As Andean glacier retreats, tiny life forms swiftly move in, CU-Boulder study shows
A University of Colorado at Boulder team working at 16,400 feet in the Peruvian Andes has discovered how barren soils uncovered by retreating glacier ice can swiftly establish a thriving community of microbes, setting the table for lichens, mosses and alpine plants. view more (2008-09-09)
Structure of enzyme against chemical warfare agents determined
The enzyme DFPase from the squid Loligo vulgaris, is able to rapidly and efficiently detoxify chemical warfare agents such as Sarin, which was used in the Tokyo subway attacks in 1995. view more (2009-01-29)
Unlocking the frozen secrets of comet Wild 2
Eleven months ago, NASA's Stardust mission touched down in the Utah desert with the first solid comet samples ever retrieved from space. Since then, nearly 200 scientists from around the globe have studied the minuscule grains, looking for clues to the physical and chemical history of our solar system. view more (2006-12-20)
Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric... view more...

New oxidation methods streamline synthesis of important compounds
One of the fundamental challenges facing organic synthesis in the 21st century is the need to significantly increase the efficiency with which carbon frameworks can be constructed and functionalized. view more (2007-08-03)
Light activated anticancer drug targeted to DNA using cisplatin like sub-units
One of the most effective chemotherapy drugs against cancer is cisplatin because it attaches to cancer DNA and disrupts repair. view more (2006-03-27)
The Role Of Phytochromes In Bacteria Revealed
A research team jointly involving the IRD, the CEA and the CNRS has very recently found phytochromes in a strain of nitrogen-fixing bacterium, Bradyrhizobium (1), symbiont on certain tropical leguminous plants (the Aeschynomene). Techniques of molecular biology, biophysics and biochemistry revealed that the newly-discovered phytochrome has an... view more... (2002-05-13)
Air pollution from ships - a serious threat
Emissions from ships may bring as much nitrogen oxide to the atmosphere as the total amount of emissions coming from the USA. International shipping along the Norwegian coast and in the Northern Atlantic Ocean contributes largely to the formation of ground-level ozone and acidification of the shores. Air pollution from ships may be twice as bad as... view more... (2004-03-30)
Numerical simulations of nutrient transport changes in Honghu Lake Basin
The research by Gui Feng & Yu Ge showed the relative role of natural, climate-induced changes versus human-related activities in nutrient transportation changed over time. view more (2008-08-20)
Abertay researchers in clover to unearth destructive bug
Scots scientists are playing a key role in a major new research effort which could save Britain's farmers millions of pounds a year through reductions in fertiliser and pesticide use. Biotechnology experts at the University of Abertay Dundee, in partnership with two organisations in England, have been awarded £471,000 by the BBSRC... view more... (2002-04-04)
Researchers put the bite on mosquitoes
Few things sting like a mosquito's bite--especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well. view more (2008-01-17)
Sunlight turns carbon dioxide to methane
Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers. view more (2009-03-05)
Isotope analysis reveals foraging area dichotomy for Atlantic leatherback turtles
The beaches of French Guiana constitute a major reproduction site for leatherback turtles. This sea turtle, although a protected species, is threatened by human activity: it ingests plastics, get accidentally caught in fishing nets, sees its egg-laying sites destroyed and its adults hunted illegally for their meat and their eggs. view more (2008-03-26)
Winds trigger increases in ozone destroying gases in upper stratosphere
A surprising new University of Colorado at Boulder study indicates winds circling high above the far Northern Hemisphere have a much greater impact on upper stratospheric ozone levels than scientists had thought. view more (2006-09-29)
Insects take a bigger bite out of plants in a higher CO2 world
Atmospheric carbon dioxide levels are rising at an alarming rate, and new research indicates that soybean plant defenses go down as CO2 goes up. Elevated CO2 impairs a key component of the plant's defenses against leaf-eating insects, according to the report. view more (2008-03-25)
First buoy to monitor ocean acidification launched
The first buoy to monitor ocean acidification has been launched in the Gulf of Alaska. Attached to the 10-foot-diameter buoy are sensors to measure climate indicators. view more (2007-06-13)
Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity. view more (2008-04-25)
Pesticides Persist in Ground Water
Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. view more (2008-07-02)
Economical and cleaner cars with lean-burn catalytic converter
Dutch researcher Karen Scholz has taken a careful look at the properties of a new type of catalytic converter found in cars. view more (2007-07-13)
Extreme makeover chemistry style
In revisiting a chemical reaction that's been in the literature for several decades and adding a new wrinkle of their own, researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. view more (2009-06-17)
