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...

Green Energy for the Battlefield

The amount of energy the United States consumes increases every year and this growth in energy consumption outpaces energy production. To fill this gap, the U.S. imports 35% of its energy. More importantly, the U.S. imports over 60% of its total oil consumption. Added to this, 70% of this energy is from...
