Science For first time, researchers measure forces that align crystals and help them snap together
For the first time, researchers have measured the force that draws tiny crystals together and visualized how they swivel and align. Called van der Waals forces, the attraction provides insights into how crystals self-assemble, an activity that occurs in a wide range of cases in nature, from rocks to shells to bones.

International Conference on Mathematics & Computational Methods to Nuclear Science & Engineering Predictive power
The Consortium for Advanced Simulation of Light Water Reactors carried out the largest time-dependent simulation of a nuclear reactor ever to support Tennessee Valley Authority and Westinghouse Electric Company during the startup of Watts Bar Unit 2, the first new US nuclear reactor in 20 years. The simulation was carried out primarily on Oak Ridge Leadership Computing Facility resources.

Nature Materials Tweaking a molecule's structure can send it down a different path to crystallization
Silky chocolate, a better medical drug, or solar panels all require the same thing: just the right crystals making up the material. Now, scientists trying to understand the paths crystals take as they form have been able to influence that path by modifying the starting ingredient.

Proceedings of the National Academy of Sciences Advantage: Water
When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the slightest advantage, like the score in a highly competitive tennis game.

Science Discovered: Novel group of giant viruses
Viruses are thought to outnumber the microbes on Earth; both outnumber the stars in the Milky Way. A handful of giant viruses have been discovered in the past two decades, and in Science, DOE Joint Genome Institute scientists report a novel group of giant viruses with a more complete set of translation machinery genes than any other virus known to date. They believe that this discovery significantly increases our understanding of viral evolution.

Nature Communications Built from the bottom up, nanoribbons pave the way to 'on-off' states for graphene
A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the material. 'Confinement changes graphene's behavior,' said An-Ping Li, a physicist at the Department of Energy's Oak Ridge National Laboratory.

Genome Biology Revealing Aspergillus diversity for industrial applications
In a Feb. 14, 2017 study published in Genome Biology, an international team report sequencing the genomes of 10 novel Aspergillus species, which were compared with the eight other sequenced Aspergillus species. With this first ever genus-wide view, the international consortium found that Aspergillus has a greater genomic and functional diversity than previously understood, broadening the range of potential applications for the fungi considered one of the most important workhorses in the biotechnology.
