A close-up of biological nanomachines: Researchers take a deep look at peroxisomal processes

Every system has its waste disposal system. The cell organelles known as 'peroxisomes' dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. Researchers have now shown, at the atomic level, how these highly complex processes proceed.
