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 ...

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 ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

Measuring membrane thickness was previously only possible in artificial membranes—now scientists can do it inside intact ...
