Science, technology and national security come together in a personal and powerful way through the US Air Force Fellows program at Argonne National Laboratory, which on July 10 will become a second home to Lt. Col. Chris Snyder and Maj. Sean 'Skeet' Richardson.
A new era in international particle physics research officially began July 21 with a unique groundbreaking held a mile underground at the Sanford Underground Research Facility in South Dakota. Dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE).
Nature provides myriad examples of unique materials and structures developed for specialized applications or adaptations. An interdisciplinary group of researchers at the US Department of Energy's Ames Laboratory is trying to unlock the secrets that organisms use to build such complex structures so that power can be used to create materials not found in nature and not capable of being synthesized by conventional means.
17-Jul-2017 No assembly required: Nanoparticles that put themselves together
Scientists may be able to use self-assembly to design new materials with custom characteristics. Understanding self-assembly is particularly important for working with nanoparticles. Scientists supported by the Department of Energy are investigating two major methods of self-assembly. They are looking into both particles that assemble on their own as well as 'nano-Velcro' that can pull together particles that wouldn't otherwise connect on their own.
12-Jul-2017 Tackling disease in three dimensions: Supercomputers help decode RNA structure
In collaboration with staff from the Argonne Leadership Computing Facility, researchers at the National Cancer Institute have perfected a technique that accurately computes the 3-D structure of RNA sequences. This method, which relies on a computer program known as RS3D and supercomputer Mira gives researchers studying cancer and other diseases structural insights about associated RNAs that can be used to advance computer-assisted drug design and development.
In a milestone for studying a class of chemical reactions relevant to novel solar cells and memory storage devices, an international team of researchers working at the Department of Energy's SLAC National Accelerator Laboratory used an X-ray laser to watch 'molecular breathing' -- waves of subtle in-and-out motions of atoms -- in real time and unprecedented detail.
6-Jul-2017 ORNL researchers apply imaging, computational expertise to St. Jude research
In the quest to better understand and cure childhood diseases, scientists at St. Jude Children's Research Hospital accumulate enormous amounts of data from powerful video microscopes. To help St. Jude scientists mine that trove of data, researchers at Oak Ridge National Laboratory have created custom algorithms that can provide a deeper understanding of the images and quicken the pace of research.
5-Jul-2017 Will brain-inspired chips make a dent in science's big data problems?
Although neuromorphic computing is still in its infancy, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers hope that these tiny, low-power, brain-inspired computing systems could one day help alleviate some of science's big data challenges. With funding from the Laboratory Directed Research and Development (LDRD) program, two groups of researchers are exploring how science might benefit from this new technology.
30-Jun-2017 Ecological roots
Despite popular conceptions as an offshoot of the environmental movement, much of the field of ecology evolved to meet the needs of the federal government during the Atomic Age. The Department of Energy's national laboratories played a key role, from developing fundamental theories to computer models. The contributions from the institutions that became Savannah River Ecology Laboratory, Oak Ridge National Laboratory, and Pacific Northwest National Laboratory still influence the field today.
27-Jun-2017 Yi Cui named Blavatnik National Laureate
Pioneering nanoscientist Yi Cui, professor of materials science and engineering at Stanford University and of photon science at the Department of Energy's SLAC National Accelerator Laboratory, has been named a 2017 Blavatnik National Laureate. The $250,000 award recognizes the most promising researchers age 42 and younger at top US academic and research institutions.
23-Jun-2017 World's biggest neutrino experiment moves one step closer
On June 21, a prototype detector at CERN for the Deep Underground Neutrino Experiment recorded its first particle tracks. So begins the largest ever test of an extremely precise method for measuring elusive particles called neutrinos, which may hold the key to why our universe looks the way it does and how it came into being.
22-Jun-2017 Our expanding universe: Delving into dark energy
The universe is stretching out ever more rapidly -- a phenomena known as cosmic acceleration -- and scientists don't know why. Understanding the "dark energy" that is causing this expansion would help them put together a clearer picture of the universe's history. Scientists supported by the Department of Energy's Office of Science are using massive telescopes to chart how dark energy has influenced the structure of the universe over time.
22-Jun-2017 A single electron's tiny leap sets off 'molecular sunscreen' response
In experiments at the Department of Energy's SLAC National Accelerator Laboratory, scientists were able to see the first step of a process that protects a DNA building block called thymine from sun damage: When it's hit with ultraviolet light, a single electron jumps into a slightly higher orbit around the nucleus of a single oxygen atom.
21-Jun-2017 Upgrades at Sandia Lab's Tonopah Test Range help weapons testing
It's been a challenge for Sandia National Laboratories' Tonopah Test Range to keep decades-old equipment running while gathering detailed information required for 21st century non-nuclear testing. Over the past several years, the Nevada range changed the analog brains in instruments to digital, moved to modern communications systems and upgraded telemetry and tracking equipment and computing systems.
20-Jun-2017 Chicago Quantum Exchange to create technologically transformative ecosystem
The University of Chicago is collaborating with the US Department of Energy's Argonne National Laboratory and Fermi National Accelerator Laboratory to launch an intellectual hub for advancing academic, industrial and governmental efforts in the science and engineering of quantum information.
20-Jun-2017 SLAC experiment is first to decipher atomic structure of an intact virus with an X-ray laser
An international team of scientists has for the first time used an X-ray free-electron laser to unravel the structure of an intact virus particle on the atomic level. The method dramatically reduces the amount of virus material required, while also allowing the investigations to be carried out several times faster than before. This opens up entirely new research opportunities.
16-Jun-2017 With ARM instruments watching, an extensive summer melt in west Antarctica
One day in December of 2015, bound for a remote ice camp in the interior of Antarctica, Scripps Institution of Oceanography doctoral student Ryan Scott boarded a ski-equipped LC-130 turboprop transport plane at McMurdo Station at the south tip of Ross Island. It was austral summer and the temperature outside hovered around -4 degrees Celsius.
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.
