BBC Inside Science

A shortage of medical isotopes used to detect cancer has experts concerned that the shortfall could be delaying diagnosis and could even be costing lives. Exactly what these nuclear medicines are and how they are made is key to understanding the national scarcity. So, we’re going back to basics and learning all about medical isotopes. We also speak to world-famous conservationist and primatologist Jane Goodall who, now aged 90, continues to travel the globe campaigning to protect the natural world. Dame Goodall reflects on a life of studying our closest living animal relatives, chimpanzees, and as COP29 gets under way, speaks about the “closing window of time” to turn the tide on climate change and nature loss. Also this week, we answer the listener question “Why don’t we just throw nuclear waste into volcanoes?” and can Marnie spot AI vs real poetry?

This year is set to be the world’s hottest on record, likely shattering the aspiration to limit global warming to 1.5C above pre-industrial levels. So where does this leave COP29, the upcoming UN climate conference in Azerbaijan? This week Inside Science is asking, are climate summits really working? What is the point of them - and are they doing enough? Joining Marnie Chesterton to discuss this are: - Joanna Depledge, expert on international climate negotiations at the University of Cambridge - Mark Maslin, climate change professor from University College London (UCL) - Jim Watson, professor of energy policy, also from UCL Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston & Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth If you want to test your climate change knowledge, follow the links on this page to The Open University to take a quiz.

It’s our Halloween special from a rain-soaked Jodrell Bank in Cheshire. We find out what you can see in a dark, dark Halloween night sky with space-watcher and Professor of astrophysics Tim O’Brien. Also this week, we meet some blood-sucking leeches, the horrors of pumpkin waste and could zombies ever be real?

Twenty years ago this week two physicists at the University of Manchester published a ground-breaking paper describing the extraordinary qualities of graphene. The thinnest and strongest material known to exist – and better at carrying electricity than any metal – its discovery was hailed as revolutionary. But two decades on, it doesn’t seem to have changed the world, or if it has, it is doing so very quietly. So, what happened? We go on the trail of graphene, meeting Nobel Prize winner and Godfather of Graphene Andrew Geim, and learning what it has – and hasn’t – done and what might be next... Also this week, how to kill an asteroid and we talk the “other” COP with chief scientific adviser to the government, Dame Angela McLean.
