Researchers find so-called integrons, previously known only in bacteria, in their distantly related microbial relatives. 

Natural science research projects were among those promised funding by the now-collapsed crypto exchange’s “effective altruism” foundations.

The tiny strings of RNA promote translation of a protein implicated in cancer, a hint they could regulate gene expression in more ways than previously thought.

Mycobacterium leprae appeared to reprogram the animals’ livers to a state partially resembling early development, resulting in healthy organ growth.

Union-represented workers are walking out for an indefinite period of time after negotiations over their compensation and other issues stalled.

Study authors say the teeth, dated around 780,000 years old, push back the date humans are known to have engaged in cooking by more than 600,000 years. 

Researchers find signatures pre- and post-vaccination that correlate with a more robust immune response. 

An unexpected find shows that sweet-sensing receptors also help epithelial cells in Drosophila larvae stay alive amid proteotoxic stress.

Aberrant immune activation, the main cause of prematurity and stillbirths, could be preventable through interventions such as maternal vaccination. 

The relative sizes of specific parts of the guppy brain may explain why some fish are better at learning certain tasks than others. 

The ability to activate different sets of genes has likely helped the chytrid fungus Batrachochytrium dendrobatidis spread widely in amphibians, resulting in global population declines. 

A high-fat diet induced changes to the animals’ vaginal microbiomes that boosted survival after exposure to the virus.
