S1 Ep 170#170 How Venice is confronting climate change and adapting to the rising seas
Venice, Italy, is often voted the world’s most beautiful city. Built across 120 small islands in a shallow lagoon, it’s been an important financial and cultural centre for over a thousand years. But it faces an existential threat from sea level rise caused by climate change. Rowan Hooper visits the city’s new water defence system – a €6 billion sea barrier designed to defend Venice against high tides. But what does the barrier mean for the ecology of the lagoon, and what about people living on coasts around the world who don’t have the protection of a sea wall or barrier? In a special episode of the podcast, Rowan discusses these issues with Ignazio Musu, professor of environmental economics at Venice International University, and Swenja Surminski, professor of climate adaptation at the Grantham Research Institute at the London School of Economics.

S1 Ep 169#169 Why the US is shooting down UFOs; the science behind period cravings; saving the UK’s rivers
The UK’s rivers are in a dire state. Full of sewage, chemicals and prescription drugs, life in our rivers is suffering. New Scientist has teamed up with the i newspaper to launch the Save Britain’s Rivers campaign to raise awareness of the issue and get changes in the law. The team explores the problem, which includes question marks over illegal activity, and explains the aims of the campaign. UFOs are on our radar, quite literally, as US fighter jets have suddenly been tasked with blowing them out of the sky over North America. But why now? The team explains how this hunt for flying objects was started by a suspicious Chinese balloon. Can love be measured? While we may never figure out exactly what it is, a team of researchers has come up with a way of measuring where in the world people are most loved-up. From a list of 45 countries, the team shares the official winners and losers. Did you know there may be an evolutionary advantage to having curly hair? The team shares the findings of the first study to examine hair type from an evolutionary perspective. Why do some women get cravings for certain foods during their period? The team discuss a study of cis-women suggesting that inflammation could key us into what’s going on, and why cravings vary. Also, don’t miss our investigation of the vaginal microbiome - what an ecosystem! On the pod are Rowan Hooper, Penny Sarchet, Graham Lawton, Alice Klein, Jeremy Hsu, Alexandra Thompson and Daniel Capurro.

S1 Ep 168#168 Polar Sounds: Rare underwater noises from the Arctic and Antarctic
Hear the chattering sounds of a narwhal, the surprisingly tuneful tones of singing sea ice, and the alarming crashes of ice shelves collapsing in this special bonus episode of the podcast. These rare noises, captured by hydrophones in the Arctic and Antarctic, paint a fascinating image of two of our planet’s lesser-known regions. Rowan Hooper catches up with Stuart Fowkes, the founder of Cities and Memory, one of the world’s biggest sounds projects, which has joined forces with scientists and musicians to present these sounds, and to interpret them.

S1 Ep 167#167 Bird flu in mammals, the cause of sunquakes, and the entropy of consciousness – the latest news in science
The continuing avian flu epidemic is devastating bird populations. And now there are concerns over increasing numbers of mammals becoming infected. As reports rise, the team finds out whether this strain of bird flu may begin to pose a bigger threat to humans. Everyone’s jumping on the AI chat bandwagon. As ChatGPT continues to make headlines, two big companies have just announced their contributions to the field. The team explains how both Google and Baidu are looking to change search engines as we know them with their AI models Bard and Ernie. A new discovery has advanced our understanding of consciousness. It turns out that our brains produce less entropy when we’re asleep than when we’re awake. The team explains what’s going on. Mysterious sunquakes may be caused by weird beams of electrons from solar flares. It’s long been debated whether flares could cause these ripples on the Sun’s surface, but the team looks at new research on the connection between the two. A collection of rarely heard sounds recorded in the Arctic and Antarctic have been released as part of a project called Cities and Memories. The team shares the Clanger-like whistles of weddell seals and the chain-sawing sounds of crabeater seals. If you like what you hear, there’s a bonus episode coming up with loads more sounds. On the pod are Penny Sarchet, Timothy Revell, Matt Sparkes, Madeleine Cuff and Karmela Padavic-Callaghan.

S1 Ep 166#166 Immune systems: Is yours weak or strong and how can you boost your immune system to fight disease?
The immune system is the intricate constellation of cells and molecules in our bodies that defends us against disease and on this special bonus episode of New Scientist Weekly we delve into the latest science on how the immune system works. Why do some people never seem to get ill? What was the effect of covid lockdowns on our immune system? Is it really possible to boost your immune system through eating certain foods? Do you have a naturally strong or weak immune system? And how can we engineer the immune system to seek and destroy cancers that have evaded treatment? Discussing these issues are New Scientist journalists Rowan Hooper, Helen Thomson, Penny Sarchet and Michael Le Page. These stories and much more are explored in a special edition of New Scientist magazine, also available to download on our app. Hosted on Acast. See acast.com/privacy for more information.

S1 Ep 165#165 Water dowsing to detect leaks; Astroforge going asteroid mining; AI discovers new bacteria-killing proteins – the latest news in science
An ancient and debunked method of searching for water leaks is still being used by some of the UK’s water companies. The team finds out why water dowsing is still in practice, despite being scientifically discredited. But they also find out how it might actually work - just not in the way you think. People have sometimes complained that the chimps in the various Planet of the Apes films have unrealistic eyes - because they have whites around the iris, like humans. But it turns out real chimps actually do have whites too. We thought this white sclera was only a human thing - but as Rowan finds out, we were wrong. An artificial intelligence called ProGen has designed bacteria-killing synthetic proteins, some of which actually work when inserted into cells. The team suggests this is a “short-cut to evolution” and is very promising for the development of new antibiotics. Asteroid mining tech is being tested in space in April by satellite construction company AstroForge. Rowan speaks with their co-founder to hear what they’re hoping to achieve, and discusses the company’s second mission planned for later this year, when they’ll be doing a flyby of a near-Earth asteroid to look for platinum. If you look up at the sky you may just see a rare green comet flying by. Comet C/2022 only heads this way every 50,000 years, so the team explains how you can seize the opportunity to see it for yourself. On the pod are Rowan Hooper, Penny Sarchet, Matt Sparkes, Abby Beal and Karmela Padavic-Callaghan.

S1 Ep 164#164 The Last of Us: the science of a fungal zombie apocalypse
The new HBO series The Last of Us is making waves, raking in a steady stream of high reviews. Based on a game of the same name, it’s set in a world where a parasitic fungus called Cordyceps has mutated to infect and zombify humans. In this bonus episode of the podcast, Bethan Ackerley asks if this could actually happen in real life. She’s joined by fungal pathogens expert Professor Matthew Fisher of Imperial College London.

