DOE Funds Joint BioEnergy Institute
With heady talk of embarking on a "Apollo" project for biological fuels, Energy Secretary Samuel Bodman unleashed three teams of scientists on a national hunt for clean liquid energy derived from plants and microbes. A year ago, Bay Area scientists decided to lead that hunt with an audacious bid to lure two giant biofuels institutes here, funded by tens of millions of dollars a year from BP LLC and the U.S. Department of Energy. On June 26, they clinched the second half of that double prize as Bodman named the Joint BioEnergy Institute, led by Berkeley Lab, as one of three national bioenergy centers to receive $125 million each over the next five years.

PBD Researchers Identify Photosynthetic Dimmer Switch
In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular “dimmer switch” that helps control the flow of solar energy moving through the system of light harvesting proteins. This discovery holds important implications for the future design of artificial photosynthesis systems that could provide the world with a sustainable and secure source of energy. Full story

Quantum Secrets of Photosynthesis Revealed
Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key – the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved. Full story
