Is your boss watching you? The rise of AI surveillance at work Oct 15, 2026

Show notes

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.

The surprising psychology of morbid curiosity Oct 13, 2026

Narcolepsy: why you’ve been thinking about it all wrong Oct 06, 2026

Show notes

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? Sep 29, 2026

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.

Are baby girls more sociable? Super El Niño, meningitis outbreak explained Sep 24, 2026

Show notes

Madeleine Finlay sits down with her co-host and Guardian science editor, Ian Sample, to discuss three science stories from the week, including a study that offers a clue in the age-old debate about whether sex differences are present from birth or a product of socialisation. Also on the agenda is the super El Niño, which is predicted to lead to 450,000 deaths in the next six months, and an answer to why the UK’s meningitis outbreak earlier this year was so big..

From paleo to intermittent fasting: are any diets actually good for us? Sep 22, 2026

Show notes

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. Help support our independent journalism at theguardian.com/sciencepod
