A set of new imaging tools now allows researchers to see how specific fat molecules, called phospholipids, are distributed ...

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, ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) ...

Researchers at the University of Michigan have revealed that cells use a previously unknown feat of molecular craftsmanship ...

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular ...

Hemifusomes are fused vesicles, or sacs of fluid, that were previously unknown to exist inside cells. They were discovered using cryo-electron tomography, which literally freezes them in time, and ...

Cells behave like cities and organelles carry out infrastructural roles: mitochondria are powerhouses, the endoplasmic reticulum serves as a transport hub and lysosomes help with waste disposal.

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...
