  • 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..

  • What sets human consciousness apart in the age of AI?

    What sets human consciousness apart in the age of 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.
