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, ...

In a landmark simulation, scientists have recreated the full cell cycle of a living cell in four dimensions — three ...

Many drug and antibody discovery pathways focus on intricately folded cell membrane proteins: when molecules of a drug candidate bind to these proteins, like a key going into a lock, they trigger ...

Lipids, or fats, are essential to life. They form the membranes around cells, protecting them from the outside. In nature, there is an enormous diversity of lipids, with each organism having its own ...

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

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 ...

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

Cells behave like cities and organelles carry out infrastructural roles: mitochondria are powerhouses, the endoplasmic ...
