Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

A new imaging approach is shedding light on one of cell biology’s most elusive questions: how lipids are organized and sorted within membranes.

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Until now, scientists could only measure membrane ...

Biological membranes of cells and their subunits (organelles) are organized into tiny regions (nanodomains) made up of fats ...

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 ...

Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating ...

Cholesterol is an essential component of the membrane surrounding every human cell, despite its poor reputation as a health concern when its blood levels are too high. The key to health is having the ...

Protein-mediated cell membrane repair protects cancer-derived cells against T cell attack, researchers report. The findings reveal new insights into how tumor cells escape death, which could be ...

The original version of this story appeared in Quanta Magazine. The bottom of the ocean is cold, dark, and under extreme pressure. It is not a place suited to the physiology of us surface dwellers: At ...

The cell membrane is the cell's outermost line of defense against SARS-CoV-2, the novel coronavirus responsible for COVID-19 disease. Cell membranes are just a few nanometers thick but are essential ...
