Arlington VA - Apr 21, 2004The Arctic Ocean receives about 10 percent of Earth's river water and with it some 25 teragrams [28 million tons] per year of dissolved organic carbon that had been held in far northern bogs and other soils. When Did Bacteria Appear? 
Moffett Field - Apr 21, 2004The bacteria family tree may be facing some changes due to the recent work of an evolutionary biologist at Washington University in St. Louis. And that may change our understanding of when bacteria and oxygen first appeared on earth. |

Making A Friendlier Mosquito
Davis CA - Apr 21, 2004Genetically modified mosquitoes that cannot transmit malaria are one hope for battling the disease that still kills over one million people a year. But that plan faces some serious snags, according to UC Davis researchers who are suggesting an alternative strategy. A Blueprint For US National Ocean Policy For The 21st Century 
WASHINGTON DC - Apr 21, 2004Calling on Congress and President Bush to establish a new national ocean policy that balances use with sustainability, is based on sound science and educational excellence, and moves toward an ecosystem-based management approach is the centerpiece of the Preliminary Report released today by the U.S. Commission on Ocean Policy. Moss Landing Researchers Reveal Iron As Key To Climate Change 
Moss Landing - Apr 20, 2004A remarkable expedition to the waters of Antarctica reveals that iron supply to the Southern Ocean may have controlled Earth's climate during past ice ages. A multi-institutional group of scientists, led by Dr. Kenneth Coale of Moss Landing Marine Laboratories (MLML) and Dr. Ken Johnson of the Monterey Bay Aquarium Research Institute (MBARI), fertilized two key areas of the Southern Ocean with trace amounts of iron. Ocean Fertilization With Iron To Foster Carbon Dioxide Eating Plankton
Falmouth MA - Apr 20, 2004Dumping iron in the ocean is known to spur the growth of plankton that remove carbon dioxide, a greenhouse gas, from the atmosphere, but a new study indicates iron fertilization may not be the quick fix to climate problems that some had hoped. No-Till Farming Offers A Quick Fix To Host Of Global Problems 
Columbus OH - Apr 20, 2004Increase no-till farming practices across the planet or face serious climate, soil quality and food production problems in the next 20 to 50 years. That warning from scientists appeared in the journal Science this week. UC Riverside Researchers Improve Drought Tolerance in Plants 
Riverside CA - Apr 20, 2004Researchers from University of California at Riverside have reported the development of technology that increases crop drought tolerance by decreasing the amount of an enzyme that is responsible for recycling vitamin C. Satellites Record Weakening North Atlantic Current 
Greenbelt - Apr 16, 2004A North Atlantic Ocean circulation system weakened considerably in the late 1990s, compared to the 1970s and 1980s, according to a NASA study. Sirpa Hakkinen, lead author and researcher at NASA's Goddard Space Flight Center, Greenbelt, Md. And co-author Peter Rhines, an oceanographer at the University of Washington, Seattle, believe slowing of this ocean current is an indication of dramatic changes in the North Atlantic Ocean climate. |
UCLA Geophysicist Warns 6.4 Quake To Hit LA By Sept 5'
Los Angeles - Apr 15, 2004A US geophysicist has set the scientific world ablaze by claiming to have cracked a holy grail: accurate earthquake prediction, and warning that a big one will hit southern California by Sept 5. Decoding A Sulfate-Breathing Bug 
Rockville MD - Apr 14, 2004Paving the way for better methods to protect pipelines and remediate metallic pollutants, scientists have sequenced the genome of a sulfate-breathing bacterium that can damage oil and natural gas pipelines and corrode oilfield equipment. Siberia, The Big Bang of Life? 
Gainesville FL - Apr 13, 2004Trilobites, the primitive shelled creatures considered by many to be among the first animals to appear in the fossil record, may have originated in a place known today largely for its barren lifelessness: Siberia. New Method Determining Age Of Neolithic Artifacts 
Irvine CA - Apr 13, 2004A UC Irvine archaeological scientist has created a new method for determining the approximate age of many artifacts between 50,000 to 100,000 years old � a period for which other dating methods are less effective. Better Techniques Needed To Predict Earthquake Hazards 
San Francisco - Apr 13, 2004Current methods for estimating the ground-shaking effects of major earthquakes could underestimate their severity and lead to inadequate seismic protection of new and existing buildings, according to a pioneering study of earthquake hazards at three University of California campuses � Riverside (UCR), San Diego (UCSD), and Santa Barbara (UCSB). Earth Impact Effects Program 
Tucson AZ - Apr 08, 2004Next time an asteroid or comet is on a collision course with Earth you can go to a web site to find out if you have time to finish lunch or need to jump in the car and DRIVE. Possible Answer To Earth's Magnetic Field Reversal 
Arlington VA - Apr 08, 2004Earth's magnetic field reverses every few thousand years at low latitudes and every 10,000 years at high latitudes, a geologist funded by the National Science Foundation (NSF) has concluded. Brad Clement of Florida International University published his findings in this week's issue of the journal Nature. The results are a major step forward in scientists' understanding of how Earth's magnetic field works. |
