After a severe case of flu, mice have chemosensory cells in their lungs, a place where they don’t normally occur.

A small study finds that the tiny extracellular vesicles from patients with hepatocellular carcinoma have RNA content distinct from patients with cirrhosis only.

Lab-grown stem cells fill in for damaged tissue in the noses of mice.

Analyzing protein-protein interactions can shed light on what tiny proteins do in the cell.

Advances in the functional characterization of newly discovered microproteins hint at diverse roles in health and disease.

Two independent studies in rats find grid cells, which form the brain’s map, are more plastic than thought and are subject to the influence of reward.

In cell division, a protein called spastin appears to help tear down a bridge between daughter cells.

Viruses that infect plants and occasionally insects appear to cause infection with a divide-and-conquer strategy, multiplying separate segments of genetic material in different host cells.

A new set of engineered receptors responds to an FDA-approved drug to provide the most potent chemogenetic toolkit to date.
