#80: Analysis of IPCC climate report; the rise of synthetic milk; discovery of new carnivorous plant Aug 12, 2021

Show notes

A lead author of the latest IPCC climate report, Tamsin Edwards, joins the team for a special episode of the podcast. News headlines have left many concerned, and with more questions than ever, so the team devotes a large chunk of the show to unpacking the findings of the report, and emphasising hope and action over doom and gloom. Linked to the issue of climate change is the agricultural industry’s impact on the environment, but there’s hope there too. The team explains how precision fermentation technology is being used to create guilt-free milk, cheese and ice-cream! And the team finds out about a killer tobacco plant - a newly-described species that kills insects and could provide a natural solution to pest control. On the pod are Rowan Hooper, Penny Sarchet, Graham Lawton and Adam Vaughan. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#79: Google creates a time crystal; microplastics in human placenta; boosting China’s vaccines; our climate future Aug 05, 2021

Show notes

As severe weather events around the world give us a very real taste of the devastating effects of climate change, we’re also getting a better understanding of what the future holds for our planet. The Intergovernmental Panel on Climate Change releases its big report on the physical basis of climate change next week - the team previews what’s to come. They also explain why a number of nations are now mixing and matching their vaccine doses in order to stop the spread of the covid-19 delta variant. For the first time, microplastics have been found in human placentas, and the team examines the possible health implications. They also learn about new technology which is being used to send hidden messages in the calls of whales and dolphins, and they get all Doctor Who when they find out about the existence of real life time crystals. On the pod are Rowan Hooper, Penny Sarchet and Matt Sparkes. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#78: Will covid evolve to evade vaccines?; the oldest animal fossils ever found; predicting climate change’s extreme weather Jul 29, 2021

Show notes

More than a week since England lifted its covid restrictions, infection numbers in the UK are very high. The team examines how the country has set up the perfect circumstances for the evolution of “escape variants” - forms of the virus that may be able to evade our immune systems and vaccines. The team also learns of the discovery of the earliest fossil animals ever found - sponges that are 350 million years older than anything we’ve seen before. They explain how a 14-legged single-cell organism is able to walk without a brain. They also discover what would happen if two superfast stars smashed into each other, and find out why many climate models weren’t able to predict the severity of recent extreme weather. On the pod are Penny Sarchet, Timothy Revell, Leah Crane and Michael Marshall. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#77: Is dropping covid restrictions unethical?; methane hints to life on Mars; Jeff Bezos and Blue Origin’s road to space Jul 22, 2021

Show notes

Freedom day arrived in England this week, as the country dropped most covid restrictions. But as cases continue to rise and many people, children included, remain unvaccinated, the team discuss why hundreds of experts are calling the move an ‘unethical experiment’. High levels of methane have been detected on Mars by the Curiosity rover, which could indicate life on the Red Planet - but the team explains why they aren’t breaking out the champagne just yet. They then discuss the launch of Blue Origin’s New Shepard spacecraft, with Jeff Bezos announcing his plans to build a ‘road to space’. There’s also news about a tomato nervous system, as biologists discover the sophisticated methods the plants use to communicate. And the team touches on the discovery of a new genetic element named after the Borg in Star Trek, which could aid in the fight against climate change. On the pod are Rowan Hooper, Chelsea Whyte, and Cat de Lange. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#76: Harm of race-based medicine; space tourism industry is go; America’s heatwave challenges Jul 15, 2021

Show notes

Race-based medical practises are being challenged more and more, as it becomes increasingly clear they have little basis in science. The team finds out why adjustments for race and ethnicity are still being made in medicine, despite the potential harm and healthcare implications they cause. It’s been a massive week for the future of space tourism - the team shares a clip of a very excited Richard Branson who’s recent journey into microgravity has set the stage for the launch of Virgin Galactic’s first commercial space flights. The team gives an update on the dramatic heatwave ravaging the US, as more record high temperatures are set, continuing to leave destruction in its wake. They also explain what ‘impact gardening’ is and why it might help us find alien life on Jupiter’s moon Europa, and they share important news on the state of the cosmetics industry in Neolithic times. On the pod are Rowan Hooper, Chelsea Whyte, and Layal Liverpool. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#75: Vaccine for kids; legacy of Dolly the sheep; how to repair the climate; China’s quantum advantage Jul 08, 2021

Show notes

In the UK, rules around attendance at schools after a covid outbreak are changing, but the country still hasn’t decided whether or not to vaccinate children. The team finds out what the hold up is, especially given some countries have already taken the leap. It’s been 25 years since the cloning of Dolly the sheep, so the team looks at Dolly’s legacy, exploring the many advancements and discoveries that have come as a result of this marvel of biological science. They then discuss the small matter of how to save the planet as former UK chief scientist David King, founder of the newly formed Climate Crisis Advisory Group, sets out his mission. In the race to create a breakthrough quantum computer, China is in the lead - the team explores a leapfrogging event which has seen the country achieve quantum advantage, creating the fastest computer on Earth. And they discuss NASA’s exciting plans to create a spacecraft powered by solar sails. On the pod are Rowan Hooper, Chelsea Whyte, Matt Sparks and Clare Wilson.