S1 Ep 163#163 Antidepressants; Exoplanets; California’s megadroughts – the latest news in science
A vaccine for the respiratory virus RSV may be ready this year. In fact, after decades of efforts, successful vaccines have arrived like buses, with three of them on the way. As a particularly devastating virus for young children and the elderly, the team explains just how impactful these new vaccines will be. You may have read headlines that Earth’s core is changing direction - but the team explains why it’s not all it’s cracked up to be. They also bring less-than-thrilling news for the existence of life in the universe, as we may have been overestimating how many planets are out there that have the right conditions for life. Following intense rainfall, floods and disaster declarations, California finally has a dry forecast. But, the team asks, has all this water helped ease the State’s worst-in-a-century drought? And will we see more of these dramatic swings in weather as climate change worsens? Science has shown what most people who take antidepressants already know - that they blunt both bad and good emotions. The team explores the implications of this new study. You may be noticing a few bonus episodes popping up in your feed lately. The team shares a teaser of the latest ones, including a discussion about ‘tipping points’ with climate scientist Tim Lenton, and a chat with fungal pathogen expert Mat Fisher about the new fungal horror TV show The Last of Us. On the pod are Rowan Hooper, Penny Sarchet, James Dinneen, Michael Le Page and Leah Crane. To read about these subjects and much more, you can subscribe to New Scientist magazine at newscientist.com.

S1 Ep 162#162 How to trigger positive tipping points to tackle climate change
On this special episode of the show, host Rowan Hooper and environment reporter Madeleine Cuff chat with climate scientist Tim Lenton of the University of Exeter. Tim has just contributed to a research paper that suggested governments could trigger a mass shift to plant-based diets, simply by serving more vegan burgers in schools and hospitals. We discuss with Tim the power of leveraging so-called positive tipping points to bring about large-scale change. Topics in a wide-ranging and fascinating discussion include: green hydrogen, better fuel for ships, James Lovelock and negative tipping points. These are processes such as the drying of the Amazon rainforest or the melting of the Western Antarctic ice shelf, that, if triggered, would become irreversible and self-perpetuating and that would certainly speed up climate change. One such tipping point that Tim highlights is the Atlantic ocean conveyor belt, and in particular, the deep convection in the Labrador Sea. If the tipping point for this is reached, and models suggest it could happen at the warming we are now seeing, then Europe would shift to a far more seasonal climate, with extremes in both winter and summer.

S1 Ep 161#161 What they don’t tell you about the climate crisis with Assaad Razzouk
In this bonus episode of the podcast, hear Rowan Hooper’s extended interview with Assaad Razzouk, author of Saving the Planet Without the Bullshit: What they don’t tell you about the climate crisis. For a refreshing take on the climate crisis, find out why Assaad believes we need to feel less guilty about our personal actions when it comes to tackling climate change. In this episode he argues things like going vegan and flying less are just distractions, and explains where he believes the real battle lies.

S1 Ep 160#160 Rejuvenation treatments; world to breach 1.5 degrees of global heating
A cure for ageing, without the price-tag? It might sound too good to be true, but the team digs into new evidence that shows low-frequency ultrasound may rejuvenate cells in our body which are thought to cause age-related diseases. Our galaxy, the Milky Way, is missing half of its matter - and the team asks where it’s all gone. They also discuss NASA’s ShadowCam which has taken pictures of Shackleton Crater on the south pole of the Moon, a region of particular interest if humans are to settle on the Lunar surface. Despite dramatic heat waves over the past few years, the Earth has actually been in a cooling period, known as La Niña, for the last three years. So with an El Niño on the way - a period of warming - the team finds out about the coming climate impacts, and how we might breach 1.5 degrees of global heating. Oyster mushrooms eat nematodes - who knew? And as the team finds out, they even do it in a pretty gruesome way, using a sort of nerve gas. The question is, can they still be considered vegan? For a unique take on the climate crisis and the personal responsibility we feel in tackling it, Rowan chats to Assaad Razzouk, author of Saving the Planet Without the Bullshit: What They Don't Tell You About the Climate Crisis. He explains why we shouldn’t worry about going vegan or cutting down on flying, and reveals the real things we should be angry about when it comes to climate change.

S1 Ep 158#158 Exxon’s 1970s predictions for climate change were super accurate
Scientists working for oil giant Exxon between 1977 and 2003 accurately predicted the pace and scale of climate change and warned of the harm of burning fossil fuels, while firm’s executives played down the risk. Now Exxon’s quantitative climate projections have been assessed for the first time. On this special episode of the podcast, host Rowan Hooper discusses the Exxon science with New Scientist environment reporter Madeleine Cuff, and climate scientist Peter Stott. Peter is the author of Hot Air, The Inside Story of the Battle Against Climate Change Denial and is a specialist in climate attribution at the UK Met Office’s Hadley Centre. There is also a contribution from climate scientist Michael Mann. The panel discuss ExxonMobil’s response to the new study, and talk about what we can take from it in terms of not being beguiled by vested interests when pushing for a fast transition to a world free from fossil fuels. The team also reacts to the news that the head of one of the world's biggest oil companies will be president of the COP28 climate summit later this year.

S1 Ep 157#157 Computer lawyer takes first court case; brains speed up with age
Will artificial intelligence replace lawyers in the future? The team learns about a new, chat-bot style bit of tech that fights your legal battles for you, and is about to be tested in a real court room. But is it ethical, or even legal? Gibbons love to sing, but what we’ve just learnt is male and female gibbons also enjoy belting out synchronised musical duets. The team plays some of these delightful sounds, and finds out what this tells us about the evolution of rhythmic capabilities in humans. There’s good news for those of us who are getting on a bit. The team finds out about the very welcome news that some parts of our brains actually speed up when we age. Wind turbines today are already pretty massive - some as high as 250 metres tall. But a new type of turbine has been dreamt up that would rival the tallest skyscrapers. The team discusses the type of engineering that will go into this mega wind turbine, if its inventor can find the $1 billion needed to fund its creation. Stories passed down through aboriginal cultures may provide a roadmap on how to survive the current climate crisis. The writer and theatre-maker David Finnigan speaks to Cassie Lynch, a descendant of the Noongar people of Australia, who’s been studying their storytelling tradition. She reveals ancient knowledge from thousands of years ago, usually only shared among indigenous people. On the pod are Rowan Hooper, Penny Sarchet, Madeleine Cuff and Matt Sparkes.

S1 Ep 156#156: What you need to know in science and culture for 2023
To see in the New Year, host Rowan Hooper and the team look ahead to their science and cultural highlights for the coming months. We start with 2 big planetary science missions due for launch in 2023. JUICE, which will be visiting Jupiter to study some of its moons, and Psyche, which is making a journey to an asteroid made completely of iron. With covid still causing a huge burden of disease around the world, we find out how treatment of the disease is set to evolve this year, and what we can expect from the development of new vaccines. 2023 also looks to be the year of deep-sea mining, as we search for more minerals to fuel the green-revolution. But will countries regulate the industry in time, before it turns into a new wild west? And the team explains how our understanding of pregnancy and the earliest stages of life is set to change this year thanks to work that will accelerate the creation of synthetic embryos. In cultural news, the team looks ahead to an exciting roster of new books coming out this year, including The Terraformers by Annalee Newitz, In Ascension by Martin MacInnes, Saving Time by Jenny Odell, and Breathe: Tackling the Climate Emergency by Sadiq Khan. In film and TV they discuss Christopher Nolan’s Oppenheimer, Dune Part 2, Ant-Man and The Wasp: Quantumania, and the TV adaptation of Bonnie Garmus’ Lessons In Chemistry. There is particular anticipation for the Netflix adaptation of Cixin Liu’s extraordinary book, The Three-Body Problem.

