Electrons Slowing Down at Critical Moments

In a new study, researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory have determined that electrons in some oxides can experience an “unconventional slowing down” of their response to a light pulse.

Extracting Signals of Elusive Particles from Giant Chambers Filled with Liquefied Argon

A revolutionary new kind of neutrino detector, designed in part by scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, sits at the heart of the MicroBooNE experiment at DOE’s Fermi National Accelerator Laboratory (Fermilab). In two new papers, the MicroBooNE collaboration describes how they use this detector to pick up the telltale signs of neutrinos. The papers include details of the signal processing algorithms that are critical to accurately reconstruct neutrinos’ subtle interactions with atoms in the detector.

SLAC’s Ultra-High-Speed ‘Electron Camera’ Catches Molecules at a Crossroads

An extremely fast “electron camera” at the Department of Energy’s SLAC National Accelerator Laboratory has produced the most detailed atomic movie of the decisive point where molecules hit by light can either stay intact or break apart. The results could lead to a better understanding of how molecules respond to light in processes that are crucial for life, like photosynthesis and vision, or that are potentially harmful, such as DNA damage from ultraviolet light.

ALCF Hands-on Workshop Connects Researchers with HPC Experts

For three days this May, more than 40 researchers visited the Argonne Leadership Computing Facility (ALCF), a U.S. Department of Energy (DOE) Office of Science User Facility, to improve the performance of their computational science codes by working alongside the experts who know the facility’s supercomputers best.

Meet Claire Lee: Particle Physicist and Non-Traditional Science Communicator

Lee, who is from South Africa, is a postdoctoral research associate at the U.S. Department of Energy’s Brookhaven National Laboratory. She works on the ATLAS experiment, one of seven particle detector experiments analyzing data from collisions of particles such as protons and lead ions at the Large Hadron Collider (LHC) in Europe.

X-Ray Experiment Confirms Theoretical Model for Making New Materials

Experiments at the Department of Energy’s SLAC National Accelerator Laboratory have confirmed the predictive power of a new computational approach to materials synthesis. Researchers say that this approach, developed at the DOE’s Lawrence Berkeley National Laboratory, could streamline the creation of novel materials for solar cells, batteries and other sustainable technologies.

Fermilab Computing Experts Bolster NOvA Evidence, 1 Million Cores Consumed

The NOvA neutrino experiment, in collaboration with the Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC-4) program and the HEPCloud program at DOE’s Fermi National Accelerator Laboratory, was able to perform the largest-scale analysis ever to support the recent evidence of antineutrino oscillation, a phenomenon that may hold clues to how our universe evolved.

10 Questions for Steven Cowley, New Director of the Princeton Plasma Physics Laboratory

Steven Cowley, a theoretical physicist and international authority on fusion energy, became the seventh Director of the Princeton Plasma Physics Laboratory (PPPL) on July 1 and will be Princeton professor of astrophysical sciences on September 1.

High-School Students Studying Carbon-Based Nanomaterials for Cancer Drug Delivery Visit Brookhaven Lab's Nanocenter

The 11th graders from Islip High School brought the graphene oxide microspheres they made at Stony Brook University to the Center for Functional Nanomaterials for imaging.

New Insights Bolster Einstein’s Idea About How Heat Moves Through Solids

A discovery by scientists at the Department of Energy’s Oak Ridge National Laboratory supports a century-old theory by Albert Einstein that explains how heat moves through everything from travel mugs to engine parts.

New Simulations Break Down Potential Impact of a Major Quake by Building Location and Size

A team from Lawrence Berkeley National Laboratory (Berkeley Lab) and Lawrence Livermore National Laboratory, both U.S. Department of Energy (DOE) national labs, is leveraging powerful supercomputers to portray the impact of high-frequency ground motion on thousands of representative different-sized buildings spread out across the California region.

DOE Awards $100 Million for Energy Frontier Research Centers

U.S. Secretary of Energy Rick Perry announces $100 million in funding for 42 Energy Frontier Research Centers (EFRCs) to accelerate the scientific breakthroughs needed to strengthen U.S. economic leadership and energy security.
