X-ray free-electron lasers (XFELs) are unique tools that are making possible time-resolved measurements of structural and electronic dynamics at the quantum spatial and temporal scales. Jonathan Marangos discusses the transformative scientific potential of this capability but also stresses the importance of lowering barriers to access to maximize scientific reach.