S1 Ep 155#155: Our five favourite New Scientist long-reads from 2022
A holiday special of the podcast and a free-gift giveaway this week, as we celebrate five of New Scientist’s best front-page features of 2022. As well as discussing the features and why they chose to tackle them, the team chats about the beautiful cover artwork for each story. First up is the news that AI is helping to decode the lost stories of ancient Mesopotamia, revealing the secrets of ancient cuneiform texts - the world’s first known writing. Next are the blips recorded by the Large Hadron Collider which have hinted at a potential new force of nature - a discovery which could change physics forever. The most popular feature story of the year was ‘The Longevity Diet: How knowing what to eat and when can help you stay young’. Real news-you-can-use, this feature highlights a new research-based diet that could increase your life expectancy by up to 20 years. If you’ve ever struggled with insomnia, you’ll want to read our feature on its causes, which shows that the sleep disorder is now a solvable problem. And finally is a story which asks, is there a place for consciousness in our understanding of the universe? The team explains the idea that physics needs to embrace subjective experience in order to fully describe and explain the universe. On the pod are Rowan Hooper, Cat de Lange, Dan Cossins and Alison George. These premium features are usually only available to subscribers, but as a holiday gift they’ll be free to read from the 25th December to the end of the year.

S1 Ep 154#154: News review 2022 - stand-out moments and funniest stories
Recorded live online for New Scientist subscribers, in this holiday special the team takes you through their stand out moments of the year, the funniest stories to hit the headlines, and their hopes for 2023 - and they answer questions from the audience too. For stand-out highlights of 2022, the team discusses Deepmind and its transformative AI AlphaFold which predicted the structures of most known proteins. They celebrate the successes of the James Webb Space Telescope and a recent nuclear fusion experiment that has, for the first time ever, generated more power than it requires to run. They also chat about advances in organ transplants and the amazing discovery of ants which have evolved the ability to treat the wounds of their nest mates. For their funniest picks of the year, they highlight the story of a fish that evolved to stand up on land then thought “nah”, and went back to living in water. Then there’s the news of researchers who wanted to find out if covid-related loss of smell correlated with negative reviews of scented candles on Amazon. And they discuss North America’s invasion by alien earthworms. After audience questions, the team looks to the future. From the scientific discoveries spurred on by the covid pandemic, to developments in quantum computing, new innovative ways of producing food in more environmentally friendly ways, advancements in gene replacement therapies and the future of space travel, they discuss the stories they’re most looking forward to next year. On the panel are Rowan Hooper, Penny Sarchet, Alexandra Thompson, Anna Demming and Sam Wong.

S1 Ep 153#153: Fusion breakthrough; COP15 report; Shakespeare and climate change
There’s been an exciting breakthrough in nuclear fusion. For the first time on Earth, a controlled fusion reaction has generated more power than it requires to run, bringing us closer than ever before to a viable way of producing clean energy for the world. So, what’s the catch? The team finds out. The New Scientist team reports from a worryingly quiet COP15. It’s hoped the biodiversity conference will be an opportunity to set ambitious global goals for nature, to reach the goal of restoring it by 2030. But with a distinct lack of world leaders in attendance, can this vital conference deliver? We now know how to spot alien spacecraft whizzing through space at warp speed…assuming some advanced civilisation has figured out how to stretch the fabric of spacetime of course. The team finds out about this new research which involves LIGO and gravitational waves. Shakespeare lived through an intense period of deforestation and climate change, and he referenced a lot of this in his work. Think back to Titania’s speech in “A Midsummer Night’s Dream” about the changing seasons, and when Gloucester in Henry IV part 2 says “the seasons have changed their manners”. Shakespeare even described the energy transition from wood to coal as a fuel source. Rowan chats with Shakespearean scholar Randall Martin from the University of New Brunswick in Canada, and auditions for the part of Queen of the Fairies. Acclaimed science fiction author Adrian Tchaikovsky discusses his latest book, Children of Memory, the story of a fragile human colony on a far flung outpost – and some corvids, which may or may not be sentient. On the pod are Rowan Hooper, Penny Sarchet, Matt Sparkes, Madeleine Cuff, James Dinneen and Alison Flood.

S1 Ep 152#152 Ancient species of human could control fire; complete brain map of fly
An extinct species of ancient human may have been much more advanced than we first realised. First discovered 10 years ago, Homo neladi had a brain about a third the size of ours and yet it may have done complex things like burying its dead and controlling fire. The team learns about the latest finding from the Rising Star cave near Johannesburg. Mars has long been described as geologically dead, but new evidence shows it may still be volcanically active. The team learns about a new theory which might explain what created the mysterious trenches in the Cerberus Fossae region of the planet. The largest complete map of the connections between neurons inside a brain has been made - but it’s not of a human brain. This whole-brain connectome is that of a Drosophila larva - the larva of a fruit fly. The team finds out about this massive undertaking - a stepping stone to describing the brains of more complex animals. Are penguins self-aware? When we try to answer this question in any animal, we tend to use the controversial mirror method - and that’s exactly what a group of researchers have done. But does it actually work, and can we trust the new findings? The remains of the last known thylacine (Tasmanian tiger) have been found, 80 years after they went missing. Self-described Australian mammal nerd Jack Ashby of Cambridge University tells the team how this curious mystery was solved. As the author of Platypus Matters, Jack also shares a story about Platypuses, and the “cocktail of misery” in the animal’s poisonous sting. On the pod are Rowan Hooper, Penny Sarchet, Leah Crane, Alison George and Michael Marshall.

S1 Ep 151#151 COP15: the meeting to save life on Earth; anti-ageing properties of urine
Following repeated delays, the COP15 biodiversity conference is finally going ahead. On December 7th representatives from most of the countries in the world will meet to reach an agreement on how to address the global biodiversity crisis. There’s already a draft agreement in place, and the team explains the ambitions it lays out. But is this event likely to move the needle? A species of rat which should have gone extinct has somehow managed to keep going - and now we know why. In a story worthy of Margaret Atwood, the team finds out how the Amami spiny rat continues to survive despite losing its Y chromosome, the one which makes males. There’s a genuine space race going on, with multiple companies hoping to become the first private firm to land on the Moon. The Japanese mission ispace has hit a delay, but the team explains how a viable lunar economy is now a serious prospect. Newborn female mice who sniff the urine of other female mice live longer - considerably so in fact. The team finds out what’s going on, and whether the finding applies to humans too… And Rowan chats with Henry Gee, senior editor at the journal Nature, who has won the 2022 Royal Society science book Prize. He describes his book, ‘A Very Short History of Life on Earth: 4.6 billion years in 12 chapters’, as a bedtime story for adults, that tells the greatest story ever - the whole saga of life on Earth.

