Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches hav
Drinking. Drugs. Caving into peer pressure. When parents expect their teenagers to conform to negative stereotypes, those teens are in fact more likely to do so, according to new research by Christy Buchanan, professor of psychology at Wake Forest University.
CHAPEL HILL -- For decades, scientists have thought the faulty neural wiring that predisposes individuals to behavioral disorders like autism and psychiatric diseases like schizophrenia must occur during development. Even so, no one has ever shown that a risk gene for the disease actually disrupts brain development.
MADISON, WI, OCTOBER 12, 2009 -- Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. "urban grasslands" are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S.
CHAPEL HILL -- Children with functional abdominal pain who used audio recordings of guided imagery at home in addition to standard medical treatment were almost three times as likely to improve their pain problem, compared to children who received standard treatment alone.
DURHAM, N.C. -- A strain of yeast that thrives on turning sugar cane into ethanol for biofuel has had its genome completely sequenced by researchers at Duke University Medical Center.
Colorectal cancer is a leading cause of cancer-related deaths in the United States, leading to over 50,000 fatalities every year. But it can be prevented with early screening using a procedure called a colonoscopy.
HIV prevalence among African Americans is ten times greater than the prevalence among whites. This racial disparity in HIV prevalence has persisted in the face of both governmental and private actions, involving many billions of dollars, to combat HIV.
CHAPEL HILL -- In populating the growing brain, neural stem cells must strike a delicate balance between two key processes -- proliferation, in which the cells multiply to provide plenty of starting materials -- and differentiation, in which those materials evolve into functioning neurons.
CHAPEL HILL, N.C. -- Treating pregnant women for mild gestational diabetes resulted in fewer cesarean sections and other serious birthing problems associated with larger than average babies, according to a study conducted in part at the University of North Carolina at Chapel Hill.
CHAPEL HILL -- A new study shows that parents are more likely to understand a body mass index (BMI) chart if it's color-coded, like a traffic light, than the standard charts currently in use.
A new longitudinal study that looks at how low-income parents discipline their young children has found that spanking 1-year-olds leads to more aggressive behaviors and less sophisticated cognitive development in the next two years. Verbal punishment is not associated with such effects, especially when it is accompanied by emotional support from moms.
CHAPEL HILL -- Researchers at the University of North Carolina at Chapel Hill School of Medicine and the College of Arts & Sciences have identified a new biological process that spurs the growth of new blood vessels.
CHAPEL HILL, N.C. -- Researchers at the University of North Carolina at Chapel Hill have discovered a genetic risk factor for severe liver disease in people with cystic fibrosis.
PHILADELPHIA -- Chronic periodontitis, a form of gum disease, is an independent risk factor for head and neck squamous cell carcinoma. This suggests the need for increased efforts to prevent and treat periodontitis as a possible means to reduce the risk of this form of cancer.
