The Master Switch in the Neural Grid: How a Worm Turns On Longevity by Mimicking Oxygen Starvation
Picture a master switch in an old house: one flip, and lights come on in every room. The tiny worm Caenorhabditis elegans has a similar switch, except instead of light it turns on a longevity program. The flip is a signal of oxygen shortage that triggers an ancient survival mechanism called the hypoxic response.
