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...
