X-Rays Recount Origin of Oddball Meteorites

X-ray experiments at Berkeley Lab played a key role in resolving the origin of rare, odd meteorites that have puzzled scientists since their discovery a half-century ago. Known as type IIE iron meteorites, they appear to have originated from a parent body that had a composition featuring both fully melted and unmelted parts – other meteorite types display only one composition.

X-rays size up protein structure at the ‘heart’ of COVID-19 virus

Researchers have performed the first room temperature X-ray measurements on the SARS-CoV-2 main protease—the enzyme that enables the virus to reproduce. It marks an important first step in the ultimate goal of building a comprehensive 3D model of the enzymatic protein that will be used to advance supercomputing simulations aimed at finding drug inhibitors to block the virus’s replication mechanism and help end the COVID-19 pandemic.

Milestone in Advanced Light Source Upgrade Project Will Bring in a New Ring

An upgrade of the Advanced Light Source, a synchrotron at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), has passed an important milestone that will help to maintain the ALS’ world-leading capabilities. On Dec. 23 the DOE granted approval for a key funding step that will allow the project to start construction on a new inner electron storage ring known as an accumulator ring.

AI System Accurately Detects Key Findings in Chest X-Rays of Pneumonia Patients Within 10 Seconds: Study Finds Promise of Faster Treatment

From 20 minutes or more to 10 seconds. Researchers from Intermountain Healthcare and Stanford University say 10 seconds is about how quickly a new system they studied that utilizes artificial intelligence took to accurately identify key findings in chest X-rays of patients in the emergency department suspected of having pneumonia.
