Across our planet, natural archives preserve the biological footprints of species long gone, from woolly mammoths at the macro scale, through plants and seeds, to dormant bacteria and viruses at the micro end of the spectrum. And one environment that safeguards some of this material in the best condition of all is the cold - in other words, in ice. So, this week, we're going to look at what is sitting in nature's deep freeze... Like this podcast? Please help us by supporting the Naked Scientists

This week: social media's role in user harm and the plausibility of app addiction, a sunken Soviet sub revealing how nuclear materials behave deep underwater, a hidden "magnetic shadow" on the Moon that could improve space travel safety, and the science behind the famous "waggle dance" performed by honeybees....

Coming up, we explore the race back to the Moon. Why are we going? How will we get there? Can we live and work on its surface? And what can we grow when we get there? We explore the science, the engineering, and the possibilities of humanity's next giant leap... Like this podcast? Please help us by supporting the Naked Scientists

Coming up, we explore an outbreak of meningitis in the English county of Kent. Will a targeted vaccination campaign bring it under control? Plus, a fast diagnostic swab test that may help diagnose schizophrenia, how thousands of old tumour samples could aid our understanding of rising bowel cancer rates in people under 50, and a new study that suggests ultrasound could help save European hedgehogs from road traffic...

For Endometriosis Awareness Month, we explore a condition which affects 10% of women around the world. Cells that form the lining of the uterus crop up in other parts of the pelvis, and elsewhere in the body. It prevents many patients from being able to carry out everyday tasks, and can also cause infertility. In this episode, we explore the condition, hear the experiences of those living with endometriosis, discuss the science behind it, and find out about the treatments of tomorrow... Like this podcast?

Coming up, we assess the environmental and health impact of conflict in the Middle East. Plus, the gene variants that affect how heavily someone smokes, a medication called ruxolitinib that could help the vitiligo community, and a fascinating new study on interbreeding between Neanderthals and humans...

This week, we're exploring polio: a highly infectious viral disease that can attack the nervous system and cause paralysis, mainly in young children. Polio has been pushed to the brink of elimination thanks to global vaccination efforts - but it still persists. In this episode, we'll look at what polio is, how vaccines have helped control it, where the virus still exists today, and whether it can finally be eradicated... Like this podcast?

Coming up, we explore how CAR-T cell therapy is revolutionising personalised cancer treatment. Plus, how NASA's DART mission tested Earth's asteroid defence, what we are learning about the benefits of breastfeeding for mother and baby health, and we delve into the physics behind squeaky shoes...

Our Titans of Science series continues with Mike Wooldridge, Ashall Professor of Foundations of Artificial Intelligence at the University of Oxford. He has conducted extensive work in the field of agentic AI, systems comprising multiple interacting AIs. In this episode, he tells Chris Smith what drew him to computers and AI in the first place, the pioneering work of Geoff Hinton, why ChatGPT isn't made to speak the truth, and what's in store for us as AI continues to develop...
