Cognitive Functions of Men and Women

A University at Buffalo study, the first to use Positron Emission Tomography (PET) to compare the cognitive functions of men and women has found definitive evidence that although in many respects male and female brains operate in much the same way, they function differently when performing complex linguistic tasks.

First Demonstration Of Laser Action in a Powder

Scientists at Northwestern University have demonstrated lasing in a simple powdered material, suggesting that semiconductor lasers -- which are brighter and more efficient than light emitting diodes -- could be made cheaply enough to replace some of the 30 billion LEDs made each year for use in luminescent displays.
