Daniela Kaufer, professor of integrative biology at the University of California, Berkeley, shared progress toward addressing another cause of cognitive decline: dysfunction of the blood-brain barrier. The blood-brain barrier ordinarily protects the brain, but Kaufer’s work shows that when the barrier falters, itself a sign of aging, proteins can enter brain cells called astrocytes, which causes inflammation in the brain and leads to cognitive impairments.
According to lead scientist on the project and Miller Postdoctoral Fellow at UC Berkeley Alejandro Rico-Guevara, physical traits observed in male hummingbirds in the tropics of Central and South America could not be explained through adaptations to feeding strategies.
Alexander Stubbs of the University of California, Berkeley, and Fernando Montealegre-Z of the University of Lincoln in England studied a recording of the sounds made by diplomats and published by The Associated Press.
Using high-speed video cameras, the researchers have for the first time captured hummingbird fencing and feeding strategies in slow motion to document the various ways the birds use their bills to fight and the trade-offs they accept when choosing fighting over feeding prowess.
Geckos are renowned for their acrobatic feats on land and in the air, but a new discovery that they can also run on water puts them in the superhero category, says a University of California, Berkeley, biologist.
“We just have a decade or two given the rapid pace of climate and land-use change,” said Brent Mishler, a UC Berkeley professor of integrative biology and director of the University and Jepson Herbaria. “Our opportunities, even 10 years down the line, are way more limited compared to what they are now. What we are going to save, we are going to save quickly. We don’t have forever to leisurely conserve California.”

UC Berkeley doctoral student Emily King is studying the behavior of New Zealand mud snails to find a way to stop their infestation.
The tiny black dots on the soggy leaf that Emily King plucked out of Mount Diablo Creek the other day did not look very threatening, but the UC Berkeley biologist knows well how looks can be deceiving.
