Forestry scientists are working to understand how wildfire and other “disturbances” affect the health of some of the oldest trees on the plant — the giant sequoias of the Sierra Nevada.

The debate over the veracity of global warming may be judged not by pure science but rather, perception. Being in a warm room can make the idea of global warming seem more likely, according to Clayton Critcher, assistant professor of marketing at the Haas School of Business.

Inspired by the 50th anniversary this year of the Peace Corps, UC Berkeley is launching a 21st century version called Cal Energy Corps that focuses on sustainable energy and climate change.

Producing cheap liquid biofuels is not the only challenge in weaning the U.S. off fossil fuels. A team supported by the Energy Biosciences Institute identified social, economic and environmental issues that need to be addressed, including the impacts on farmers and on public health.

In a demonstration of “reverse-ecology,” UC Berkeley biologists have shown that one can determine an organism’s adaptive traits by looking first at its genome and checking for variations across a population. The study offers a powerful new tool in evolutionary genetics research, one that could be used to help monitor the effects of climate change and habitat destruction.

Sequencing of microbes in the rumen of the cow has turned up a treasure trove of new enzymes that degrade tough plant material, providing new avenues for research to boost biofuel production from plants. The research, funded by the Energy Biosciences Institute, involves UC Berkeley chemical engineer Doug Clark and colleagues at LBNL and the Joint Genome Institue.

A study by the Haas School’s Yuan Sun and colleagues at UC Davis and the University of Otago, New Zealand, found that the stock value of a company typically drops when it increases carbon emissions. The finding supports arguments that firms should be required to disclose to investors any action that impacts climate change.

The secrets behind the mysterious nano-sized electromagnetic “hotspots” that appear on metal surfaces under a light are being revealed with the help of a BEAST. The results hold promise for solar energy and chemical sensing among other technologies.

Hundreds of visitors flocked to a new, 420-square-foot cottage in West Berkeley to examine the tiny, sustainably designed “accessory home” as a possible wave of the future.

Jay Keasling, a leading authority on metabolic engineering, envisions a future in which microorganisms are tailor-made to produce specific chemical products, such as biofuels and pharmaceuticals, from inexpensive and renewable starting materials. He has written a paper on the subject for the journal Science.

The International Union for Conservation of Nature this year singled out the University of California's system of 36 natural reserves — a haven for the state's diverse ecosystems and species for nearly half a century — as one of the "20 best biodiversity success stories." Read more about the efforts by the reserves to reintroduce and foster the survival of endangered and threatened species.

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.

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.

UC Berkeley researchers have created unique dual-diameter nanopillars – narrow at the top, broad at the bottom – that absorb light as well or even better than commercial thin-film solar cells, using far less semiconductor material and without the need for anti-reflective coating.
