Neuroscience breakthrough, next-level watch news, a celebration of Mexican craft and more from around the web

Neuroscientists Observe The Formation of a Memory in a Living Brain A team of scientists from the University of Southern California watched zebra fish forming “fearful” brain memories, an observation that revealed a complex system of synaptic rewiring. The neuroscientists witnessed this overhaul of connections through imaging under a microscope, where memories blossomed in a fluorescent green color. This breakthrough, which, according to Wired, supports …

The Link Between Nostalgia and Pain Relief

Scientists behind research outlined in a new paper published in the Journal of Neuroscience believe there’s a connection between nostalgia and pain relief. The study (helmed by a team at University of the Chinese Academy of Sciences in Beijing and titled Thalamocortical mechanisms for nostalgia-induced analgesia) involved an experiment in which participants had slight heat applied to their skin, they then rated their pain levels, …

This Glove-Like Device Encourages Lucid Dreaming

Though still in development trials, the new “Dormio” device invented by MIT researchers shows potential for aiding lucid dreaming—or more specifically, hypnagogic microdreams. Using the “steel ball technique” (popularized a century ago and used by Salvador Dalí and Thomas Edison) as a starting point, the team built a biometric glove-like device that identifies the onset of sleep, and subsequently attempts influencing oncoming dreams based on …
