TL;DR: In this article, the effects of local damage in serial femtosecond crystallography (SFX), Clostridium ferredoxin was used as a model system, and the electron density maps calculated from high-dose SFX and synchrotron data showed peaks at the iron positions of the clusters, indicative of decrease of atomic scattering factors due to ionization.

TL;DR: Crystallographic ‘snapshots’ taken at intervals of femtoseconds to milliseconds after activation show how a light-activated sodium pump carries sodium ions across the cell membrane and provide direct molecular insight into the dynamics of active cation transport across biological membranes.

TL;DR: This work presents an unsupervised method able to sort experimental snapshots without recourse to templates, specific noise models, or user-directed learning and shows 90% agreement with manual classification.

TL;DR: In this article, the authors modify iterative reconstruction methods to improve tolerance to noise in single-shot coherent diffractive imaging at X-ray free-electron laser facilities, which is limited by the low signal-to-noise level of diffraction data at high scattering angles.

TL;DR: X-ray diffraction data recorded from microcrystals of the Blastochloris viridis photosynthetic reaction centre is presented and its serial femtosecond crystallography structure is determined.
