KNOXVILLE -- Mercury pollution is a persistent problem in the environment. Human activity has lead to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges for the heavy metal.
COLUMBIA, Mo. -- With more than 2 million cows on 68,000 farms, Missouri is the third-largest beef producer in the nation. Due to rising feed prices, farmers are struggling to provide feed for the cows that contribute more than $1 billion to Missouri's economy.
The levels of the components in breast milk change every 24 hours in response to the needs of the baby. A new study published in the journal Nutritional Neuroscience shows, for example, how this milk could help newborn babies to sleep.
St. Louis, MO, October 1, 2009 -- Both household food insecurity (HFInsec) and childhood overweight are significant problems in the United States. Paradoxically, being food-insecure may be an underlying contributor to being overweight.
Cheaters may prosper in the short term, but over time they seem doomed to fail, at least in the microscopic world of amoebas where natural selection favors the noble.
When society jumps on a bandwagon, even for a good cause, there may be unintended consequences. The unintended consequence of crop-based biofuels may be the loss of wildlife habitat, particularly that of the birds who call this country's grasslands home, say researchers
from Michigan Technological University and The Nature Conservancy.
A new study of microscopic marine microbes, called phytoplankton, by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of South Carolina has solved a ten-year-old mystery about the source of an essential nutrient in the ocean.
Although arsenic (As) occurs ubiquitously in the environment and has been used since its isolation in 1250 A.D in various fields such as medicine, metallurgy, agriculture and electronics, it is undoubtedly best known for its toxicity to both plants and animals. The toxic effects of arsenic in humans range from skin lesions to cancer of the brain, liver, kidney and stomach.
WASHINGTON -- Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council.
Exposure to light and possibly photosynthesis itself could be helping disease-causing bacteria to be internalized by lettuce leaves, making them impervious to washing, according to research published in the October issue of the journal Applied and Environmental Microbiology.
Monday, September 27, 2009, Rockville, Md. -- Counterfeit and adulterated food and drugs and advances in measurement science used to detect them emerged as key themes of the Annual Scientific Meeting (ASM) hosted by the U.S. Pharmacopeial (USP) Convention. Held in Toronto, Canada, more than 300 people from 26 countries attended, making this a truly multinational event.
DURHAM, N.C. -- Spotted hyenas may not be smarter than chimpanzees, but a new study shows that they outperform the primates on cooperative problem-solving tests.
"To put it simply, there is not enough rice to feed the world," says Dr. Robert Zeigler, director general of the International Rice Research Institute (IRRI).
Physicists are continually reaching new lows as they reduce the temperatures of samples in their laboratories. But even nano-kelvins are not low enough to overcome the entropy (a measure of the disorder in a system) that stands between them and the discovery of exotic states of ultra-cold matter.
