Biologists have long treated cell membranes as passive barriers, thin skins that separate the chemistry of life from the ...

Biologists have long treated the cell as a chemical factory, but a new wave of research is forcing a rethink of that familiar ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ensure the signal reaches the correct effector without triggering pathways ...

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 ...

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 ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

Researchers have uncovered a previously unrecognized role for immune cell surface sugars in driving inflammation in psoriasis. Scientists have refined how they understand the role of sugars called ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...

Living cells may generate electricity through the natural motion of their membranes. These fast electrical signals could play ...
