Purdue University researchers have uncovered a potentially less expensive method to produce solid-state lighting based on light-emitting-diode (LED) technology. This development could hasten the day when LEDs, which are more energy efficient and longer lasting than conventional incandescent light bulbs, become the preferred...

Researchers from UCLA and the Veterans Affairs Greater Los Angeles Healthcare System have developed a design for an automated, wearable artificial kidney, or AWAK. Around 1980, a similar artificial kidney machine was built which was portable, but not wearable. The new technology would allow patients to go about their regular...

NASA's program of technology prizes consists of seven competitions held throughout the year. The program began in 2005 and is known as Centennial Challenges, in recognition of the centennial of powered flight. The prizes are offered to independent competitors who work without government support, including small businesses,...

Researchers at Auburn University's Samuel Ginn College of Engineering have produced antimicrobial coatings with potential to prevent diseases from spreading on contaminated surfaces - possibly solving a growing problem not only in hospitals but also in schools, offices, airplanes and elsewhere. The Auburn researchers mixed...

Researchers at the University of Saskatchewan have opened an engineering lab to design a ventilation system that could protect schools, hospitals, and other public buildings from chemical warfare and bioterrorist attacks. The lab's research will help determine how the Early Warning and Response system (eWAR) can both filter...

Compressed air stored in underground caverns could answer the need for lower cost electrical energy, according to Sandia National Laboratory scientists. The scientists are examining the feasibility of using an aquifer site near Des Moines, IA, to power a plant able to generate up to 13,400 megawatts per hour with...

Scientists at the ETH Zurich Departments of Mechanical and Process Engineering and Computer Science have teamed with supercomputingexperts at IBM's Zurich Research Laboratory to develop an accurate, powerful and fast method to automate the analysis of bone strength. The method combines density measurements with...

Swimmers around the world are breaking records this year like never before, including at this week's U.S. Olympic trials. Some attribute it to extensive training as athletes prepare to compete at this summer's games in Beijing, China. Others, however, say one factor may be a new space-age swimsuit made of fabric tested at...

An international team of researchers has created the first complete high- resolution map of how millions of neural fibers in the human cerebral cortex - the outer layer of the brain responsible for higher level thinking - connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to...

Scientists at the University of Texas at Austin have developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. The device uses femtosecond lasers, which produce extremely brief, high-energy light pulses...

A compact sensor for measuring temperature and pressure in a combustion chamber has been proposed. Heretofore, independent measurements of high pressures and temperatures in combustion chambers have not been performed. In the original intended application, the combustion chamber would...

The C6 perfluoroalkyl formulation overcomes the environmental issues inherent in other perfluoroalkyl tails, and imparts non-stick properties and resistance to oil, grease, solvents, or water that are similar to C8 fluoroalkyl tails. Chemicals containing perfluoroalkyl tails are used for stain,...
