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.

Scientists showed that uranium attached to soil particles and moved slowly when the groundwater was at neutral pH and contained low levels of carbonate ion or dissolved carbon dioxide. Such conditions often occur at riverbanks when the river water rises and mixes with the groundwater. This work appeared in the September 1 issue of Environmental Science & Technology. ]]>Mon, 26 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=681Tue, 13 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=680Dr. Richard D. Smith, who received the 2009 Human Proteome Organisation (HUPO) Discovery Award for Proteomic Sciences. The award is for a single discovery in the field and consists of a plaque and $3000. Smith was honored at the HUPO 8^th Annual World Congress September 26-30 in Toronto, where he presented a major lecture on some of the proteomics developments that earned him this recognition. ]]>Wed, 07 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=678Results: Scientists as superheroes? Well, maybe, at least in their ability to "see" through subsurface soil and rock, by using a new technique for monitoring groundwater contamination that eliminates the need to drill wells. Scientists recently performed the first field demonstration of a minimally invasive monitoring approach for tracking subsurface biogeochemical changes accompanying the bioreduction of a uranium-contaminated aquifer. Their results showed that the approach, called surface spectral-induced polarization (SSIP), is both feasible and practical for remote monitoring of microbial activity stimulated during microbiological reduction. ]]>Thu, 01 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=677Wed, 30 Sep 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=676Mon, 28 Sep 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=671Pacific Northwest National Laboratory.
