Unlocking Cloud Gridlock
Even as computing power increases, current climate model formulas struggle to handle storm clouds at today's higher resolutions and smaller model grid sizes. Cumulus storm cloud systems are still only partially resolved. Armed with a new formula developed by a PNNL-led research team, the approach breaks the storm cloud modeling gridlock by more accurately depicting how cumulus clouds transport moisture through the atmosphere.

Low-Dose Radiation Impacts Skin Sensitivity
Scientists at Pacific Northwest National Laboratory exposed human skin tissue samples to low doses of
ionizing radiation and found that
the skin showed perturbations that suggest its stability is altered. This, in turn, could change skin's sensitivity after exposure to insults, such
as infection. Understanding
the effects of low-dose radiation exposure is important for
protecting the population and environment from potentially harmful effects
of increased exposures.

The Softer Side of Control without Clumping or Capping
Replacing some or all of the platinum in fuel
cells with common metals in a reactive, highly tunable nanoparticle form may
expand fuel cell use. At Pacific Northwest National Laboratory, scientists
created reactive, tunable, bare nanoparticles using a new technique combined
with ion soft landing.
Creating bare, two-metal particles provides insights into potential substitutes for costly platinum in fuel cell catalysts

StreamWorks: Pattern Detection for Your Protection
Novel graph method detects cyber-attack patterns in complex computing networks
Detecting cyber security breaches and identifying their attack patterns in complex computing networks as they emerge in real time remains a paramount concern and growing challenge. In their work involving streaming graphs, scientists at PNNL and Washington State University, devised a novel framework, StreamWorks, that categorizes cyber attacks as graph patterns, which then can be examined using a continuous search on a single, large streaming dynamic graph. Identifying events and patterns as they emerge will go a long way in evading and mitigating the computer network intrusions that have potentially criminal, even dangerous, consequences and have made cyber security a multi-billion dollar industry.
