Free-electron lasers are capable of high repetition rates and it is assumed that protein crystals often do not survive the first X-ray pulse. Here the authors address these issues with a demonstration of multi-hit serial crystallography in which mult

During bacterial cell division, the protein FtsZ is the main component of the contractile ring, though how precisely FtsZ treadmilling and its ability to deform membranes cooperate are unclear. Here, the authors show that dynamic FtsZ may deform lipi
