Scientists studying hibernating animals have discovered that brains can shed and regrow synapses on demand — a finding that could revolutionize our understanding of brain plasticity, memory, and treatments for neurological disease. Here's what happens inside the brain of a sleeping bear, and why it might one day matter for yours.
The James Webb Space Telescope is detecting massive, fully-formed galaxies in the earliest epochs of the universe, challenging the standard model of cosmology and forcing scientists to confront whether our understanding of dark matter, galaxy formation, and the Big Bang itself needs a fundamental overhaul. Explore the discoveries upending decades of established science.
Scientists are uncovering how speaking multiple languages reshapes the brain from childhood through old age, building a powerful cognitive reserve that may delay dementia by years. Here's what the research reveals about multilingualism and long-term brain health.
Scientists have uncovered the real mechanisms behind quality sleep, from circadian rhythms to body temperature. Here's what the research says actually works.
