First direct evidence that a phase of matter competes with high-temperature superconductivity
Scientists have found the first direct evidence that a mysterious phase of matter known as the 'pseudogap' competes with high-temperature superconductivity, robbing it of electrons that otherwise might pair up to carry current through a material with 100 percent efficiency.

Crown ethers flatten in graphene for strong, specific binding
A team led by the Department of Energy's Oak Ridge National Laboratory has discovered a way to dramatically increase the selectivity and binding strength of crown ethers by incorporating them within a rigid framework of graphene. Strong, specific electrostatic binding of crown ethers may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.

Is the Higgs Boson a piece of the matter-antimatter puzzle?
Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some -- but not all -- of the imbalance between matter and antimatter in the universe. Now a SLAC theorist and his colleagues have laid out a possible method for determining if the Higgs boson is involved.

Rattled atoms mimic high-temperature superconductivity
An experiment at the Department of Energy's SLAC National Accelerator Laboratory provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity -- a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.

Optimized algorithms boost combustion research
Turbulent combustion simulations, used in the design of more fuel-efficient combustion systems, have gotten their own efficiency boost, thanks to researchers from Berkeley Lab's Computational Research Division. They developed new algorithmic features that streamline turbulent flame simulations, which are commonly used in the design of combustion systems such as diesel engines; after testing the enhanced code on NERSC supercomputers, they were able to achieve dramatic improvements in simulation times, which will help reduce the time -- and thus the cost -- of designing new engines.

Berkeley Lab algorithms help researchers understand dark energy
To unlock the mystery of dark energy and its influence on the universe, researchers must rely on indirect observations -- watching how fast Type Ia supernovae recede from us as the universe expands. The process of identifying and tracking these objects requires scientists to scrupulously monitor the night sky for slight changes, a task that would be tedious and time-consuming for the Dark Energy Survey without novel tools developed by Berkeley Lab and UC Berkeley researchers.

Atomic trigger shatters mystery of how glass deforms
A new study at the Department of Energy's Oak Ridge National Laboratory, published Sept. 24 in Nature Communications, has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. The study improves understanding of glassy deformation and may accelerate broader application of metallic glass, a moldable, wear-resistant, magnetically exploitable material that is thrice as strong as the mightiest steel and ten times as springy.

Fermilab's 500-mile neutrino experiment up and running
It's the most powerful accelerator-based neutrino experiment ever built in the United States, and the longest-distance one in the world. It's called NOvA, and after nearly five years of construction, scientists are now using the two massive detectors -- placed 500 miles apart -- to study one of nature's most elusive subatomic particles.

Breakthrough: Nanote creates more electron beam than large laser system
A collaboration led by RadiaBeam Technologies, a California-based technology firm actively involved in accelerator R&D, is designing an electron beam source that doesn't need a laser. The team led by Luigi Faillace, a scientist at RadiaBeam, is testing a carbon nanotube cathode -- about the size of a nickel -- in Fermilab's High-Brightness Electron Source Lab that completely eliminates the need for a room-sized laser system currently used to generate the electron beam.
