Scientists have managed to ascribe an immunological memory function to a subset of cytotoxic NK cells, which have hitherto been regarded as antigen-non-specific. These cells are therefore an interesting target for prophylactic use in the human immune system in the fight against infections and viruses.

How are signals triggered by traumatic events embedded in germ cells? A new study by Professor Isabelle Mansuy proposes a biological mechanism.

Researchers have tried to understand the formation of these memories in hopes of finding ways to disrupt them as a potential treatment for substance use disorder (SUD). A new study shows that cocaine use in mice leads to the formation of synapses by an unexpected architect: a type of cell called astrocytes.

A laboratory test developed by a research team led by Johns Hopkins University bioengineers can accurately pinpoint, capture and analyze the deadliest cells in the most common and aggressive brain cancer in adults.

Researchers at Duke University have identified a number of “silent” mutations in the roughly 30,000 letters of the virus’s genetic code that helped it thrive once it made the leap to humans, and possibly helped set the stage for the global pandemic.

Using a yield stress gel, Penn State engineers can place tiny aggregates of cells exactly where they want to build the complex shapes that will be necessary to replace bone, cartilage and other tissues.

A research team has used novel single-cell sequencing methods to analyze the expression of transposons in the brains of Drosophila melanogaster fruit flies. Their findings suggest that these "jumping" genes may rewire neuronal function in these somatic cells.

Findings by Monash Biomedicine Discovery Institute (BDI) researchers have pointed to a new combination of treatments that may help breast cancer patients with certain gene mutations.

Both seasonal migration and the maintenance and use of an effective immune system come with substantial metabolic costs. To overcome this, migratory bats favor the energetically “cheaper” non-cellular (humoral) immunity during an immune challenge and selectively suppress cellular immune responses.

In a changing climate, understanding how organisms respond to stress conditions is increasingly important. New work led by Carnegie's Arthur Grossman and Emanuel Sanz-Luque could enable scientists to engineer the metabolism of organisms to be more resilient and productive in a range of environments.
