Low-Cost LED Lighting

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...

Wearable Kidney

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...

Centennial Challenges

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,...

Swimsuit or Spacesuit?

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...

Brain Mapping

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...

Laser Microscalpel

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...
