Seeing the big picture in photosynthetic light harvesting
Berkeley Lab scientists have created the first computational model that simulates the light-harvesting activity of thousands of antenna proteins that would interact in the chloroplast of an actual leaf. The results point the way to improving the yields of food and fuel crops, and developing artificial photosynthesis technologies for next generation solar energy systems.

Technique matters: A different way to make cathodes may mean better batteries
Lithium nickel manganese cobalt oxide, or NMC, is one of the most promising chemistries for better lithium batteries, especially for electric vehicle applications, but scientists have been struggling to get higher capacity out of them. Now researchers at Lawrence Berkeley National Laboratory have found that using a different method to make the material can offer substantial improvements.

Renewable energy for state renewable portfolio standards yielded sizable benefits
A new study estimates that billions in dollars in benefits come from reduced greenhouse gas emissions and from reductions in other air pollution for state renewable portfolio standard policies operating in 2013. RPS policies require utilities or other electricity providers to meet a minimum portion of their load with eligible forms of renewable electricity.

Cool roofs in China offer enhanced benefits during heat waves
It is well established that white roofs can mitigate the urban heat island effect, reflecting the sun's energy back into space and reducing a city's temperature. In a new study of Guangzhou, China, Lab researchers Dev Millstein, Ronnen Levinson, and Pablo Rosado working with Chinese scientists found that during a heat wave, the effect is significantly more pronounced.

Nature's masonry: The first steps in how thin protein sheets form polyhedral shells
Scientists have for the first time viewed how bacterial proteins self-assemble into thin sheets and begin to form the walls of the outer shell for nano-sized polyhedral compartments that function as specialized factories. The new insight may aid scientists who seek to tap this natural origami by designing novel compartments or using them as scaffolding for new types of nanoscale architectures, such as drug-delivery systems.

Some like it hot: Simulating single particle excitations
Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Researchers with Berkeley Lab have used a real-time numerical algorithm to study both the plasmon and hot carrier within the same framework. That is critical for understanding how long a particle stays excited, and whether there is energy backflow from hot carrier to plasmon.

New results from world's most sensitive dark matter detector
The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility in the Black Hills of South Dakota, has already proven itself to be the most sensitive detector in the hunt for dark matter, the unseen stuff believed to account for most of the matter in the universe. Now, a new set of calibration techniques employed by LUX scientists has again dramatically improved the detector's sensitivity.
