In April 2026, a panel of vibe coders hosted a tutorial at the ALS. From a general overview to specific strategies to optimize the code, participants learned all about how vibe coding can improve their workflows. Read more »
Seeing Double: Dual Measurements of Ceria Provide Insights for Catalysis
In a recent study at the ALS, researchers employed an approach that combines two techniques and uses a single X-ray beam to capture both chemical and structural changes in nanopatterned ceria during catalytic reactions. Read more »
Multiscale X-Ray Measurements Reveal How Stretchable Polymer Semiconductors Dissipate Stress
Using multimodal, in situ measurements at the ALS, researchers uncovered a two-stage process for how stretchable polymer semiconductors adapt their structure during stretching. The findings establish a multiscale design framework for conjugated polymers used in stretchable electronic devices. Read more »

Accelerate UX Workshop Brings Global Expertise Together at the ALS
Staff from eleven different accelerator lab facilities gathered at the ALS to improve the user experience for operators, researchers, engineers, and more. Workshop participants learned from experts in the UX field and even took part in a hackathon that paired beamline scientists with interface developers. Read more »
Strength in Numbers: Nanopatterns Amplify X-Ray Signals from Buried Interfaces
Berkeley Lab researchers developed a new x-ray technique that uses nanoscale patterns to amplify weak signals, allowing scientists to observe chemical reactions at buried solid–liquid interfaces that were previously challenging to study. Read more »
Aerosol Chemistry Offers Clues to the Arctic’s Future
Researchers used scanning transmission x-ray microscopy to analyze Arctic aerosols, which strongly influence cloud formation and overall climate. Understanding what these particles are and how they change as they travel could help improve climate models and yield more accurate predictions of the changing Arctic environment’s global impact.
