Using innovative modeling and diagnostic methods, a research team led by Pacific Northwest National Laboratory demonstrated that higher-resolution models more accurately depict the interactions between particles suspended in air, called aerosols, and the complex processes within clouds. They identified the physical mechanisms behind the improved calculations, which could ultimately guide the development of next-generation climate models.

Bacteria’s Conflicts Fuel Synthetic Ecology Research
PNNL scientist describes process in Science Perspective
In mixed populations of microbes, some bacteria, the "cooperators," dominate over others, the "cheaters." Cheaters use resources cooperators make and share, and the community suffers from depleted common resources. In Science, PNNL Laboratory Fellow Jim Fredrickson took on the tragedy of the commons in microbial communities. Understanding how microbes interact could help scientists design synthetic communities for use in biotechnology, turning tragedy into progress.

Please Do Spill the Oxygen
like how tea flows through a leaky mug to pool under a table cloth, so oxygen
atoms spill out of a tiny cluster to pool under a graphene surface. For the
first time, scientists at Pacific Northwest National Laboratory and
Karl-Franzens University showed how the oxygen spills from the clusters to pool
under a sheet of graphene, a designer material that could change the next
generation of catalysts, fuel cells, and sensors.
Scientists show how clusters funnel atoms to create oxygen pools that benefit biofuels, fuel cells, and sensors
The August 2015 issue of Computer, focused on “Irregular Applications,” owes its editorial direction to two guest editors: Antonino Tumeo, of ACMD Division’s HPC group, and John Feo, who recently rejoined PNNL as the new co-director of the Northwest Institute for Advanced Computing. In the issue, Tumeo and Feo take a holistic look at irregular behaviors in computing systems at all layers of the software and hardware stack. They also provided the magazine’s introduction and selected the featured articles, including one co-authored by Mahantesh Halappanavar, from ACMD Division’s Data Sciences group.
