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.

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.

Proceedings of the National Academy of Sciences Cloudy problems: Today's clouds might not be the same as pre-industrial ones
Clouds are notoriously hard to simulate in computer programs that model climate. A new study in the Proceedings on the National Academy of Sciences Early Edition suggests why -- either clouds are more variable than scientists give them credit for, or those bright white clouds in the sky are much dirtier than scientists thought.
