In late 2021, a 3D printed house went up in Williamsburg, Virginia. The printed portion of the three-bed two-bath home--that is, the exterior walls--took just 22 hours to go up. The house was a collaboration between Habi...

A new study finds that adult flu vaccination dropped in states with low rates of COVID-19 vaccination, suggesting that decades of successful public health vaccination efforts may be unraveling in the wake of the COVID-19...

A recent Pfizer or Moderna mRNA-vaccine booster provided good but temporary protection against infection by the SARS-CoV-2 Omicron variant, according to a new study.

People with two of the diseases, type 2 diabetes, cardiovascular disease or stroke have double the risk of developing dementia, researchers say.

New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new interpretation of an aspect o...

Children with higher cardiorespiratory and muscular fitness and a lower waist-to-hip ratio had higher scores in cognitive tests for attention and processing speed during middle age.

Dopamine in the cerebellum helps regulate social behaviors via its action on D2 receptors. Changes in D2 levels in Purkinje cells alter sociability and preference for social novelty without affecting motor function.

Over-the-counter COVID tests can quickly show whether you are infected with SARS-CoV-2. But if you have a positive result, there's no equivalent at-home test to assess how long you're protected against reinfection. Resea...

We speak to a footwear expert and ask can running shoes be used for walking?

A group of several hundred polar bears in south-eastern Greenland often catch seals by waiting outside their prey's breathing holes on blocks of floating freshwater ice from glaciers, in an example of the animals adaptin...

Meteorite analysis hints that early Mars got important volatile elements like hydrogen and oxygen from meteorite collisions rather than a cloud of gases

A new online atlas can predict how life expectancy is affected by contracting one of 1800 diseases - although the tool may work well only for people in Denmark

Researchers are reporting new technology that not only repairs heart muscle cells in mice but also regenerates them following a heart attack, or myocardial infarction as its medically known.

Researchers have published a detailed collection of mortality estimates for diseases, disorders and external factors. The study provides a resource to estimate reductions in life expectancy for a comprehensive range of d...

A sensor-equipped computer program can accurately identify and count arm movements in people undergoing stroke rehabilitation, a new study shows.

New research shows the mechanism by which genes coding for a subset of long non-coding RNA (lncRNA) interact with neighboring genes to regulate the development and function of essential nerve cells.

A new study has revealed a secret subpopulation of polar bears living in an unusual habitat in southeast Greenland. The new group lives in conditions similar to those predicted for the rest of the Arctic at the end of th...

A quantum simulator at Rice University is giving physicists a clear look at spin-charge separation, the quantum world's version of the magician's illusion of sawing a person in half.

Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers. They are often used in long-distance communication fiber optic cables and fiber-based lasers. Invente...

Scientists have used Xenopus laevis tadpoles to tease out the genetic and biological mechanisms that enhance disease tolerance, and have identified drugs that can keep the tadpoles alive even in the presence of lethal ba...

Humans tend to form groups, which often find themselves in conflict with rival groups. But why do people show such a ready tendency to harm people in opposing groups? A new study led by researchers at Virginia Commonweal...

A drug discovery approach developed -- in part inspired by oil companies -- revealed why drugs for cystic fibrosis fall short.
