Scientists and engineers at the Energy Department and its national laboratories are finding new, more efficient ways to convert biomass into biofuels that can take the place of conventional fuels like gasoline, diesel and jet fuel. At Oak Ridge National Laboratory's Environmental Science Division, graduate students and researchers use transplanted trees in a number of studies, including those involving biomass conversion to biofuels. In this photo, graduate student Alina Campbell is removing damaged leaves from Eastern Cottonwood trees, which helps stimulate the trees' growth.| Photo courtesy of Jason Richards.
