Science Weekly ·

2025/02/04

Senators are scheduled to vote today on whether to advance Robert F Kennedy Jr’s nomination as Secretary of State for Health and Human Services. RFK Jr is known for his vaccine skepticism and Make America Healthy Again slogan, which has won him support from everyone from wellness fans and ‘crunchy moms’ to traditional Republicans. US health reporter Jessica Glenza tells Ian Sample about how he fared at last week’s confirmation hearings, and what he might do if he takes a seat in Trump’s cabinet

Telepathy…what’s the evidence?

2025/01/21

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,

2025/01/09

The Oxford English Dictionary announced its word of the year at the end of 2024: brain rot. The term relates to the supposedly negative effects of consuming social media content, but it struck a chord more widely with many of us who feel we just don’t have the mental capacity we once did. Gloria Mark, a professor of informatics at the University of California, Irvine, has been studying our waning attention spans for 20 years. She tells Madeleine Finlay why she believes our powers of concentration

Are we hardwired to commit ‘deadly sins’?

Science Weekly ·

2025/01/07

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.

Revisited: does the evidence on glucose tracking add up?

Science Weekly ·

2025/01/02

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

Revisited: just how bad is alcohol for us?

Science Weekly ·

2024/12/31

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

2024/12/26

In 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

Dr Chris van Tulleken has been at the forefront of the campaign to change our food system and better regulate the sale of ultra-processed foods (UPF). This year he will be giving the Royal Institution Christmas lectures, Britain’s most prestigious public science lectures, in which he’ll be investigating how food has fundamentally shaped human evolution, the importance of our microbiome – as the extra ‘organ’ we didn’t know we had – and how we can all eat better in future, for the sake of our own

Is our model of the universe wrong?

2024/12/17

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

2024/12/12

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?

What if you could take a pill or a shot that could reduce your blood alcohol level and make you feel better in the morning? That’s the promise of a range of wellness products aiming to be the next big hangover antidote. But what exactly are hangovers, and which methods of preventing them are backed by science?
