Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats.

What happens in the brain of a compulsive drug user? Neurobiologists have discovered that the brain circuit connecting the decision-making region to the reward system is stronger in compulsive animals. The researchers also found that by decreasing the activity of this circuit, compulsive mice were able to regain control and that conversely, by stimulating the connection a mouse that initially remained in control became addicted.

Scientists have determined the conditions under which it becomes easier for sac to pass through biological membranes and potentially deliver molecules attached to these them at specific locations.

Biomedical engineers have determined which patients would benefit the most from a commonly used drug treatment.

A study sheds new light on how the hallmarks of Alzheimer's disease -- amyloid-beta plaques and neurofibrillary tangles containing the protein tau -- produce their damaging effects in the brain.

Declining life expectancies in the US include Gen X and Y Americans, in addition to the older Baby Boomers. But the causes of premature mortality vary by race, gender and ethnicity, according to a new study. The researchers examined data from the Centers for Disease Control and Prevention Mortality Multiple Cause Files for the years 1990-2016.
