Scientists Use Iron In New Global Warming Tests (Yahoo! News2/28)
"New tests have shown that the injection of iron into the Southern Ocean could reduce the build-up of carbon dioxide gases that lead to global warming, New Zealand scientists said Friday. The iron significantly boosted the growth of phytoplankton which in turn absorbed much more of the greenhouse gas carbon dioxide, New Zealand's National Institute of Water and Atmospheric Research (NIWA) said."
Better Ideas about Martian Surface Colors Provide Clues About Martian Water (Science Daily 2/28)
"NASA Hubble Space Telescope images of Mars taken in visible and infrared light detail a rich geologic history and provide further evidence for water-bearing minerals on the planet's surface."
Mapping of Mars to Begin in March (CNN 2/26)
"The Mars Global Surveyor satellite will start its main mapping mission of the red planet in March, NASA said this week."
Robotic Rover, Spacesuited Geologist Work Together In Test Of Future Exploration (Science Daily 2/26)
"NASA is testing a remotely operated planetary rover and an advanced prototype spacesuit in southern California this week to see how robots and humans might someday work best together to explore other planets."
Who Benefits From Climate Forecasts Columbia Scientists Tackle Thorny Question (Science Daily 2/26)
"Private Use of Information in Peru Yields Unintended Consequences. Scientists can now predict with some degree of accuracy such extreme climate perturbations as El NiŅo. The next question, say two researchers at Columbia University and a third at the National Center for Atmospheric Research, is how to translate those scientific findings into benefits for societies affected by climate variability."
NSF To Establish "Cybersystem" For Earthquake Engineering Simulation (Science Daily 2/24)
"A top National Science Foundation [NSF] official today (Feb. 23) described to a House subcommittee how the NSF plans to use information technology [IT] to establish a cyber Network for Earthquake Engineering Simulation [NEES].
Giant Ocean Eddies Discovered (Science Daily 2/22)
"Dramatic ocean eddies larger than Tasmania and a kilometre deep have been discovered in the Indian Ocean, north-west of Australia."
Experts Say Italy's Mount Etna May Erupt (CNN 2/21)
"The tallest and most active volcano in Europe, Mount Etna, has issued an intermittent stream of rocks, ash and lava since July. Researchers now say they have discovered a fracture on the volcano's northeastern side, just under the main crater, which may indicate the mountain is changing shape. "
What's this volcano trying to tell us? (New Scientist 2/20)
"Deep gurgles and belches from far underground could be the early warning volcanologists have been waiting for. Daniel Pendick listens in."
Experiments Shows Life May Have Come From Space (Yahoo! News 2/18)
"Scientists said Thursday they may have demonstrated a way that life on Earth could have been ''seeded'' from outer space. They cooked chemicals commonly found in space under simulated sunlight, and found compounds important to life, including alcohols and ethers, formed. It is only a few steps from there to form amino acids, the basic building blocks of proteins, which make up all life."
Ancient Volcanic Cataclysms Discovered In The Indian Ocean (Science Daily 2/18)
"Scientists from the largely National Science Foundation (NSF) supported Ocean Drilling Program (ODP) have completed an expedition to one of the most remote places on Earth, the Kerguelen Plateau. The results of their expedition will shed new light on how and when continents formed and broke apart millions of years ago.
"Hell On Earth" And CSIRO's Going There (Science Daily 2/16)
"It's a blistering 300 degrees, it lies at the bottom of the ocean -- and Australian scientists have just been given the go-ahead to help explore it. In August 2000 Dr Ray Binns from CSIRO will set sail in a world-first expedition on JOIDES Resolution, a specially equipped scientific drilling vessel operated by the renowned international Ocean Drilling Program (ODP). "
Replaying life (New Scientist 2/13)
"At last, we can watch evolution happen over and over again in the microworlds of the lab. And in playing God, we are laying bare the very forces that shape all living things, says Kate Douglas."
After a Sizzling Year and a Very Warm Decade, Scientists Consider the Global Warming Question (The Why Files 2/5)
"When the global warming debate first heated up in the late 1980s, scientists warned that the Earth our grandkids walked might be cooking like a fried egg on an El Paso sidewalk. The prediction ran like this: Gathering levels of greenhouse gases in the atmosphere would trap heat, causing a rapid warming and damaging the atmosphere, the oceans and the economy.
