Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

Scientists at St. Jude Children's Research Hospital have characterized a hidden intermediate state at the center of Src kinase function. This hidden state allows the kinase to repeatedly modify its ...

The human cell is a miserable thing to study. Tens of trillions of them exist in the body, forming an enormous and intricate network that governs every disease and metabolic process. Each cell in that ...

Cell biology is a branch of biological sciences that investigates the structure, function, dynamics, and regulation of cells as the fundamental units of life. It encompasses the study of cellular ...

Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research has found that stem cells in the freshwater planarian Schmidtea ...
