U.S. government scientists have come up with a way to keep apples from turning brown for up to five weeks after they've been sliced or peeled. The new technique, which uses natural products and doesn't require special packaging, could eventually have a major impact on the marketability of fresh-cut fruit.
New evidence suggests that the chemical which prompts a hangover after a night of heavy drinking may also cause cancer, according to an international team of scientists.
Examining sediment cores from New York's Central Park Lake dating back 100 years, a group of scientists conclude that incineration of solid waste, rather than leaded gasoline, has been the dominant source of atmospheric lead to the New York City metropolitan area, and possibly many other urban areas during the 20th century.
The chemicals that give tart cherries their red color may relieve pain better than aspirin and may provide antioxidant protection comparable to commercially available supplements like vitamin E, according to Michigan State University researchers.
Researchers have developed a new protease inhibitor effective against mutating strains of the human AIDS virus that are resistant to current drugs, according to a just-released report in the peer-reviewed Journal of the American Chemical Society. The same chemical may also become the first treatment for feline AIDS, a significant threat to the world cat population.
A new, more effective method for destroying potentially deadly toxins called microcystins that can be found in drinking water has been announced by researchers in Scotland. Microcystins are produced by blue-green algae, which can grow in reservoirs, lakes and other bodies of water that are used for municipal drinking water.
A new bioreactor system that serves up pollutants to "hungry" bacteria promises to clean up "unprecedented" levels of toxic organic chemicals classified as "priority pollutants" by the U.S. Environmental Protection Agency, according to Canadian researchers. The scientists envision its use in cleaning up contaminated sites and to get rid of old chemical supplies.
Arsenic concentrations that exceed current recommended federal levels for drinking water are 10 times more likely to be found in domestic wells than in municipal water sources in New Hampshire, according to a study by researchers at Dartmouth College.
Researchers say they have confirmed, for the first time, that blue-green algae taken as a nutritional supplement can significantly lower cholesterol in animals.
A new protein-like polymer that supports the growth of endothelial cells and could be used for blood vessel replacement has been designed by researchers at the California Institute of Technology
