Los Angeles, California - A team of researchers from the California NanoSystems Institute at UCLA has found a new way to use enzymes to remove pollutants from water that is cost- and energy-efficient, able to remove multiple pollutants at once, and minimizes risks to public health and the environment.

Los Angeles, California - A new computer algorithm can predict whether you and your spouse will have an improved or worsened relationship based on the tone of voice that you use when speaking to each other with nearly 79 percent accuracy.

Berkeley, California - The 2013 Yosemite Rim Fire was one of California’s largest wildfires in history, charring more than 257,000 acres. But the devastation also provided a rare opportunity for research.

Stanford, California - Many animals exhibit learned behaviors, but humans are unique in their capacity to build on existing knowledge to make new innovations. Understanding the patterns of how new generations of tools emerged in prehistoric societies, however, has long puzzled scientists.

Berkeley, California - The climatic and environmental effects of lava flows and sulfur emissions that lasted for years or decades in earth’s past were likely much less severe than scientists once thought, according to a new study by scientists in Europe and the United States.
