Where Science Meets the Herd We put on a pair of “cattle vision” goggles to see how livestock perceive their world. Learn why understanding that is better for the animal and the rancher.

From "cattle vision goggles" to goat-handling machines that let the animals "be with a friend," our latest episode explores new tools to help people see how livestock perceive their world, helping them and the people who raise them. Listen now! @katkerlin.bsky.social

Opinion | NASA Flew by the Moon, but Behind the Scenes, Its Science Is a Chaotic Mess

The images of Earth from Artemis are amazing. But if we destroy our ability to understand (and live on) our planet, all they are is pretty pictures

Managed Wetlands a Culinary Hot Spot for SF Bay Fish, But They Need Delivery Options A UC Davis study shows that part of the San Fransisco Estuary is teeming with fish food — the managed wetlands of Suisun Marsh. Timing seasonal flood releases from them could feed more fish.

Bird Flu Strikes California Elephant Seals for the First Time Thirty seals, primarily weaned pups, have died since late last week, scientists said.

A lethal form of bird flu, which has already killed tens of thousands of elephant seals in the Southern Hemisphere, is now spreading in a colony of elephant seals in California, scientists said on Wednesday.

Frog Love Songs and the Sounds of Climate Change A good love song tells female frogs when the time is right for mating, finds a UC Davis study showing male frogs change their tune as the weather warms.

Some called it the "Christmas Valley miracle" when that Tahoe community and Meyers were spared during 2021's Caldor Fire. A @ucdavis.bsky.social study reveals which pre-fire treatments worked best to ⬇️ the fire damage. Also: Unburned fuel piles are a big problem. www.ucdavis.edu/climate/news...

Ps. These fish are not “reintroduced.” They are finding their way home because restored habitat is rolling out a welcome mat.