#74: ‘Dragon man’ could be new species of human; Wally Funk goes to space; human and financial cost of heatwave; how covid affects the brain Jul 01, 2021

Show notes

A unique kind of human skull has been discovered in China. The team describes the details of this skull, known as the ‘Dragon Man’, and explains how it might belong to a new species of human. And if that’s not exciting enough, its discovery has the most amazing Indiana Jones style backstory too. In breaking news, Jeff Bezos has announced that legendary aviator Wally Funk, one of the Mercury 13 women who trained as astronauts, will go to space with him on the first crewed Blue Origin mission. The team then discusses the intense heat waves that have been wreaking havoc in the Arctic and across the Pacific northwest. They explore the effects of covid-19 on the brain, as new studies show that a third of people who’ve been infected have suffered some form of cognitive or psychological disorder. They also share some incredible, experimental music from the composer John Luther Adams, whose new album ‘Arctic Dreams’ is inspired by the sounds of the Alaskan wilderness. And they bring bad news from the surface of Venus, as hopes for life on the planet begin to dwindle. On the pod are Rowan Hooper, Tiffany O’Callaghan, Alison George and Chelsea Whyte.

#73: How to treat long covid; evolution of cooperation; Turing’s ACE computer; aliens watching Earth Jun 24, 2021

Show notes

The symptoms of long covid are diverse and numerous, and we’re still getting to grips with a clinical definition. Adam Vaughan visited the UK’s first long covid clinic, and explains how it provides both physical and psychological support to patients. The team then discusses the evolution of cooperation with professor Nichola Raihani, author of ‘The Social Instinct’, who explains why species collaborate, an act which seems to contradict the competitive nature of life in Darwin’s theory of natural selection. Then they get into the unnerving news that aliens might be spying on us from other planets. They mark the birthday of one of the greatest and most influential figures of the twentieth century, Alan Turing, who features on the Bank of England’s new £50 note. And they explain how quantum mechanics is being used to protect our data online. On the pod are Rowan Hooper, Tiffany O’Callaghan, Adam Vaughan, Matt Sparkes, Leah Crane and Chelsea Whyte.

#72: The evil in all of us; delta variant of coronavirus; glacier memory project Jun 17, 2021

Show notes

The delta variant of covid-19 has torn across India, and is making its way around the globe, forcing the extension of lockdown measures in the UK. The team explores its spread, and also digs into findings showing that “elimination countries” - those which enacted swift and extreme lockdown measures - have fared better across the board in the health, wealth and even freedom of their populations. They then discuss the Ice Memory Project, which is archiving and preserving material and data from glaciers - ancient relics that have been trapped in the ice for millennia, sadly thawing due to global warming. There’s a conversation with forensic psychiatrist and psychotherapist Gwen Adshead about the capacity we all have for evil - the subject of her new book ‘The Devil You Know’. On top of that, there’s the news that China has launched the first group of astronauts to its new space station and laid out its plans for an international moon base, and a story about monogamy in seahorses, where it is the males who get pregnant. On the pod are Rowan Hooper, Tiffany O’Callaghan, and Graham Lawton. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#71: Alzheimer’s treatment approved; human brain map breakthrough; time flowing backwards Jun 10, 2021

Show notes

For the first time in 18 years, a new drug for Alzheimer’s disease has been approved by the US Food and Drug Administration. This is big news because rather than just treating the symptoms, the drug targets the amyloid plaques that are thought to cause the disease. But the team explains why there are still many reasons to remain cautious. They also discuss an exciting breakthrough in our understanding of the brain, as Google researchers have, for the first time, mapped all the connections in one cubic millimeter of human brain tissue, containing a whopping 50 thousand brain cells and 130 million connections. Then there’s the little story about how time can appear to violate the second law of thermodynamics, by running backwards instead of forwards. The team also celebrates the revival of an animal frozen in permafrost for 24,000 years, and they travel to the very edges of the galaxy where, for the first time, organic molecules have been detected. On the pod are Rowan Hooper, Tiffany O’Callaghan, Mike Marshall and Anna Demming. To read about these stories and much more, subscribe at newscientist.com/podcasts.
