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.

Public Release: 7-Aug-2017 The good, the bad and the algae
Sandia National Laboratories is testing whether one of California's largest and most polluted lakes can transform into one of its most productive and profitable. Southern California's 350-square-mile Salton Sea has well-documented problems related to elevated levels of nitrogen and phosphorus from agricultural runoff. Sandia intends to harness algae's penchant for prolific growth to clean up these pollutants and stop harmful algae blooms while creating a renewable, domestic source of fuel.

Weather and Climate Extremes 'Hindcasting' study investigates the extreme 2013 Colorado flood
Using a publicly available climate model, Berkeley Lab researchers 'hindcast' the conditions that led to the Sept. 9-16, 2013 flooding around Boulder, Colo. and found that climate change attributed to human activity made the storm much more severe than would otherwise have occurred.

Public Release: 18-Jul-2017 3-D models help scientists gauge flood impact
Using one of the world's most powerful supercomputers, a University of Iowa team performed one of the first highly resolved, 3-D, volume-of-fluid Reynolds-averaged Navier-Stokes (RANS) simulations of a dam break in a natural environment. The simulation allowed the team to map precise water levels for actual flood events over time.

Nature Communications Researchers ID new mechanism for keeping DNA protein in line
Electrostatic forces known as phosphate steering help guide the actions of an enzyme called FEN1 that is critical in DNA replication and repair, finds a new study led by Berkeley Lab researchers. The findings help explain how FEN1 distinguishes which strands of DNA to target, revealing key details about a vital process in healthy cells as well as providing new directions for cancer treatment research.

Scientific Reports What's on your skin? Archaea, that's what
It turns out your skin is crawling with single-celled microorganisms -- and they're not just bacteria. A study by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Medical University of Graz has found that the skin microbiome also contains archaea, a type of extreme-loving microbe, and that the amount of it varies with age.

Proceedings of the National Academy of Sciences 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.

Nature Researchers find new mechanism for genome regulation
The mechanisms that separate mixtures of oil and water may also help the organization of a part of our DNA called heterochromatin, according to a new Berkeley Lab study. Researchers found that liquid-liquid phase separation helps heterochromatin organize large parts of the genome into specific regions of the nucleus. The work addresses a long-standing question about how DNA functions are organized in space and time, including how genes are silenced or expressed.

Proceedings of the National Academy of Sciences Researchers find a surprise just beneath the surface in carbon dioxide experiment
An X-ray technique, coupled with theoretical work, revealed how oxygen atoms embedded very near the surface of a copper sample had a more dramatic effect on the early stages of the reaction with carbon dioxide (CO2) than earlier theories could account for. This information could prove useful in designing new types of materials to further enhance reactions and make them more efficient in converting carbon dioxide into liquid fuels and other products.
