CHAPEL HILL "“ A new tuberculosis vaccine successfully tested at the University of North Carolina at Chapel Hill is easier to administer and store and just as effective as one commonly used worldwide. Scientists at the UNC School of Pharmacy led by Tony Hickey, Ph.D., vetted a dry powder vaccine provided by Harvard University that is administered using an inhaler. The results of the vaccine test are being published this week in the Proceedings of the National Academy of Sciences. "It is...

Competing against older brothers and sisters can be tough work, as any youngest child will tell you.But new research from a biologist at the University of North Carolina at Chapel Hill shows that when it comes to some birds, you should reserve any underdog sympathies for the first born "“ or rather, first laid "“ siblings as well.The finding, published in the March 12 issue of PLoS ONE, runs somewhat counter to common wisdom, which holds that baby birds that are laid before their...

Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. But as concern about drug-resistant bacteria grows, one novel approach under way at the University of North Carolina at Chapel Hill seeks to thwart the bug without a drug by taking a cue from nature. Mark Schoenfisch and his lab of analytical chemists at UNC have created nano-scale scaffolds made of silica and loaded with nitric oxide (NO) "“ an important...

By Sabia, Joseph J Controlling for a wide set of individual- and family-level observables available in the National Longitudinal Study of Adolescent Health, ordinary least squares (OLS) estimates show that sexually active adolescents have grade point averages that are approximately 0.2 points lower than virgins. However, when information on the timing of intercourse decisions is exploited and individual fixed effects are included, the negative effect of sexual intercourse disappears for...

By Karen Garloch, The Charlotte Observer, N.C. Jul. 1--Along Interstate 85, billboards boast of NorthEast Medical Center's new CyberKnife, a robot that performs "knifeless cancer surgery" with "precision accuracy." Ads call it "the world's most accurate robotic radiosurgery device." Despite the hype, the $3.7 million CyberKnife is just one of a number of technologies that deliver high-energy radiation with pinpoint accuracy to shrink or obliterate tumors with fewer treatments for patients...

CHAPEL HILL -- Books offering advice to parents about teens are less likely to contain injury prevention messages than those that give advice on parenting smaller children, according to a new University of North Carolina at Chapel Hill study. Notably absent from most such books were discussions about preventing automobile accidents among adolescents. The UNC Injury Prevention Research Center investigation, which appears in the November issue of the journal Pediatrics, involved reviewing the...

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...
