Physicists have made an accidental discovery in the lab that has potential to change how information in computers can be transported or stored. Dependent on the "spin" of electrons, a property electrons possess that makes them behave like tiny magnets, the discovery could help in the development of spin-based semiconductor technology such as ultrahigh-speed computers.
Cooperative System Could Wipe Out Car Alarm Noise

The persistent, annoying blare of an ignored car alarm may become a sound of the past if a cooperative, mutable and silent network of monitors proposed by Penn State researchers is deployed in automobiles and parking lots.
Capturing DNA Molecules In A Nanochannel

An electric voltage can be used to propel DNA molecules through a channel a few nanometers deep, or to stop them in their tracks. In a strong electric field the molecules judder along the channel, while in weaker fields they move more smoothly. This enables DNA fragments to be 'captured' on a chip and separated for analysis.
Robot That Climbs In The Pipe

Industrial pipe systems are inaccessible and narrow. The pipes can be vertical and have junctions. Just as challenging, leakage points in the water system must be located, the condition of oil and gas pipelines must be checked and ventilation systems need to be cleaned.
Hard X-ray Nanoprobe Provides New Capability To Study Nanoscale Materials

The Center for Nanoscale Materials' newly operational Hard X-ray Nanoprobe at the US Department of Energy's Argonne National Laboratory is one of the world's most powerful X-ray microscopes. It has been designed to study novel nanoscale materials and devices aimed at, for example, harvesting solar energy more efficiently, providing more efficient lighting, or enabling next-generation computing.

It is better to go to the house of mourning than to go to the house of feasting.
Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles.
It shouldn't be too much of a surprise that the Internet has evolved into a force strong enough to reflect the greatest hopes and fears of those who use it. After all, it was designed to withstand nuclear war, not just the puny huffs and puffs of politici
