Tracking Living Cells as They Differentiate in Real Time
Berkeley Lab and University of California researchers have developed a new technique for monitoring protein phosphorylation inside single living cells, enabling them to follow live cellular chemical changes without bias and without harming the cells. Read more »
ALS Ceramics Materials Research Advances Engine Performance
LBNL senior materials scientist and UC Berkeley professor Rob Ritchie has been researching the fracture behavior of a wide array of materials for the past 40 years, the last ten of them using the facilities at the ALS. From human bone to synthetic engineering materials such as shape-memory metals and composites, Ritchie has illuminated groundbreaking cracking patterns and the underlying mechanistic processes using the x-ray synchrotron micro-tomography at ALS Beamline 8.3.2.
Industry Group Learns About Light Source Opportunities
The Silicon Valley Leadership Group hosted a meeting to introduce its members to the area’s light sources and how they help advance innovation and promote economic competitiveness. The event was sponsored by Congresswomen Zoe Lofgren and Anna Eshoo together with Berkeley Lab (LBNL) and SLAC National Accelerator Laboratory. Read more »
Industry Expert Helps ALS Scientists Craft Relevant Research
Steve Harris has worked for U.S. auto manufacturers for the past 30 years as a research scientist, testing and investigating various promising materials and technologies. As a result, Harris knows a thing or two about what the industry values. Harris is now at the ALS as a visiting scientist, sharing his insight and knowledge with ALS staff scientists working on battery research. Their results could help drive the future of battery-powered transportation in this country.
Structural Biology Helps Drug Discovery
Last year, drug discovery company Plexxikon made front-page news with its highly successful anti-cancer drug, Zelboraf, a product that was chemically optimized using data from ALS x-rays. Designed to disrupt malignant melanoma, the drug was so successful in human testing that trials were halted so that patients in the trial could all be given Zelboraf. Zelboraf marked a significant advancement for patients with metastatic melanoma who historically have had very limited treatment options.

Wine, Water, and X-Ray Tomography
ALS user Andrew McElrone’s research on grapevine rootstock water transport physiology is key to the future of California’s grape-growing industry. The plant biologist’s ultimate goal is to develop sustainable water use strategies for growers, giving them hard data about how much drought their plants can sustain and which species are ideal for an agricultural future with an uncertain water supply.
Corie Ralston: New Head of Berkeley Center for Structural Biology…and Award-Winning Writer
Corie Ralston’s appointment as Head of the Berkeley Center for Structural Biology (BCSB) has her busy looking at budgets, funding, and big-picture goals. The biophysicist staff scientist has been with BCSB for more than 10 years, so much of what she’s considering comes from an intimate familiarity with the day-to-day operations and challenges of theRead More Read more »
Direct Kinetic Measurements of a Criegee Intermediate
“Criegee intermediates” are elusive molecules that play a pivotal role in atmospheric chemistry and are also byproducts of key combustion reactions. At the Chemical Dynamics Beamline, the reaction rates of one form of Criegee intermediate was directly measured for the first time, with some surprising results. Read more »
Two Novel Ultra-Incompressible Materials
Materials that are mechanically, thermally, and chemically stable at extreme conditions are valuable for aerospace engineering and fission/fusion research. Researchers have synthesized and characterized two such materials: Re2N and Re3N are both extremely incompressible. Read more »
