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 ...

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

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 ...

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 ...

A new study highlights the role of natural killer T cells in influencing the immune response to dengue virus, potentially reducing the severity of subsequent infections.

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 ...

Large language models (LLMs) have developed rapidly in recent years and are becoming an integral part of our everyday lives through applications like ChatGPT. An article explains the opportunities and ...

Researchers have found microplastics less than 300 m in size in coral skeletons. The team developed a new protocol to extract and detect microplastics and applied it to coral samples from the Gulf of ...
