( 03/29)
Cheap, plastic solar cells that can be painted onto just about any surface could provide power for a range of portable and even wearable electronic devices, scientists said Thursday.

Arsenic In Well Water Related To Atherosclerosis
( 03/28)
Long-term exposure to ingested arsenic -- a contaminant in artesian well water in many parts of the world -- has been linked to heart attacks, strokes and diseased arteries in the body's extremities, according to a study in today's rapid access Circulation: Journal of the American Heart Association.

Scientists Say "Grace" As Water-Sensing Satellites Lift Off
( 03/20)
NASA and the German Center for Air and Space Flight successfully launched the Gravity Recovery and Climate Experiment, or "Grace," mission into Earth orbit at 1:21:27 a.m. Pacific time on March 17, 2002 from Russia's Plesetsk Cosmodrome. The mission, comprised of identical twin satellites, will precisely measure Earth's shifting water masses and map their effects on Earth's gravity field.
