CHAPEL HILL "“ Through efforts to limit exposure to environmental irritants, health workers and municipalities can cut illness generally among inner-city children with asthma and also the number of clinic visits for those young patients by at least 19 percent, a new study concludes. The cost can be as low as $1,469 per affected family. Last year, researchers reported in the New England Journal of Medicine that an intervention designed to reduce exposures of children with asthma to...

CHAPEL HILL "“ An enzyme inside a bacterium that grows in the soil of potato fields can -- in a split second -- break down residues of a common powerful pesticide used for killing worms on potatoes, researchers have found. That may be expensive for farmers but lucky for the environment because University of North Carolina at Chapel Hill scientists have now discovered that if that particular enzyme weren't there, it would take 10,000 years for just half of the widely used pesticide to...

CHAPEL HILL -- No good evidence exists that fossilized structures found in China and which some paleontologists claim are the earliest known rudimentary feathers were really feathers at all, a renowned ornithologist says. Instead, the fossilized patterns appear to be bits of decomposed skin and supporting tissues that just happen to resemble feathers to a modest degree. Led by Dr. Alan Feduccia of the University of North Carolina at Chapel Hill, a team of scientists says that as a result of...

CHAPEL HILL -- In the immediate wake of Hurricane Katrina, scientists and research centers from across the country came together to generate information on the contaminated floodwaters and offer it to hazardous materials experts and public health officials. In a matter of hours, the University of North Carolina at Chapel Hill's Marine Sciences Program and Renaissance Computing Institute (RENCI), together with the National Center for Supercomputing Applications (NCSA), played a key role in...

CHAPEL HILL -- In the wake of Hurricane Katrina -- probably the greatest natural disaster in U.S. history -- a leading ecologist says that one of the best things that could happen to New Orleans and the rest of southern Louisiana and Mississippi would be more rain. "People might think I'm kidding, but I'm not," said Dr. Seth R. Reice, associate professor of biology at the University of North Carolina at Chapel Hill's College of Arts and Sciences. "The floodwater still covering much of...

CHAPEL HILL "“ Fears that chemical byproducts resulting from purifying drinking water with chlorine boost the chances that pregnant women will miscarry were not supported by the results of a major new study. If such threats exist at all, which is uncertain, they likely are modest, it concludes. The national study, directed by University of North Carolina at Chapel Hill scientists, contrasts with earlier, less detailed work done in Northern California and published in 1998. That research...

CHAPEL HILL - Local health department directors across North Carolina are confused about state laws covering whether their facilities can be made smoke-free, but still strongly support such policies, according to a new University of North Carolina at Chapel Hill study. The UNC schools of medicine and public health research showed that a majority of the directors were unsure or did not think they could enact tobacco-free policies on health department grounds. In response to the confusion,...

CHAPEL HILL - Experimenting with Arabidopsis, a fast-growing cousin of the humble mustard plant, scientists at the University of North Carolina at Chapel Hill got a big surprise while investigating how plants respond to attacks from disease organisms such as bacteria and viruses. "Contrary to what we thought we'd find, our experiments showed that at least three different proteins work in concert with one another in tug-of war or teeter totter-fashion to keep plant defenses in a state of...

CHAPEL HILL "“ University of North Carolina at Chapel Hill chemists have developed what they believe is a breakthrough method of creating the world's tiniest manufactured particles for delivering drugs and other organic materials into the human body. Adapting technology pioneered by the electronics industry in fabricating transistors, the team has figured out for the first time how to create particles for carrying genetic material, pharmaceuticals and other compounds of unprecedented...

CHAPEL HILL - The ages at which workers are exposed to low doses of ionizing radiation apparently make a difference in whether they will develop cancer, according to a new University of North Carolina at Chapel Hill study. UNC scientists investigated deaths among workers at the U.S. Department of Energy's Hanford Site in Richland, Wash. The Hanford Site produced plutonium for atomic weapons, including the first plutonium bombs dropped during World War II. Researchers say the largest cancer...
