Improving Anti-Influenza Medications
Protein crystallography at ALS Beamline 8.3.1 helped scientists understand the M2 proton-channel structure from the influenza A virus, an understanding that is needed to design better anti-influenza medications. Read more »
Cobber Lam, ALS Systems Administrator
Cobber Lam started working at Berkeley Lab 10 years ago as a student assistant, while attending college at Cal State East Bay. Within two months, he was assigned to the ALS and has stayed put ever since. He used to be matrixed via IT, but last year he became a direct ALS employee. ALS IT support is divided between Lam and Tim Kellogg, with Lam being more forward-facing, dealing with users and staff, and Kellogg working on the back-end mostly with controls and operations groups.

Manganese Reduction-Oxidation Drives Plant Debris Decomposition
ALS research has shown that manganese reduction-oxidation (redox) reactions are an important factor in controlling the rate of plant debris decomposition. Understanding the role of manganese will help build better models to predict how litter decomposition rates—and thus nutrient cycling and the ecosystem carbon balance—may behave in future climate scenarios.

Porous-Framework Electrocatalysts Are Key to Carbon Dioxide Conversion
Researchers have made significant headway in the quest to convert CO2 into valuable chemical products such as fuels, pharmaceuticals, and plastics. Recent work at the ALS has shown MOFs and COFs as a valuable new class of CO2 reduction catalysts. Read more »
Call for Proposals to Host Workshops at the 2016 ALS User Meeting
ALS users are invited to submit proposals to host workshops at the upcoming ALS User Meeting to be held October 3-5, 2016 at Berkeley Lab. Students are also encouraged to suggest workshop topics of particular interest to them.

The Phase Transition in VO2 Probed Using X-ray, Visible and Infrared Radiations
The nearly simultaneous Mott (electronic) and Peierls (structural) transitions in vanadium dioxide are of significant scientific interest and have tremendous technological promise in computing, memory, optics, and micromechanics. The cover features nanoscale-resolution maps of the Mott and Peierls transitions imaged simultaneously by Kumar et al. using state-of-the-art in situ STXM at the ALS. Read more »
Aerosol Oxidation Speeds Up in Smoggy Air
To better understand the effects of organic aerosols on climate, pollution, and health, researchers measured aerosol reaction rates at ALS Beamline 9.0.2. They discovered an unexpectedly large acceleration in aerosol oxidation in the presence of anthropogenic pollutants commonly found in smoggy air, a result that could help bring models closer in line with observations.

Improving Meningococcal Vaccines
Scientists have found a way to improve the stability of an essential antigenic protein to develop vaccines with higher efficacy for prevention of bacterial meningitis. Read more »
New Hope for Retinitis Pigmentosa Patients
Using FTIR microspectroscopy at the NSLS in Brookhaven and at ALS Beamline 1.4.3, scientists got a first glimpse into the structural changes that result from point mutations in opsin, one of the causes of retinitis pigmentosa. Read more »
