Sustainable farm practices improve Third World food production

Crop yields on farms in developing countries that used sustainable agriculture rose nearly 80 percent in four years, according to a study scheduled for publication in the Feb. 15 issue of the American Chemical Society journal . The study, the largest of its kind to date -- 286 farm projects in 57 countries -- concludes that sustainable agriculture p...

For the first time: Longevity modulated without disrupting life-sustaining function

Within a hormone-triggered cascade of molecular signals that plays a crucial for a wide range of physiological functions, researchers for the very first time have identified a protein that functions specifically to extend lifespan and youthfulness -- without disrupting fertility, immunity or the organism's response to stress. "In past experiments, meddling with this versatile pathway to ex...

Biodiversity key to sustainable biofuel according to University of Minn. researcher's findings

Ecosystems containing many different plant species are not only more productive, they are also better able to withstand and recover from climate extremes, pests and disease over long periods of time. These findings, published in the June 1 issue of Nature, are the culmination of 12 years of experiments conducted by David Tilman, Regents Professor of Ecology at the University of Minnesota,...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) have found a viral target that opens the door for the development of drugs to destroy tumors caused by Epstein-Barr virus (EBV). The finding, published in the Sept. 4 Proceedings of the National Academy of Sciences Online, identifies the activity of a critical segment of a viral protein required to sust...

NIDA study identifies genes that might help some people abstain from smoking

Scientists supported by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, have for the first time identified genes that might increase a person’s ability to abstain from smoking. The breakthrough research was conducted by Dr. George Uhl at NIDA’s Intramural Research Program and a team led by Dr. Jed Rose at the Center for Nicotine and Smoking Cessation Resear...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

The study, available in today’s online edition of Current Biology, confirms captive chimpanzees have the capacity to sustain...

New study finds genetically engineered crops could play a role in sustainable agriculture

Genetically modified (GM) crops may contribute to increased productivity in sustainable agriculture, according to a groundbreaking study published in the June 8 issue of the journal Science. The study analyzes, for the first time, environmental impact data from field experiments all over the world, involving corn and cotton plants with a Bt gene inserted for its insecticidal properties. The...
