Powering Science: How SYNAPS-I Builds on Meta’s Open Source AI

SYNAPS-I, a DOE initiative led by Berkeley Lab, unites 60 researchers across five labs to speed up X-ray and neutron data analysis using AI. Because prepublication data must stay on secure government systems, open-source models from Meta — SAM 3 and DINOv3 — let the team fine-tune cutting-edge AI entirely in-house. Read more »

The ALS-U Project Progresses with New Director

The Advanced Light Source Upgrade (ALS-U) project has received approval for a revised cost and schedule, targeting completion by late 2029. Greg Hays joins the team to steer the historic modernization project, which will increase soft X-ray brightness a hundredfold and enable AI-driven research in materials science, quantum computing, biology, and more.
