Role of an Oxygen Vacancy Nanostructure on the Switchable
Photovoltaic Effect in BiFeO3 – Contact: Jun-Sik
The list of mechanical and electronic uses for oxide materials is
continuously growing, piquing researchers’ interest in how the
microscopic properties of these materials affect their functionalities. Oxygen
vacancies, which affect electron hopping, have long been identified as a defect
in oxide compounds, but researchers now view them as a way to create new,
potentially useful, behaviors. Read more...

Geochemical Triggers of Arsenic Mobilization during Managed Aquifer
Recharge – Contact: Scott Fendorf (Stanford
The practice of storing reclaimed or storm water by refilling an aquifer is
called managed aquifer recharge (MAR). Advantages of MAR to regions vulnerable
to drought or which have depleted aquifers include water storage for future
use, reduced water loss of stored water from evaporation, and stabilization of
the aquifers. However, refilling aquifers can change the chemistry, allowing
naturally occurring toxins in aquifer sediments to dissolve into the water.
Arsenic, a potential poison, is of particular concern, since use of MAR has led
to arsenic-contaminated water.
Discovery of Next Generation RAF Inhibitors that Dissociate
Paradoxical Activation from Inhibition of the MAPK Pathway –
Contact: Ying Zhang (Plexxikon, Inc.)
Mutation of the gene coding for the BRAF kinase, an important enzyme in the
mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase
(ERK) pathway, can lead to melanoma, an aggressive skin cancer. The
pharmaceutical company Plexxikon has developed drugs, like vemurafenib, that
treat metastatic melanoma harboring BRAF mutation. Read more...
Beam Line Update
BL4 Optics Upgrade Scheduled May-July 2016
In order to better serve our users, we have planned an upgrade to Beam Line
4 (BL4-1, BL4-2, and BL4-3) in 2016 to address degraded mirror performance over
the last several years. After evaluating the SSRL-wide upgrade needs as well as
limitations in available staff and resources, we have determined, considering
all other options, that the best window for the BL4 mirror upgrade is May to
July. We anticipate recommissioning the BL4 mirror systems in July just
prior to the annual summer shutdown.
We understand that this temporary outage of BL4 will likely disrupt user
proposals and planned experiments. We ask for your patience as we work to
provide you with enhanced capabilities, and we appreciate your continued
support and communication.
SSRL School on Synchrotron X-ray Scattering Techniques
in Materials & Environmental Sciences, June 21-23, 2016, Menlo Park,
SSRL EXAFS/Imaging Summer School, July 18-22, 2016,
Menlo Park, CA
12th International Conference on Biology and
Synchrotron Radiation, August 21-24, 2016, Menlo Park, CA
The International Biology and Synchrotron Radiation (BSR)
meetings are held every three years with the aim of presenting and discussing
state of the art applications in relevant research fields, providing a unique
opportunity to discuss the novel possibilities of synchrotrons and x-ray lasers
and to promote their applications to challenging biological problems.
This meeting provides a forum for scientists involved in
research and development on synchrotron and free electron laser sources to come
together with a broad community of biologists, with the ambition to make the
best use of the most advanced infrastructures in structural biology. Possible
applications range from atomic-resolution and time-resolved structures of
biological macromolecules, medium resolution images of the largest molecular
complexes in the living word, and cellular and sub-cellular structures.
Scientists at all possible career levels are invited to this
meeting – ranging from graduate students, postdoctoral fellows, and
principal investigators both from academia and industry. There will be ample
opportunities for individual presentations. Conference

The Stanford Synchrotron Radiation Lightsource (SSRL) is a third-generation
light source producing extremely bright x-rays for basic and applied
research. SSRL attracts and supports scientists from around the world who
use its state-of-the-art capabilities to make discoveries that benefit society.
SSRL, a U.S. DOE Office of Science national user facility, is a Directorate of
SLAC National Accelerator Laboratory, operated by Stanford University for the
U.S. Department of Energy Office of Science. The SSRL Structural
Molecular Biology Program is supported by the DOE Office of Biological and
Environmental Research, and by the National Institutes of Health, National
Institute of General Medical Sciences. For more information about SSRL science,
