U.S. group makes cheap plastic solar-energy cells
- 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
- 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.
Giant octopus caught off New Zealand

Black Water off the Gulf Coast of Florida
- This image of black water off the coast of Florida was acquired on March 20, 2002, by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Scientists and local fishermen are not sure what is coloring this typically turquoise water black. Amid growing concern, scientists are now trying to determine the source of the black water.
Scientists Say "Grace" As Water-Sensing Satellites Lift Off
- 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.
New giant iceberg adrift near Antarctica
- A new iceberg -- one roughly twice the size of the state of Rhode Island -- is adrift in the icy waters off Antarctica, the National Ice Center says.
"Buried Dams" Help Clean Recycled Water
- Disease-causing microbes can effectively be eliminated from recycled water by storing it underground, new research by CSIRO scientists has found. Promising research findings into natural ways to cleanse polluted water have brought Australia a step closer to a revolution in water reclamation ö the ăunderground damä.
Future Volcanic Eruptions May Cause Ozone Hole Over Arctic
- An "ozone hole" could form over the North Pole after future major volcanic eruptions, according to the cover story by a NASA scientist in tomorrow's edition of the Proceedings of the National Academy of Sciences.
Cataclysm 3.9 Billion Years Ago Was Caused By Asteroids, Not Comets, Researchers Say
- The bombardment that resurfaced the Earth 3.9 billion years ago was produced by asteroids, not comets, according to David Kring of the University of Arizona Lunar and Planetary Laboratory and Barbara Cohen, formerly at the UA and now with the University of Hawaii. Their findings appear today in the Journal of Geophysical Research - Planets, published by the American Geophysical Union.
