#195 Breakthrough in suspended animation; treatment using stem cells from umbilical cord; moon dust threat

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.

#194 Rewilding special: a night in the beaver pen at the rewilded Knepp Estate

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.

#193 Drug that could cure obesity; world’s largest organism; octopus dreams; mood-enhancing non-alcoholic drink

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.

#192 Life-extending mutation; Kangaroo poo transplant for cows; irregular sleep linked to increased risk of death

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.

#190 Problems for lab-grown meat; do we need vitamin D supplements?; waking the sleeping Arctic ocean; fish sing for Eurovision

Lab-grown meat may be cruelty free, but is it really better for the environment? Not at the moment. In fact, the team finds out how it’s up to 25 times worse than normal meat. And with prices still astronomically high, will it ever become a viable replacement?Are we waking up the sleeping Arctic ocean? Melting sea ice from rising global temperatures is having a knock on effect on one of the Arctic’s major ocean currents, the Beaufort Gyre. Rowan speaks to earth scientists Harry Heorton and Michel Tsamados of University College London, authors of a new paper looking at the changes to the gyre. Rowan asks them whether we’re approaching a climate tipping point where changes become self-perpetuating and irreversible.In the unlikely event that you have ever wondered what a church organ would sound like if it was played on another planet - wonder no more!

#187 CultureLab: The Power of Trees with Peter Wohlleben

As humans are responsible for the devastation of the world’s forests, surely it’s our job, then, to step in and make things right? Well, not according to German forester and best-selling author Peter Wohlleben.In his latest book ‘The Power of Trees’, he argues that forestry management, tree planting, and the exploitation of old growth forests is ecologically disastrous, and that trees and forests need to be left to heal themselves.In this episode of CultureLab, New Scientist culture and comment editor Alison Flood asks Peter about the book, and why he believes forests have the capacity to deal with climate change on their own.To read about subjects like this and much more, you can subscribe to New Scientist magazine at newscientist.com.

#186 Private space company crashes on the moon; hypnotherapy as anaesthetic; record-breaking ocean warming; Rosalind Franklin and DNA

With SpaceX’s Starship blowing up, and ispace’s lander crashing into the moon, in the last week two of the most exciting missions of the year have failed. The team finds out what went wrong, and how long it’ll be until these missions can try again.Fish farts and genital stridulation - the team shares a beautiful underwater soundscape of British ponds, recorded using a hydrophone. They learn about the daily acoustic activity cycles of ponds, and find out why researchers are collecting these sounds.Hypnosis is becoming a more mainstream part of surgery, with patients being eased into operations with suggestive language and calming phrases. The team finds out how it’s helping to supplement normal anaesthetics, reducing pain and anxiety.2024 may be the year we breach 1.5 degrees of global warming. Despite dramatic weather events over the last few years, the Earth has actually been in a cooling period called La Niña. So as we enter an El Niño, a period of warming, the team says we should brace for more intense, record-breaking heat. It comes as ocean warming hits new, and very concerning highs.Was Rosalind Franklin really the “wronged heroine” of DNA? Did Francis Crick and James Watson really swindle her out of her share of the credit for the breakthrough discovery of DNA’s double helix structure? That’s what Watson’s famous book ‘The Double Helix’ would have you believe. But Rowan speaks to biologist Matthew Cobb who sheds new light on what really happened.On the pod are Rowan Hooper, Leah Crane, Madeleine Cuff and Clare Wilson.
