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 ado...

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 conte...

This year’s Nobel prizes in chemistry, physics and physiology or medicine have celebrated work that has been used to develop countless drugs and transform modern medicine, allowed physicists to observe one of the most mysterious particles, and provided a tool that could act as an on/off switch for brain cells. To find out more, Madeleine Finlay talks to our science editor, Ian Sample, and correspo...

Several hospitals in eastern Russia are under quarantine after a lab worker fell ill at a plague research centre following a reported accident and died. Russia’s health watchdog has said Darya Shipilova, 28, died of ‘pneumonia of unknown aetiology’, but there is speculation about a possible plague infection. Science Weekly co-host Madeleine Finlay tells Lucy Hough, the host of Today in Focus: The...

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 brea...

Madeleine Finlay hears from Steve Ramirez, an associate professor of psychological and brain sciences at Boston University, whose book How to Change a Memory was shortlisted for this year’s Royal Society Trivedi science book prize. He explains how scientists have been able to locate memories in the brains of rodents, trigger them artificially and even remove them, and reveals what the practical ap...

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 pollutio...

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...

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 evolu...

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 expre...

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 understan...

In this episode of Science Weekly, recorded in front of an audience at the London podcast festival on 3 September, Ian Sample hears from Michael Safi, the host of the Guardian’s chart-topping podcast about artificial intelligence, Black Box. In series two, Black Box: the chatbots, Michael meets people who have become convinced they have made scientific breakthroughs, cured diseases or invented new...

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 Mad...

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 ex...

From the Guardian Investigates team: Across the world, hundreds of people have come to believe they have made extraordinary scientific discoveries with AI chatbots such as ChatGPT, Claude and Gemini. Others say their AI has ‘awakened’ or is leading them to a higher spiritual realm. The Guardian journalist Michael Safi begins investigating a phenomenon labelled ‘AI psychosis’, travelling to the US...

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...

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...

AI companies have promised us world-shifting technology. But there’s a cost: loud, unsightly datacentres that drain environmental resources. As the government pushes their rapid growth, can local communities do anything to push back? Madeleine Finlay speaks to the Guardian’s global technology reporter Aisha Down about the backlash to datacentres across the UK and around the world. Help support our...

Creatine has become the go-to supplement for anyone wanting to give their fitness a boost and build muscle. It’s even made it out of the gym, with influencers touting its cognitive benefits.

After a summer that has seen England and Wales experience the driest July since records began, rain is finally on the horizon. But with reservoirs at ‘exceptionally low’ levels, will there be enough rain to replenish stocks? Madeleine Finlay hears from Dr Anna Murgatroyd, a lecturer in hydrology at Newcastle University, about how much rain we need to see us through next summer, why we’re now at in...

One of the UK’s best fossil collections has been sold overseas in what experts have called a loss to the nation. The collection, which is now on display at the Natural History Museum in Abu Dhabi, was gathered on Dorset’s Jurassic Coast. As dinosaur fossils sell to private collectors for increasingly large sums, scientists are worried that domestic museums are being priced out of the market, and i...
