High-energy (HE) x-ray diffraction (energies 30 keV and above) have long been a mainstay at CHESS, supporting many user groups on a wide variety of in-house developed techniques.

Proteases, enzymes that cleave proteins, are found both free-floating and embedded in membranes. Reactions involving the former are well understood, but the workings of the latter have remained mysterious – how are reactions controlled inside the viscous, two-dimensional membrane, from which water is excluded?

DNA in the cell must be stored in a compact form (or it wouldn't fit) that also allows it to be translated to RNA, and to be copied when a cell divides.

Lynden Archer, the William C. Hooey Director and Professor of Chemical and Biomolecular Engineering, has received the 2014 Nanoscale Science and Engineering Forum (NSEF) Award from the American Institute of Chemical Engineers (AICHE).

Dynamic protein-nucleic acid complexes are central to molecular biology. For example, protein-RNA interactions hold the ribosome together, while protein-DNA interactions contain DNA in chromatin.

BioSAXS experiments require careful preparation. Many users (even though they may be experienced crystallographers) are new to the technique, and MacCHESS' Richard Gillilan and Alvin Acerbo spend a great deal of time “holding hands” of biologists using the BioSAXS facility for the first time.

Last week, Ithaca Generator (IG) partnered with Xraise, the outreach program at the Cornell Laboratory for Accelerator-based Sciences and Education, to host a week-long GERLS Camp for middle school girls.

Not many summer students can say they have configured hutches, built beamlines, and spent all night in the lab running experiments and collecting data.
