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.

Electrical stimulation of the brain through the vagus nerve increases the motivations to work for food, according to recent findings. These findings demonstrate a novel method to alter motivation to obtain food.

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...

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.

Drugs known as potentiators alleviate some symptoms of cystic fibrosis. Researchers recently figured out how these compounds work--a finding that may lead to better drugs that patients can more easily afford.

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...

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.

A study found that symptom-triggered medication dosing for neonatal opioid withdrawal syndrome instead of infants receiving a fixed schedule of medication with a long taper reduced the length of their hospital stay.

A new protein called KHNYN has been identified as a missing piece in a natural antiviral system that kills viruses by targeting a specific pattern in viral genomes, according to new findings.

More than one-third of Americans are obese, and while more than 250,000 bariatric surgeries are performed annually in the United States, experts say surgery should be an option for many more patients. Researchers say the...

A computer program called the Ramanujan Machine is generating mathematical conjectures for constants like π and e, just like the legendary Indian mathematician

A new study reveals substantially higher risks of death between ages 1-24 for children living in families with lower levels of parental education, lower levels of family income, and/or for those living in a single parent...

Duchenne muscular dystrophy occurs in boys and is characterized by progressive muscle degeneration and weakness leading to a decline in respiratory function. Strategies to arrest this severe progressive deterioration are...

In a meta-analysis of real-life experiments drawn from food science, nutrition, health economics, marketing and psychology, the authors find that behavioral nudges -- facilitating action rather than providing knowledge o...

A new study finds potent antibacterial capabilities in novel dental restoratives, or filling materials.

Researchers propose the evolutionary dynamics of background extinctions suggest this focus on finding new and better drugs may have neglected opportunities to develop new and better treatment strategies to improve outcom...

Scientists have developed a new methodology that allows the study of CRISPR-mediated effects in cells while accurately ascertaining the exact DNA changes that caused them. This novel protocol is opening up new avenues of...

A vacuum is generally thought to be nothing but empty space. But in fact, a vacuum is filled with virtual particle-antiparticle pairs of electrons and positrons that are continuously created and annihilated in unimaginab...