S1 Ep 150#150 Megadrought in the US; how to move an elephant
The southwestern US is currently in the midst of a megadrought - the worst in 1200 years. And it has put the Colorado River in crisis, an essential source of water for more than 40 million people. Can it be saved? Chelsea Whyte investigates. The team unveils the fun new names that have been chosen to define incomprehensibly massive and incredibly tiny numbers. These prefixes describe measurements that have more than 27 zeroes, created as part of the International System of Units. Like mac and cheese but hate the faff of making a roux? You’re in luck. Sam Wong shares a science-based one-pot mac hack, that’ll save you time and up the flavour too. Was COP27 in Egypt a success or a flop? Madeleine Cuff describes it as a mixed bag. After returning from the climate summit in Sharm El-Sheik, she reports on the progress that was made, and the vital issues that must be addressed over the next 12 months. Have you ever wondered how to move an elephant? Well, Ugandan wildlife vet Gladys Kalema-Zikusoka has done it, andit’s a struggle. She was given the task early on in her career, working at the Uganda Wildlife Education Centre, and she shares her experience. On the pod are Penny Sarchet, Chelsea Whyte, Alex Wilkins, Madeleine Cuff, Graham Lawton and Sam Wong.

S1 Ep 149#149 COP27 treaty emerges; a method to discover wormholes
Cheering greeted Brazil’s president-elect, Lula da Silva, when he appeared at COP27 this week. Madeleine Cuff brings us a report from the climate conference in Egypt, where Lula has made bold promises to protect the Amazon. She also tells us what we can expect from this year’s draft treaty - and why the text has been causing quite a stir. There’s plenty going on in Space, with NASA’s Artemis mission now finally launching to the Moon. And the news that we may be able to look for wormholes (if they exist). These are different to black holes because they are traversable - handy if you happen to be an interstellar traveller looking for a fast route across the universe. Our ancestors may have begun using sophisticated cooking methods as long as 780,000 years ago. The team explains how fish teeth have been discovered near hearths at an ancient settlement in Israel. And X-ray analysis suggests they may have been cooked in some sort of earthen oven. Rowan visits a colony of leaf-cutter ants, who use an incredible method of farming fungi that evolved between 45 and 65 million years ago. David Labonte at Imperial College London explains how this complex and decentralised society operates. And have you ever wondered why some poos float and others sink? Too much fat in your diet? Fibre maybe? Or is it gas? Well, new research has lifted the toilet lid on this age-old question, and the team shares the results.

S1 Ep 148#148 Climate action from COP27; world population reaches 8 billion
Warnings over the world’s mad dash to create new supplies of fossil fuels, discussions about climate loss and damage, and talk about nature-based solutions. COP27 in Egypt is in full swing. Our reporter Madeleine Cuff brings us the latest, direct from Sharm el Sheikh. This week’s Sci-fi alert is the unusual discovery of a star with a solid surface. The team explains how on this magnetar (the dense corpse of an exploded star), gravity would be immense and time would behave really weirdly - that’s if you’d be able to land on the thing. They also discuss how the IceCube Neutrino Observatory in Antarctica has been able to plot the course of cosmic neutrinos back to their home galaxy. The 15th of November has been chosen by the UN to mark the point that the number of people on the planet passes 8 billion. Despite this, the team explains how the world’s population isn’t accelerating, and is expected to peak sometime this century - sharing surprising statistics from Japan and China. Birds that migrate long distances are more likely to break up with their partners. Usually bird species are pretty much monogamous, so the team finds out why travelling species find it harder to stay together. “May this tusk root out the lice of the hair and the beard.” The team shares news of the discovery of the oldest readable sentence written using the first alphabet.

S1 Ep 147#147 The oldest yew trees in Europe – and how to save them
In a special episode of the podcast, host Rowan Hooper visits Newlands Corner in the North Downs in southern England, the site of one of the oldest and most significant populations of wild yews growing anywhere in the world. Yew trees are familiar from churchyards and are also revered by pagans and shamans. They can live for many hundreds of years. The grove at Newlands Corner is an exceptional ecosystem, with yews over 1000 years old, but they are declining, losing their needles and slowly dying. Rowan meets arboreal scientist Geoff Monck of Treecosystems, who specialises in surveying and restoring arboreal ecosystems. The cause of the decline in ancient yews has many factors, but the impact of nitrates in rainwater and in run-off from crop fields is perhaps the most important. Rowan hears how nitrates are changing the way the wood wide web operates, and how we might be able to fix it. New Scientist podcasts are freely available. Subscribe at newscientist.com/podcasts.

S1 Ep 146#146 Accelerated end to fossil fuel; double discovery on Mars
Spurred on by the war in Ukraine, we’re seeing a worldwide shift to green energy, with the global demand of fossil fuels now expected to peak in 15 years - a dose of optimism ahead of COP27. The climate conference kicks off in Egypt on November 6, and the team brings a round-up of what we can expect. Maddie and Rowan also discuss their recent visit to the London Literature Festival, where they saw Greta Thunberg speak. ‘Marsquakes’ studied by NASA’s InSight lander suggest Mars may still be volcanically active - and it may have a subsurface water table similar to the one on Earth. The team says this is exciting news for the prospect of life existing on the Red Planet. “A victory not only for the region, but for humanity and life itself.” Brazil’s President Jair Bolsonaro has been unseated by Luiz Inácio Lula da Silva. The team explains how Bolsonaro has presided over climate catastrophe, and why this news has sparked celebration - and relief - from environmentalists. Genetically modified mosquitoes have been released in a city in Brazil. The team explains how UK-based biotechnology firm Oxitec have done this in an effort to find ways to eliminate mosquitoes. The insects transmit deadly diseases like malaria, which kills more than 600,000 people a year. And we bring you a controversial ‘Lifeform of the Week’ - everyone’s most hated amphibian, the cane toad. Quite disturbingly, the team explains how new x-ray video footage shows that cane toads lick their own hearts when they swallow prey. Gross. On the pod are Rowan Hooper, Madeleine Cuff, Sam Wong, Chris Simms and Alexandra Thompson. To read about these subjects and much more, you can subscribe to New Scientist magazine at newscientist.com.

S1 Ep 145#145 COP27 climate summit preview; unexpected animal sounds
It’s already been a year since COP26, with its successor COP27 gearing up to begin on 6 November. 12 months on from some big pledges, the team finds out how much action has actually been taken, and whether this next climate conference is set to move the needle further. Quacks, barks and farts; listen out for some intriguing and unexpected animal sounds. The team shares the newly discovered vocalisations of some animals, like turtles and lungfish, that we previously thought were silent. Turmeric has become an increasingly popular supplement, particularly in the US. But reports are coming in that the spice is causing liver injuries and turning people’s skin yellow. The team finds out what’s going on. A quantum watch is a completely new way to measure time. Using quantum interference, this new technique can accurately measure tiny nanoseconds of time. Although its applications are quite niche, the team explains how this technology could be very useful. As a Halloween treat, our Life Form of the Week is the pumpkin and other squashes. The team dives into the surprising origins of these strange, hard-skinned fruits, and how they came to spread worldwide. On the pod are Penny Sarchet, Chelsea Whyte, Michael Le Page, Leah Crane, Sam Wong, Alice Klein and Rowan Hooper.

