Bailey is a soil scientist and microbial ecologist who has been actively involved with EMSL as part of its Science Theme Advisory Panel for Geochemistry/Biogeochemistry and Subsurface Science. ]]>Tue, 01 Oct 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1464Chemical & Engineering News reporter Carmen Drahl in the September 16 issue. "NMR Method Can Chase Down Chemical Threats," described the researchers' use of nuclear magnetic resonance spectroscopy to clearly distinguish different salt forms of the highly toxic alkaloid strychnine from one another based on the way different counterions such as chloride or sulfate influence the NMR spectra. ]]>Wed, 25 Sep 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=14522013 Key Scientific Accomplishments report is now available as a downloadable PDF. This 32-page full-color brochure highlights some of the year's most noteworthy achievements by Pacific Northwest National Laboratory scientists, all of which have impacted science and some of the most important global challenges in energy, security, and environmental sustainability. ]]>Wed, 11 Sep 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1441Results: To enhance the study of subsurface microbial communities underlying the U.S. Department of Energy's Hanford Site, scientists at Pacific Northwest National Laboratory developed a novel analytical framework that advances ecological understanding in two primary ways. ]]>Wed, 28 Aug 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1413Met), developed by a team of Pacific Northwest National Laboratory (PNNL) scientists, won an R&D 100 Award from R&D Magazine. The team's award brought the total number of PNNL R&D wins to 90 since the contest began in 1963. ]]>Fri, 12 Jul 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1412Results: Microbial genomes have incredible functional and regulatory complexity, making them of great interest for potential environmental, energy, health, and industrial applications. In a study published in PLoS Genetics, scientists at the University of California, San Diego (UCSD) and Pacific Northwest National Laboratory (PNNL) used an integrated bioinformatics and multi-omics approach to characterize the genome organization of Thermotoga maritima, a bacterium that grows at temperatures between 131-194°F. Their approach revealed organizational features within the genome that lead to and regulate protein expression. ]]>Thu, 11 Jul 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1406Salmonella, take over beneficial bacteria within the gut amid previously unseen changes to the gut environment. The results provide new insights into the course of infection and could lead to better prevention or new treatments. ]]>Mon, 01 Jul 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1403Results: When the water-dwelling microbe Sideroxydans lithotrophicus ES-1 connects with iron mineral particulates, three microbial proteins quickly extract electrons from divalent iron or Fe(II), leaving behind trivalent iron, according Pacific Northwest National Laboratory and Lawrence Berkeley National Laboratory scientists. The oxidation reaction begins when the protein contacts the particle's surface and continues into the particle interior, without damaging the iron lattice. The electron transfer is faster if the particle starts with a high ratio of Fe(II) to Fe(III). ]]>Wed, 26 Jun 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1396Results: Bacteria can move electrons at least half a millimeter across a scaffolding made by themselves, of themselves, even under starving conditions; that is, when cells at the bottom of the bacterium biofilm do not have access to their electron donor and carbon source. This new finding by a scientific team from Pacific Northwest National Laboratory, Washington State University, and Argonne National Laboratory challenges conventional wisdom, which held that electrical resistance within bacterial biofilms-robust structures held together by a strong matrix-would restrict long-range electron transfer. ]]>Wed, 29 May 2013 00:00:00 PSThttp://www.pnnl.gov/science/highlights/highlight.asp?id=1388Radiation Research. The review, by Laboratory Fellow Dr. William F. Morgan and retired PNNL scientist Dr. William J. Bair, highlights critical areas of controversy in low-dose radiation biology, and suggests areas of future research to address these issues. ]]>Mon, 13 May 2013 00:00:00 PST
