Northwestern Medicine scientists have discovered that two key cellular structures, called mitochondria and lysosomes, come into direct contact with each other in the cell to regulate their respective functions. This rare ...

Building bridges within the cell—using light

Each cell in the body is made up of a number of tiny sealed membranous subunits called organelles, and they send things like lipids back and forth to allow the cell to function. A process called membrane tethering is responsible ...

Discovering what keeps cellular cargo on track

Michigan State University researchers, for the first time, have identified how plants' largest cell factory moves to maintain vital functions, which could lead to advances in improving plant cells' critical functions and ...
