Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...

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 ...

Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human hair, each cell contains a dense mix of proteins, organelles, and molecular ...

A new study maps millions of cells across organs and shows how aging changes the body in coordinated and surprising ways.

Add Yahoo as a preferred source to see more of our stories on Google. Conceptual illustration of the bidirectional quantitative scattering microscope, which detects both forward and backward scattered ...

The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's ...

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal ...

Drugs made of mRNA have the potential to transform medicine—if only they could get into cells in one piece. Now, University ...
