Storms associated with atmospheric rivers have dumped record amounts of rain and snow in California this winter, resulting in flooding and other hazards.
The big picture: Atmospheric rivers direct tropical moisture, often from more than 1,500 miles away, toward the Golden State, where it is wrung out in the form of heavy precipitation.
At least two storm-related deaths were confirmed by state officials Friday as a powerful atmospheric river storm brought heavy rain and thunderstorms, and left thousands across Northern and Central California without power.
The big picture: The National Weather Service has warned of "copious amounts of heavy snow" in the mountains and potential flooding from a "high risk" of excessive rainfall. It's also increasingly likely that another significant atmospheric river event hitting central and northern California beginning on Monday.
A new map of a maggot's brain offers details about the wiring of neurons involved in learning — and could offer insights for powering AI in the same task.
Why it matters: The fly brain diagram will allow scientists to probe how the brain's hardware shapes behavior. It could also reveal circuits that evolved over hundreds of millions of years — and suggest ways to process information with less energy, a problem plaguing AI.
