Amethyst, rose quartz, garnets, pearls…kidney stones? That’s right—it might just be time to add a lesser known formation to the list of gemstones you might want for your engagement ring.

Today, millions of people practiced their “drop, cover, and hold on” for the Great California ShakeOut. The annual earthquake drill, held a day after the anniversary of the 1989 Loma Prieta quake, celebrated its 10th birthday—with a twist. This year, for the first time, ShakeOut partnered with ShakeAlert 2.0, an earthquake early warning (EEW) system created in collaboration with the Seismology Lab at UC Berkeley.

The Global Climate Action Summit that wrapped recently in San Francisco was trumpeted as a “subnational” approach to climate change solutions, a riposte to the regressive environmental policies of the Trump administration.

The timber wars are heating up again in Northern California, this time at Rainbow Ridge, a tract of mature Douglas fir near the remote community of Petrolia in Humboldt County.

Curator of Paleontology at the museum, Irmis and others recently discovered this new dinosaur, an herbivore that roamed southern Utah 76 million years ago.

The recent capture of a suspect for the notorious Golden State Killer crimes was a vindication of both diligent detective work and modern technology. More than four decades after the first incident attributed to the GSK, which ultimately tallied at least 12 murders, 45 rapes, and more than 100 home burglaries, 72-year-old Joseph DeAngelo was arrested in his California home.
