In a recent demonstration project, physicists from Brookhaven National Laboratory and Lawrence Berkeley National Laboratory used the Cori supercomputer at the National Energy Research Scientific Computing Center to reconstruct data collected from a nuclear physics experiment, an advance that could dramatically reduce the time it takes to make detailed data available for scientific discoveries.
A team of researchers from ORNL's Energy and Transportation Science Division is using neutron imaging to study particulate filters that collect harmful emissions in vehicles. A better understanding of how heat treatments and oxidation methods can remove layers of soot and ash from these filters could lead to improved fuel-efficiency.
Forty-five years ago this month, a telescope tucked inside a 14-story, 500-ton dome atop a mile-high peak in Arizona took in the night sky for the first time and recorded its observations on glass photographic plates. Today, the dome closes on the previous science chapters of the 4-meter Nicholas U. Mayall Telescope and starts preparing for its new role in creating the largest 3-D map of the universe.
Scientists working on the ATLAS experiment at the Large Hadron Collider (LHC) have precisely measured the mass of the W boson, a particle that plays a weighty role in a delicate balancing act of the quantum universe. This measurement is regarded as one of the most difficult in particle physics and the first of its kind for an LHC experiment.
Twenty-four teams from 16 Bay Area high schools faced off Feb. 3 in the SLAC Regional DOE Science Bowl, a series of fast-paced question-and-answer matches that test knowledge in biology, chemistry, physics, earth and space sciences, energy and math. The competition is hosted annually by the Department of Energy's SLAC National Accelerator Laboratory.
Without fungi, dead trees wouldn't decay. The short-order cooks of the natural world, certain types of fungi can decompose plant cell walls and deposit carbon back in the soil. Scientists supported by the Department of Energy's Office of Science are investigating these processes and how we may be able to use them to make biofuels production cheaper and more efficient.
With a symposium on fundamental physics, the Department of Energy's SLAC National Accelerator Laboratory remembered one of its key figures: world-renowned theoretical physicist Sidney Drell, who passed away in December 2016. Nearly 200 guests attended the Jan. 12 event to celebrate Drell's numerous scientific contributions, which continue to have a tremendous impact on our understanding of the subatomic world.
Beginning college as a 40-year-old might be considered a disadvantage, but US Department of Energy National Renewable Energy Laboratory (NREL) researcher Dave Moore didn't see it that way. Instead, he thinks it gave him an edge, starting as a seasoned freshman at the University of Washington.
Scientists at the Department of Energy's SLAC National Accelerator Laboratory have discovered a way to triple the amount of power generated by the world's most powerful X-ray laser. The new technique, developed at SLAC's Linac Coherent Light Source (LCLS), will enable researchers to observe the atomic structure of molecules and ultrafast chemical processes that were previously undetectable at the atomic scale.
Elke-Caroline Aschenauer, a senior physicist at Brookhaven National Laboratory, has been awarded a Humboldt Research Award for her contributions to the field of experimental nuclear physics. Opportunities made possible by this award will help to foster or strengthen collaborations among European and US physicists addressing some of the major research aims at Brookhaven's Relativistic Heavy Ion Collider, as well as among those hoping to build a US-based Electron-Ion Collider (EIC).
Scientists at the Department of Energy's SLAC National Accelerator Laboratory are using X-ray light to observe and understand how the process of making metal parts using three-dimensional (3-D) printing can leave flaws in the finished product -- and discover how those flaws can be prevented.
In the last few years, researchers at Berkeley Lab, UC Davis and University of Stavanger in Norway have developed a new protocol, called BChain, which makes private blockchain even more robust. The researchers are also working with colleagues at Berkeley Lab and beyond to adapt this tool to support applications that are of strategic importance to the Department of Energy's Office of Science.
Scientists at the Department of Energy's SLAC National Accelerator Laboratory have seen for the first time how atoms in iron-platinum nanoparticles -- a next-generation material for magnetic data storage devices -- respond extremely rapidly to brief laser flashes. Understanding these fundamental motions could potentially lead to new ways of manipulating and controlling such devices with light.
A team at Berkeley Lab has designed, built, and delivered a unique version of a device, called an injector gun, that can produce a steady stream of these electron bunches. The gun will be used to produce brilliant X-ray laser pulses at a rapid-fire rate of up to 1 million per second.
The ProtoDUNE project is building two smaller-scale detectors as a test bed for the Deep Underground Neutrino Experiment, hosted by Fermi National Accelerator Laboratory. But even these smaller detectors are enormous and complex.
Paul Dabbar, the Department of Energy Under Secretary for Science, visited SLAC National Accelerator Laboratory Jan. 17 for a day of tours and discussions on how the lab is driving scientific innovation. His visit included meetings with SLAC and Stanford leadership, as well as researchers and scientists involved in the lab's X-ray science, particle physics and astrophysics, technology innovation and applied energy programs.
Argonne's Cyber Fed Model provides a community-based system for near-real-time dissemination of cyberthreat indicators, defensive measures, and tools to simplify use of this information. Once the system detects an attack, it rapidly repairs the local damage while also preventing its spread.
Argonne's Education department partnered with the U.S. Department of Energy's Fermi National Accelerator Laboratory and the University of Chicago and sent 50 scientists to Chicago area schools in December as part of the global Hour of Code.
Two scientists with the US Department of Energy's (DOE) Argonne National Laboratory have been named to the Web of Science's Highly Cited List of 2017, ranking in the top 1 percent of their peers by citations and subject area. Materials Scientist Khalil Amine and Energy and Environmental Policy Scientist David Streets say they are thrilled to see their work -- and the laboratory -- recognized in such a way.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
