Inside cells, there exists an extensive system of canals known as the endoplasmic reticulum (ER), which consists of membrane-encased tubes that are partially broken down as needed—for instance ...

The study added evidence that the endoplasmic reticulum serves as the central hub of the cell, and looks like a mesh, interacting with nearly everything else. Other researchers are excited about ...

University of Western Australia research reveals how cells convert physical exercise forces into energy production responses.
