christopher Nolan’s film The Odyssey hits the big screen. So if you want to have a deeper appreciation of Homer’s work before you visit the cinema, this one’s for you. Rowan Hooper speaks to Sam Akbar about the incredible influence this work has had on Western culture, and Homer’s lessons for clinical psychology.

Chris Packham on the Untold Story of Evolution
Episode 384 The story of evolution is being brought to life in a new way. BBC series Evolution tells the story of 5 iconic animals, from elephants to ostriches, using CGI to reimagine ancient fossils. And this isn’t just about the animals that came before them, but also explores the intricacies of how locomotion, intelligence, feeding, and reproduction emerged. The series is hosted by broadcaster, natural history legend, and New Scientist superfan Chris Packham, who hopes Evolution will remind viewers that we are all connected on a deep and fundamental level. Penny Sarchet sits down with Chris to discuss why they've chosen to tell the story in this way and explore some of his series highlights.

Heatwaves Are Getting Deadlier - And It’s Going To Get Worse
Episode 383 As another heatwave takes hold, figures are now showing just how deadly the last one was. With one early estimate suggesting as many as 25,000 people may have died in Europe as a result of June’s extreme heat. Heatwaves across Europe, Asia, Australia and the US hit record highs last month and wildfires are now spreading across southern Europe. And as the effects of climate change increase the intensity year on year, can we be better prepared for the next ones coming our way? In this episode we discuss the urgent need to adapt homes and infrastructure to deal with a warming climate, the impact of extreme heat on the human body - and how you can become better adapted for the coming hot weather. Rowan Hooper and Penny Sarchet are joined by New Scientist reporters Michael Le Page and Alec Luhn.

Breakthrough Synthetic Cell Has Just Reproduced - But Is It Alive?
Episode 382 Scientists have created a synthetic cell with just 36 genes that can copy DNA and replicate. In an attempt to create a “minimal cell”, a team led by professor Kate Adamala have built “SpudCell” from the ground up, using non-living components. But is it alive - and is it dangerous? Despite being able to carry out some of the tasks of a normal cell, it’s not clear that it’s capable of evolution - yet. But it is a major breakthrough in the field and could pave the way for the creation of artificial life in the future. Researchers have made their work open source so the next breakthrough can be fasttracked - and hope it will help provide a solution to the climate crisis by replacing the need for petrochemicals. To discuss the news - and its implications for the origin of life - Rowan Hooper and Penny Sarchet are joined by New Scientist reporter Michael Le Page.
