Three Views are Better than Two
Researchers found that a three-dimensional representation of atmospheric particles increases understanding of their cloud-changing skills
PNNL developed a novel three-dimensional particle representation for aerosol modeling. This new add-on solves for particle size, the amount of the black carbon in the particle, and the particle's ability to attract moisture. The novel approach, called MOSAIC-mix, improves model predictions of how the particles handle sunlight energy and which will become cloud seeds.
The Case of the Cobalt Catalyst
The story's plotline could solve other mysteries around generating electricity without fossil fuels
It's the worst short story ever written: on a dark and stormy night; the end. The real story -- the context, the tension, and the motivations -- are missing. That's what it feels like for scientists reading the reaction that uses a cobalt catalyst to produce hydrogen. Dr. Eric Wiedner and Dr. Morris Bullock at the Center for Molecular Electrocatalysis at Pacific Northwest National Laboratory wanted to know the rest of the story. They found out what happened between the first page and the last.

A New Model for Simulating the Atmosphere of Ions Around DNA
Refined insights into critical ionic interactions with nature's building blocks
In nature, DNA exists within a solution rife with electrostatically charged atoms or molecules called ions. A recent study led by Pacific Northwest National Laboratory researchers investigated a new model of how B-DNA, the form of DNA that predominates in cells, is influenced by the water-and-ions “atmosphere” around it.
