X-rays reveal 'handedness' in swirling electric vortices
Scientists used spiraling X-rays at Berkeley Lab to observe, for the first time, a property that gives left- or right-handedness to swirling electric patterns -- dubbed polar vortices -- in a layered material called a superlattice.

All in the family: Focused genomic comparisons
Aspergillus fungi are pathogens, decomposers, and important sources of biotechnologically-important enzymes. In the Proceedings of the National Academy of Sciences, a team led by researchers at the Technical University of Denmark, the DOE Joint Genome Institute and the Joint BioEnergy Institute report the first outcome from the large-scale sequencing of 300+ Aspergillus species. These findings are a proof of concept of novel methods to functionally annotate genomes to more quickly identify genes of interest.

Breaking bad metals with neutrons
By combining the latest developments in neutron scattering and theory, researchers are close to predicting phenomena like superconductivity and magnetism in strongly correlated electron systems. It is likely that the next advances in superconductivity and magnetism will come from such systems, but they might also be used in completely new ways such as quantum computing.

ORNL researchers use Titan to accelerate design, training of deep learning networks
For deep learning to be effective, existing neural networks to be modified, or novel networks designed and then 'trained' so that they know precisely what to look for and can produce valid results. This is a time-consuming and difficult task, but one that a team of ORNL researchers recently demonstrated can be dramatically expedited with a capable computing system.

Multi-model effort highlights progress, future needs in renewable energy modeling
Models of the US electricity sector are relied upon by sector stakeholders and decision makers, but the recent surge in variable renewable energy (VRE), such as wind and solar, led a team of modeling experts to examine how these models would represent scenarios with high penetrations of VRE.

Surprising result shocks scientists studying spin
Scientists analyzing results of spinning protons striking different sized atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) found an odd directional preference in the production of neutrons that switches sides as the size of the nuclei increases. The results offer new insight into the mechanisms affecting particle production in these collisions.

Real world native biocrusts: Microbial metabolism
Specific compounds are transformed by and strongly associated with specific bacteria in native biological soil crust (biocrust) using a suite of tools called 'exometabolomics.' Understanding how microbial communities in biocrusts adapt to harsh environments could shed light on the roles of soil microbes in the global carbon cycle.

Pioneering smart grid technology solves decades old problematic power grid phenomenon
Sandia National Laboratories and Montana Tech University have demonstrated an R&D 100 award-winning control system that smooths out inter-area oscillations using new smart grid technology in the western power grid. The new system allows utilities to push more electricity through transmission lines, leading to lower costs for utilities and consumers and greater stability for the grid.

Tweaking quantum dots powers-up double-pane solar windows
Researchers at Los Alamos National Laboraotry are creating double-pane solar windows that generate electricity with greater efficiency and also create shading and insulation. It's all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum. The approach complements existing photovoltaic technology by adding high-efficiency sunlight collectors to existing solar panels or integrating them as semitransparent windows into a building's architecture.

New study visualizes motion of water molecules, promises new wave of electronic devices
A novel approach to studying the viscosity of water has revealed new insights about the behavior of water molecules and may open pathways for liquid-based electronics. Oak Ridge National Laboratory used a high-resolution inelastic X-ray scattering technique to measure the strong bond involving a hydrogen atom sandwiched between two oxygen atoms. This hydrogen bond is a quantum-mechanical phenomenon responsible for various properties of water, including viscosity, which determines a liquid's resistance to flow or to change shape.

A catalytic balancing act
Scientists have recently used a new and counterintuitive approach to create a better catalyst that supports one of the reactions involved in splitting water into hydrogen and oxygen. By first creating an alloy of two of the densest naturally occurring elements and then removing one, the scientists reshaped the remaining material's structure so that it better balanced three important factors: activity, stability and conductivity.

When one reference genome is not enough
Having plant pan-genomes for crops that are important for fuel and food applications would enable breeders to harness natural diversity to improve traits such as yield, disease resistance, and tolerance of marginal growing conditions. In Nature Communications, an international team led by researchers at the Joint Genome Institute gauged the size of a plant pan-genome using Brachypodium distachyon, a wild grass widely used as a model for grain and biomass crops.

A functional genomics database for plant microbiome studies
Most of the interaction between microbes and plants occurs at the interface between the roots and soil. In Nature Genetics, a team led by JGI researchers isolated novel bacteria from plant root environments and combined the new genomes with thousands of publicly available genomes representing the major groups of plant-associated bacteria, and bacteria from plant and non-plant environments. Through the resulting database, researchers identified genes enriched in the genomes of plant-associated and root-associated organisms.

Sandia computer modeling aids solder reliability in nuclear weapons
Solder isn't the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability.

New technique could make captured carbon more valuable
Carbon capture could help coal plants reduce emissions if economic challenges can be overcome. Turning captured carbon into a useable product is one solution. Scientists have developed an efficient process for turning captured carbon dioxide into syngas that can be used to make fuels and chemicals. Results were published Dec. 14 by Green Chemistry. "For the first time it was demonstrated that syngas can be directly produced from captured CO2," the researchers wrote.
