University of Washington researchers discovered that AI models ignored clinically significant indicators on X-rays and relied instead on characteristics such as text markers or patient positioning that were specific to each dataset to predict whether someone had COVID-19.
These news briefs cover topics including gut microbes, tsetse flies in 3D, an energy use framework for heating and cooling, and new gravitational lensing candidates.
A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.
Researchers at the Department of Energy’s Oak Ridge National Laboratory investigated the binding properties of several hepatitis C drugs to determine how well they inhibit the SARS-CoV-2 main protease, a crucial protein enzyme that enables the novel coronavirus to reproduce. Inhibiting, or blocking, the protease from functioning is vital to stopping the virus from spreading in patients with COVID-19.
In a new perspective, SLAC and University of Paderborn scientists argue that research at synchrotrons could help improve water-purifying materials in ways that might not otherwise be possible.
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.
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.
Berkeley Lab’s Advanced Light Source X-ray facility has been recalled to action to support research related to COVID-19, the coronavirus disease that has already infected about 2 million people around the world.
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.
Antonino Miceli is the group leader of the Detectors Group in the X-ray Science Division of the Advanced Photon Source at the U.S. Department of Energy’s Argonne National Laboratory, a senior fellow at the Northwestern Argonne Institute of Science and Engineering, and a senior scientist at the University of Chicago Consortium for Advanced Science and Engineering.
Scientists at Berkeley Lab have demonstrated how a powerful electron microscopy technique can provide direct insight into the performance of any material – from strong metallic glass to flexible semiconducting films – by pinpointing specific atomic “neighborhoods.”
This is part of a continuing profile series on the directors of the Department of Energy (DOE) Office of Science user facilities.
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.
To learn more about the chemical processes in oil paints that can damage aging artwork, a team led by researchers at the National Gallery of Art and the National Institute of Standards and Technology conducted a range of studies that included 3D X-ray imaging of a paint sample at Berkeley Lab’s Advanced Light Source.
Binghamton University, State University of New York will acquire a sophisticated new X-ray tool useful in materials research and R&D for electronics. The $1.75 million system — the third of its kind in the world and the first outside of Europe — will be funded by $1.23 million from the National Science Foundation’s Major Research Instrumentation program and additional money from the campus.
Berkeley Lab scientists participate in the discovery of ognitite; other candidate new-mineral studies in progress Like a tiny needle in a sprawling hayfield, a single crystal grain measuring just tens of millionths of a meter – found in a borehole sample…
