2015 Director’s Awards

ALS staff took top honors in Lawrence Berkeley National Lab’s 2015 Director’s Awards for Exceptional Achievement and were recognized in a ceremony earlier this month. The ALS recipients comprised nearly half of this year’s awardees, receiving recognition in the scientific, early scientific career, and safety categories. The Director’s Awards honor individuals in both the scientific and operations divisions forRead More Read more »

Custom Organic Electronics Out of the Printer

Using in situ x-ray characterization and a custom-made slot-die coater at Beamline 7.3.3, the cross-linking of polymer molecules in the active layer of an organic solar cell during the printing process could be observed.

2015 ALS User Meeting Highlights

The 2015 User Meeting brought together 405 ALS users from around the world, many of whom shared insights and sparked discussion with presentations of their ALS research highlights. Read more »

SIBYLS Beamline Builds on Nobel Research

Often the full impact of a scientific discovery takes decades to realize, during which the research is developed further and adopted by other scientists. Such was the case for the work of biochemist Paul Modrich, one of three recipients of this year’s Nobel Prize in Chemistry. Berkeley Lab’s Advanced Light Source was a core resource Modrich used to build on his earlier work. Read more »

Ashley White, Director of Communications

After many years as a researcher followed by a few in government and policy, Ashley White sees her new position as ALS Director of Communications as a perfect blend of it all. “I’m thrilled to be back in a research environment, since I started out my career as a researcher and loved being in the lab,” she says. “When I walk around the ALS and see all the tin foil and the beamline equipment, it feels like home.” Read more »

A Designed Protein Maps Brain Activity

A team of scientists designed and validated via x-ray crystallographic studies a fluorescent protein (CaMPARI) that allows the permanent marking of active brain cells. The protein was then used to study live changes via fluorescence in the active nerve cells in brains of fruit flies, zebrafish, and mice. Read more »PPT-icon-35 PDF-icon-35

Misfolded opsin mutants display elevated β-sheet structure

Mutations in rhodopsin can cause misfolding and aggregation of the receptor, which leads to retinitis pigmentosa, a progressive retinal degenerative disease. Förster resonance energy transfer (FRET) and Fourier transform infrared (FTIR) microspectroscopy were utilized to probe within cells the structures formed by G188R and P23H opsins. Read more »

Signal Speed in Nanomagnetic Logic Chains

A time-resolved x-ray imaging technique directly observes signal propagation dynamics in nanomagnetic logic (NML) chains. The technique can assess NML reliability on fast time scales and help optimize chain engineering for this promising ultralow-power computing architecture. Read more »PPT-icon-35 PDF-icon-35
