#91: Earth heading for climate disaster; Kim Stanley Robinson looks to the future; hunt for aliens; Tesla worth $1 trillion
The Earth could be heading for disaster. In the lead up to COP26 the team discusses The Emissions Gap, a new UN report which has found that even if countries around the world stick to their emissions pledges, the planet will still warm by 2.7°C, which would be catastrophic. Legendary sci-fi writer Kim Stanley Robinson makes an appearance, discussing his climate heroes, thoughts on geoengineering and on the future of the planet. The team unveils the news that a signal from space that looked like it was sent by aliens… probably wasn’t aliens. They also explain why sperm quality is declining in American men, prompting predictions that the average sperm count will hit zero by 2045. And they discuss the news that Elon Musk’s Tesla has become only the sixth US company ever to reach a trillion dollar valuation. On the pod are Rowan Hooper, Chelsea Whyte, Alice Klein and Leah Crane. To read about these stories and much more, subscribe at newscientist.com/podcasts.

#90: COP26 climate playlist; the science of Dune; life-saving treatment for children without immune systems; covid sweeps Iran
In rare cases children can be born without an immune system, and sadly their chances are very bad. Fortunately the team brings news of a life-saving implant which has now been approved for use in the US. If you’re thinking of seeing the new film adaptation of Frank Herbert’s epic novel Dune, you’ll want to hear the insights of ecosystem professor Yadvinder Malhi. Herbert was amazingly ahead of his time, anticipating the work of James Lovelock and the Gaia hypothesis, for example. The team hears about the world’s largest artificial intelligence - the Megatron-Turing Natural Language Generation model - and finds out what it is capable of. They also discuss how hard Iran has been hit by the coronavirus pandemic: new data shows nearly every person in the country has had covid, some twice or even three times. And in the build up to COP26, the team is getting in the party spirit, and shares details of a climate-inspired Spotify playlist they’ve put together. You can listen to it here. On the pod are Rowan Hooper, Chelsea Whyte, Alice Klein, Bethan Ackerley and Matt Sparkes. To read about these stories and much more, subscribe at newscientist.com/podcasts. Hosted on Acast.

#88: Should climate activism go to extreme levels?; malaria vaccine; new drugs to treat covid; mission to the asteroid belt
The team opens with the welcome news that after 37 years of development, the world’s first malaria vaccine has been approved. They then hear from Swedish author Andreas Malm, who argues that the climate movement needs to get more militant. He says the likes of Extinction Rebellion have 'peace-washed' historical accounts of protest movements, and, controversially, puts the case for escalating from mass civil disobedience to engage in property destruction. The fight against covid is picking up pace - the team unpacks a flurry of announcements about promising new treatments. They discuss the new UAE space mission launching in 2028 which plans to swing by Venus before heading to the asteroid belt between Mars and Jupiter. They also share a roundup of the physics and chemistry Nobel prize winners, and find out how touch receptors in the skin are involved in social bonding and sexual desire.

#86: The woman who couldn’t smell; solving the climate and biodiversity emergencies; China’s quantum of solace
Imagine going your whole life without being able to smell - and then suddenly you can. The team tells the amazing story of a woman who first gained the ability to smell aged 24 - a case which has scientists baffled. Efforts to tackle the climate and biodiversity crises need to be unified. We hear from Nathalie Pettorelli of the Zoological Society of London, lead author of a new paper calling for a more joined up approach, with an emphasis on nature-based solutions. The team discusses the latest developments in quantum computing, including a city-wide quantum communications network in China that has been running for almost three years - showcasing how a future quantum internet might work.

The team also questions the wisdom of rolling out covid-19 booster jabs. Some countries are already gearing up to deliver dose number three, all while poorer populations struggle to get their hands on a first dose. Potential homes have been identified for Martians of the future - the team talks about the discovery of caves on Mars which could be turned into settlements for human explorers. They also discuss the news of a billionaire-funded lab that’s been set up with the aim of ‘curing’ the ageing process. And you even get to hear the words of a swearing duck which has learnt to say ‘you bloody fool’ - yeah, you read that right. On the pod are Rowan Hooper, Penny Sarchet and Alice Klein.
