Self-powered devices possible, says Texas A&M researcher
Imagine a self-powering cell phone that never needs to be charged because it converts sound waves produced by the user into the energy it needs to keep running. It's not as far-fetched as it may seem thanks to the recent work of Tahir Cagin, a professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University.  12/2/08

MIT researchers fired up about battery alternative
Massachusetts Institute of Technology | EurekAlert!
Just about everything that runs on batteries -- flashlights, cell phones, electric cars, missile-guidance systems -- would be improved with a better energy supply. But traditional batteries haven't progressed far beyond the basic design developed by Alessandro Volta in the 19th century. Until now. Work at MIT's Laboratory for Electromagnetic and Electronic Systems holds out the promise of the first technologically significant and economically viable alternative to conventional batteries in more than 200 years. 2/7/2006

Adding nanotubes makes ordinary materials absorb vibration
Rensselaer Polytechnic Institute | EurekAlert!
A new study suggests that integrating nanotubes into traditional materials dramatically improves their ability to reduce vibration, especially at high temperatures. The findings could pave the way for a new class of materials with a multitude of applications, from high-performance parts for spacecraft and automobile engines, to golf clubs that don't sting and stereo speakers that don't buzz. 2/7/2006

Turbulence yields secrets to 73-year-old experiment
University of Illinois at Urbana-Champaign | EurekAlert!
A simple but groundbreaking experiment performed more than 70 years ago finally has been explained by scientists at the University of Illinois at Urbana-Champaign. The solution sheds new light on fluid turbulence -- the last major unsolved problem in classical physics. 1/30/2006

New Doubts Are Cast on Einstein's Cosmological Constant
Dennis Overbye | New York Times
An astronomer said the force known as dark energy was not constant, as Albert Einstein would have predicted, but was growing more violent.  1/11/2006

Stricter Nanotechnology Laws Are Urged
Rick Weiss | RedOrbit News
An independent report being released this morning concludes that current U.S. laws and regulations cannot adequately protect the public against the risks of nanotechnology -- the rapidly growing science of making invisibly small particles and molecular devices.
Unless existing laws are modified or a new one is crafted, the report warns, the immense promise of the field -- predicted to be a trillion-dollar industry by 2015 -- may be short-circuited by either a disaster or an economically damaging crisis of public confidence.
"There is a chance to still do this right and learn from previous mistakes," said study author J. Clarence Davies, an environmental policy analyst who played major roles in the Johnson, Nixon and first Bush administrations and is now with Resources for the Future, a nonpartisan think tank on environmental and energy issues.     1/11/2006
