Pacific Northwest researchers have used a nuclear magnetic resonance microscope imager to obtain chemical information from a living cell without destroying the cell or invading it in the process. And for the first time researchers have been able to do this also on the cell nucleus, the internal control center of the cell. The work is part of a study to understand the impact of the environment, and contaminants in the environment, on human life and health. Electric bus of the future A new motor controller with advanced soft-switching circuitry developed at DOE's Oak Ridge National Laboratory promises to make electric and hybrid vehicles more practical. The 100-kilowatt inverter and controller, which are being tested aboard an electric bus in Chattanooga, Tenn., represent breakthroughs in several areas, including cost, volume, weight and reliability.
