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, ...

How life arose remains a looming question in science that researchers are seeking to answer by studying the features shared among life today. Everything alive is made up of cells, and what made the ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

Rapid urbanization, population growth, and industrial activities are placing increasing pressure on urban water systems. Contamination from industrial ...

From the fluid mosaic model to tight junctions, cell membranes are the ultimate gatekeepers of life. They manage what comes in and out, maintain balance, and even signal to other cells. Understanding ...

Epiretinal membrane (ERM) is a semi-clear membrane that can form over your retina’s inner surface. It often causes minimal symptoms, but some people have vision loss or distorted vision. Your retina ...

Researchers analyzed which molecules can pass through membranes to learn why all life today uses building blocks with a certain “handedness” How life arose remains a looming question in science that ...
