Episodes

The science of laughingMadeleine Finlay speaks to Sophie Scott, a professor of cognitive neuroscience at University College London, to dig into the science of laughter. Sophie explains what exactly laughter is, the many different purposes it serves for humans and animals, and how prioritising it could make us all feel a little better.

Does Google’s ‘mindboggling’ new chip bring quantum computers any closer?On Monday Google unveiled its Willow quantum computing chip. The new chip takes just five minutes to complete tasks that would take 10 septillion years for some of the world’s fastest conventional computers to complete. But despite its impressive power, it’s not clear the chip has any practical applications. So does it bring quantum computing any closer? To find out Ian Sample speaks to Winfried Hensinger, professor of quantum technologies at the University of Sussex. Because of industrial action taking place by members of the National Union of Journalists at the Guardian and Observer this week, you may notice some disruption to the availability of new episodes in your Guardian podcast feeds in the coming days. All the work on this episode was done before the strike action began. For more information please head to theguardian.com. Help support our independent journalism at theguardian.com/sciencepod

Is our model of the universe wrong?For the past 10 years cosmologists have been left scratching their heads over why two methods for measuring the universe’s rate of expansion provide totally different results. There are two possible solutions to the puzzle, known as the Hubble tension: either something is wrong with the measurements or something is wrong with our model of the universe. It was hoped that observations from the James Webb space telescope might shed some light on the problem, but instead results published last week have continued to muddy the waters. To understand why the expansion rate of the universe remains a mystery, and what might be needed to finally pin it down, Madeleine Finlay speaks to Catherine Heymans, the astronomer royal for Scotland and a professor of astrophysics at the University of Edinburgh.

Revisited: are the world’s oldest people really that old?In this episode from September, Madeleine Finlay speaks to Dr Saul Newman, an interdisciplinary researcher at University College London and the University of Oxford, who has recently won an Ig Nobel prize – given to scientific research that ‘first makes people laugh, and then makes them think’ – for his work showing that many claims of people living extraordinarily long lives come from places with short lifespans, no birth certificates, and where clerical errors and pension fraud abound.

Revisited: the endless sexual diversity of natureIn this episode from July, Ian Sample talks to Josh Davis, a science writer at the Natural History Museum in London and author of the book A Little Gay Natural History. A study published in June 2024 suggested that, although animal scientists widely observe same-sex sexual behaviour in primates and other mammals, they seldom publish about it. Josh considers why this might be and describes some of his favourite examples of sexual diversity from the animal kingdom.. Help support our independent journalism at theguardian.com/sciencepod

Revisited: just how bad is alcohol for us?For the regular drinker, the studies that say a daily tipple is better for a longer life than avoiding alcohol completely are a source of great comfort. But a new analysis challenges that thinking and says it was based on flawed research that compares drinkers with people who are sick and sober. In this episode from August, Madeleine Finlay hears from the study’s lead author, Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research at the University of Victoria, to find out why scientists (including him) were so convinced, and what the actual risks of alcohol are.

Revisited: does the evidence on glucose tracking add up?You might have noticed that everyone has recently become a bit obsessed with blood sugar, or glucose. Wellness firms such as Zoe in the UK – as well as Nutrisense, Levels and Signos – claim to offer insights into how our bodies process food based on monitoring our blood glucose, among other things. But many researchers have begun to question the science behind this. In this episode from July, Ian Sample talks to the philosopher Julian Baggini, the University of Oxford academic dietician Dr Nicola Guess, and Zoe’s chief scientist the King’s College London nutrition expert Prof Sarah Berry to find out what we know about blood glucose levels and our health, and whether the science is nailed down on personalised nutrition.

Are we hardwired to commit ‘deadly sins’?Scientists are increasingly finding that behaviours once seen as depraved often have a direct physical cause. To find out more, Ian Sample hears from Guy Leschziner, a consultant neurologist and sleep physician at Guy’s and St Thomas’ hospital in London. His new book, Seven Deadly Sins: The Biology of Being Human, looks at the neurological basis of behaviours often dismissed as evidence of bad character or lack of willpower.

Our science predictions for 2025Last year was full of unexpected science news, from a new strain of Mpox emerging in the DRC, to artificial intelligence dominating the Nobel prizes and two astronauts getting ‘stuck’ in space. So what will this year bring? Ian Sample and science correspondent Hannah Devlin discuss the big stories likely to hit the headlines and share their predictions for 2025.

Telepathy…what’s the evidence?A podcast promoting claims that non-verbal autistic children can read minds briefly knocked Joe Rogan off the top of the charts this month, which made the Science Weekly team wonder, how has science attempted to prove or disprove the existence of mind reading? To find out, Ian Sample speaks to Chris French, emeritus professor of psychology at Goldsmiths University. They discuss how scientists have tested this phenomenon, what else could be behind the apparent ability of some people to read minds, and why the idea is still so popular.
