Damaged lysosomes are repaired by a lipid-based signaling pathway dubbed PITT that could be targeted to treat neurodegenerative disease, its discoverers say.

Stressed cells can form hollow actin bridges to neighbors to get help, but the virus may hijack these tiny tunnels for its own purposes, a study suggests.

At about 2 centimeters in length, Thiomargarita magnifica tests scientists’ notions of how large microbes can grow.

Researchers explore the idea that molecular patterns in individual cells could underlie the development of a left and a right in animals.

Researchers use imaging to show how actin fibers tilt and then swirl to create left-right asymmetry in the cell.

An RNA-modifying enzyme passed to daughter cells during budding allows yeast cells to switch between faster- and slower-growing phenotypes.

As the year draws to a close, we look back on researchers we bid farewell to, and the contributions they made to their respective fields.

Beyond The Scientist’s coverage of COVID-19’s molecular underpinnings were many other stories highlighting the advances made in scientists’ understanding of the biology of cells.

Researchers identified a novel mechanism by which chemically induced stress is “remembered” by the mitochondria of worms more than 50 generations after the original trigger.

By viewing countless hours of expectorating worms, researchers discover a unique way in which neurons control the movement of muscles.

Immunologists and parasitologists are working to revive the idea that helminths, and more specifically the molecules they secrete, could help treat allergies and autoimmune disease.

Research in animals and people supports a range of mechanisms by which the parasites affect physiology and immune responses.

Neurons stressed with chemicals produce Wnt, which in turn triggers changes in the germline.
