"Researchers hope to be able to get diffraction patterns from individual molecules, allowing them to watch biomolecules moving and interacting in a completely natural setting, surrounded by water, instead of trapped in the artificial environment of a crystal. That’s my future vision for crystallography. Get away from being a coroner imaging dead molecules, and instead get molecular movies."
