#66: Sea level rise; Bitcoin carbon pollution; how to measure self-awareness
The most detailed analysis yet of global warming and sea level rise has been published. The paper’s lead author, Tamsin Edwards of King’s College London, explains that we now have a better understanding of the consequences of missing the 1.5 degrees target of the Paris Agreement. Later the team gets introspective as they learn about metacognition, and how brain scanners are now able to measure self-awareness: learn how to boost your own self-awareness here. They discuss how the digital currency Bitcoin will soon create more carbon pollution than the whole of Sweden. And they explain how the naming of a new species of ant has been used to champion gender diversity, and share some amazing findings about the crew from the wreck of Henry VIII’s warship the Mary Rose. Also, make sure to check out this piece from Jemma Wadham who spent two weeks living under a glacier in Norway. On the pod are Rowan Hooper, Tiffany O'Callaghan, Cat de Lange, Karina Shah and Matt Sparkes. Hosted on Acast. See acast.com/privacy for more information. Learn more about your ad choices.

#65: Chernobyl radiation safety; Chinese space station; wisdom of trees
It’s been 35 years since the devastating explosion at the Chernobyl nuclear power plant. But new research shows there has been no increase in genetic mutations in people who worked to clean up the accident site, nor in their children. The team discusses communicating safety risks around radiation with the director of the Chernobyl Tissue Bank, Gerry Thomas. The team then talks about two stories in space exploration news, with another SpaceX launch to the ISS, and the start of the construction of a new Chinese space station. We also hear from legendary biologist Suzanne Simard. Simard discovered the wood wide web - revealing that trees live in a connected society, trading, collaborating and communicating in sophisticated ways through a shared underground network. The team also discusses a rapid rise of covid-19 infections in India, and they dig into the discovery of ancient structures in Arabia which predate Stonehenge and the Pyramids. On the pod are Rowan Hooper, Tiffany O'Callaghan, Michael Le Page, Leah Crane and Ibrahim Sawal. Hosted on Acast. See acast.com/privacy for more information. Learn more about your ad choices.

#64: Earth Day rescue plan: climate change and biodiversity special
To mark Earth Day 2021, we’ve assembled a panel of experts to discuss climate change and biodiversity loss - “two runaway crises tightly interlinked that will mutually make each other’s effects worse”. New evidence shows 2021 really is a make-or-break year for the environment and the planet. In this episode the panel explores the disparity between our efforts to combat each issue, they explain how some attempts to help the environment can actually worsen the situation, and they discuss the limitations of carbon drawdown technologies. The discussion leans into the dangers of losing the Amazon rainforest, the importance of working with local communities, and the role billionaires play in advancing global climate goals. And while the scale of the problem seems insurmountable to many, the team says it’s important to remember that your actions are not futile - taking a personal stand and changing your habits is still absolutely critical. The Earth can recover, if we let it. On the pod this week: New Scientist journalists Rowan Hooper, Michael Le Page and Adam Vaughan, joined by Tilly Collins from the Centre for Environmental Policy and Bonnie Waring from the Grantham Institute for Climate Change and the Environment.

#63: Musical spider’s webs; magic mushrooms for treating depression; the sound of coronavirus
The vibrations of a spider’s web have been transformed into some spectacularly haunting pieces of music. The team shares the work of MIT researcher Markus Buehler, which gives us a glimpse into what life is like for a spider. The team then discusses new research suggesting psilocybin, the psychoactive component of magic mushrooms, might be an effective way of treating depression. The theme of sound continues as the team shares the work of molecular biologist and composer Mark Temple, who’s turned the genetic sequence of the coronavirus into beautiful and ethereal music. On top of this, the team brings news of a robot with an artificial nervous system that’s learnt to catch a ball, and they celebrate a new discovery about the world’s oldest animal, the comb jelly. On the pod are Rowan Hooper, Chelsea Whyte, Sam Wong and Donna Lu. To read more about all these stories, subscribe at newscientist.com/podcasts.

#62: Synthetic life; rescue plan for Earth; muon g-2 new physics
Scientists tinkering around with the creation of synthetic life have taken a significant step forward. The team explains how synthetic cells could one day be implanted in humans. Alongside this is the news that researchers have used frog skin cells to create a microscopic living robot, which can heal and power itself. As levels of CO2 in the atmosphere reach a record high, the team looks at ways to join up global efforts in tackling both the climate and biodiversity emergencies. They discuss another challenge to the Standard Model of particle physics, as Fermilab’s muon g-2 experiment threatens to shake up everything we thought we knew. And finally the team explains how the asteroid that killed the dinosaurs gave rise to the Amazon rainforest, and explore news of rare blood clots linked to the AstraZeneca coronavirus vaccine. On the pod are Rowan Hooper, Tiffany O’Callaghan, Layal Liverpool, Richard Webb and Krista Charles. To read about these and much more, subscribe at newscientist.com/podcasts. Hosted on Acast.

