Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/5rqQFYdoSPWZ0QLQp27Rmj?si=nLAoFdo5SoSqJ7QoN3eUQQ The Sundown Archive holds the strangest scientific truths, laid out one at a time, meant to be read in a single long sitting. Get comfortable. Get the book: https://publy.store/t/wbpca93 Somewhere in your brain, the molecules that held your earliest memory were taken apart long ago, and the memory is still there. A slime mold with no brain braces for a cold breath of air that never comes. A moth carries a lesson from the caterpillar it used to be. So how does life remember? A slow walk from an operating room in 1953, through magnetized rock, slime and sea slugs, toward a question science has only half answered. Get cozy and let this long walk through the science of memory keep you company tonight. Subscribe to Sundown Science if you enjoy the long way around the universe.
