Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

This is a diagram showing cholesterol's (red) predominance in the outer layer of the cell membrane. Cholesterol transport proteins (blue) can alter its distribution between the inner and outer layers.

In nature, the cell membrane has a unique function of protecting the internal from the external environment and communicating outside by sensing the external chemical or physical stimuli like the most ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

Scientists describe the design and construction of artificial membrane channels, engineered using short segments of DNA. The DNA constructions behave much in the manner of natural cell channels or ...

The membranes of cancer cells are more pliant than the membranes of normal cells. A research collaboration has discovered that cancer invasion and migration can be supressed in mice by manipulating ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical ...

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...
