A theoretical particle that adapts to its surroundings could explain the accelerating expansion of our universe. Our universe grows a little bigger every day. Empty space is expanding, sweeping galaxies further and furth...

Supercomputer calculation suggests hypothesized particle may be heavier than thought --

The first human test of early time-restricted feeding found that this meal-timing strategy strategy reduced swings in hunger and altered fat and carb burning patterns, which may help with losing weight. In early time-res...

Atoms, photons, and other quantum particles are often capricious and finicky by nature; very rarely at a standstill, they often collide with others of their kind. But if such particles can be individually corralled and c...

Iowa State University researchers have helped demonstrate the existence of a subatomic structure once thought unlikely to exist.

During stroke or heart attack, tissue damage can be limited because "collateral" vessels connect the tissue to other arteries. Collateral vessels can vary greatly in size and number from one person to the next. Scientist...

Losing weight may not protect against colon and liver cancer, even though obesity is associated with increased risk of certain types of gastrointestinal malignancy.

A new computational tool called fABMACS is helping scientists see beyond static images of proteins to more efficiently understand how these molecules function, which could ultimately speed up the drug discovery process.

By removing the protein galectin-3 (Gal3), a team of investigators was able to reverse diabetic insulin resistance and glucose intolerance in mouse models of obesity and diabetes.

The impact a scientist will have in their lifetime is distributed randomly over the sequence of studies they publish, according to a new study. This phenomenon can be described by a simple model in which a scientist's im...

A freshwater zebrafish costs less than two bucks at the pet store, but it can do something priceless: Its spinal cord can heal completely after being severed, a paralyzing and often fatal injury for humans. While watchin...

A new study paves the way for understanding how some people stay healthy despite having disease-causing mutations.

Sunshine matters. A lot. The idea isn't exactly new, but according to a recent study, when it comes to your mental and emotional health, the amount of time between sunrise and sunset is the weather variable that matters ...

An international team of researchers has isolated and analyzed genetically tuberculosis bacteria from several thousand patients from over a hundred countries. This analysis demonstrates that the tuberculosis bacteria var...

Scientists have measured the catastrophic genetic damage caused by smoking in different organs of the body and identified several different mechanisms by which tobacco smoking causes mutations in DNA. Researchers found s...

We can now precisely count how many cancer-related DNA mutations accumulate in smokers' organs over time

A computer model watched over two million internet videos and can now accurately identify noises such as door knocks, dog barks, snoring and toilet flushes

Before RNA copies of genes can program the synthesis of proteins, the non-coding regions are removed by the spliceosome. Researchers report that distinct conformations of a member of this molecular complex play a vital r...

Researchers have identified mutations in Ebola virus that emerged during the 2013-2016 Ebola virus epidemic in West Africa that increased the ability of the virus to infect human cells.

Chronic insufficient sleep is at epidemic levels in U.S. teens and has been associated with depression, substance use, accidents, and academic failure. Poor self-regulation or an inability to alter thinking, emotions, an...

New research has begun to elucidate how differences in the gut microbiome - the microbial population of the gastrointestinal tract - affect the immune response in healthy individuals.

What do the Oral-B CrossAction toothbrush, about a thousand musical compositions and even a few recent food recipes all have in common? They were invented by computers, but you won't find a nonhuman credited with any of ...
