This paper presents recent technical improvements to the VitroJet and the benefits that it brings to the cryo-EM workflow, as well as a wide variety of case studies. This illustrates the advancement of the VitroJet into an instrument that enables accurate control and reproducibility, demonstrating its suitability for time-efficient cryo-EM structure determination.

EMinsight is a Python-based tool for systematically mining metadata from single-particle analysis cryoEM experiments. The capture and analysis of metadata facilitates the assessment of instrument performance, provides concise reporting of experiment performance and sample quality by analysing preprocessing results, and gathers metadata for deposition. It is envisaged that this approach will benefit the microscope operator, facility managers, database developers and users.

The structure determination of a small protein of unknown function by molecular replacement using a search model predicted by new machine-learning methods is reported. Notably, the approach was successful using electron diffraction data collected from a protein microcrystal, highlighting a potentially important new route for structure determination.

A sample- and time-efficient method to obtain serial crystallography data from batch-grown microcrystals dispensed as drops on a 96-well crystallization plate is described. This offers a versatile method to obtain low-dose room-temperature structures and guide the optimization of microcrystallization for synchrotron and XFEL serial crystallography experiments.
