Summer Students: Live and In-Person
For two short days on the Cornell Campus, the students from around the country - including four students from Puerto Rico - were able to meet their mentors from CHESS and their peers from other community colleges and undergraduate institutions. Their trip to Cornell offered the opportunity to tour the CHESS facility, explore the Ithaca area, and present their summer projects to an audience of CHESS directors, graduate students, and their fellow summer research students.

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.
