High screen use increases body fat in teenagers

Too much television, video games and Internet can increase body fat in teens. A five-year study from the University of Montreal and the Sainte-Justine Hospital Research Center, published in the American Journal of Epidemiology, has found teenagers have four different patterns of screen use: increasers, decreasers, consistently high and consistently low users.

Study suggests older people may not benefit from new tuberculosis vaccines

Elderly people might not benefit from some of the tuberculosis vaccines currently in development, recent research suggests.Some vaccines under study are designed to activate a specific molecule that is an early participant in the immune response against TB in young people. But a recent Ohio State University study suggests that in older people, this molecule remains relatively inactive, even in the face of TB infection.

Biomarkers may help predict children at high risk of developing type 2 diabetes

Children who have a high risk of developing type 2 diabetes might be identified earlier by way of tell-tale genetic indicators known as biomarkers. Some of those new biomarkers might be pinpointed in research led by Nancy F. Butte and funded by the U.S. Department of Agriculture (USDA) and the U.S. Department of Health and Human Service's National Institutes of Health.

BRCA1 gene mutation increases breast cancer risk: Research

Individuals with disrupting mutations in the BRCA1 gene are known to be at substantially increased risk of breast cancer throughout their lives. Now, discoveries from an international research team led by Mayo Clinic researchers show that some of those persons may possess additional genetic variants that modify their risk. These new findings enhancing individualized medicine appear in the current Nature Genetics.
