Unwinding bacterial enzymes: X-ray revelations
Date: Nov 15, 2019
Author: David Bradley
X-ray crystallography undertaken at the Canadian Light Source in Saskatchewan, and the Advanced Photon Source in Illinois, USA, have given scientists an ultra-high resolution three-dimensional structure of non-ribosomal peptide synthetases, NRPS enzymes, The work could lead to new therapeutic approaches to treating bacterial infection.

Journal Highlight: Graphene metamaterials for intense, tunable and compact extreme ultraviolet and X‐ray sources
Date: Nov 5, 2019
Author: spectroscopyNOW
A unique free‐electron light source has been developed using multilayer graphene metamaterials to support plasmonic modes that interact with an electron beam, paving the way to high‐yield compact tunable sources of extreme UV to X‐ray light.

Enzyme microscopy: X-rays usurped
Date: Sep 15, 2019
Author: David Bradley
Cryo-electron microscopy, as opposed to X-ray crystallography, has allowed researchers in Germany to obtain a structure for a key enzyme complex involved in DNA repair and to trace the conformational changes that take place while it does its job.

Journal Highlight: Microsecond time‐resolved X‐ray diffraction for the investigation of fatigue behavior during ultrasonic fatigue loading
Date: Sep 9, 2019
Author: spectroscopyNOW
A new method based on time-resolved X-ray diffraction is proposed in order to measure the elastic strain and stress during ultrasonic fatigue loading experiments.

Prawn to be wild: Chitosan nanocatalyst support
Date: Aug 15, 2019
Author: David Bradley
Energy dispersive X-ray spectroscopy (SEM/EDS) and various other techniques have been used in a new study that could see chitosan, the material from waste shrimp shells, be used as a substrate for a palladium nanoparticle catalyst in an ionic liquid for efficient and "green" hydrogenation reactions.

Journal Highlight: High‐precision X‐ray spectroscopy of Fe ions in an EBIT using a micro‐calorimeter detector: First results
Date: Aug 5, 2019
Author: spectroscopyNOW
A micro‐calorimeter X‐ray detector of the maXs‐30 type has been used to record the X‐ray radiation from Fe ions produced in the S‐EBIT‐I electron beam ion trap, moving one step closer to the use of maXs‐type detectors as standard instrumentation at GSI/FAIR.

Bacterial protection racket: X-rays reveal mechanism
Date: Jul 15, 2019
Author: David Bradley
X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy have been used in parallel to investigate the mechanism by which some forms of bacteria can protect themselves against chemical attack. The research could help in the fight against bacterial resistance and so-called superbugs.
