    • Where did our attention spans go, and can we get them back?
      Jan 9 2025
      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 not beyond rescue, and reveals her top tips for finding focus.

    • Are we hardwired to commit ‘deadly sins’?
      Jan 7 2025
      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?
      Jan 2 2025
      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, Zoe’s chief scientist, the University of Oxford academic dietician Dr Nicola Guess, and 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.
