New findings show that, on top of its benefits for metabolism, mood, and general health, exercise also improves brain function. In recent studies, researchers learned that obese and overweight individuals are prone to in...

How does the brain process rewards? Researchers are investigating how the brain responds differently to two commonly ingested rewards -- food and alcohol -- to understand how they alter neural activity and behavior.

Neuroscience researchers have identified a surprising new role for the 'hunger hormone' ghrelin. Ghrelin has previously been recognized for its unique role in sending hunger signals from the gut to the brain, but new fin...

Recent research suggests that the psychological consequences of being in a disadvantaged position in society may stimulate appetite and increase eating regardless of one's ability to access healthier foods.

Extremely premature infants who fail to grow as expected have delayed development of their microbiome, or communities of bacteria and other micro-organisms living in the gut, according to a new study.

A bioengineering group is bringing the worlds of computational modeling and experimentation closer together by developing a methodology to help analyze the wealth of imaging data provided by advancements in imaging tools...

Mucus (shown in pink) is secreted by a cell in the stomach. (Credit: The Path to Digestion Is Paved with Repair. Underwood J, PLoS Biology Vol. 4/9/2006, e307. doi:10.1371/journal.pbio.0040307) We know it best as a strin...

In a new study, researchers have shown the key role that a protein called Ran plays in the mobility of ovarian cancer cells. They demonstrated these cells cannot migrate from cancerous sites without the help of Ran.

Research results on drug-gene interactions are much less likely to be replicated if they are performed by hierarchical communities or close-knit groups of frequent collaborators who use similar methods, instead of indepe...

A worldwide coalition of researchers and clinicians has agreed that light therapy is among the most effective interventions for the prevention of oral mucositis, painful ulcers in the mouth resulting from cancer therapy.

Atypical eating behaviors may be a sign a child should be screened for autism, according to researchers who found that atypical eating behaviors were present in 70 percent of children with autism, which is 15 times more ...

Not only are they effective against Gram-positive and negative multi-resistant bacteria, they also appear not to trigger resistance when used to treat infection in mice. Such are the promises of the two new antibiotics.
