Sharon Long Receives CALS Award

long_md Congratulations to Sharon Long (Professor, UW-Madison Department of Soil Science) on receiving the 2016 CALS Equity and Diversity Award. The award will be presented at the CALS Awards Program on Wednesday, May 4. The program will begin at 3 pm in the Ebeling Symposium Center in the Microbial Sciences Bldg. and a reception will follow. Look for more details at a later date. We are very pleased that Sharon has received this well-deserved honor for her many contributions not only to the Department but to CALS and the whole university!

National Competition Selects Three Winners to Advance Water Entrepreneurship, Resiliency and Sustainability

barak_labNRU, Nutrient Recovery & Upcycling, LLC, nrutech.com, was one of three winners in the Empowering Opportunities in Water competition conducted by The Water Council (a nonprofit based in Milwaukee), the Wisconsin Economic Development Corporation, and Veolia (a global company specializing in resource management, including water). NRU is a spin-off company from the Barak Lab in the Department of Soil Science at the UW-Madison, with the goal of commercializing the intellectual property developed in that lab. The three principals of NRU are Professor Phillip Barak, Mauricio Avila (MS, Soil Sci., 1999; PhD, Soil Sci., 2004) and Menachem Tabanpour (President of NRU). This award recognizes a patented technology to recover phosphate in the form of brushite from wastewater treatment plants.  For more information on NRU, check out their promotional video.  (https://youtu.be/TpufdQmlDeg).

Lithium Battery Catalyst Found to Harm Key Soil Microorganism

Soil-bacterium-cropped-600x338

The material at the heart of the lithium ion batteries that power electric vehicles, laptop computers and smartphones has been shown to impair a key soil bacterium, according to new research published online in the ACS journal Chemistry of Materials. The study by researchers at the University of Wisconsin (UW) – Madison and the University of Minnesota is an early signal that the growing use of the new nanoscale materials used in the rechargeable batteries that power portable electronics and electric and hybrid vehicles warrant evaluation for their potential environmental consequences. The research team led by UW-Madison chemistry Professor Robert J. Hamers explored the effects of the emerging battery cathode material nickel manganese cobalt oxide (NMC) on the common soil and sediment bacterium Shewanella oneidensis. “As far as we know, this is the first study that’s looked at the environmental impact of these materials,” says Hamers, who collaborated with the laboratories of University of Minnesota chemist Christy Haynes and UW-Madison soil scientist Joel Pedersen to perform the new work.

New Models to Study Nanoparticle Interaction with Cell Membranes

CoverIssueAn article by Melby et al. will soon be featured in the journal Environmental Science Nano. The paper focuses on the development of models for cell surfaces for the purpose of studying how engineered nanoparticles interact with organisms. The authors show that by incorporating domains differing in fluidity in model cell membranes (lipid bilayers), the attachment of positively charged nanoparticles is increased over the case where such domains are absent. The lead author is Eric Melby (Ph.D. candidate in Environmental Chemistry and Technology in Joel Pedersen’s group; M.S., Soil Science, 2010 under Doug Soldat). A lay description of the study can be found on their blog site: http://sustainable-nano.com/2015/11/19/whats-in-a-name/.

Excellence in Science Nomination for Jenna Grauer-Gray

Jenna

Jenna Grauer-Gray, a MS Student of Alfred Hartemink, has been nominated by Dean VandenBosch for participation in the AAAS/Science Program for Excellence in Science. This program rewards deserving graduate students, medical students, and postdocs working in the life sciences with a three-year sponsored membership in AAAS/Science.

AAAS is the world’s largest multidisciplinary science organization, with nearly 130,000 members and subscribers. Its mission is to work toward sound science policy, improved science education, greater international cooperation, and increased public interest in scientific discovery.

Thea Whitman in Nature Communications!

Whitman2Our new soil ecologist just published a paper in Nature Communications, entitled “A dual-isotope approach to allow conclusive partitioning between three sources.” The paper describes a new technique to separate one biogeochemical pool (e.g., total soil CO2 emissions) into its three different sources (e.g., roots, soil organic carbon, and plant litter). The approach uses just two stable isotopes, expanding the range of possible questions and making it a powerful tool to help advance our understanding of element cycling in complex systems. Go to

325 Field Trip

_DSC6917 (2)As part of the Soil Science 325 course, a group Antigo silt loam state soilof soil science students went on a three-day field trip and visited the Antigo silt loam – the State Soil of Wisconsin! The Antigo silt loam was selected to represent the more than 550 different soils in Wisconsin thanks in no small part to the efforts of Francis Hole. The field trip was supported by the FD Hole Endowment.   {L to R, bottom to top:  Kavya Krishnan, Jacob Kruse, Luis Reyes Rojas, Nicholas Galleguillos Katz, Jenifer Yost, Kyle Kazmierczak, Galen Bergquist, David Ritter, Elizabeth McNamee, Professor Alfred Hartemink, Kristin Witkowski}. https://www.myuwconnect.org/give?id=3D4058BD-AD83-4728-B6F0-D55A1098324F

Announcing the Jackson-Tanner Commons Project

Soil-King Observatory DriveThe Jackson-Tanner Commons Project is an effort by the Department of Soil Science to provide a new academic workspace where students, staff, and faculty members can interact informally in a relaxed and pleasing environment. Named after our first two faculty members to be elected to the National Academy of Sciences, Marion Jackson and Champ Tanner, the Jackson-Tanner Commons will be housed in Room 360 of the Soils Building. For more information or to donate to the effort, please see the Jackson-Tanner Commons webpage under Alumni & Friends.
