A unique experiment at Rice University that forces bacteria into a head-to-head competition for evolutionary dominance has yielded new insights about the way Darwinian selection plays out at the molecular level. An exacting new analysis of the exper…
Research conducted by scientists at the Hebrew University of Jerusalem and the U.S. Department of Energy’s Brookhaven National Laboratory has paved the way for development of highly efficient sensors for measuring blood glucose in diabetic patients. Particles the size of a nanometer (that is, one billionth of a meter), which are the building blocks of the science of nanotechnology, have comparable dimensions to animal or plant proteins, thus enabling the integration of these components into hybrid systems exhibiting novel properties.
Energy Secretary Spencer Abraham and Under Secretary of State for Global Affairs Paula Dobriansky will be joined by representatives from several invited countries to announce plans for an international forum to advance carbon and storage technologies. In addition, Secretary Abraham will announce a government-sponsored, public-private partnership to create the world’s first pollution-free, fossil fuel fired power plant. The announcements follow a briefing to the President by Secretary Abraham, Secretary of State Colin Powell and Environmental Protection Agency Administrator Christine Todd Whitman.
In a modern-day odyssey of exploration, researchers from the Department of Energy’s Idaho National Engineering and Environmental Laboratory endured grueling shifts on remote ocean drill rigs to get frozen cores of mud. Then came painstaking lab work, analyzing the microbial inhabitants of the deep seafloor sediment. The reward: discovering new life and gaining new insight into the microscopic creators of the largest frozen methane pools on the planet.