#61: Worse allergies; black hole in our backyard; new flavours of vanilla
Spring has sprung and… ACHOO!! Yep, hay fever is back with a vengeance. This week the team has some bad news for hay fever sufferers, as allergies are set to get worse (in every way imaginable) because of climate change. The team then ramps up the excitement with the news that there may be an ancient black hole sitting on the edge of our solar system, which might actually be within our reach! They discuss vanilla’s attempts to break free of its ‘boring’ stereotype, as growers begin to experiment with new and exciting flavours of the classic taste. As countries around the world prepare for a third wave of covid-19 infections, the team explains how the vaccine rollout will impact hospitalisation and death rates. And they also celebrate the Octopus, as new research suggests they might be able to dream. On the pod are Tiffany O’Callaghan, Graham Lawton, Stuart Clark and Clare Wilson.

#60: New physics; anti-ageing human embryos; Mars update
The Large Hadron Collider might, just might, have found something that challenges the Standard Model of particle physics. The team hears why an anomaly concerning a quark could hint at a crack in our understanding of physics. They also find out whether the age-defying, rejuvenating properties of human embryos can help us reset the ageing process in adults. As the Perseverance rover has been on Mars for a month now, there is of course more news from our neighbouring planet, namely new recordings from the surface to listen to, and the upcoming launch of the Ingenuity helicopter. Also on the pod is the worrying story of vaccine hesitancy in the EU, and the team celebrates a microbe unlike anything seen before. On the pod are Rowan Hooper, Tiffany O’Callaghan, Layal Liverpool, Richard Webb, Chelsea Whyte and Leah Crane. To read more about the stories, subscribe at newscientist.com/podcasts.

#59: Vaccine success; hibernation and anti-ageing; world’s first computer
We’re tantalisingly close to resuming normal life, as promising news from Israel has shown that vaccines are swinging the fight against covid-19 in our favour. But we’re not out of the woods yet - the team explains why it’s still too risky to completely lift restrictions. They also discuss great news if you love your beauty sleep! It turns out when marmots hibernate the ageing process slows down dramatically, which is going to be useful as we develop ways to put humans into hibernation. The pod also tackles the mystery of the Antikythera mechanism, a 2000-year-old cosmos decoding device often called the world’s first computer. And they explain how mushrooms might be the answer to our clean energy needs, and chat to author and podcaster Dr Helen Scales about her new book ‘The Brilliant Abyss’. On the pod are Rowan Hooper, Tiffany O’Callaghan, Jo Marchant, Eleanor Parsons and Michael Le Page. To read more about the stories, subscribe at newscientist.com/podcasts. Hosted on Acast.

#58: Covid good news; cold water swimming; quantum unreality
This week: relief and joy for people in the US, with the news that those who’ve had two doses of vaccine will be allowed to meet up inside with friends and family. The team also discusses the exciting news about how the vaccine might help people with long covid. Things take a turn for the weird when the team explains just how little we know about reality, certainly from a quantum mechanical point of view - but Carlo Rovelli might have an answer. They also explore why cold water swimming is so good for us, they find out how we can use light to power spacecraft, and they celebrate the wondrous sea slug, which has a penchant for chopping off its own head. On the pod are Rowan Hooper, Tiffany O’Callaghan, Clare Wilson, Alison George and Richard Webb. To read more about the stories, subscribe at newscientist.com/podcasts. Hosted on Acast.

#57: Moon base; Neanderthal speech; Elizabeth Kolbert on geoengineering
Ever looked up at the Moon and thought “I could live there”? Well… this week we hear how Chinese researchers have managed to make an almost completely self-sustaining base on Earth which could be replicated on the lunar surface. They’re also joined by Rebecca Wragg Sykes, the author of ‘Kindred: Neanderthal Life, Love, Death and Art’, who explores new evidence suggesting the extinct humans may have had the power of language and speech. Pulitzer-prize winning environment reporter Elizabeth Kolbert also joins the pod to talk about her new book ‘Under a White Sky’, and whether environmental fixes like geoengineering will help or harm our efforts to address climate change. In the mix is a brand new theory for creating a working warp drive, and new research looking at human friendship. On the pod are Rowan Hooper, Tiffany O’Callaghan and Michael Le Page.
