The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality. Researchers from the Center of Plant Genomics and Biotechnology at the Technical University of Madrid (UPM) and the Advanced Photon Source (APS) at the U.S. Department of...

Lawrence LeBlond for redOrbit.com - Your Universe Online Many foods we eat may not be so good for us. But many others provide crucial benefits for healthy living. It may come as no surprise that one food, the beet, or more appropriately, beetroot juice, may help provide some of those crucial benefits we see in a wide array of other foods. Of course we all know we should always eat more fruits and vegetables, but how often have you heard your mother say, ℠Make sure you drink your...

Atmospheric Nitrogen Levels Have Remained Stable Over Past 500 Years Despite Widespread Emissions
2013-03-21 16:16:59

Brett Smith for redOrbit.com - Your Universe Online Despite widespread use of fertilizers and nitrogen emissions by industrial processes, the amount of atmospheric nitrogen has remained consistent over the past 500 years, according to a new study in Nature. "People have been really interested in nitrogen in current times because it's a major pollutant," said study co-author Kendra McLauchlan, an assistant professor of geography at Kansas State University. "Humans are producing a lot...

2013-03-20 09:17:36

USDA Forest Service - Pacific Northwest Research Station Drawing on 500-plus-years of data, study highlights value of long-term stream monitoring For the first time, a study has compared water quality trends in forested streams across the country that are largely undisturbed by land use or land cover changes. The study, which draws on decades' worth of data from reference streams in six U.S. states and Puerto Rico, underscores the value of long-term data in understanding the patterns...

Transfusion of donated blood more than three weeks old results in impaired blood vessel function, a new study of hospital patients shows. Blood banks now consider six weeks to be the maximum permitted storage time of blood for use in transfusion, but recent studies have suggested transfusing blood stored for more than a few weeks has adverse effects in patients undergoing cardiac surgery or critical care. The new finding suggests a mechanism explaining why older blood might be...

National Radio Astronomy Observatory [ Watch the Video Answering Questions Of Where Prebiotic Molecules Form ] Using new technology at the telescope and in laboratories, researchers have discovered an important pair of prebiotic molecules in interstellar space. The discoveries indicate that some basic chemicals that are key steps on the way to life may have formed on dusty ice grains floating between the stars. The scientists used the National Science Foundation's Green Bank...
