A  class of chemical compounds used for flavor and fragrance may one day become a clean, renewable resource with which to fuel our automobiles. U.S. Department of Energy researchers have modified the E. Coli bacteria to create large quantities of methyl ketone from glucose. First tests of this methyl ketone show very high cetane numbers. Cetane is a fuel rating system for diesel fuel, similar to octane ratings for gasoline. This makes the methyl ketones a viable candidate for production...

Discovery paves the way for new synthesis of antibiotics Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules — a mechanism that has baffled organic chemists for decades. Their result, reported today in Nature, details how five carbon atoms and one oxygen atom in the structure of lasalocid, a natural antibiotic produced...

Offshore Wind Farms Vulnerable To Hurricanes

In a world of green energy aficionados, offshore wind farms have become all the rage. Yet with the U.S. poised to invest untold billions in the environmentally friendly power source, a recent study has caused many to question the financial liabilities associated with what now seems a very risky investment. According to a study published Monday in the Proceedings of the National Academy of Sciences, yearly offshore hurricanes would likely destroy roughly half of the proposed wind turbines...

In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers can be produced in high volumes at low cost, resulting in photovoltaic devices that are cheap, lightweight and flexible. In the last few years, much work has been done to improve the efficiency with which these devices convert sunlight into power, including the development of new materials, device...
