ACA honors staff scientist Richard Gillilan
Richard Gillilan, a MacCHESS/CHEXS staff scientist, has been named a member of the 2021 class of Fellows of the American Crystallographic Association (ACA), in recognition of his many career achievements, especially the development of a world-class BioSAXS facility at CHESS.
In-Hutch Commissioning of Rotation and Axial Motion System IV (RAMS IV) Load Frame
What did the scientists do?
The main objectives of commissioning were to enable communication between the existing control system of the beamline (SPEC) and the new control system of RAMS IV (Aerotech), and to synchronize triggering of X-ray detectors with positions of the rotation stages on RAMS IV.
Protein unfolded states populated at high and ambient pressure are similarly compact
What is the discovery?
Developing a better understanding of protein folding and unfolding reactions is a significant challenge for structural biology. In a new paper, a team lead by Catherine Royer from Rensselaer Polytechnic Institute reports a high-pressure small-angle x-ray scattering study of the model protein CTL9-I98A in solution, which allows direct observation of the pressure-induced unfolded state.
Next-generation detectors ready for experiments at CHESS
Two new detectors developed by Sydor Technologies are now available for user experiments at CHESS.
CHESS Scientists and Outreach take part in Expanding Your Horizons 2021
Since 1988 the annual Expanding Your Horizons (EYH) conference has been encouraging curious youth to pursue their interests in science, technology, engineering, and maths (STEM). This year three CHESS staff contributed to the virtual event.
Beamlines in Focus: FlexX
FlexX is shorthand for “Flexible Beamline for Macromolecular Crystallography,” where the second, capital “X” stems from a common shorthand for “Crystal,” or “X-tal.” The name also indicates the flexibility of the beamline in accommodating a wide variety of crystallography-related experiments. Finke and the beamline work to accommodate challenging experiments that would be difficult to perform at other beamlines across the U.S.
