In the headlines this week eminent tech experts and public figures signed an open letter that read “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”One of the signatories was Geoffrey Hinton, the so-called ‘godfather of AI’. He’s become so concerned about the risks associated with artificial intelligence that he recently decided to quit his job at Google, where he had worked for more than a decade. But are these concerns justified, or is it overblown scaremongering? And should we start prepping for a Terminator-style takeover? To get the answers, presenter Gareth Mitchell is joined by computational linguist Prof Emily M. Bender from the University of Washington along with Dr Stephen Cave, Director at the Leverhulme Centre for the Future of Intelligence (CFI). Next up, we hear from Prof Carl Sayer at UCL, along with Dr Cicely Marshall and Dr Matthew Wilkinson from the University of Cambridge, to dig into the science behind wildflower meadows and whether they can boost biodiversity and even help ease climate change. Finally, have you heard about Balto the sled dog? He was part of a life-saving mission in the 1920s and now he has the chance to be a hero once more. His DNA has been studied by the Zoonomia project, which is using databases of genomes from hundreds of mammals to build a better picture of evolution. This data could then be used help identify those animals that are at the greatest risk of extinction.

This week, we hear from the University of Florida’s Dr David Duffy. He heads up a team of researchers who are studying sea turtles. In order to track the animals and their diseases, the scientists devised a method of collecting fragments of DNA from tanks at the university’s turtle hospital, as well as from sand and water in the local environment. While they found plenty of turtle DNA, they were surprised to uncover large amounts of high-quality human eDNA. Duffy tells us all about the study and his surprising findings, but also highlights the ethical problems this could raise. We are then joined by Dr Matt Clark from the Natural History Museum, and Sir Jonathan Montgomery from University College London, to discuss the ins and outs of eDNA – how it can be beneficial for conservation, forensics and healthcare, but could also be problematic from a privacy perspective. Muriel Rabone and Dr Adrian Glover from the Natural History Museum have compiled an extensive checklist of all the species present in the remote Clarion-Clipperton Zone, which is an area twice the size of India, five kilometres deep in the Pacific Ocean. While you might expect this part of the sea to be devoid of life, the organisms that live there are surprisingly diverse, and we still know little about them. But the region is also chock-full of in-demand rare-earth metals. And we are joined by Dr Katie King to talk over some of her favourite science stories of the week, followed up by Helen Keen, who gets the kettle on to reveal more about the surprising physics behind a cup of coffee. Milk and two sugars for us, please. Presenter: Gareth Mitchell Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell

The Royal Society is the oldest scientific academy in the world. Since being established in 1660, it has painstakingly archived thousands of papers, letters, manuscripts and illustrations from some of science’s most enquiring minds.In this episode, Victoria Gill takes a trip to the society to pore over some of the most intriguing artefacts within its vaults. While there, she finds out more about the formation of the Royal Society and how science has been shaped over the centuries. Along the way, she considers the role of women in science, and asks whether their contributions have been historically overlooked.She is joined by the Royal Society’s Louisiane Ferlier and Keith Moore, along with Prof Uta Frith, a Royal Society Fellow and psychologist, and Dr Stephen Webster, a senior lecturer in science communication at Imperial College London. As part of its Science in the Making project, the Royal Society is currently digitising all of its collections, for everyone to browse through and enjoy. You can find out more on the Royal Society website.Presenter: Victoria Gill Producers: Harrison Lewis, Hannah Fisher Content Producer: Alice Lipscombe-Southwell
