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 ...

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an ...

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 ...

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 ...

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 ...

A three-dimensional model of different organelle membranes created from high-resolution imaging data reveals that membranes vary in thickness. Darker colors indicate thicker regions of the membrane, ...

Kintsugi, the traditional Japanese art of repairing broken pottery by mending cracks with lacquer and gold. Kintsugi visibly incorporates the history of an object into its new form. In this analogy, ...
