Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do ...

In mouse brain cells, and in follow-up work involving worms and human cortical neurons, the team found that many axons ...

Cells use a surprising “pearling” motion to evenly distribute mitochondrial DNA. This newly uncovered process may be key to ...

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 ...

Far from being a static shell, the cell membrane is a fluid, selectively permeable phospholipid bilayer embedded with proteins, carbohydrates, and cholesterol. It regulates transport, supports ...
