New Clues To Origin Of Life
Edmonton - Apr 26, 2004A new discovery of microbial activity in 3.5 billion-year-old volcanic rock and one of earth's earliest signs of geological existence sheds new light on the antiquity of life, says University of Alberta researchers who are part of a team that made the groundbreaking finding. "People have been looking for signs of early bacteria for the last 50 years," said Dr. Karlis Muehlenbachs. |

Kalispell, Mont - Apr 26, 2004Earth Search Sciences' CEO Larry Vance says he is pleased with the results that Noranda Inc. has accomplished using ESSI's revolutionary remote sensing technology. |
Black Magic Or Just Fancy Silicon
Pasadena (JPL) Apr 26, 2004In his office at NASA's Jet Propulsion Laboratory, Optics Engineer Larry Scherr sits before a buzzing computer, sketching geometrical shapes on a sheet of graph paper. He is calculating lens shapes to control the path of light rays. A Little Science, A Lot Of Driving 
Stanford - Apr 26, 2004It's the tale of the princess and the pea, science-style. Proteins sitting on a glass microscope slide can have a hard time getting comfortable. Atop a bed of compact silica, they can become confined, contorted and damaged -- and may even lose their biological functions. |
Gravity Probe B Powered Up And OK
Huntsville - Apr 26, 2004Gravity Probe B � a NASA mission to test two predictions of Albert Einstein's Theory of General Relativity � is orbiting 400 miles above Earth, and all spacecraft systems are performing well. Its solar arrays are generating power, and all electrical systems are powered on. Outta Here At Last 
Stanford - Apr 26, 2004Airborne at last! Forty-five years after its conception and 41 years after its initial funding, the Gravity Probe B (GP-B) experiment has finally launched. On April 20 at 9:57 a.m., a Boeing Delta II rocket sent the probe 400 miles high and into polar orbit from Vandenberg Air Force Base in Southern California. |
Bruce Moomaw Reports On Mars Science At Astrobiology 2004
Mountain View CA - Apr 22, 2004The third of NASA's Astrobiology Science Conferences -- held every two years at Ames Research Center in Mountain View, California -- has just ended. Every one of these has drawn a considerably bigger crowd of scientists than the previous one. This might seem peculiar for what one scientist has described as "the most lively scientific field not to have any actual subject material yet". |
Arctic Ozone Loss More Sensitive To Climate Change Than Thought
Pasadena - Apr 26, 2004A cooperative study involving NASA scientists quantifies, for the first time, the relationship between Arctic ozone loss and changes in the temperature of Earth's stratosphere. Portable Rainbow Source Improves Color Calibrations 
Washington - Apr 26, 2004If you need bright blue light at a very specific wavelength, the National Institute of Standards and Technology (NIST) can make it---and fast. In the world of color, this is no small accomplishment. NIST's traditional light sources, such as incandescent lamps, are thermal. |
Multinational Team of Scientists Finds Early Life in Volcanic Lava
San Diego - Apr 26, 2004 Scientists from the United States, Norway, Canada, and South Africa have identified what is believed to be evidence of one of Earth's earliest forms of life, a finding that could factor heavily into discussions of the origins of life. Ancient Pebbles Provide New Details About Primeval Atmosphere 
Stanford - Apr 26, 2004Analysis of 3.2-billion-year-old pebbles has yielded perhaps the oldest geological evidence of Earth's ancient atmosphere and climate. The findings, published in the April 15 issue of the journal Nature, indicate that carbon dioxide levels in the early atmosphere were substantially above those that exist today and above those predicted by other models of the early Earth. |
