Nature Microbiology
Fungal enzymes team up to more efficiently break down cellulose
Cost-effectively breaking down bioenergy crops into sugars that can then be converted into fuel is a barrier to commercially producing sustainable biofuels. Bioenergy researchers are looking to fungi for help; collectively, they can break down almost any substance on earth, including plant biomass. Enabled by US Department of Energy Office of Science User Facilities, a team reports for the first time that early lineages of fungi can form enzyme complexes capable of degrading plant biomass.

Physics of Plasmas
New model of plasma stability could help researchers predict and avoid disruptions
PPPL physicists have helped develop a new computer model of plasma stability in doughnut-shaped fusion machines known as tokamaks. The new model incorporates recent findings gathered from related research efforts and simplifies the physics involved so computers can process the program more quickly. The model could help scientists predict when a plasma might become unstable and then avoid the underlying conditions.

Nature Genetics
Finding a new major gene expression regulator in fungi
Changing a single letter, or base, in an organism's genetic code impact its traits. Subtler changes can and do happen: in eukaryotes, one such modification involves adding a methyl group to base 6 of adenine (6mA). In Nature Genetics, researchers report the prevalence of 6mA modifications in the earliest branches of the fungal kingdom. This little-explored realm provides a repertoire of important and valuable gene products for DOE missions in bioenergy and environment.

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.

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.

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.

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.

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.

Story tips from the Department of Energy's Oak Ridge National Laboratory, April 2017
An ORNL-led team is bringing together quantum, high-performance and neuromorphic computing architectures to address complex issues that, if resolved, could clear the way for more flexible, efficient technologies in intelligent computing; ORNL is using electron beam precision to instantly adhere cathode coatings for lithium-ion batteries; ORNL created an approach to get a better look at plant cell wall characteristics at high resolution as they create more efficient, less costly methods to deconstruct biomass.

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.

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.
