The ultrafast, ultrabright X-ray pulses offered by a new generation of free-electron lasers is ushering in extraordinary new capabilities in X-ray science, with a wide range of applications in fundamental atomc physics, ultrafast chemistry and materials science. Of particular interest is the ability to study transient material dynamics, and ultimately determine the structures of proteins, viruses and macromolecules that cannot be crystallized.
