Researchers have used a drug to achieve normal levels of blood sugar in animals genetically engineered to have abnormally high insulin levels. If this approach succeeds in humans, it could become an innovative medicine for children with congenital hyperinsulinism, a rare but potentially devastating genetic disease in which insulin levels become dangerously high. There is currently no effective medical treatment for children with the most common type of congenital hyperinsulinism.

Researchers at Yale School of Medicine have found the brain's appetite center uses fat for fuel by involving oxygen free radicals -- molecules associated with aging and neurodegeneration. The findings suggest that antioxidants could play a role in weight control.

One of the major reasons that treatment for HIV/AIDS often doesn't work as well as it should is resistance to the drugs involved. Now, scientists have determined how mutations hidden in previously ignored parts of the HIV genome play an important role in the development of drug resistance in AIDS patients.

What's causing some university students to pack on the pounds? University of Alberta researchers say the culprit could be television commercials. Researchers discovered students who reported medium or high television viewership snacked more frequently while watching TV and recognized more advertising than students who were considered low TV viewers.

Researchers have designed equipment to provide high resolution images of the heart at a critical stage of testing that have previously been difficult to obtain using standard testing procedures. Superior images of the heart are obtained with a test lasting less than one hour.

Men who marry a child's mother parent just as well, if not better than biological fathers. A new study examined differences in the parenting practices of four groups of fathers according to whether they were biologically related to a child and whether they were married to the child's mother.

Among patients receiving dialysis for chronic kidney disease, high levels of alkaline phosphatase -- a routinely measured laboratory marker of bone disease -- may signal an increased risk of death, reports a new study.

Researchers have identified the brain mechanism that switches off traumatic feelings associated with bad memories, a finding that could lead to the development of drugs to treat panic disorders.
