For the first time, scientists and engineers have identified a critical cancer-causing component in the virus that causes Kaposi's sarcoma, the most common cancer among HIV-infected people. The discovery lays the foundation for developing drugs that prevent Kaposi's sarcoma and other related...

When children and child-care providers sit around a table together at mealtime, passing bowls and serving themselves, children learn to recognize when they are full better than they do when food is pre-plated for them, reports a new University of Illinois study of feeding practices of two- to...

Duke scientists have taken aim at what may be the Achilles' heel of the HIV virus. Combining expertise in biochemistry, immunology and advanced computation, researchers at Duke University have determined the structure of a key part of the HIV envelope protein, the gp41 membrane proximal external...

New research shows that humans and other primates burn 50 percent fewer calories each day than other mammals. The study, published Jan. 13 in the Proceedings of the National Academy of Sciences, suggests that these remarkably slow metabolisms explain why humans and other primates grow up so slowly...

In a paper published in this week's Online Early Edition of the Proceedings of the National Academy of Sciences, researchers from the University of California, San Diego School of Medicine identify a key gene receptor and signaling pathway essential to maintaining human embryonic stem cells in an...

Scientists from the Florida campus of the Scripps Research Institute have described a pair of drug candidates that advance the search for new treatments for pain, addiction and other disorders. The two new drug scaffolds offer researchers novel tools that act on a demonstrated therapeutic target,...

Four years after the January 2010 earthquake, 145,000 people still remain homeless in Haiti. A cheap and simple technology to repair earthquake damaged buildings -- developed at the University of Sheffield, UK, -- could help to reduce these delays by quickly making buildings safe and habitable.

Ohio State University Wexner Medical Center researchers have developed an at-home test that can help doctors spot early symptoms of cognitive issues in their patients, like Alzheimer's disease. The test is cheap, self-administered, and a new study shows, can be just as effective as other costlier...

School drug testing does not deter teenagers from smoking marijuana, but creating a "positive school climate" just might, according to research reported in the January issue of the Journal of Studies on Alcohol and Drugs. Fuente : http://www.eurekalert.org/pub_releases/2014-01/jos...

Older adults who received as few as 10 sessions of mental (cognitive) training showed improvements in reasoning ability and speed-of-processing when compared with untrained controls participants as long as 10 years after the intervention. These gains were even greater for those who got additional...

Patients with head and neck cancer who are treated with an advanced form of radiation therapy may experience fewer side effects and be less likely to die from their disease than patients who receive standard radiation therapy. That is the finding of an analysis published early online in Cancer, a...

White parents reported higher use of age-appropriate car seats for one- to seven-year-old children than non-white parents, according to a new University of Michigan study. The race of the parents is a significant predictor of whether a child is placed in the right safety seat for his or her age....

Teenage boys who think they're too skinny when they are actually a healthy weight are at greater risk of being depressed as teens and as adults when compared to other boys, even those who think they are too heavy, according to findings published by the American Psychological Association.
