Organic corn: Increasing rotation complexity increases yields
While demand for organic meat and milk is increasing by about 20% per year in the United States, almost all organic grain and forage to support these industries in the mid-Atlantic region is imported from other regions. To meet this demand locally, area farmers need information on expected crop yields and effective management options. view more (2008-05-29)
Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among the world's scientists for over ten years. John... view more... (2004-03-18)
Diamonds may be the ultimate MRI probe, say Quantum physicists
Diamonds, it has long been said, are a girl's best friend. But a research team including a physicist from the National Institute of Standards and Technology (NIST) has recently found that the gems might turn out to be a patient's best friend as well. view more (2009-09-23)
NOAA and Louisiana scientists predict largest Gulf of Mexico 'dead zone' on record
NOAA-supported scientists from the Louisiana Universities Marine Consortium and Louisiana State University are forecasting that the "dead zone" off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be the largest on record. view more (2008-07-16)
When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. view more (2008-10-17)
UCR chemists prepare molecules that accelerate chemical reactions for manufacturing drugs
Chemists at the University of California, Riverside have synthesized a new class of carbenes - molecules that have unusual carbon atoms - that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs. view more (2005-08-22)
Ozone, nitrogen change the way rising CO2 affects Earth's water
Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. view more (2009-07-10)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Alternative farming cleans up water
Although the addition of nutrients to soil helps to maximize crop production, fertilizer can leach nutrients, polluting the water supply. view more (2007-07-20)
Nile Delta fishery grows dramatically thanks to run-off of sewage, fertilizers
While many of the world's fisheries are in serious decline, the coastal Mediterranean fishery off the Nile Delta has expanded dramatically since the 1980s. view more (2009-01-20)
International team of scientists discover clue to delay of life on Earth
Scientists from around the world have reconstructed changes in Earth's ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. view more (2008-03-27)
Is Your Drinking Water Safe?
Lake Bloomington is a major source of drinking water for residents of Bloomington, IL, and has a history of nitrate concentrations that exceed safe levels. Because Lake Bloomington has a record of elevated nitrate levels, local residents are concerned over their drinking water quality. view more (2008-02-29)
Pitt professor says harmful byproducts of fossil fuels could be higher in urban areas
Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize. view more (2007-10-23)
Rotting leaf litter study could lead to more accurate climate models
Over the past decade, in numerous field sites throughout the world, mesh bags of leaf and root litter sat exposed to the elements, day and night, throughout the four seasons, gradually rotting away. view more (2007-01-19)
Princeton-led team finds secret ingredient for the health of tropical rainforests
A team of researchers led by Princeton University scientists has found for the first time that tropical rainforests, a vital part of the Earth's ecosystem, rely on the rare trace element molybdenum to capture the nitrogen fertilizer needed to support their wildly productive growth. view more (2008-12-10)
Underwater Microscope Finds Biological Treasures in the Subtropical Ocean
Scientists towing an underwater digital microscope across the Atlantic have found possible missing links to the global nitrogen cycle, which in turn is linked to ocean productivity. view more (2006-06-27)
Italian study finds traffic pollution affects male fertility
A study by Italian researchers of motorway tollgate attendants has demonstrated that traffic pollution damages the quality of sperm in young and middle-aged men. In research published today (Wednesday 30 April) in Europe's leading reproductive medicine journal Human Reproduction[1] the research team from the University of Naples say their work... view more...

Earth's biogeochemical cycles, once in concert, falling out of sync
What do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles that involve all three. view more (2009-08-04)
"Acid rain" and forest mass: another perspective
A few years ago the study of the effects of atmospheric deposition on forest ecosystems reached beyond the scientific sphere and the term "acid rain" was coined. view more (2005-10-14)
Amazon powers tropical ocean's carbon sink
Nutrients from the Amazon River spread well beyond the continental shelf and drive carbon capture in the deep ocean, according to the authors of a multi-year study. view more (2008-07-22)
