Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used ...

New progress in a long-standing debate about the nature of biological cell membranes could be made by considering which ...

Structure of the cell membrane and conceptual diagrams of (a) short-range viscosity and (b) long-range viscosity. (a) Random thermal motion of lipids on a nanometer scale is not impeded by proteins or ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

A study could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. A new ...

UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps ...
