Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the metabolism of the cell, they also play a key role in the integration of signals ...

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

A new imaging approach is shedding light on one of cell biology’s most elusive questions: how lipids are organized and sorted within membranes.

International research team presents new imaging technique to make lipids in cellular membranes visible and show how they are organized at the nanoscale. To the point: 3D visualization of lipids with ...

For years, biomolecular condensates were thought to be simple, liquid-like droplets with little internal organization. New ...

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 ...

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 ...

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 ...
