Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

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 ...

A study could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. A new ...

The upper size limit on cell-penetrating drug molecules may be much higher than medicinal chemists had thought. A research team reports that molecules believed to be much too large to diffuse across ...

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 ...

(MEMPHIS, Tenn. – December 5, 2025) 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 ...
