A new method helps researchers understand how the "moving parts" of a cell function

Microscope image of a yeast cell showing how close mitochondria (red) are to peroxisomes (blue) and the contact sites that hold them together (green)

Weizmann researchers identify new ties between the parts of a cell: physical connections that are vital for health

Left: normal nerve cells; right cells genetically engineered to neutralize MTCH2. Fluorescent proteins reveal the calcium uptake in the mitochondria of these cells. The genetically engineered cells reveal dramatically less calcium uptake – evidence of the crucial role this gene plays in mitochondria function

Understanding how a gene studied in one lab affects the basic element researched in another may reveal what goes wrong in Alzheimer's

The circadian clock regulates the mitochondria’s utilization of nutrients throughout the day

Weizmann Institute scientists find that our cells' power plants run on timers 

A three-dimensional reconstruction of the mitochondrial volume: The volume is larger (yellow and red) in blood-forming stem cells lacking MTCH2 (right), and relatively smaller (blue and green) in regular blood-forming stem cells
