Alumni Survey ... The Department of Soil Science is undergoing a ten-year review of our programs and activities this fall and we need feedback from our alumni regarding the education you received here and your experiences with the Department. If you graduated with a degree in soil science (or were advised by a soil science faculty) within the last ten years or so, please take a few minutes to participate in the Soil Science Graduates Survey. All responses will be treated with full confidentiality and results will be reported only in aggregate.
Phil Barak’s latest research with the mineral struvite is highlighted in UW’s News: Soil scientist's fascination with mineral yields plan for battling it. The article can be found at http://www.news.wisc.edu/15422
The Wisconsin State Journal highlighted Joel Pedersen’s research on survival of prion proteins during wastewater treatment. The article, titled ‘Prions Can Survive Sewage Treatment’, was published in July 22, and can be found at http://www.madison.com/archives/read.php?ref=/wsj/2008/07/22/0807220025.php. The citation of the full research article is listed below.
Birl Lowery and Pete Nowak organized a special symposium at the Soil and Water Conservation Society Annual Conference on conservation issues related to the Midwest floods. The symposia was held on Tuesday, July 29th in Tucson, Arizona. A copy of the Abstract book can be downloaded from http://www.swcs.org/en/conferences/2008_annual_conference/
Bill Hickey has submitted a proposal to NSF entitled “Discovery of nanotubes in Burkholderia sp. Cs1-4” (July 08). This research explores the formation of extracellular tubular structures by Burkholderia, a polycyclic aromatic hydrocarbon-degrading bacterium isolated from PAH-contaminated soil in Wisconsin. These nanotubes are oblong structures surrounded by a proteinaceous coat, several micrometers in length and 10-50 nm wide, and are present both in cells grown in culture and in biofilms using a PAH as C source. A gene encoding one nanotube protein has been identified (NtbA) and sequenced. This gene was also found in an array of related and unrelated bacteria, which also grow nanotubes both in culture and biofilm conditions. The proposal seeks to discover the roles that these new structures may play in how these organisms interact with their soil environment.
