The school is one of the largest atmospheric and environmental academic research centers in Britain. Pearce, who came to the Laboratory in 2009, is investigating how minerals and microbes affect technetium and other radionuclides in the soil at a former plutonium production site in southeastern Washington State. ]]>Thu, 19 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=696Results: A recently published Pacific Northwest National Laboratory study of a naturally bioreduced sediment sample from a former uranium mill tailings site reveals insights that enhance understanding of the long-term persistence of uranium in groundwater. The study provides the first-ever evidence of a useful pyrite mineral formation within the sample. ]]>Wed, 18 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=695Frontiers in Biological Sciences Seminar Series.

Pratt on her selection for a postdoctoral fellowship in climate and global change from the National Oceanic and Atmospheric Administration (NOAA). Pratt was one of ten researchers that NOAA chose in 2009 as part of its national program to create and train the next generation of climate research leaders. Pratt decided to spend her two-year fellowship, which began in October 2009, at Pacific Northwest National Laboratory. ]]>Sun, 15 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=692Dr. Michael Thackeray at the Pacific Northwest National Laboratory's Frontiers in Materials Sciences Seminar Series.

This is the first testbed of its kind designed to quantify the performance of aerosol process modules over spatial scales consistent with measurements collected during field campaigns. ]]>Mon, 09 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=693Scientific Computing ]]>Mon, 09 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=690Dr. Jerome Fast on his appointment as an affiliate scientist for the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.  The University Corporation for Atmospheric Research Board of Trustees appointed Fast to the three-year position starting November 1, 2009. As part of his appointment, Jerome will work in Boulder for at least three months, collaborating with scientists in the Atmospheric Chemistry Division of NCAR on aerosol modeling projects.  ]]>Thu, 05 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=687Results: Your high school science experiments were fun, smelly, and perhaps even offered a peek into the impossible possibilities of science, but they couldn't have prepared you for the direction science is taking. A new biology—one that integrates the expertise of chemists, physicists, computer scientists, engineers, and mathematicians—is being called for to help solve some of the thorniest energy, environmental, and climate challenges facing the United States today, according to a new report by the National Research Council. Dr. Tony Janetos, a member of the National Research Council committee that wrote the report, directs the Joint Global Change Research Institute, a partnership between Pacific Northwest National Laboratory and the University of Maryland. ]]>Wed, 04 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=688Results: Whole water molecules form complex shapes around hydroxide ions, simple negatively charged particles, according to a recent study by scientists at Pacific Northwest National Laboratory. The shapes are the result of hydrogen bonds between the ions and the molecules. This research answers the question, debated in scientific circles for more than 70 years, of how hydroxide ions get oriented in water. This work graced the cover of the October 19, 2009, issue of Chemical Physics Letters. ]]>Tue, 03 Nov 2009 00:00:00 GMT
