## Resource

Researchers at the University of Virginia have found a way to crack open the blood-brain barrier using focused ultrasound to deliver genetic molecules directly to glioblastoma tumors — and the early results are turning heads. A teenager with a devastating genetic epilepsy is now walking independently after a two-year treatment targeting the root cause of their condition. A massive new study reveals that Ozempic and Mounjaro users are experiencing a measurable uptick in hair loss, and scientists think they know why. Underwater drones off the coast of Benin have uncovered a coral reef that scientists declared dead in the 1960s — very much alive and thriving 50 meters below the surface. Plus: light-controlled electronics, a brain-mimicking chip faster than thought, and what your hippocampus is doing when you're not paying attention.
