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 ...

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 ...

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

In silico antibody accessibility analysis indicates that ectodomain epitopes are transiently exposed, while MPER epitopes are virtually always occluded in the pre-fusion trimer.

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical energy through constant motion in their membranes, offering a fresh way to think ...
