Nature Biotechnology
Defining standards for genomes from uncultivated microorganisms
As genomic data production has ramped up over the past two decades and is being generated on various platforms around the world, scientists have worked together to establish definitions for terms and data collection standards that apply across the board. In Nature Biotechnology, an international team led by DOE JGI researchers has developed standards for the minimum metadata to be supplied with single amplified genomes and metagenome-assembled genomes submitted to public databases.

Bright thinking leads to breakthrough in nuclear threat detection science
Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators -- objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America's ports and borders.

Microbe mystery solved: What happened to the Deepwater Horizon oil plume
The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 is one of the most studied spills in history, yet scientists haven't agreed on the role of microbes in eating up the oil. Now a research team at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has identified all of the principal oil-degrading bacteria as well as their mechanisms for chewing up the many different components that make up the released crude oil.

Study sheds light on how bacterial organelles assemble
Scientists at Berkeley Lab and Michigan State University are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle's protein shell. This work could benefit research in bioenergy and pathogenesis, and it could lead to new methods of bioengineering bacteria for beneficial purposes.

Uncovered: 1,000 new microbial genomes
US Department of Energy Joint Genome Institute scientists have taken a decisive step forward in uncovering the planet's microbial diversity. In Nature Biotechnology, they report the release of 1,003 phylogenetically diverse bacterial and archaeal reference genomes -- the single largest release to date. The DOE is interested in learning more about this biodiversity because microbes play important roles in regulating Earth's biogeochemical cycles and uncovering gene functions and metabolic pathways has wide applications.

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.

Neutrons provide the first nanoscale look at a living cell membrane
A research team from the Department of Energy's Oak Ridge National Laboratory has performed the first-ever direct nanoscale examination of a living cell membrane. In doing so, it also resolved a long-standing debate by identifying tiny groupings of lipid molecules that are likely key to the cell's functioning.

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.

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.

Cryo-electron microscopy achieves unprecedented resolution using new computational methods
Cryo-electron microscopy (cryo-EM)--which enables the visualization of viruses, proteins, and other biological structures at the molecular level--is a critical tool used to advance biochemical knowledge. Now Berkeley Lab researchers have extended cryo-EM's impact further by developing a new computational algorithm instrumental in constructing a 3-D atomic-scale model of bacteriophage P22 for the first time.

Plants at the pump
Regular, unleaded or algae? That's a choice drivers could make at the pump one day. Toward that goal, Sandia National Laboratories is testing strains of algae for resistance to a host of predators and diseases, and learning to detect when an algae pond is about to crash.

Microbiomes more in flux in patients with inflammatory bowel disease
Patients with inflammatory bowel disease are more likely to see dramatic shifts in the make-up of the community of microbes in their gut than healthy people, according to the results of a study published in Nature Microbiology. The results help physicians and scientists understand the disease more fully and potentially offer new ways to track the disease and monitor patients.

Vitamin B12: Power broker to the microbes
In the microbial world, vitamin B12 is a hot commodity. It turns out that vitamin B12, a substance produced by only a few organisms but needed by nearly all of them, wields great power in microbial communities -- ubiquitous structures that affect energy and food production, the environment, and human health.

Seeking structure with metagenome sequences
In the Jan. 20, 2017 issue of Science, a team led by University of Washington's David Baker in collaboration with DOE Joint Genome Institute researchers reports that structural models have been generated for 12 percent of the protein families that had previously had no structural information available. The Baker lab's protein structure prediction server Rosetta analyzed the metagenomic sequences publicly available on the Integrated Microbial Genomes (IMG) system run by the DOE JGI.

Tracking Antarctic adaptations in diatoms
In the Antarctic Ocean, large populations of the diatom Fragillariopsis cylindrus dominate the phytoplankton communities. To learn more about how F. cylindrus adapted to its extremely cold environment, a team including DOE Joint Genome Institute researchers conducted a comparative genomic analysis involving three diatoms. The results, reported online January 16, 2017 in Nature, provided insights into the genome structure and evolution of F. cylindrus, as well as this diatom's role in the Southern Ocean.
