Researchers have developed a method to treat bacterial infections which could result in better wound care.

Researchers using sophisticated MRI technology have found that higher levels of body fat are associated with differences in the brain's form and structure, including smaller volumes of gray matter, according to a new stu...

Researchers have studied the regenerative capacity of zebrafish brain in single cell resolution with the aim of developing novel strategies against Alzheimer's.

Scientists have invented a new technology that could lead to the development of a new generation of smart surgical glues and dressings for chronic wounds. The new method involves re-engineering the membranes of stem cell...

Mice have a strong preference to nest away from their own waste, new research has found. The study showed that mice who were housed in a system of three interconnected cages used separate cages for nesting and eliminatin...

A decade ago, the U.S. federal government overhauled nutrition standards for food packages in its primary food assistance program for young mothers and their children. The change reduced obesity risks for 4-year-olds, ac...
