International Symposium on Ballistics Keeping alive the art of experimental design
A team of Lawrence Livermore National Laboratory (LLNL) researchers was honored with the Neill Griffiths Award this month, recognizing the most significant contribution to shaped charge technology. The award was presented at the annual International Symposium on Ballistics. The research helped solve a challenge Shell International Exploration and Production faced: how to sever the connection between an offshore drilling rig with the seabed in case of an emergency.

Science Advances New mathematics accurately captures liquids and surfaces moving in synergy
A new mathematical framework developed at Berkeley Lab, published in the June 10, 2016 issue of Science Advances, allows researchers to capture fluid dynamics coupled to interface motion at unprecedented detail. The framework, called 'interfacial gauge methods', developed by Robert Saye, a Luis W. Alvarez Fellow in the Mathematics Group at Berkeley Lab, rewrites the equations governing incompressible fluid flow in a way that is more amenable to accurate computer modeling.

Public Release: 31-May-2016 Better combustion for power generation
As US utility companies replace coal-fired power plants with natural gas, a collaboration between GE and Oak Ridge National Laboratory is contributing to efficiency gains in GE's H-class gas turbines. GE researchers produced the first simulation involving multiple gas turbine combustors to study combustion interactions that are impractical to test physically. Advanced simulation is projected to results in a full percentage-point gain in turbine efficiency.

Current Biology Cuing environmental responses in fungi
Sensory perception lies at the heart of adaptation to changing conditions, and helps fungi to improve growth and recycle organic waste, and to know when and how to infect a plant or animal host. New results from a team led by DOE Joint Genome Institute researchers based on characterizing and then conducting a comparative analysis of two genome sequences published in Current Biology shed new light on the evolution of sensory perception in fungi.

Public Release: 25-May-2016 Radiation 101: DoseNet delivers environmental data as an educational tool
A network of radiation-monitoring devices and a companion website and open-source code serve as educational and outreach tools for an international project called DoseNet that stretches from Northern California classrooms to a city hall in Japan. Its broad aim is to inform and connect students and communities using science and data as common ground.

Trends in Microbiology A rallying call for microbiome science national data management
In a paper published online May 16, 2016, in Trends in Microbiology, researchers from the US Department of Energy Joint Genome Institute call for the formation of a National Microbiome Data Center to efficiently manage the datasets accumulated globally. By integrating and harnessing all available microbiome data and metadata, researchers could conduct larger-scale comparative analyses in order to address global challenges related to energy, environment, health and agriculture.

Journal of Physical Chemistry Letters Thinning out the carbon capture viscosity problem
Researchers have used computer modeling to design carbon dioxide binding materials so that they retain a low viscosity after sponging up carbon dioxide, based on a surprise they found in their explorations. Although the chemists still have to test the predicted liquid in the lab, being able to predict viscosity will help researchers find and design cheaper, more efficient carbon capture materials, they report in Journal of Physical Chemistry Letters.

Physics Review Letters Scientists take a major leap toward a 'perfect' quantum metamaterial
Scientists have devised a way to build a 'quantum metamaterial' -- an engineered material with exotic properties not found in nature -- using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.

Angewandte Chemie International Edition Plastic proteins: Synthetic material mimics essential characteristics of natural proteins
PNNL researchers hoping to design new materials for energy uses have developed a system to make synthetic polymers -- some would say plastics -- with the versatility of nature's own polymers, the ubiquitous proteins. Based on an inexpensive industrial chemical, these synthetic polymers might one day be used to create materials with functions as limitless as proteins, which are involved in every facet of life.

Agewandte Chemie Proving the genetic code's flexibility
Three-letter codons in a genome sequence can represent one of the 20 regularly used amino acids or stops. In the journal Angewandte Chemie International Ed., researchers from the US Department of Energy Joint Genome Institute and Yale University have discovered that microorganisms recognize more than one codon for selenocysteine. The finding adds credence to recent studies indicating that an organism's genetic vocabulary is not as constrained as had been long held.
