The weight of water pumped from California's agricultural heartland, the Central Valley, over the past 150 years was enough to allow Earth's crust to rebound upward, raising surrounding mountain ranges, the Sierra Nevada and Coast Ranges, some six inches. Winter rains and summer pumping cause annual up and down movements that could affect earthquakes on the San Andreas Fault.
Rebecca Peters’ IQ score measured so low in fourth grade that her school did not deem her to be college material. Her parents didn’t buy it, and neither did she. Today she's a diehard clean-water-access warrior, the winner of three of America's top 10 scholarships -- and UC Berkeley's top graduating senior Also: University Medal runners-up find ‘turning point’ at Berkeley
The polar bear diverged from the brown bear, or grizzly, as recently as several hundred thousand years ago, according to a genome comparison by UC Berkeley, Chinese and Danish researchers. They pinpointed genes involved in fat metabolism that could provide insights that will help humans deal with health problems caused by high-fat diets.
New in ‘Breakthroughs’ from CNR: Food banks shift to better nutrition, UC team stamps out fires, and more
Berkeley's Center for Weight and Health reports that America's food banks are making progress in their efforts to give out more fresh, healthful foods, according to the College of Natural Resources' new edition of Breakthroughs magazine, which also features articles on a UC team fighting fires, the "king of quinoa" and more.
Initial results from Kelp Watch 2014, a project that tests kelp along the western U.S. coast for signs of radioactive seawater, has found no signs of ocean-borne radiation from Japan’s Fukushima nuclear power plant disaster. The project is a collaborative effort led by researchers at California State University, Long Beach, the Lawrence Berkeley National Laboratory and UC Berkeley.
Researchers at Berkeley Lab and UC Berkeley have recorded the first observations of a strong nonlinear optical resonance along the edges of single layers of molybdenum disulfide. The existence of these edge states is key to the use of molybdenum disulfide in nanoelectronics, as well as a catalyst for the hydrogen evolution reaction in fuel cells, desulfurization and other chemical reactions.
Physicist Saul Perlmutter led one of two large teams of astronomers who discovered distant supernovas lensed through massive galaxies. The discoveries offer an unprecedented opportunity for astronomers to study these gravitational lenses, which are used to provide a magnified view of the remote universe.
The magazine Technology Review named genome editing, invented by UC Berkeley's Jennifer Doudna and her colleagues, as one of 2014's top 10 technological breakthroughs. The magazine wrote that "the ability to create primates with intentional mutations could provide powerful new ways to study complex and genetically baffling brain disorders."
