Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, ...

Bacteria and yeast need to prevent leakage of numerous small molecules through their cell membrane. Biochemists have studied how the composition of the membrane affects passive diffusion and the ...

Cell membranes cradle, protect, and gatekeep living cells. Membranes can even affect how a cell behaves. But membranes' own erratic behavior has puzzled scientists for years. Turns out, it's all about ...

The upper size limit on cell-penetrating drug molecules may be much higher than medicinal chemists had thought. A research team reports that molecules believed to be much too large to diffuse across ...

The plasma membrane is what isolates the cell’s interior from its surroundings. It is made up of a lipid bilayer and other macromolecules, such as carbohydrates, glycoproteins, and membrane proteins, ...

Cell membranes cradle, protect, and gatekeep living cells. Membranes can even affect how a cell behaves. But membranes’ own erratic behavior has puzzled scientists for years. Turns out, it’s all about ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Subscribe to our newsletter for the latest sci-tech ...
