    Jun 18 2025

    https://youtu.be/dRkqXHvU71o

    The Polyfloss team is back with a game-changer: a mini plastic recycling machine small enough for your workshop. Matt reconnects with co-founders Audrey Gaulard, Émile De Visscher, and Christophe Machet to discuss how they're putting plastic recycling directly into people's hands - and why that matters.

  • 268: Biocomputers - The Next Step for AI?
    Jun 4 2025

    https://youtu.be/kAYdIpcDnZk

    Today is a very brainy conversation. Matt had the chance to chat with Dr. Kyle Wedgwood and research intern Wiktor Wiejak from University of Exeter in England. Wedgwood’s a mathematician specializing in neuroscience, and he’s using a computer from FinalSpark. Matt just put out a full video on what’s special about these computers, but in short, they’re alive. They’re made up of bundles of neurons, also known as organoids, and Dr. Wedgwood is using them to explore what he calls “the fundamentals” of how neurons work.
