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

Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human hair, each cell contains a dense mix of proteins, organelles, and molecular ...

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

A team of scientists led by the Institute for Glial Sciences (IGS) at Case Western Reserve University's School of Medicine has discovered a built-in "brake" that controls when key brain cells mature.

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 ...

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...
