NREL survey shows dramatic improvement in B100 biodiesel quality
The latest national survey of 100 percent biodiesel "blend stock" samples by the US Department of Energy's National Renewable Energy Laboratory found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications. The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers -- along with reliable operation of the nation's vehicles powered by biodiesel blends.

Plant protein puzzle solved
Researchers from North Carolina State University believe they have solved a puzzle that has long vexed science. The researchers provide the first three-dimensional model of an enzyme that links a simple sugar, glucose, into long-chain cellulose, the basic building block within plant cell walls that gives plants structure. Cellulose is nature's most abundant renewable biomaterial and an important resource for production of biofuels that represent alternatives to fossil fuels.
