  • Can we eradicate a second human disease?

    Can we eradicate a second human disease?
    Apr 7 2026
    The number of human cases of guinea worm, a painful and debilitating tropical illness, fell to a record low of just 10 last year, according to the Carter Centre, the foundation set up by the late former US president Jimmy Carter. But despite years-long declines, it remains almost impossible to completely eradicate the parasite. Only one human illness has been entirely eradicated: smallpox. Why is it so difficult, and could guinea worm one day be the second? Ian Sample hears from co-host Madeleine Finlay, and David Molyneux, emeritus professor of tropical disease microbiology at the Liverpool School of Tropical Medicine.

    Sauna and cold plunge: where does the evidence stand?
    Apr 2 2026

  • Transporting the most expensive and volatile substance on Earth

    Transporting the most expensive and volatile substance on Earth
    Mar 26 2026
    A box the size of a filing cabinet was lifted by crane, slowly moved and placed very carefully in the back of an unassuming lorry earlier this week. What looked like a casual drive around the Cern campus was actually a world-first experiment in transporting antimatter, the most expensive and volatile substance on Earth. To find out why scientists wanted to achieve this milestone, and what happened on the journey, Madeleine Finlay hears from the Guardian’s science editor, Ian Sample, and the Cern physicist Dr Christian Smorra..

  • Does going to the moon still matter?

    Does going to the moon still matter?
    Mar 31 2026
    If all goes to plan, Artemis II, Nasa’s mission to return humans to the moon, will launch this week. The mission will mark the farthest that humans have travelled from Earth, and the first return to the moon in more than 50 years. It will also pave the way for landing on the moon again as soon as 2028. But given the Apollo missions have already achieved that feat, does going back to the moon still matter today? To find out, Madeleine Finlay hears from the Guardian’s science editor, Ian Sample, the Atlantic journalist Ross Andersen, and Jan Wörner, a former director general of the European Space Agency.

  • What sets human consciousness apart from AI?

    What sets human consciousness apart from AI?
    Mar 24 2026
    Why is it like something to be ourselves and how do physical processes create our subjective experience? These questions get to the heart of the knotty problem of consciousness, and they provided the spark for the latest book from award-winning author and journalist Michael Pollan. In A World Appears, Pollan goes in search of answers about what we do and don’t know about consciousness, and why it has proven such an elusive phenomenon. He tells Ian Sample how thoughts and feelings shape our conscious experience, whether we can learn anything about human consciousness from AI, and why he thinks our minds need to be defended in today’s technology saturated world.

  • Off Duty: The Crime

    Off Duty: The Crime
    Mar 21 2026
    On the evening of 29 December 2011, police officer Clifton Lewis was moonlighting as a security guard at a Chicago minimart when two men walked in. They shot Lewis several times, then took off with his gun and police star. A week later, police had their suspects: four men affiliated with a gang called the Spanish Cobras. For hours, under intense police questioning, they all said they did not do it. But that did not seem to matter. This is episode one of Off Duty, an investigation by the Guardian’s Melissa Segura.

  • What’s behind the injectable peptide craze?

    What’s behind the injectable peptide craze?
    Mar 17 2026
    Grey-market injectable peptides – a category of substances with obscure, alphanumeric names such as BPC-157, GHK-Cu, or TB-500 – have developed a devoted following among biohackers and health optimisers. To understand how these unregulated substances have become mainstream and what they could be doing in our bodies, Madeleine Finlay hears from journalist Adrienne Matei and from Dr Anna Barnard, an associate professor at Imperial College London who researches peptides.
