Nature Team advances understanding of the Greenland Ice Sheet's meltwater channels
A paper in Nature this week notes that observations of moulins (vertical conduits connecting water on top of the glacier down to the bed of the ice sheet) and boreholes in Greenland show that subglacial channels ameliorate the speedup caused by water delivery to the base of the ice sheet in the short term. By mid summer, however, the channels stabilize and are unable to grow any larger.

Proceedings of the National Academy of Sciences Breakthrough antibacterial approach could resolve serious skin infections
In several cases, scientists found an ionic liquid was more efficacious on a pathogenic biofilm than a standard bleach treatment and exhibited minimal cytotoxicity effects on human cell lines (unlike bleach). This has excellent prospects for aiding antibiotic delivery to the pathogen through biofilm disruption.

Nature Geoscience Scientists uncover combustion mechanism to better predict warming by wildfires
Scientists have uncovered key attributes of so-called 'brown carbon' from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material's warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the University of Montana in the journal Nature Geosciences this week.

Public Release: 18-Jun-2014 Probing Fukushima with cosmic rays should speed cleanup
A Los Alamos technique called muon tomography can safely peer inside the cores of the Fukushima Daiichi reactors and create high-resolution images of the damaged nuclear material inside without ever breaching the cores themselves. The initiative could reduce the time required to clean up the disabled complex by at least a decade and greatly reduce radiation exposure to personnel working at the plant.

Proceedings of the National Academy of Sciences Power plant emissions verified remotely at Four Corners sites
Air pollution and greenhouse gas emissions from two coal-fired power plants in the Four Corners area of northwest New Mexico, the largest point source of pollution in America, were measured remotely by a Los Alamos National Laboratory team. Led by Laboratory senior scientist Manvendra Dubey, the study is the first to show that space-based techniques can successfully verify international regulations on fossil energy emissions.

Nature Photonics Shiny quantum dots brighten future of solar cells
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca, Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.

Society of Toxicology Annual Meeting ATHENA desktop human 'body' could reduce need for animal drug tests
Creating surrogate human organs, coupled with insights from highly sensitive mass spectrometry technologies, a new project is on the brink of revolutionizing the way we screen new drugs and toxic agents.
ATHENA, the Advanced Tissue-engineered Human Ectypal Network Analyzer project team, is developing four human organ constructs -- liver, heart, lung and kidney -- that are based on a significantly miniaturized platform.

Proceedings of the National Academy of Sciences 'Fore!' heads up, wide use of more flexible metallic glass coming your way
Tweaking the shearing characteristics of materials such as glass has important applications well beyond the sporting worldof glass-faced golf clubs, it's a matter of broader impact, aiding such fields as space science, electrical transformers, cell phone cases, and yes, golf clubs, because their mechanical and magnetic properties are highly adjustable.
