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

Measuring membrane thickness was previously only possible in artificial membranes—now scientists can do it inside intact cells, providing crucial context for understanding how cells work.

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 ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...
