A virus recognizes the starting point on the DNA to be packaged inside its protein shell
A bacteriophage – a virus that attacks bacteria – assembles into an infectious species using a powerful nanomachine to stuff its DNA into a protein shell. In several types of phage, this genome packaging motor is composed of several copies of large and small terminase subunits (TerL and TerS, respectively) that attach to a portal into the protein procapsid.

Women and Girls in Science at CHESS
At CHESS, we are proud to have women in leadership roles that steer the scientific mission of the lab, scientists, postdocs and students who explore the future of materials, and research support specialists and technical experts who ensure that the everyday science at CHESS remains cutting edge. February 11th is the International Day of Women and Girls in Science.
High-pressure small-angle X-ray scattering cell for biological solutions and soft materials
Pressure is a fundamental thermodynamic parameter controlling the behavior of biological macromolecules. In many cases pressure alters molecular shape and therefore also the biological function. Small angle X-ray scattering (SAXS) is a widely used method to determine the shape and size of macromolecules, but typical sample cells for SAXS experiments are unsuitable for use at high pressures.
BioSAXS facility at CHEXS develops stringent anoxic sample environment
From the gut microbiome to the depths of the ocean, life has evolved to thrive in the absence of oxygen. In fact, it is not hyperbole to say that life as we know it would not exist without the oxygen sensitive metalloenzymes that we all rely on.
CHESS receives $32.6M from NSF for new X-ray beamline
The National Science Foundation has awarded the Cornell High Energy Synchrotron Source (CHESS) $32.6 million to build a High Magnetic Field (HMF) beamline, which will allow researchers to conduct precision X-ray studies of materials in persistent magnetic fields that exceed those available at any other synchrotron.
CHESS Restarts for Remote Research
The Cornell High Energy Synchrotron Source, CHESS, has reopened for researchers after a long shutdown due to CoVID-19. Users who typically travel from all over the world to perform research at CHESS are now able to study their samples by logging in remotely from their home institutions.
September 2020 Message from the Directors
Dear Colleagues, At Cornell, the fall semester began on September 2nd with a hybrid approach to teaching (in-person and online), robust virus testing, and modifications to the academic calendar allowing students to return home for Thanksgiving and then finish the semester on-line. Cornell provides information on its web site related to COVID-19 and the status Cornell Ithaca campus.
