From Our Director

SSRL just completed our DOE Basic Energy Sciences Triennial Review. The review highlighted the high impact of SSRL user science, the quality of SSRL user support, the reliability of SPEAR3 performance, and a strong commitment to science education. I would like to thank the user community, the SSRL User Executive Committee in particular, and the SSRL staff for your essential roles in making SSRL a successful scientific organization. One example shared with the reviewers was the user surveys, which documented an exceptionally high level of user satisfaction. Thank you for your support!

In preparation for the Triennial Review, we have reinvigorated our Strategic Plan, which you can find at the SSRL home page. Our planning includes three new undulator beam lines, and two new bending magnet beam lines, all in construction, and an increasing commitment to in-situ and operando measurements, x-ray emission and Raman measurement throughout the x-ray spectrum, and picosecond science. For details, please see the Strategic Plan. Keeping our plan current and compelling is critical and we ask for your continued contributions to our planning.

Thermodynamic Preservation of Carbon in Anoxic Environments Contacts: Kristin Boye and John Bargar, SSRL

While scientists recognize that oxygen-free soil stores large amounts of carbon, knowledge about the processes that protect and preserve carbon-rich molecules in these environments is lacking. In oxygen-rich soil, microbes break down organic molecules through aerobic respiration, allowing carbon to escape the ground as carbon dioxide gas.  Read more...

Perseverance Pays Off in Fight Against Deadly Lassa Virus

Excerpt from June 1, 2017 News Release

Before Ebola virus ever struck West Africa, locals were already on the lookout for a deadly pathogen: Lassa virus. With thousands dying from Lassa every year—and the potential for the virus to cause even larger outbreaks—researchers are committed to designing a vaccine to stop it. A team at The Scripps Research Institute (TSRI) led by Staff Scientist Kathryn Hastie and Professor Erica Ollmann Saphire has solved the structure of the viral machinery that Lassa virus uses to enter human cells using diffraction data collected at SSRL BL12-2. Their study, published June 2, 2017 in the journal Science, is the first to show a key piece of the viral structure, called the surface glycoprotein, for any member of the deadly arenavirus family. Importantly, the new structure provides a blueprint to design a Lassa virus vaccine.  Read more...


Meeting Summary

RapiData 2017

The RapiData 2017 practical workshop in macromolecular x-ray crystallography was hosted by the Structural Molecular Biology (SMB) group at SSRL during April 16-21, 2017. The continuing aim of this course is to educate and train young scientists in data collection and processing methods at synchrotron beam lines, using state-of-the-art software and instrumentation. The co-organizers of the 2017 course were SSRL scientists Ana Gonzalez, Clyde Smith and Silvia Russi. The 2017 course attracted 43 early career scientists, mainly postgraduate students and postdoctoral researchers, but also some master students, research staff and junior faculty from around the world. One important mandate for all the previous RapiData courses has been to encourage attendance by young scientists from Latin America with the assistance of scholarships from the International Union of Crystallography (IUCr).

On Sunday April 16, Bob Sweet (Brookhaven National Laboratory) gave a five-hour lecture course on the fundamentals of crystallography to ensure that students without much previous experience in crystallography benefit fully from the lectures and practicals during the rest of the course. On Monday and Tuesday there were lectures covering topics ranging from light sources, beam line instrumentation, sample preparation, data collection, indexing, integration, phasing and complementary techniques. Participants were also able to tour the serial femtocrystallography facilities at the LCLS. Hands-on tutorials on data reduction and structure solving software started on Tuesday evening and ran in parallel over Wednesday and Thursday, with sample preparation and data collection tutorials at five SSRL beam lines. The course ended on Friday morning with the awards to the winners of the IUCr and Stanford Bio-X travel scholarships, followed by a round table feedback meeting. Both students and speakers and tutors expressed a high degree of satisfaction with the course.