S1 Ep 144#144 Geoengineering plan to slow the melt of arctic ice
An extended bonus episode of the podcast, where we learn more about proposals to slow the rate of ice loss in Greenland - and if it works, in Antarctica - using a local form of geoengineering. Host Rowan Hooper speaks to glaciologist John Moore and environmental social scientist Ilona Mettiäinen, both from the University of Lapland in Finland. They discuss the proposal, which involves building a giant, submerged curtain to stop warm sea water getting underneath the ice sheet. They explore the funding and effort needed to pull off a project as big as this. And they talk about local people’s feelings about preserving the ice, as for any intervention it will be vital to have endorsement from Greenlanders.

S1 Ep 143#143 Bird flu sweeps UK; secrets of the Neanderthal family
Wild bird populations have been devastated by an avian flu variant that’s sweeping the UK - and more than 3.5 million captive birds have been culled. It’s expected to be the worst winter on record for avian flu - and the team finds out why. Female robins sing just as much, and just as beautifully, as their male counterparts. It might sound like a no-brainer, but we’ve only just found this out, which the team explains is due to a male bias in ornithology. They share songs from both a male and female robin, and discuss how brutally aggressive these birds can be. New Neanderthal genomes have been sequenced, giving us a glimpse into the lives - and inbreeding habits - of a family that lived in a cave in the Altai mountains. Livers transplanted from older donors can keep working for over 100 years - outliving those given by younger donors. There are some clues that might explain how this is possible, and the team says it could be a game-changer for the future of transplant surgery. If all the ice in Greenland melted, it would raise the sea level by 7.2 metres. Although some melting is already locked in due to climate change, it might be possible to physically slow the rate of ice loss. Following a meeting of the Arctic Circle Assembly in Iceland, a team of scientists is investigating a way of slowing the ice melt by stopping warm sea water getting underneath the ice sheet. Rowan speaks to glaciologist John Moore and environmental social scientist Ilona Mettiäinen, both from the University of Lapland in Finland.

S1 Ep 142#142: We need to talk about mental health and climate change
In 2022, for the first time, the Intergovernmental Panel on Climate Change included mental health as part of its assessment of the impacts of climate change. Conditions such as anxiety, stress and post traumatic stress disorder are all predicted to increase as temperatures rise and people experience extreme weather events. To mark World Mental Health Day (Monday 10th October), Rowan spoke to ‘Losing Eden’ author Lucy Jones, and energy and climate scientist Gesche Huebner, to find out how the climate and nature crises are impacting our mental health - and what to do about it. This episode is an extended version of the edited interview on last week’s podcast - we hope you enjoy it.

S1 Ep 141#141 Energy threat to international security; a new form of multiplication
The climate crisis is as great a threat to energy security as Russia’s war on Ukraine, warns the World Meteorological Organization. The team finds out what sort of threats we’re talking about, and discusses potential solutions. Imagine looking up at the skyline, ready to take in a beautiful sunset, and there it is - a massive, Moon-sized advert, stretched out across the skyline. The team explains how it might be possible (and practical) to do it soon. The erect-crested penguin is the least studied penguin in the world - largely because it lives on remote islands off the coast of New Zealand. But Rowan and Alice find out more - as well as discovering about the surprising sex lives of penguins. DeepMind’s newest artificial intelligence has discovered a new way to multiply numbers - the first improvement in over 50 years. It’s an algorithm for something called matrix multiplication, and the team finds out how it could speed up computers by as much as 20 per cent. To mark World Mental Health Day (Monday 10th October), Rowan speaks to ‘Losing Eden’ author Lucy Jones, and energy and climate scientist Gesche Huebner, to find out how the climate and nature crises are impacting our mental health - and what to do about it.

S1 Ep 139#139 Gas leak impact on climate change; a new way to explain life
Exploding gas pipelines have signalled a new environmental disaster. Nord Stream 1 and 2 have both sprung leaks, with many assuming sabotage. With huge amounts of methane released into the atmosphere, the team examines the climate impact of the damage - and puts the leak into context. During the height of the covid-19 pandemic, male birth rates dipped, temporarily altering the normal gender ratio of babies. The team finds out why and how this happened. Feeling itchy? Researchers have been looking at mice to figure out why itching is contagious - and the mere mention of the word has our panel scratching like mad! The molar teeth of primates, including humans, can clue us into how quickly their fetuses grow during pregnancy. The team finds out about a new mathematical model which is helping us to better understand the evolution of our species. Ahead of New Scientist Live this weekend (8th - 9th October), Rowan chats with star speaker Nick Lane of University College London. Nick explains how much of the chemistry of life seems to happen spontaneously - and how this understanding allows us to unpack the deepest mysteries of biology, from how life got going to what makes us conscious.

S1 Ep 138#138 UK government’s attack on nature; when you can’t stop laughing
The UK government is being accused of mounting an attack against nature. Environmental charities claim a raft of newly announced or rumoured plans are likely to cause harm to the environment for the sake of economic growth. The team unpacks these concerning decisions. When you catch yourself in a fit of giggles, have you ever wondered why it’s so hard to get your words out? Well, the team discusses new research into the phenomenon, which shows the battle that goes on in our brains during a bout of uncontrollable laughter. The team brings you a cosmic interlude, starting with a discussion about NASA’s planet-saving DART mission, which successfully smashed into an asteroid. They then dig into the exciting news that astronomers have found remnants of the explosion of one of the first stars in the universe. Deforestation in the second biggest tropical rainforest in the Americas, the Maya forest, is being reversed. The team celebrates the success of a community-led conservation programme in Guatemala. Coronavirus vaccines may stave off the effects of long-covid. As covid infections pick up again in the northern hemisphere, the team looks at new research from the Office of National Statistics.

S1 Ep 137#137 How to turn the shipping industry green; Enceladus passes habitability test
‘Get it Done’ is the theme for this year’s Climate Week in New York, with hundreds of events taking place across the city. Reporter James Dinneen is there, and brings us news about how to reduce the massive impact of the shipping industry on greenhouse gas emissions. NASA’s DART mission is the first real-world planetary defence mission. And on Monday a 500-kilogram satellite will smash into a small asteroid called Dimorphous to try and change its orbit. The team explains what the mission hopes to achieve. Ants are everywhere. In fact, it’s estimated that Earth is home to 20 quadrillion of the things. Think of all the legs! In light of this news, the team discusses their favourite ants (yes they have favourites) - including the weaver ant which Rowan has been reading about in his favourite bedtime book, The Guests of Ants. Phosphorus has been discovered on Saturn’s moon Enceladus, meaning it now has all six of the essential elements for life. The team explains how the element was found in icy rock grains collected by the Cassini spacecraft. Covid may be triggering early puberty in some girls. While the condition was known about pre-pandemic, the surprising finding shows that since covid it’s happening in higher numbers and even sooner, in girls younger than seven. The team discusses whether it’s the stress of the pandemic or the disease itself that’s causing these effects.

