## Resource

Scientists have uncovered a surprising functional role for the pigment that gives red hair its color, revealing it may quietly protect cells in ways no one expected. A major new study links uninterrupted sitting to a significantly higher cancer mortality risk, while fresh research from Cedars-Sinai adds to the growing case that coffee is quietly protecting your liver. Astronomers have spotted 31 previously unknown ancient quasars, offering the clearest look yet at supermassive black holes that somehow grew enormous just after the Big Bang. Meanwhile, a landmark genetic discovery caught a 'jumping gene' traveling between species through dead cells—something scientists didn't think was possible—and researchers have finally explained, at the atomic level, why gold never tarnishes.
