Scientists mix sky's splendid hues to reset circadian clocks In a small study, a novel LED device with alternating orange and blue wavelengths outpaced two other lights in advancing participants ...

There is a challenge related to prostate and many other cancers that cancer cells form resistance to treatments as the disease progresses. However, these resistance mechanisms are not yet fully ...

A new, wide-ranging exploration of human remains casts doubt on a long-standing theory in archaeology known as the Kurgan hypothesis -- which, among other claims, suggests that humans first ...

Scientists now understand why some gray horses turn completely white as they age, while others remain an eye-catching 'dappled' gray color.

A research group has developed a new COVID-19 testing system using Janus particles -- microparticles with two sides possessing distinctive molecular properties. These particles are engineered to bind ...

Researchers have shown that they can generate a strong immune response against HIV with two doses of a vaccine given one week apart.

The Colorado River is a vital source of water in the Western United States, providing drinking water for homes and irrigation for farms in seven states, but the basin is under increasing pressure from ...

A research team has developed a computational workflow for analyzing large data sets in the field of metabolomics, the study of small molecules found within cells, biofluids, tissues, and entire ...

Researchers investigated differences in T-cell responses between male and female patients with lung cancer that may help direct future treatments. T-cell responses are part of the adaptive immune ...

Investigators developed the largest collection of sarcoma patient-derived organoids to date that can help improve the understanding of the disease and better identify therapies that are most likely to ...

Scientists have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysentery, manipulates molecular activity to assure its survival against its host's ...

Fever temperatures rev up immune cell metabolism, proliferation and activity, but they also -- in a particular subset of T cells -- cause mitochondrial stress, DNA damage and cell death, researchers ...
