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.
In some of the coldest places in the world, scientists supported by the Department of Energy's Office of Science are studying how permafrost thaws. Using both field and laboratory data, these researchers are collaborating with modelers to improve our understanding of future climate change.
14-Jun-2017 New research finds a missing piece to high-temperature superconductor mystery
An international team led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University has detected new features in the electronic behavior of a copper oxide material that may help explain why it becomes a perfect electrical conductor -- a superconductor -- at relatively high temperatures.
8-Jun-2017 Tackling infectious disease -- one protein at a time
A team of scientists in the Pacific Northwest has solved the 3-D structure of 1,000 proteins from more than 70 organisms that cause infectious disease in people. The proteins the team has studied come from microbes that cause several serious diseases, including tuberculosis, Listeria, Giardia, Ebola, anthrax, C. diff., Legionella, Lyme, chlamydia and the flu.
7-Jun-2017 Q&A: SLAC's Vera Lüth discusses the search for new physics
In this Q&A, particle physicist Vera Lüth discusses scientific results that potentially hint at physics beyond the Standard Model. The professor emerita of experimental particle physics at the Department of Energy's SLAC National Accelerator Laboratory is co-author of a review article published today in Nature that summarizes the findings of three experiments: BABAR at SLAC, Belle in Japan and LHCb at CERN.
1-Jun-2017 SLAC X-ray beam helps uncover blueprint for Lassa virus vaccine
A team of scientists from The Scripps Research Institute (TSRI) has solved the structure of the viral machinery that Lassa virus uses to enter human cells. X-ray beams from the Stanford Synchrotron Radiation Lightsource (SSRL) at the Department of Energy's SLAC National Accelerator Laboratory gave the team the final piece in a puzzle they sought to solve for over 10 years.
19-May-2017 A fresh math perspective opens new possibilities for computational chemistry
A new mathematical "shortcut" developed by Berkeley Lab researchers is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours. These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year.
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.