S1 Ep 136#136 A step towards building artificial life; solar-powered slugs
Ribosomes are tiny protein-making factories found inside cells, and a crucial component of life. And now a team of scientists has figured out how to make them self-replicate outside of cells. Without getting all Mary Shelley, the team says this is a step towards creating artificial life. On a trip to the Isles of Scilly, Rowan found a spectacular lifeform of the week. On the shores of Porthcressa beach on St Mary’s island, he found a solar-powered sea slug, with the help of Scott and Samaya of Scilly Rockpool Safaris. America’s West Coast is still being ravaged by wildfires, and not only are they set to become more frequent as the climate warms, but they’re going to become even more intense. Chelsea, who can see the orange skies of the fires from her home, discusses the rising risk of so-called ‘extreme wildfires’. Rowan makes the point that new research shows that transitioning from fossil fuels to clean energy could lead to savings of $5 to $15 trillion dollars. Centenarians - people who live to be older than 100 - who have all the markers of Alzheimer’s, don’t appear to be affected by the disease. The team finds out about an intriguing new finding that upends our understanding of amyloid plaques, the proteins we think are closely associated with dementia. Climate change artist and Australian playwright David Finnigan discusses his latest play ‘You’re Safe Til 2024: Deep History’, which he performed at this year’s Edinburgh fringe festival and which is coming to London. It looks at the 75,000 year history of our impact on the environment from the lens of the 2019 Australian bushfires. On the pod are Rowan Hooper, Chelsea Whyte, Abby Beall and Carissa Wong.

S1 Ep 135#135 The Amazon passes a tipping point; a place to live only 100 light years away
The Amazon rainforest may have passed the tipping point that will flip it into savannah. A new report suggests that large portions of the rainforest have been either degraded or destroyed, which could have disastrous consequences. The team hears from the Science Panel for the Amazon, who say we must step in now to support regeneration efforts. If you’re looking for a drummer for your new band, you might want to hire a chimp. The team hears recordings of chimps drumming on the buttresses of tree roots in Uganda’s Budongo Forest, and explains why they do it. Meta wants to read your mind - eventually. The panel discusses a new AI developed by Facebook’s parent company, that can detect certain words by reading brainwaves. New Scientist’s chief gourmand, Sam Wong, gets the team to taste-test a west-African fruit called the miracle berry, and explains how it could help curb our sugar addiction. He also discusses the fermenting process and its possible health benefits, while sharing a little of his delicious fermented hot chilli sauce. 100 light years away, we’ve spotted new exoplanets that may be good places to search for life. They exist in the habitable zone, near a red dwarf star with the delicious name SPECULOOS-2. But the planets are different to Earth, and the team discuss the chances they will support life (as we know it).

S1 Ep 134#134 Artemis moon mission; decoding the dreams of mice
The launch of NASA’s Artemis moon rocket didn’t go to plan this week. The team looks at the problems that stopped this long-awaited launch. And with the launch rescheduled for Saturday, they find out what the mission hopes to achieve. Deep below the surface of the Earth live nearly half of all microbes on the planet. While studying life in the deep biosphere is tough, the team shares an exciting development. Researchers have managed to find and analyse a type of heat-loving bacteria, called thermophiles, that eat petroleum. As the global climate warms, some areas of the world will become unlivable, forcing people to leave their homes and countries. In her new book ‘Nomad Century’ Gaia Vince explains how the tragedy of mass climate migration can also be seen as an opportunity. She explains her thinking, and the action we urgently need to take to survive in a warming world. Why do our eyes dart around when we dream? It’s long been a mystery, but the team learns how mice are helping us understand what really happens during REM sleep. Mucus is incredibly important for mammals, keeping everything running like a well oiled machine. Now surprising new research looking at species as diverse as rhinos, pangolins and ferrets has revealed its unusual evolutionary history, and the team discusses these findings.

S1 Ep 133#133 A treatment for food allergies; predicting earthquakes
There may be a way of treating, or even preventing, food allergies. A promising new trial has used a fat molecule called butyrate to treat peanut allergies in mice. The problem is, butyrate smells like dog poo, so the team finds out how researchers are getting around that issue. We’ve long thought earthquakes happen randomly, but that may not be the case. A new modelling technique using old records and machine learning shows we may be able to predict earthquakes, which could save millions of lives. The team finds out how this method works, and why it’s not fool-proof yet. Philosopher Will MacAskill tells us about the concept of long-termism, which is about prioritising the long-term future of both people and planet. He explores some of the messages in his new book What We Owe the Future. Yields of soya have been boosted by a fifth, without adding any fertiliser at all. Genetic modification has been used to improve photosynthesis in the crop. The team says this is great news for farmers, wildlife, consumers and the climate. By studying Antarctica’s ice shelves, researchers have predicted that a special kind of ice falls upwards in the ocean on one of Jupiter’s moons. The team explains how this could be promising for hopes that Europa harbours life. On the pod are Penny Sarchet, Chelsea Whyte, Michael Le Page, Leah Crane, Alex Wilkins and Carissa Wong.

S1 Ep 132#132 Impact of drought; monkeys using sex toys
Droughts in many parts of Europe are the worst in 500 years. Even as temperatures begin to cool and some rain begins to fall, it may be a long time till we’re out of the woods. The team explores the impact the droughts are having on things like food production, energy and transport, and wildlife. Monkeys use sex toys too - who knew? Long-tailed macaques in a Balinese sanctuary have figured out how to use stone tools to masturbate. The team finds out what’s going on… Radiation exposure is one of the biggest issues we’re going to face if we want to get people to Mars. The team looks at new research that shows just how extreme the dangers are, and they look at the possible consequences. Quantum computer experts want to build a brain-like computer out of giant atoms. The team finds out how physicists plan to use laser beams to build an artificial neural network, and hear what Data from Star Trek: The Next Generation has to do with it. This week Rowan is delighted to chat with BAFTA-winning sound artist Chris Watson. Chris shares gorgeous soundscapes recorded in three threatened ecosystems, the Vatnajökull Glacier in Iceland, the Namib desert in Africa, and the Long Shore Drift off the coast of East Anglia. The sounds are being used in a collaboration with the Manchester Collective, to bring to life Michael Gordon’s cult work ‘Weather’. Chris was a founder member of legendary Sheffield band Caberet Voltaire, who happen to be the first band Rowan ever saw live. BONUS: Stay till the end to hear the sound of saiga antelopes on the steppe grasslands of Kazakhstan, where they have rebounded after being on the brink of extinction.

