EPA foregoes opportunity to improve nanotechnology oversight
The U.S. Environmental Protection Agency released its current thinking on whether a nanoscale material is a "new" or "existing" chemical substance under the Toxic Substances Control Act (TSCA). view more (2007-07-13)
Expert says nanotechnology should look to Mother Nature
Professor Richard Jones of the University of Sheffield has today outlined the possibilities of using nature's secrets to develop nanotechnology, and casts doubt on some popular assumptions about the science, including the premise that we may create nano-robots with the power to reduce the world to 'grey goo'. Professor Jones is internationally... view more... (2004-08-11)
Heavier hydrogen on the atomic scale reduces friction
Scientists may be one step closer to understanding the atomic forces that cause friction, thanks to a recently published study by researchers from the University of Pennsylvania, the University of Houston and the U.S. Department of Energy's Argonne National Laboratory. view more (2007-11-05)
