UCLA Scientists Wake Up Dormant Hair Follicles, Promising a Cure for Baldness

2025-02-07

UCLA scientists have developed PP405, a small molecule that reactivates dormant hair follicles, offering a potential cure for baldness. Nearly a decade of lab work culminated in promising 2023 human trials, showing topical application of PP405 stimulates growth of healthy, full-length hair, unlike other treatments. Led by three researchers, the breakthrough has spurred the creation of a company backed by Google Ventures to pursue further trials and FDA approval, offering hope for millions suffering from hair loss.

M87 Supermassive Black Hole Emits Astonishing Gamma-Ray Flare

2024-12-16

In 2019, the Event Horizon Telescope captured the first-ever image of a supermassive black hole at the center of galaxy M87. Now, an international team, including researchers from UCLA, has observed a teraelectronvolt gamma-ray flare from this black hole, tens of millions of times larger than its event horizon. This rare, decade-defining flare provides crucial insights into particle acceleration near black holes and could help solve the mystery of cosmic ray origins. UCLA played a significant role in the construction and data analysis of the VERITAS telescope, instrumental in detecting this event.
