Malfunctions in the complex protein "machinery" of serotonin transport can result in depression, obsessive-compulsive disorder, aggression, anxiety, and Parkinson's disease. Now, researchers have obtained x-ray crystallographic structures of the difficult-to-crystallize human serotonin transporter bound to two commonly prescribed antidepressant drug molecules. Read more...

Researchers working at the ALS have recently made new discoveries in understanding the nature of charge storage in lithium-ion batteries, opening up possibilities for new battery designs with significantly improved capacity. Looking at a popular Li-rich cathode material, the researchers used soft x-ray techniques to quantifiably explain oxygen's role in Li-ion charge capacity. Read more...

Getting to the Root of Grapevine Hydraulics

In grapevines, "root pressure" was assumed to play a role in recovering from embolisms (blockages) in a plant's water-transport systems during drought conditions. To clarify this, researchers used ALS Beamline 8.3.2 to obtain 3D microtomographic images of grapevine stem segments detached from roots and leaves. Read more...

 

Mapping the Topology of the Human Genome

To determine how a gene will function, we need to know the spatial arrangement of the genome in the nucleus. Researchers have made a significant advance in determining this 3D organization by combining modeling and probabilistic calculations with minimally perturbing imaging techniques. Read more...

This September, Beamline 7.0.2, MAESTRO, will accept general user proposals for the first time. Its unique attributes combine strong sample preparation capabilities with cutting-edge spectromicroscopy tools, offering researchers unparalleled opportunities for studying the correlation between structure and electronic properties. Read more...

ALS User Daniel Hallinan Jr. Testifies in Congressional Hearing
On June 15, 2016, ALS user Daniel Hallinan Jr., an assistant professor at Florida State University, testified before the US House Committee on Science, Space, and Technology's Subcommittee on Energy. In the hearing, entitled "Innovation in Solar Fuels, Electricity Storage, and Advanced Materials," Hallinan spoke to the importance of DOE's national light sources to research and the technological challenges of the nation, and to the impact of the proposed light source upgrades on research capabilities and US scientific competitiveness. Watch the testimony...
Registration remains open until August 1 for the 12th International Conference on Biology and Synchrotron Radiation, which will be held at SLAC National Accelerator Laboratory August 2124. 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.

Operations Update

For the user runs from June 1 to June 27, 2016, the beam reliability [(time scheduled - time lost)/time scheduled)] was 98.7%. For this period, the mean time between failures (MTBF) was 46.4 hours, and the mean time to recovery (MTTR) was 45 minutes. There were no significant interruptions.

Detailed information on reliability is available on the ALS reliability bulletin board, which is located in the hallway between the ALS and the control room in Building 80. Questions about beam reliability should be directed to Dave Richardson ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it , x4376).

Long-term and weekly operations schedules are available online. Requests for special operations use of the "scrubbing" shift should be sent to ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it ) by 1:00 p.m. Friday. The ring status can be seen in real time at http://www-als.lbl.gov/index.php/beamlines/beam-status.html.
