Despite vaccines and treatments, SARS-CoV-2-the virus that causes COVID-19-continues to pose a global health threat, driven by new variants and its ability to hijack human cells in ways that still ...

Immunoglobulins (IGs) made by chronic lymphocytic leukemia (CLL) B cells are unique in that they bind themselves (homo-dimerize). This interaction leads to signal transduction with functional ...

Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human biology when mutated. A fundamental discovery is overturning decades of ...

Analysis of ancient proteins may fill in the gaps of human evolution left by the decomposition of DNA. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Left cerebral hemisphere of an adult male buried at the site of the former Blackberry Hill Hospital (Bristol, UK). The surface of the brain’s visible convolutions is stained red with iron oxides.

It is now possible to obtain proteins from preserved soft tissues like brains. The new method could reveal details of human history and prehistory, and of evolutionary history, that were previously ...

Sneaky parasite evades the human immune system by stripping cells and wearing them as a disguise Parasites are known to infect human cells through a variety of ingenious mechanisms. Many of them have ...

Researchers developed a new machine learning method that, given a relevant amino acid sequence, can automatically predict the location of a protein in any human cell line down to the single-cell level ...

Entamoeba histolytica is a single-cell parasite that causes intestinal disease, but sometimes invades the body, attacking cells and creating liquefying abscesses. UC Davis parasitologist Katherine ...

Researchers have extracted ancient proteins from australopithecine fossils and determined whether they were male or female — a first for human evolution studies. When you purchase through links on our ...
