Scientists who make movies of molecules in motion have a new high-speed camera to shoot with. The €1.2-billion (US$1.4-billion) European X-ray Free Electron Laser (XFEL) will start running its first experiments in September near Hamburg, Germany. The European XFEL fires powerful X-rays in bursts of a few hundred femtoseconds: so short that, like strobe lights, they can capture snapshots of jittery molecules frozen in time, and with a wavelength small enough to provide pictures at atomic resolution.

Mix-and-inject serial crystallography (MISC) is a technique designed to image enzyme catalyzed reactions in which small protein crystals are mixed with a substrate just prior to being probed by an X-ray pulse. This approach offers several advantages over flow cell studies. It provides (i) room temperature structures at near atomic resolution, (ii) time resolution ranging from microseconds to seconds, and (iii) convenient reaction initiation.

BioXFEL researcher Peter Schwander released a publication, along with his peers, to Nature Methods
Using a manifold-based analysis of experimental diffraction snapshots from an X-ray free electron laser, we determine the three-dimensional structure and conformational landscape of the PR772 virus to a detector-limited resolution of 9 nm. Our results indicate that a single conformational coordinate controls reorganization of the genome, growth of a tubular structure from a portal vertex and release of the genome.

A research collaboration led by the University of Wisconsin-Milwaukee has for the first time created a three-dimensional movie showing a virus preparing to infect a healthy cell.
The research has the potential to fundamentally advance our understanding of how biological processes inside the cell work. That could lead to better treatment for the horde of human diseases caused by viruses.
The feat was made possible by UWM physicists, who developed a new generation of powerful algorithms to reconstruct sequential images from an ocean of unsorted, noisy data.

BioXFEL scientist Vadim Cherezov and his colleagues released a new publication to CellPress:
X-ray free electron lasers (XFELs) have the potential to revolutionize macromolecular structural biology due to the unique combination of spatial coherence, extreme peak brilliance, and short duration of X-ray pulses. A recently emerged serial femtosecond (fs) crystallography (SFX) approach using XFEL radiation overcomes some of the biggest hurdles of traditional crystallography related to radiation damage through the diffraction-before-destruction principle.

BioXFEL scientist Richard A. Kirian, along with his peers, published a research article onto IUCrj:
This study explores the capabilities of the Coherent X-ray Imaging Instrument at the Linac Coherent Light Source to image small biological samples. The weak signal from small samples puts a significant demand on the experiment. Aerosolized Omono River virus particles of ∼40 nm in diameter were injected into the submicrometre X-ray focus at a reduced pressure.