S1 Ep 131#131 Why thinking hard tires you out; game-changing US climate bill
The US is about to pass an historic piece of climate legislation. The Inflation Reduction Act allocates $370 billion to climate mitigation, and the team explores how that money will be spent - plus why some people think the bill holds us hostage to fossil fuel. Do you ever get embarrassed talking to Siri when you’re out in public? Well, the team learns about an experimental new piece of tech called EarCommand, which may make communicating with your virtual assistant less awkward. Thinking hard is tiring - and a new study may have figured out why. As the team explains, it’s surprisingly more complex than just running out of energy. Say it with us - pobblebonk! The acid-defying scarlet-sided pobblebonk frog is our lifeform of the week. Find out how this splendidly named creature survives in some incredibly hostile environments. Antonio Padilla, cosmologist and author of Fantastic Numbers and Where to Find Them, explains how weird and wonderful numbers - like Graham’s Number - can give us a glimpse into the biggest secrets of the universe.

S1 Ep 130#130 How to reverse death; Neil Gaiman on Sandman; AlphaFold and biology’s revolution; life in the multiverse with Laura Mersini-Houghton
A new type of artificial blood has been created which, in the future, could bring people back from the dead - or what we think of now as dead, at least. This special fluid has been shown to preserve the organs of dead pigs, long after what was previously thought possible - which the team says could be a game-changer for organ transplants. Rowan talks to legendary writer Neil Gaiman about the new Netflix series, out this week, based on his smash-hit Sandman comics. They also discuss the function of dreams, and the inspiration Neil draws from them. This week we also chew over the recent massive news that DeepMind’s artificial intelligence AlphaFold has predicted the structure of nearly all proteins known to science. It is, says the team, as monumental as the discovery of the structure of DNA. The team explains how transformative this could be in areas like disease prevention. Leaving Earth, we talk with cosmologist Laura Mersini-Houghton about her theory that we live in just one of a vast multiverse of universes, a subject she tackles in her new book ‘Before the Big Bang’. And there’s yet more amazing findings to discuss from the James Webb Space Telescope, including the possible discovery of a galaxy formed not long after the universe itself.

S1 Ep 129#129 BlueDot special: Mysteries of the universe; stories of hope and joy; growing tiny human brains; solving global problems
Welcome to a special edition of the show recorded live at the bluedot music festival. On the panel are New Scientist journalists Rowan Hooper and Abby Beall, along with Emmy-nominated composer Hannah Peel and geoscientist and broadcaster Chris Jackson. With the awesome Lovell radio telescope dominating the sky above the festival, this episode begins with astronomy news, and in particular stories from the James Webb Space Telescope - including its mission to look at the atmosphere of rocky planets in the search for extraterrestrial life. There’s also a nod to the late great James Lovelock, who has died at the age of 103. The panel brings their stories of joy and hope. Abby brings news of the saving of a research centre for intelligent birds. Chris marvels at an impressive global geological event which highlights the power of collaboration. Hannah dreams up a story about “nanoskin” which happens to be very similar to a real story we reported. And Rowan comes with the news that chimps have been found to treat each other using medicinal insects. The panel discusses the ethics and possibilities of brain organoid research. These are tiny human brains grown in a lab, which have recently been shown to give off brain waves equivalent to those seen in fetuses. The whole team is gifted with an imaginary $100 million, and asked how they’d use it to save the world. Rowan wants to refreeze the Arctic. Then there’s a vibrant Q&A session with the audience. And for the boy who asked about brain organoids playing Pong, here’s the story.

S1 Ep 128#128 Extreme heatwaves; China’s space station launch; covid’s effects in pregnancy; a black hole symphony
Following scolding 40 degree record temperatures, it’s clear the UK is not set up to deal with such heat. But as extreme weather events become more common, how can we prepare for a hotter future? The team finds out, and looks to the US and Europe where hot temperatures are also wreaking havoc. China’s space plans are rocketing forward, as the country prepares to launch the second part of its space station into orbit on 24 July. With the third and final module due to launch in October, the team finds out what China is planning to do aboard the new station. What does a black hole sound like? Although we can’t answer that literally, a process called data sonification offers up a solution - by converting astronomical data into sounds and music. The team shares two beautiful pieces composed for an immersive new production called ‘Black Hole Symphony’. Covid-19 has been found to increase the risk of premature birth if caught during the final trimester of pregnancy. The team explores the findings and what they mean for pregnant people. Plant communities could be fundamentally changed by declining pollinator populations, suggests a surprising experiment. The team examines the risk this poses to biodiversity. On the pod are Penny Sarchet, Emily Bates, Michael Le Page, Jason Murugesu, and Alex Wilkins. To read about these stories and much more, subscribe at newscientist.com/podcasts.

S1 Ep 127#127: Pig hearts transplanted into dead people; James Webb Space Telescope gives best-ever view of the universe; boosting wheat genetics to feed the world
After the first pig-human transplant patient died just 2 months after receiving his new heart, researchers are now testing modified pig hearts by transplanting them into recently deceased people on life support. The team discusses a new experiment which has shown very promising results. NASA has revealed stunning images of deep-space captured by the James Webb Space Telescope - and there’s so much more to come. The team explains how the telescope is like a time machine, helping us to peer back into the early history of the universe. Much of the information our eyes take in is discarded by the brain. The team discusses a new technique called ‘ghost imaging’ which is using AI to reconstruct those lost images by interacting directly with our brain. Wheat hasn’t yet reached its genetic potential. The team finds out how genetically tweaking this vital crop could improve yields globally, and help it to withstand the impacts of climate change. Covid-19 is impacting fertility through its impacts on sperm - yet another thing we’re finding out about the disease. The team finds out what’s going on, and how long-lasting these effects are. On the pod are Rowan Hooper, Penny Sarchet, Jacob Aron, Karmela Padavic-Callaghan, Grace Wade and Carissa Wong. To read about these stories and much more, subscribe at newscientist.com/podcasts.

S1 Ep 126#126: Are we stuck in a time loop? Legal action against climate change; covid fifth wave; time loop are we stuck?
Ten years since the discovery of the fabled Higgs boson, can the Large Hadron Collider ever make us that excited again? Physicists are now kind of bored by the Higgs - the hype has well and truly died down. So as the LHC kicks off its third period of operation, the team asks whether there will be anything new to get them fired up again. How do large hawks land without crashing? That’s what a team of researchers has been trying to find out. The team explains how their findings could help with future innovations in drone technology. ClientEarth is an environmental legal organisation, or “lawyers for the planet”, with the aim of holding companies and governments to account over net zero plans. The organisation has recently brought cases against the Dutch airline KLM and French oil giant Total Energies for alleged greenwashing. Rowan speaks with Chief Impact Officer and “head of greenwashing” Maria Krystyna Duval. A strange kind of time paradox called causal loops is being researched. As well as explaining what a causal loop is, the team explains how a large set of theoretical universes were studied to see whether this time-travel paradox could actually work. The UK is being hit by a fifth wave of coronavirus cases, with many people becoming reinfected multiple times. The team examines the possible risks of reinfection, and asks if there’s an end in sight. On the pod are Rowan Hooper, Penny Sarchet, Jacob Aron, Karmela Padavic-Callaghan and Corryn Wetzel.

