Using technologies like electron microscopy (EM) it is possible to capture molecular mechanisms in great detail, but not when these mechanisms are currently moving. The field of cryomicroscopy circumvents this limitation by freezing said mechanism in place using cryogenic fluids. Although initially X-ray crystallography was commonly used, the much more versatile EM is now the standard approach in the form of cryo-EM, with recent advances giving us unprecedented looks at the mechanisms that quite literally make our bodies move.
