Berkeley Lab
Bringing Science Solutions to the World

ALS COVID status update. Visit this link for user-related information. See here for staff-only information.

The Advanced Light Source is a Department of Energy-funded synchrotron facility that provides users from around the world access to the brightest beams of soft x-rays, together with hard x-rays and infrared, for scientific research and technology development in a wide range of disciplines.

How Proteins Remodel DNA in Bacteria under Stress

Multiscale, multimodal visualization techniques at the ALS enabled researchers to clarify how proteins remodel bacterial DNA in response to stressful environments. The discovery could lead to new strategies for controlling microbial behavior and, eventually, new ways to fight bacterial infections. Read more »PPT-icon-35 PDF-icon-35

Eric Gullikson Receives 2020 Klaus Halbach Award

When Eric Gullikson first arrived at Berkeley Lab, the Advanced Light Source (ALS) did not yet exist. Thanks to his work, not only has the ALS grown in scale, capability, and renown, but other light sources worldwide have benefited as well. The ALS Users’ Executive Committee recognized Gullikson, staff scientist, for “contributions to x-ray metrology that are central to building beamlines at the ALS and around the world.” Read more »

Missing Lysine Link Could Improve Plant-Based Nutrition

To engineer crops with higher levels of the important amino acid, lysine, researchers solved the structure of an enzyme that helps break down lysine in plants. A fuller understanding of the factors affecting lysine levels should aid in the successful development of stable high-lysine crops to combat malnutrition globally. Read more »

2020 ALS User Meeting Highlights

An experiment born of necessity, the 2020 ALS User Meeting was held August 25–28, “in silico.” The results have been generally positive, revealing emergent benefits to interactions occurring in the virtual realm, even as we hope for a return to real space ASAP. Read more »

Small but Still Mighty: Ultrafine Grains Produce Ultrastrong Metals

Researchers used in situ high-pressure diffraction to resolve a debate about whether a metal’s strength increases or decreases when its grain size decreases below a critical point. The results indicate that ultrastrong metals for future applications can indeed be achieved through grain-size refinement and grain-boundary engineering. Read more »
