Pasadena CA - Mar 24, 2004When a friend asked Jorge Vazquez to speak eight years ago to a group of high school students about his job and Earth science, the JPL oceanographer reluctantly said yes. "I didn't think I'd like it," he says. Vazquez was right. He didn't like it: he loved it. Word got out, and before he knew it, he was getting calls from high school and junior high school teachers throughout the area. "I think they have some kind of network," he jokes. Artificial Prions Created 
San Francisco - Mar 23, 2004The culprit behind mad cow disease, a.k.a. bovine spongiform encephalopathy, is the most infamous mammalian form of prions. Prions are misfolded proteins that are capable of growing, replicating, and being passed on to daughter cells - that is, they are by themselves heritable. |

Spaceguard Redux, Put to Test
Moffett Field - Mar 22, 2004A small near-Earth asteroid (NEA), discovered Monday night by the NASA-funded LINEAR asteroid survey, made the closest approach to Earth ever recorded. There was no danger of a collision with the Earth during this encounter. Largely as a result of a Congressional mandate, NASA established a "Spaceguard" program with a goal of finding 90 percent of all the near-Earth asteroids (NEAs) larger than 1 kilometer in diameter by the end of 2008. Surviving With and Without Oxygen 
Moffett Field - Mar 22, 2004Christopher Chyba is the principal investigator for The SETI Institute lead team of the NASA Astrobiology Institute. Chyba formerly headed the SETI Institute's Center for the Study of Life in the Universe. His NAI team is pursuing a wide range of research activities, looking at both life's beginnings on Earth and the possibility of life on other worlds. Patagonian Ice Dam Studied From Space Cracks Open 
Paris - Mar 22, 2004A spectacle unseen for 16 years occurred in Patagonia this week: a natural dam of blue ice gave way to crushing lake waters trapped behind it, finally breaking apart. Rock Ahoy Near 'GEO' by Steven Chesley and Paul Chodas NASA's Near Earth Object Program Office
Pasadena - Mar 18, 2004A small near-Earth asteroid (NEA), discovered Monday night by the NASA-funded LINEAR asteroid survey, will make the closest approach to Earth ever recorded. There is no danger of a collision with the Earth during this encounter. Teeth tell the tale: Brits repelled Saxons 
London (UPI) March 17, 2004British scientists have proof Anglo-Saxons did not -- as most history books claim -- overrun native Britons 1,500 years ago. DNA Tests Refutes Neanderthal Ancestry Theory For Modern Humans 
Leipzig (UPI) March 16, 2004DNA analysis by researchers across Europe have yielded the best evidence yet Neanderthals made no significant genetic contributions to modern humans. Oceanic Acidity Influenced Early Carbon Dioxide Estimates
University Park - Mar 17, 2004An international team of geoscientists believes that carbon dioxide, and not changes in cosmic ray intensity, was the factor controlling ancient global temperatures. The new findings resulted from the researchers inclusion of the ocean's changing acidity in their calculations. |
Reflections On Life..In The Jungle
Edwards - Mar 16, 2004Brilliantly colored strawberry poison dart frogs singing in the jungle below didn't notice the NASA DC-8 flying laboratory passing overhead. After all, there is little disturbance to the rain forest by an aircraft far above. Clues To Life In The Mines Of Murgul 
Moffett Field - Mar 16, 2004The Mine of Murgul sounds like an ominous place in "The Lord of the Rings," a dark cavern filled with menacing orcs and trolls. But, in fact, this copper mine in Turkey may help shed light on life's origin. The mine contains pyrite, a form of iron sulfide (FeS2) also known as "Fool's Gold." This iron sulfide mineral may have acted as a template for the early chemical reactions that led to amino acids, proteins, and other building blocks of life. Dragons Of The Air: Pterosaurs Flew With Smart Wings Boulder 
Colorado - Mar 16, 2004These are the images of which nightmares are made: ancient pterosaurs darkening Earth's skies above the heads of dinosaurs during the Mesozoic era 225 million to 65 million years ago. America's Thirst Remains Stable

The Faces Of Globalization: A Dilemma For India 
Calcutta (UPI) Mar 12, 2004It's good for the economy; it creates employment, lots of it, and working nights at India's back offices is pleasing and financially rewarding for a huge number of young Indians. New Evidence Suggests Early Oceans Bereft Of Oxygen For Eons
Arlington - Mar 10, 2004As two rovers scour Mars for signs of water and the precursors of life, geochemists have uncovered evidence that Earth's ancient oceans were much different from today's. Viruses May Be Environmentally Friendly Decontaminants 
Baltimore - Mar 10, 2004Viruses could become the next generation of environmentally friendly decontaminants, replacing harmful chemicals like chlorine dioxide in cleaning up areas exposed to anthrax spores, according to findings released today at the American Society for Microbiology's Biodefense Research Meeting. |
