Physical Review Letters Nickel-78 is a 'doubly magic' isotope, supercomputing calculations confirm
'Doubly magic' atomic nuclei have greater stability than their neighbors thanks to having shells that are fully occupied by both protons and neutrons. Theoretical physicists at Oak Ridge National Laboratory recently used Titan, America's most powerful supercomputer, to compute the nuclear structure of nickel-78 and found that this neutron-rich nucleus is indeed doubly magic. The results may improve understanding of the origin, organization and interactions of stable matter.

Geophysical Review Letters How this Martian moon became the 'Death Star'
For the first time, physicists at LLNL have demonstrated how an asteroid or comet impact could have created Stickney crater without destroying Phobos completely. The research, which also debunks a theory regarding the moon's mysterious grooved terrain, was published in Geophysical Review Letters.
Public Release: 11-Oct-2016 NREL to lead one exascale computing project, support three others
Scientists at the Energy Department's National Renewable Energy Laboratory will lead an effort to model the complex and turbulent flow of wind through large wind plants as part of DOE's Exascale Computing Project, which is gearing up US computational capabilities to prepare for the next generation of supercomputers. NREL will also provide support to three projects related to combustion science, urban systems, and power grid dynamics.

Public Release: 11-Oct-2016 NREL supercomputing model provides insights from higher wind and solar generation in the eastern power grid
A new study from the United States Department of Energy's National Renewable Energy Laboratory used high-performance computing capabilities and innovative visualization tools to model, in unprecedented detail, how the power grid of the eastern United States could operationally accommodate higher levels of wind and solar photovoltaic generation. The analysis considered scenarios of up to 30 percent annual penetration of wind and solar.

IEEE/ACM Transactions on Computational Biology and Bioinformatics Brain modulyzer provides interactive window into the brain
A new tool developed at Berkeley Lab allows researchers to interactively explore the hierarchical processes that happen in the brain when it is resting or performing tasks. Scientists also hope that the tool can shed some light on how neurological diseases like Alzheimer's spread throughout the brain.

Physical Review A Sensors -- quantum leap
By exploiting some exotic quantum states, researchers have conceptually designed a sensor that features unparalleled sensitivity. In a paper published in Physical Review A, Ali Passian of Oak Ridge National Laboratory and George Siopsis of the University of Tennessee describe a photon-sensing scheme for a detector that would behave much like a miniature trampoline.
Public Release: 4-Oct-2016 ORNL licenses rare earth magnet recycling process to Momentum Technologies
The Department of Energy's Oak Ridge National Laboratory and Momentum Technologies have signed a non-exclusive licensing agreement for an ORNL process designed to recover rare earth magnets from used computer hard drives.
The patent-pending process developed as part of DOE's Critical Materials Institute is designed to economically recover large amounts of magnets made using neodymium--a rare earth element that is mined outside the United States.

Proceedings of the National Academy of Sciences A cooperative way to make ammonia
A better understanding of how bacteria fix nitrogen gas into nitrogen-carrying ammonia could lead to energy savings in industrial processes. Researchers are studying the bacterial enzyme that does this, a complicated enzyme called nitrogenase. In new work, researchers discovered that the two sides of nitrogenase cooperate in producing ammonia, alternating through different steps in a way that makes efficient use of the complex enzyme.

Nanoscale Electron beam microscope directly writes nanoscale features in liquid with metal ink
Scientists at the Department of Energy's Oak Ridge National Laboratory are the first to harness a scanning transmission electron microscope to directly write tiny patterns in metallic 'ink,' forming features in liquid that are finer than half the width of a human hair. The automated process is controlled by weaving a STEM instrument's electron beam through a liquid-filled cell to spur deposition of metal onto a silicon microchip. The patterns created are nanoscale.
