Facial recognition is set to have a significant impact on our society as a whole. While many consumers are familiar with the concept because of the many smartphone apps that let them add various filters, graphics and eff...

A brain penetrant drug -- a small-molecule mimetic of BDNF, or brain derived neurotrophic factor -- is able to improve brain performance in Rett syndrome mice -- specifically synaptic plasticity in the hippocampus and ob...

Diagnosing Alzheimer's disease and determining a patient's prognosis is an inexact business, and that stands in the way of better personalized care and advances in treatment. A new study has identified a potential new wa...

Antibiotics are lifesaving drugs, but overuse is leading to antibiotic resistance, one of the world's most pressing health threats. Scientists identified 11 genetic markers in blood that accurately distinguished between ...

Simulations developed by mathematicians provide new details of how sickle cell disease manifests inside red blood cells, which could help in developing new treatments.

Food scientists have found that people with a diminished ability to taste food choose sweeter -- and likely higher-calorie -- fare. This could put people on the path to gaining weight.

Scientists identified two new populations of cells in the brain that potently regulate appetite. The two types of cells, located in a part of the brainstem called the dorsal raphe nucleus, are potential targets for new d...

Biologically simple they may be, but planarian flatworms have evolved two completely different ways to detect light - and one doesn't involve their heads

Summer may be winding down for those readers in the United States, but don't despair--there is at least one fantastic reason to be excited about August. THE SOLAR ECLIPSE IS COMING![We know many Physics Buzz readers don'...

Blue light emitted from digital devices could contribute to the high prevalence of reported sleep dysfunction, suggests new research.

A biologist in Oregon has successfully used CRISPR to edit single-celled embryos carrying severe genetic defects.

In science, a law describes an observed phenomenon.

The protein amyloid beta is believed to be the major cause of Alzheimer's disease. Substances that reduce the production of amyloid beta, such as BACE inhibitors, are therefore promising candidates for new drug treatment...

A new study involving mice, suggests that EGCG (epigallocatechin-3-gallate), the most abundant catechin and biologically active component in green tea, could alleviate high-fat and high-fructose (HFFD)-induced insulin re...

The structure of a protein key to the survival and spread of a virus that affects salmon could help researchers form strategies to treat the flu in humans.

Repairing spinal injuries is a difficult business. Scientists previously developed a new surgical technique to reconnect sensory neurons to the spinal cord after traumatic spinal injuries. Now, they have gained new insig...

A new study has found that walnuts in the diet change the makeup of bacteria in the gut, which suggests a new way walnuts may contribute to better health.

A study of lead service lines in Flint's damaged drinking water system reveals a Swiss cheese pattern in the pipes' interior crust, with holes where the lead used to be. The findings support the generally accepted unders...

(Phys.org)--Researchers have designed an optical lens that exhibits two properties that so far have not been demonstrated together: self-focusing and an optical effect called the Talbot effect that creates repeating patt...

The female sex hormone estrogen plays an important role in the structural stability of bones. To date, however, it had been unclear exactly which cells were involved in the hormone's protective function. Researchers have...
