In 2012, UC Berkeley paleontologist Anthony Barnosky and 20 co-authors published a dire paper warning that Earth’s climate is approaching a tipping point that could irrevocably drive the planet into a scary and uncertain future.
Daniela Kaufer, PhD, is an associate professor at UC Berkeley who studies the biology of stress, examining at the molecular level how the brain responds to anxiety and traumatic events. Her most recent findings show that certain kinds of stress can have surprising benefits. Dr. Kaufer explains the difference between good stress and bad stress, and gives pointers for how to respond to stressful events in a healthy way.

“The original focus on fish oil and omega-3s came from studies of Inuit. On their traditional diet, rich in fat from marine mammals, Inuit seemed quite healthy with a low incidence of cardiovascular disease, so fish oil must be protective,” said project leader Rasmus Nielsen, a UC Berkeley professor of integrative biology. “We’ve now found that they have unique genetic adaptations to this diet, so you cannot extrapolate from them to other populations.
Professor Robert Dudley has discovered a new type of nocturnal hunting spider from South America that is able to steer while it glides to the ground, unlike other spiders that just drop.

The analysis, using the most comprehensive genetic data set from Native Americans to date, was conducted using three different statistical models, two of them created by UC Berkeley researchers. The first, developed by the lab of Yun Song, a UC Berkeley associate professor of statistics and of electrical engineering and computer sciences, takes into account the full DNA information available from the genomes in the study.
"When I went foraging with Philip Stark and Tom Carlson for what became the first of the California Matters series of videos, I had an idea of what to expect.
Research by Professor Brent Mishler and IB graduate student Caleb Caswell-Levy on ‘Resurrection Plants’, desiccation-tolerant mosses and their associated rotifers which can survive long dry spells and spring back to life when exposed to water, is the focus of a video and story on KQED public television.
