Suspended animation - the stuff of science-fiction, or a real-world solution to surviving long voyages into deep space? Actually it’s neither, but researchers have now successfully induced hibernation in mice and rats, suggesting that the same may be possible for humans... The team explores what this could mean for future medical treatments.Sand martins – known as bank swallows in North America - have returned to their breeding grounds. Ornithologist Bill Haines takes Rowan under his wing at the London Wetland Centre and introduces him to these remarkable tunnel-digging birds…Wharton earth…? New research shows that Wharton Jelly, the stem-cell-rich goo found in umbilical cords can have important therapeutic benefits for those suffering from certain autoimmune diseases. The team discusses its recent success in treating Type 1 Diabetes. The Clarion-Clipperton Zone, deep in the Pacific Ocean, is of great interest to biologists and industrialists alike, as it is home to thousands of previously-unknown marine species… and replete with the likes of nickel, cobalt, copper, titanium and rare earth elements. As Matt explains, many of these species could be lost to deep-sea mining before we have a chance to discover them all.Finally, the team discusses a major nuisance to lunar travel: moon dust! Moon landings will kick up millions of these tiny, razor-sharp particles, even blasting them out of lunar orbit where they could pose a risk to orbiting space stations. On the pod are Rowan Hooper, Chelsea Whyte, Michael Le Page, Alexandra Thompson and Matt Sparkes. To read more about the stories, subscribe at newscientist.com/podcasts.

The world is undergoing a catastrophic biodiversity crisis, and the UK is one of the most nature-depleted countries in the world. The problems are big, but there are solutions. On this special episode of the show, host Rowan Hooper reports from the Knepp Estate in southern England, a large estate owned by Isabella Tree and Charlie Burrell, who have become pioneers in the rewilding movement. Rowan spent the night wild camping in the beaver enclosure and being serenaded by nightingales. He speaks with Isabella and Charlie about their new book, The Book of Wilding; to beaver reintroduction expert Derek Gow about the magic of this keystone species, and to ecologist Andy Hector of the University of Oxford. To hear a livestream of the sounds of nature from Knepp, listen to Wilding Radio here.To read about subjects like this and much more, you can subscribe to New Scientist magazine at newscientist.com.

A new class of drugs that can reliably help you lose weight are generating great excitement in the fight against obesity - and Elon Musk and Hollywood actors have been using them too. Weight-loss scientists have developed hormone-mimicking injections that can reduce body fat by 20 per cent... and the team discuss how it works.  The world’s largest organism is not the blue whale. In fact, Pando the aspen grove in Utah weighs 35 times more than a blue whale and has lived for thousands of years. The team discovers why this incredible life form - a forest of genetically identical, connected trees - may now be at risk, and thanks to sound artist Jeff Rice, we get to experience how it may “hear” the world around it. We’ve all seen our sleeping pups run in mid-air as they dream of chasing squirrels, but did you know that octopuses dream too? And, as the team learns, by observing one very special octopus, scientists now believe they also have nightmares.Reaching out to aliens… could we trust them? The team discusses some of the concerns around making contact and suggests some fantastic reads on the subject.Always struggled with “Dry January”? Your prayers may finally have been answered. Sam Wong tests a new type of non-alcoholic drink… that still gets you tipsy. On the pod are Rowan Hooper, Clare Wilson, Michael Le Page, Alison Flood and Sam Wong.

Want to live 20 percent longer? Well, it may be possible in the future thanks to a new discovery. A life-extending mutation has been found in mice, and the team explains how its benefits can be transferred by transplanting blood stem cells. But will it work in humans?Cows’ burps are a big problem for global warming - but could kangaroo poo be the solution? We hear about a novel new idea to replace the bacteria in cows’ stomachs.A special kind of particle that can remember its past has been created using a quantum computer. The team explains the mind-bending qualities of this non-Abelian anyon, and how its creation could serve as a building block for advanced quantum computers.A new study has linked irregular sleeping patterns with an increased risk of death. The team finds out what’s going on.Climate change may have broken a link between desert grasslands and the Pacific Ocean. We learn how this severed connection is impacting biodiversity in North America’s Chihuahuan desert.On the pod are Chelsea Whyte, Sam Wong, Michael Le Page, James Dinneen, Alexandra Thompson and Alex Wilkins.
