Researchers develop new method to analyze proteins in ecologically significant moss
A type of peat moss has surprised scientists with its climate resilience: Sphagnum divinum is actively speciating in response to hot, dry conditions.
Neutrons see stress in 3D-printed parts, advancing additive manufacturing
Using neutrons to see the additive manufacturing process at the atomic level, scientists have shown that they can measure strain in a material as it evolves and track how atoms move in response to stress.
New study reveals the influence of natural climate drivers on extreme monsoons in Pakistan
A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory looks at some of the influences that could be driving the increasingly severe weather over Pakistan.
Scientists illuminate the mechanics of solid-state batteries
As current courses through a battery, its materials erode over time. Mechanical influences such as stress and strain affect this trajectory, although their impacts on battery efficacy and longevity are not fully understood.
ORNL launches Center for AI Security Research to study AI’s impacts on society, security
The Department of Energy’s Oak Ridge National Laboratory announced the establishment of the Center for AI Security Research, or CAISER, to address threats already present as governments and industries around the world adopt artificial intelligence and take advantage of the benefits it promises in data processing, operational efficiencies and decision-making.
ORNL’s Smoky Mountains Conference returns to in-person in 2023
ORNL hosted its annual Smoky Mountains Computational Sciences and Engineering Conference in person for the first time since the COVID-19 pandemic.
Researchers develop open-source mixed-precision benchmark tool for supercomputers
As Frontier, the world’s first exascale supercomputer, was being assembled at the Oak Ridge Leadership Computing Facility in 2021, understanding its performance on mixed-precision calculations remained a difficult prospect.
OLCF launches new allocation program, SummitPLUS
The Oak Ridge Leadership Computing Facility, a Department of Energy Office of Science user facility at ORNL, is pleased to announce a new allocation program for computing time on the IBM AC922 Summit supercomputer.
Computing conference kicks off with generative AI workshop
The Department of Energy’s Oak Ridge National Laboratory hosted its Smoky Mountains Computational Science and Engineering Conference for the first time in person since the COVID pandemic broke in 2020. The conference, which celebrated its 20th consecutive year, took place at the Crowne Plaza Hotel in downtown Knoxville, Tenn., in late August.
Structural characterization of an intrinsically disordered protein complex using integrated small-angle neutron scattering and computing
Computational scientists and neutron structural biologists from Oak Ridge National Laboratory developed an integrated workflow using small-angle neutron scattering (SANS), atomistic molecular dynamics (MD) simulation, and an autoencoder-based deep learning (DL) algorithm to characterize structural ensembles of intrinsically disordered proteins (IDPs). IDPs make up 33% to 50% of eukaryotic proteomes and are involved in critical cellular function and regulation.
Modeling climate extremes
Researchers from Oak Ridge National Laboratory and Northeastern University modeled how extreme conditions in a changing climate affect the land’s ability to absorb atmospheric carbon — a key process for mitigating human-caused emissions. They found that 88% of Earth’s regions could become carbon emitters by the end of the 21st century.
