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. ...I learned about eating dandelion leaves, roots, and the base where they met, as well as crowns and even the little balls of unbloomed flowers (actually the best part, sautéed). I learned, too, about milkweed, a plant that can be eaten at several stages."
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.
Published today in the journal Bioscience, the report outlines how illegal marijuana production is hitting California where it hurts, such as in sensitive watersheds already stressed by the state’s ongoing drought. Networks of pipes and hoses siphon water directly from small streams to irrigate the crops, draining what little water there is for wildlife and plants.
Dubbed “veloci-roach,” the crawling device uses sensors and locomotion like many other bio-inspired devices.
But this one flips on its side to shimmy through spaces that would normally prove too small, according to Chen Li, postdoctoral researcher in the UC Berkeley department of integrative biology, and electrical engineering and computer science.
An ancient human skeleton called Kennewick Man, found on the banks of the Columbia River in 1996, has been at the center of a dispute between Native Americans and scientists on the disposition of the remains. A new analysis of DNA from the bones by a team that includes Professor Rasmus Nielsen concludes that the man probably was an ancestor of local Native American tribes. Read More
Cold-blooded and other animals that are unable to regulate their internal temperature may have a hard time tolerating global warming, according to an analysis by biologists from the University of California, Berkeley, and San Francisco State University.
Two Integrative Biology Graduate Students, Joyce Chery and Roxanne Cruz-de Hoyos, are recipients of the 2015 Distinguished Fellows Video Contest and will receive funds for conference travel.

Berkeley, California - Two thousand California honey bees may have a story to tell. So too, more than 10,000 deer mice, and 3,000 oaks. Specimens of these plants and animals populate massive collections in Berkeley’s renowned research museums, and are now being enlisted as guides to past episodes of habitat and climate change.
Plant ecologist David Ackerly has calculated that some animals and plants would need to migrate as much as four miles a year to track their preferred temperature in a rapidly warming climate.