S1 Ep 125#125: Poo transplants cure IBS; climate change shrinks the human niche; CRISPR babies; monkeypox latest
The world’s first CRISPR babies are now toddlers. Now, nearly four years since the super-controversial experiment was announced, scientists in China want to set up a healthcare institute specifically to look after the three children. The team examines the ethics of it all. Humans thrive at particular temperatures, and that’s why we live where we live. But these areas of optimal climate are shrinking because of climate change. As we’re on course to hit 2.7 degrees of warming by the end of the century, the team finds out what will happen to future populations. And with the UN Ocean Conference taking place, we hear a clip of Sounds of the Ocean by composer Joshua Sam Miller, a piece where the lead singer is a whale! Poo transplants are being used to cure irritable bowel syndrome. The team discusses the success of a new trial which used the poop of a single, healthy athletic man - a super-pooer, basically - to introduce a healthy mix of gut microbes into those with the condition. Rogue planets, roaming through space without a star of their own, may still be able to host life. Even without the heat of their own Sun, the team explains how there is still a way that life could thrive. We’re in the middle of the biggest outbreak of monkeypox ever. With cases spreading fast, the team asks why the disease isn’t killing anyone yet, and they find out how big this outbreak could become. On the pod are Rowan Hooper, Penny Sarchet, Michael Le Page, Alice Klein, Leah Crane and James Dinneen. To read about these stories and much more, subscribe at newscientist.com/podcasts.

S1 Ep 124#124: Lopsided universe; solar activity affects heart health; hero rats trained for rescue missions
If you like things orderly, we have bad news for you - our universe is lopsided. Based on everything we know about gravity and the early universe, we’d expect galaxies to be distributed symmetrically - but they’re not. Something spooky’s going on, and the team searches for answers. The activity of the Sun may be affecting our heart health. Sometimes the weather on the Sun gets a little chaotic, and the team discusses new research that suggests these solar storms are messing with our heart rhythms, raising the risk of heart attacks. African pouched rats are being trained as heroes. Donning special little backpacks, they will use their keen sense of smell to go on search and rescue missions. The team explains why they’ve been chosen for the task. Last September El Salvador became the first country to make cryptocurrency legal tender. But with the value of Bitcoin and other cryptocurrencies plummeting, the team examines what the future holds. Covid-19 is proving resilient, and as new variants of omicron emerge, infection rates still remain high. As omicron is milder than its predecessors, the team asks whether we should still be worried about the disease, and they find out how it may continue to evolve. On the pod are Rowan Hooper, Penny Sarchet, Michael Le Page, Corryn Wetzel, Leah Crane, Jacob Aron and Alice Klein. To read about these stories and much more, subscribe at newscientist.com/podcasts.

S1 Ep 123#123: ‘Sentient’ claim for Google AI; spacecraft spots starquakes; the rise of the mammals; hot brains
How will we know when we’ve made a truly sentient artificial intelligence? Well, one Google engineer believes we’re already there. The team discusses the story of Google’s very clever AI called LaMDA, and ask another chatbot, GPT3, what it would think if LaMDA was destroyed. Did you know stars have ‘earthquakes’ too? These starquakes have been spotted by the Gaia space observatory, which aims to build a 3D map of all the stars in our galaxy. It’s been collecting a phenomenal amount of data, and the team explores its findings. Net Zero pledges are becoming more popular - which is great - but a lot of them aren’t being acted on. According to a new consortium Net Zero Tracker, a worrying number of these pledges aren’t credible. The team finds out how the group aims to hold companies to account. Our brains are hotter than we realised - 2.5 degrees celsius hotter in fact. The team asks why we’re only just finding this out in 2022, and how the discovery may improve care for people undergoing brain surgery. Steve Brusatte is best known as a dinosaur palaeontologist, but he has turned his attention now to our own class, the mammals. Rowan chats with him, and amongst other things finds out how enslaved Africans in South Carolina were instrumental in the development of palaeontology. On the pod are Rowan Hooper, Penny Sarchet, Clare Wilson,Matt Sparkes and James Dinneen. To read about these stories and much more, subscribe at newscientist.com/podcasts.

S1 Ep 122#122: The science of Top Gun; the 1.5°C climate goal is out of reach; return to the moon; hepatitis mystery
While it may be technically possible to keep global heating to 1.5°C it’s really not very likely - at all. So why are we clinging to it? The team asks, when do we admit that 1.5°C is dead, and what will it mean when we do? NASA is about to launch its CAPSTONE spacecraft into lunar orbit, paving the way for its lunar space station. As a precursor to the Artemis mission to put people back on the moon, CAPSTONE is basically a test run, and the team explains its goals. Rowan’s been to see Top Gun: Maverick, and he’s found a way of making it about science - or technology, at least. In the film we see many new applications of technology and artificial intelligence in warfare, so we chat with AI and drone expert Arthur Holland Michel to discuss the future of combat and what Top Gun 3 might look like in another thirty years. The team brings you an incredibly exotic life form of the week… chickens! It turns out that chickens were domesticated a lot more recently than we thought. Hear some of the humorous archaeological blunders that have led to this confusion. In recent months doctors around the world have been reporting mysterious cases of children suddenly developing liver failure. While we don’t know what’s happening, the team explores some possible explanations. On the pod are Rowan Hooper, Penny Sarchet, Michael Le Page and Adam Vaughan.

S1 Ep 121#121: Creation of artificial life; gene therapy saves children’s lives; new understanding of chronic pain
Synthetic cell membranes have been fused with protein machinery from living cells to create an artificial membrane. Could this be a precursor to the creation of artificial life? The team discusses its potential and limitations. Babies with severe genetic conditions are being cured by new gene replacement therapies, allowing them to overcome fatal diseases. There are a number of different treatments which have seen success, and the team finds out how they work. The DNA of two people who were killed by the eruption of Mount Vesuvius in Pompeii has been sequenced. The team finds out how the DNA from 79 AD managed to survive the heat of the volcano, and what the findings tell us about the lives of these two people. Solar sails - a method of harnessing the sun’s light for space travel - are usually quite clumsy, so a NASA-funded team is developing a new more agile type of solar sail. The team finds out how they’re overcoming the problem. Haider Warraich, a physician at Brigham and Women’s Hospital and Harvard Medical School, discusses his new book ‘The Song of Our Scars: The Untold Story of Pain’, which addresses “modern medicine’s failure to understand pain”. On the pod are Rowan Hooper, Penny Sarchet, Chelsea Whyte, Leah Crane, Alice Klein, Anna Demming and Alex Wilkins. To read about these stories and much more, subscribe at newscientist.com/podcasts.
