White rot fungi's size explained by breadth of gene families involved
Armillaria fungi are among the most devastating fungal pathogens, causing root rot disease in more than 500 plant species found in forests, parks and vineyards. As white rot fungi, they are capable of breaking down all components of plant cell walls, a capability that interests bioenergy researchers. In Nature Ecology & Evolution, an international team analyzed and compared four Armillaria fungal genomes with those of related fungi to better understand the evolution of Armillaria's abilities.

Decoding the origin of heavy elements in the light from a neutron star merger
On Aug. 17, scientists around the globe were treated to near-simultaneous observations by separate instruments: One set of Earth-based detectors measured the signature of a cataclysmic event sending ripples through the fabric of space-time, and a space-based detector measured the gamma-ray signature of a high-energy outburst emanating from the same region of the sky.

International team reconstructs nanoscale virus features from correlations of scattered X-rays
Berkeley Lab researchers contributed key algorithms which helped scientists achieve a goal first proposed more than 40 years ago -- using angular correlations of X-ray snapshots from non-crystalline molecules to determine the 3-D structure of important biological objects.

Exploring the exotic world of quarks and gluons at the dawn of the exascale
As nuclear physicists delve ever deeper into the heart of matter, they require the tools to reveal the next layer of nature's secrets. Nowhere is that more true than in computational nuclear physics. A new research effort led by theorists at DOE's Thomas Jefferson National Accelerator Facility (Jefferson Lab) is now preparing for the next big leap forward in their studies thanks to funding under the 2017 SciDAC Awards for Computational Nuclear Physics.

Tracking the viral parasites of giant viruses over time
In freshwater lakes, microbes regulate the flow of carbon and determine if the bodies of water serve as carbon sinks or carbon sources. Viruses exist amidst all bacteria, usually in a 10-fold excess and include virophages which live in giant viruses and use their machinery to replicate and spread. Reported in Nature Communications, researchers at The Ohio State University and the DOE Joint Genome Institute have effectively doubled the number of known virophages.

Liverwort genes and land plant evolution
The common liverwort is a living link to the transition from marine algae to land plants. In the Oct. 5, 2017 issue of Cell, an international team including researchers at the DOE Joint Genome Institute, analyzed the genome sequence of the common liverwort (Marchantia polymorpha) to identify genes and gene families that were deemed crucial to plant evolution and have been conserved over millions of years and across plant lineages.

Benchmarking computational methods for metagenomes
To tackle assembling metagenomes, then binning these consensus regions into genome bins, and finally conducting taxonomic profiling, analysts around the world have developed an array of different computational tools, but until now there was a lack of consensus on how to evaluate their performance. In Nature Methods, a team including DOE JGI researchers described the results of the Critical Assessment of Metagenome Interpretation (CAMI) Challenge, the first-ever, community-organized benchmarking assessment of computational tools for metagenomes.

New insights into nanocrystal growth in liquid
PNNL researchers have measured the forces that cause certain crystals to assemble, revealing competing factors that researchers might be able to control. The work has a variety of implications in both discovery and applied science. In addition to providing insights into the formation of minerals and semiconductor nanomaterials, it might also help scientists understand soil as it expands and contracts through wetting and drying cycles.
