TL;DR: This simultaneous XRD-XES study shows that the PS II crystals are intact during measurements at the LCLS, not only with respect to the structure of PS II, but also with regard to the electronic structure of the highly radiation-sensitive Mn4CaO5 cluster, opening new directions for future dynamics studies.

TL;DR: The spectra show that the initial O-O bond formation, coupled to Mn-reduction, does not yet occur within 250 μs after the third flash, and the initial frames in a molecular movie of the structural changes during the catalytic reaction in photosystem II are represented.

TL;DR: An electrospun liquid microjet has been developed that delivers protein microcrystal suspensions at flow rates of 0.14-3.1 µl min(-1) to perform serial femtosecond crystallography (SFX) studies with X-ray lasers, extending SFX to biological samples that necessitate minimal sample consumption.
