  • Axolotl: The Monster God Who Refused to Grow Up
    Jul 7 2026

    Everything about the axolotl sounds like a cheat code: an animal that skips growing up, regrows lost limbs and even brain tissue, and appears to resist cancer far better than most vertebrates. This episode breaks down the real mechanisms, thyroid hormones, positional chemical gradients, a hair-trigger protein-building switch, behind those headline claims, plus a hard truth about its status in the wild.

    What you'll learn:

    - What neoteny actually means, using the axolotl as the textbook example

    - Why researchers can trigger metamorphosis in a lab and why doing so is risky for the animal - How a chemical gradient tells regenerating cells 'where' they are on a limb

    - The role of senescent 'zombie' cells and a tumor-suppressor gene in its regeneration story

    - Why this same animal is considered critically endangered in its only wild habitat

    Press play for the science, and stick around for the myth that started it all.
