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

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, ...

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

Researchers have discovered that damage to the cell membrane promotes cellular senescence, or cell aging. Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap ...

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 ...

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 ...

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 ...

Cancer cells are adept at escaping death. One of the ways in which cancer cells prevent death from fatal attacks by cytotoxic T lymphocytes (CTLs) is by efficiently repairing damage to their cell ...

Morphogenesis is nature's way of building diverse structures and functions out of a fixed set of components. While nature is rich with examples of morphogenesis—cell differentiation, embryonic ...

Nanoparticles built from red blood cell membranes and loaded with a sound-sensitive dye kill liver cancer cells when ...
