  Is your boss watching you? The rise of AI surveillance at work 15.10.2026 17min

  Workers have always been monitored by their bosses, first through output targets, and then via computer software labelled ‘bossware’. But AI is transforming the capabilities of these systems, processing huge volumes of data to provide minute-by-minute accounts of activity, and productivity. To find out more, Ian Sample hears from UK technology editor Robert Booth. He explains which sectors are adopting this approach, why they are doing it, and how it could end up being counterproductive..

  The surprising psychology of morbid curiosity 13.10.2026 17min

  US defence secretary Pete Hegseth’s plan to livestream the execution of Nidal Malik Hasan has incurred condemnation from human rights groups and politicians on all sides. But according to Coltan Scrivner, an author and psychologist at Arizona State University and expert on morbid curiosity, people are still likely to watch in large numbers. He explains why we are drawn to dark and disturbing content, and Madeleine Finlay tells Ian Sample how consuming this kind of material can harm observers’ mental health.

  Narcolepsy: why you’ve been thinking about it all wrong 06.10.2026 16min

  The sleep disorder has been the butt of jokes and a comedic plot point, but the reality of living with narcolepsy is anything but funny. Things could be about to change for people with the condition though, after the US Food and Drug Administration (FDA) approved the first ever drug to treat narcolepsy itself, rather than just its symptoms. Madeleine Finlay tells Ian Sample how the scientific breakthrough came about, and Julie Flygare, who has narcolepsy and founded the non-profit Project Sleep, explains what it is like to live with the condition and how the drug could be gamechanger.

  Are household cleaning products damaging our health? 29.09.2026 17min

  Our use of cleaning products has increased since the pandemic, but do we understand what they could be doing to our health? The journalist Rebecca Seal recently wrote for the Guardian about the potential impacts of the many chemicals we now use in our homes. She tells Madeleine Finlay how social media has also played a role in transforming our cleaning habits, why the impact of indoor air pollution is so hard to study, and what the current evidence is that cleaning products may be causing harm.

  From paleo to intermittent fasting: are any diets actually good for us? 22.09.2026 17min

  As diet trends proliferate on social media, it can be hard to work out which are backed by science and which should be ignored. From paleo to keto, raw food to intermittent fasting, each attracts a tribe of ardent followers. Now Daniel Lieberman, professor of biological sciences at Harvard University, has written a book to try to cut through the noise. In Fed Up, he uses his background as an evolutionary anthropologist to scrutinise the evidence, turning himself into a guinea pig in the process and trying various diets. In this podcast, he tells Ian Sample which one has remained part of his routine.

  The week that changed maths for ever 17.09.2026 15min

  In early September, OpenAI announced it had solved a major mathematics problem that has stumped humans for nearly a century. The news left mathematicians reeling, and many expressed concern over what will be left for humans as AI becomes ever more adept at unravelling complex problems. Now 25 recipients of the Fields medal – often called the Nobel prize for maths – have signed an open letter expressing their fears of a ‘severe misalignment’ between AI companies and their field. To find out how AI is likely to upend maths – and how mathematicians might respond – Ian Sample speaks to Colva Roney-Dougal, professor of pure mathematics at the University of St Andrews.

  Is collagen all hype? 15.09.2026 18min

  Collagen powders, gummies and pills have boomed in popularity in recent years boosted by claims that they smooth wrinkles, promote glossy hair and help with joint pain. Amid the noise it can be hard to figure out whether there’s any actual science behind the promise of looking younger for longer. Luckily Dr Xand van Tulleken has spent the past three years writing Make me well: a quest to understand the confusing world of wellness, and his chapter on collagen dives deep into the evidence. He tells Madeleine Finlay what collagen does in the body, how we can get it without splashing out on expensive supplements, and why getting to the truth behind wellness claims can be so hard.

  ‘One of the biggest discoveries in science’: have scientists found dark matter? 10.09.2026 16min

  For decades physicists have been puzzling over the enigma of dark matter. We think it makes up 85% of the matter in the universe, but the mysterious substance cannot be seen or detected, and we know about it mainly through observations of the gravitational effects it has on other things. But now scientists believe they may be a step closer to detecting it. Science editor Ian Sample explains to Madeleine Finlay why, if confirmed, the finding could completely transform our understanding of the universe. And Dr Samuel Eriksen, senior research associate at the University of Bristol, and first author of the research paper, explains how the finding has been received in the physics community.

  Are rich people really worse behaved? Here’s the science 08.09.2026 18min

  Who’s more likely to steal sweets from a child? According to science, it’s the rich. A study seemingly confirming our suspicions about the moral behaviour of the wealthy was one of the winners of the 2026 Ig Nobel prizes, which honour research that makes you laugh and then think. Science editor Ian Sample tells Madeleine Finlay what the researchers think could be behind the phenomenon, and they explore some of the other awards, including one for a surprising quality we look for in our friends and another for a biomechanical definition of kissing.

  There’s a quick way to slow climate change. Why isn’t everyone doing it? 03.09.2026 13min

  Methane is a potent greenhouse gas that traps more than 80 times as much heat than carbon dioxide over a 20-year period and causes 25% of global heating today. We definitely don’t want this gas spewing needlessly into the atmosphere, but in 2023 that’s exactly what environment editor Damian Carrington found was happening when he reported on 1,000 super-emitting methane leaks across the globe. Now Turkmenistan, the worst country for mega-leaks, has begun to plug them. Damian tells Madeleine Finlay why some experts call stopping leaks the climate ‘emergency brake’ and reveals which countries are still failing to act.

  Could humans ever communicate with whales? 01.09.2026 17min

  Ever since the earliest known recording of whale song was made in 1949, researchers have been captivated by the wails, rumbles, clicks, grunts and squeals of their communication. As technology improves, scientists are decoding the intricate patterns that make different species’ vocalisations distinctive. Madeleine Finlay hears from Emma Bryce, a journalist who has spent months investigating human efforts to understand whale song. She explains how this knowledge could help us better protect whales from human-made harms. Credits: 1. Copyright 1978 National Geographic Society and 1977 Capitol Records, Inc.
