What drives addicts to choose drugs, alcohol, cigarettes, gambling, overeating or kleptomania — despite the risks? Campus neuroscientists have pinpointed the locations in the brain where calculations are made that can result in addictive and compulsive behavior. Their astonishing findings could lead to improved treatments for many addictions and disorders.

The deep cultural ties that bind UC Berkeley and Norway inspired a call-to-action for greater collaboration on global energy challenges at the launch of Transatlantic Science Week 2011.

Watching a scary movie can motivate you to sell your stocks earlier than you would have otherwise. That’s the frightening evidence shown in a series of studies from the Haas Marketing Group.

A statewide survey by researchers at UC Berkeley’s Lawrence Hall of Science indicates that elementary school teachers don’t have the time or training to adequately teach science. “High quality science learning opportunities are only available in about 10 percent of California elementary school classrooms on a regular basis,” says lead researcher Rena Dorph.

UC Berkeley graduate student Greg Goldsmith may have his head in the clouds, but he is firmly grounded in the reality of global warming and the danger it poses to the Central American cloud forests he loves. He developed an elementary school curriculum as a way to help save them.

Record attendance at last week’s fifth-annual Energy Symposium at UC Berkeley demonstrated the swelling interest among students on campus and nationwide in bridging the gap between universities’ renewable energy research and the private sector.

UC Berkeley’s Solar Vehicle Team, is one day from successfully completing the 3,000-kilometer trans-Australia World Solar Challenge, which brought 37 solar cars to the Aussie outback. This is the first time Berkeley has competed.

The Berkeley Center for Green Chemistry will develop a new college course on the public ethics of green chemistry. The effort, funded by a $300,000 National Science Foundation grant, highlights the role of ethics in understanding why and how legal, market, business, political and societal systems can affect the chemical production system.

Plants called cycads flourished during the dinosaur era, but unlike the dinosaurs, they survived into the present and have been collected and treasured as “living fossils.” A new study by UC Berkeley biologists demolishes that idea. Living cycads are not “fossils” – they evolved only within the past 12 million years.
