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.

Qian Awarded $1.8M for Diabetes Research

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) awarded PNNL bioanalytical chemist Wei-Jun Qian a $1.8M grant for Type I diabetes research. Qian will use the funds over three years to develop proteomic signatures that can predict the progression of the disease in patients.

"Dream Team" Chosen to Study Basic Science of Nuclear Waste
Department of Energy selects PNNL-led team

To accelerate the scientific breakthroughs needed to support the Department of Energy's mission to clean up readioactive waste from World War II and the Cold War, four new Energy Frontier Research Centers have been formed. Energy Secretary Moniz announced that up to $40 million dollars will go to fund the four centers for up to four years. DOE's Pacific Northwest National Laboratory will lead one center called IDREAM, which stands for Interfacial Dynamics in Radioactive Environments and Materials.

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.
