California’s San Joaquin Valley produces an enormous share of the nation’s fruits, nuts and vegetables. But it takes an unsustainable amount of groundwater to do it. New state rules aimed at reducing groundwater use are expected to force up to 20 percent of the valley’s irrigated fields out of production – a blow to farmers and communities.

After months of fieldwork and scientific analysis, National Park Service researchers have determined that the coyote that drew international attention in early 2026 after swimming to Alcatraz Island likely started his epic swim from Angel Island State Park.

The coyote’s whereabouts remain unknown, but new DNA evidence has helped park staff answer one of the biggest questions surrounding the unusual sighting: where he came from.

In the summer of 2020, MJ Farruggia embarked on the first field season of her PhD research. With a backpack full of scientific equipment and camping gear, she hiked high into the Emerald Lake Watershed high in the Sierra Nevada Mountains to install environmental sensors and collect water samples from six small lakes and ponds.

Would You Let Your Utility Control When You Charge Your EV?

Katherine E Kerlin — April 20, 2026 - 9:15am

Electric vehicles are one important way for America to use less fossil fuels — driving down emissions that cause climate change and reducing exposure to oil price shocks that threaten economic growth. But as more households buy electric cars, they must also charge those cars, which typically happens at night. So many EVs charging at once can put a strain on local electric grids. Some utilities are trying to lessen this burden by scheduling EV charging themselves, spreading charging out so that fewer vehicles need power all at once.

Bird Flu Outbreak Among CA Marine Mammals Remains Small But Concerning

For every bad thing happening in the world, there are good people trying to make things right. Sometimes they even win. That’s why I’m starting a new series on this blog called “Tell Me Something Good.”

I’m opening it up with Carson Jeffres, a 51�ԹϺ�� Davis Center for Watershed Sciences researcher who helped inspire the idea, simply by telling me something good. I needed to hear it. Maybe you do, too.
