In a first-of-its-kind study, Lawrence Berkeley National Lab scientists tracked the amount of lead transported across the Pacific over time. About a third of the airborne lead particles recently collected at two sites in the Bay Area came from Asia. The finding underscores the far-flung impacts of air pollution.
A clean-energy initiative in rural Nicaragua shows that developing nations can take cost-effective steps to reduce carbon emissions while helping the rural poor to reduce their energy expenses, according to researchers at UC Berkeley. Their report inScience analyzes simple steps taken by Nicaraguan government and the nonprofit blueEnergy on that country's Mosquito Coast.
Holiday travel can leave people cranky and tired, in part because of jet lag, the result of your body's internal clock being out of synch with your current time zone. For chronic travelers, it's more than a passing annoyance, however. A new study shows that chronic jet lag can cause long-term brain changes that lead to memory and learning problems for at least a month after return to a normal schedule.
Astronomers using three telescopes atop Mauna Kea in Hawaii have recorded the return of a unique belt on Jupiter that periodically fades from dark brown to white. It's most recent fade-out started earlier this year, but November observations show the brown returning. It appears that reflected sunlight off high elevation clouds of ammonia ice have been blocking our view of the darker clouds below.
The same basic biological mechanism that helps athletes develop endurance on a treadmill may someday help to save and improve the lives of patients with traumatic brain injuries, according to UC Berkeley Professor George Brooks and colleagues at UCLA. ScienceMatters@Berkeley describes the research and its potential medical application.
UC Berkeley economic historian Barry Eichengreen, an expert on the international monetary and financial system, discussed the Irish economic crisis at a campus seminar Nov. 17. He said Ireland needs to restructure much of the bank debt that its government has effectively taken onto its balance sheet — debt that could reach a staggering 130 percent of GDP in the coming year.
The particle accelerators at CERN in Geneva produce scads of antiprotons, which five years ago were combined at high speed with positrons to create for the first time antimatter atoms: antihydrogen. Those atoms annihilated with normal matter within microseconds, but an international team involving UC Berkeley and LBNL physicists has succeeded in slowing such atoms down and trapping them for a tenth of a second. This will allow experiments on a type of matter that hasn't been available since shortly after the Big Bang 14 billion years ago.
Dire or emotionally charged warnings about the consequences of global warming can backfire if presented too negatively, making people less amenable to reducing their carbon footprint, according to new research from UC Berkeley.
As part of a federal initiative to examine the environmental factors influencing children's health, UC Berkeley will receive three federal grants totalling $16.5 million. Work at three School of Public Health centers will be supported by the grants.
