On a microscopic level, every function of life is performed by biological macromolecules. To understand how these molecular machines work, it is necessary to know the three-dimensional structure of their constituent protein complexes. Recently, a breakthrough in protein structure studies has been brought about by a series of technological advances in transmission electron microscopes, imaging tools that use electron beams to probe the specimen.

In a recent experiment that brings quantum physics to the aid of molecular biology, we used high power laser beams to manipulate the electrons in order to maximize the image contrast of a transmission electron microscope.
