  • Experiments using high-intensity X-ray pulses incident on high-pressure hydrocarbons suggest that diamond formation can occur at shallower depths in icy planets and may play a role in the internal convection that generates their magnetic fields.

  • Due to the pulsed nature of X-ray free electron laser (XFEL) instruments the majority of protein crystals, which are injected using continuous jet injection techniques are wasted. Here, the authors present a microfluidic device to deliver aqueous protein crystal laden droplets segmented with an immiscible oil and demonstrate that with this device an approx. 60% reduction in sample waste was achieved for data collection of 3-deoxy-D-manno-octulosonate 8-phosphate synthase crystals at the EuXFEL.

  • 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 multiple FEL pulses interact with the sample without destroying it.

  • The new European X-Ray Free-Electron Laser (EuXFEL) is the first XFEL that generates X-ray pulses with a megahertz inter-pulse spacing. Here the authors demonstrate that high-quality and damage-free protein structures can be obtained with the currently available 1.1 MHz repetition rate pulses using lysozyme as a test case and furthermore present a β-lactamase structure.
