    The real science of weight loss with the US’s leading nutritional scientist
    Oct 7 2025
    Kevin Hall spent 21 years at the US National Institutes of Health and became known globally for his pioneering work on ultra-processed foods. In April he unexpectedly took early retirement, citing censorship under the Trump administration. Now he has co-authored a book with the journalist Julia Belluz that aims to bust myths and challenge wellness orthodoxy on everything from weight loss and metabolism to supplements and wearables. Hall tells Ian Sample what he wants us all to understand about diet, exercise and weight loss, and what led to his departure from the job he loved.

  • Does a bit of booze really make us better at languages?

    Does a bit of booze really make us better at languages?
    Sep 30 2025
    The Ig Nobel prizes were awarded recently – for science that makes you laugh and then think – and the peace prize was given to a cheeky study testing the link between alcohol and language proficiency. Does a drink really help us to converse more convincingly in another tongue, or does it just give us inflated confidence? To find out, Madeleine Finlay speaks to a member of the winning team, Dr Fritz Renner, a researcher in clinical psychology and psychotherapy at the University of Freiburg in Germany.

  • Fact-checking Trump’s autism announcement

    Fact-checking Trump’s autism announcement
    Sep 24 2025
    In a televised press conference on Monday, Donald Trump and health secretary Robert F Kennedy Jr made a series of unproven claims about autism and its links to paracetamol use in pregnant women, and about childhood vaccinations. The comments were immediately refuted by scientists and health agencies around the world, but many expressed concern about the impact of this misinformation being repeated at the highest levels of government. So what does the science really say? Madeleine Finlay speaks to Guardian science editor Ian Sample to factcheck the claims made in the announcement, and find out what decades of scientific research into autism tells us about its causes and why diagnoses are on the rise.

    Is there hope on the horizon for patients with Alzheimer’s?
    Sep 23 2025
    A trial is under way to find out if a £100 blood test could transform the way that the NHS diagnoses Alzheimer’s disease. Alzheimer’s is the leading cause of dementia and diagnosis is currently costly and time-consuming. To find out how this blood test could benefit patients, Ian Sample talks to Prof Jonathan Schott, who is co-leading the trial. He explains what the test involves and why it could pave the way for exciting new treatments for the devastating disease. Help support our independent journalism at theguardian.com/sciencepod

  • Is the US on the brink of a new era of political violence?

    Is the US on the brink of a new era of political violence?
    Sep 18 2025
    The murder of political activist Charlie Kirk has prompted fears about rising levels of political violence in the US after a number of high-profile assassinations and attempted assassinations of political figures in recent years. But how connected are these events and do they signal a rise in public support for this kind of violence? To find out Ian Sample speaks to Sean Westwood, an associate professor in political science at Dartmouth College and director of the Polarization Research Lab. He explains how political violence has evolved and why overestimating the support for such acts can be dangerous. Help support our independent journalism at theguardian.com/sciencepod
