The Chattanooga Times Free Press interviewed Aimee Classen, associate professor of ecology and evolutionary biology, who has received more than $880,000 from the U.S. Department of Energy to investigate often-overlooked carbon cycle players. Classen and her team will examine factors that influence carbon cycling below the ground and are not included in today’s carbon-cycle models. They
Frank Loeffler, UT-ORNL Governor’s Chair for Microbiology, was featured in Science-Omega for his research involving nitrous oxide. Loeffler and his international team has discovered that the range of microorganisms which combat the greenhouse gas is broader than expected.
The environment has a more formidable opponent than carbon dioxide. Another greenhouse gas, nitrous oxide, is 300 times more potent and also destroys the ozone layer each time it is released into the atmosphere. Luckily, nature has a larger army than previously thought combating this greenhouse gas—according to a study by Frank Loeffler, Governor’s Chair for Microbiology, and his colleagues.
Duke University professor Rob Jackson will be at the University of Tennessee, Knoxville, on Thursday to kick off this semester’s energy-environmental forum with a discussion of the link between the “hydrofracking” method of shale gas extraction and methane contamination of drinking water.
UT Knoxville is being honored again for its sustainability efforts. The Southern Alliance for Clean Energy gave UT the Green Power Leadership Award for the campus’s commitment to advancing renewable energy.
On April 20th, British Petroleum’s Deepwater Horizon offshore oil drilling platform exploded. WUOT 91.9 FM’s Chrissy Keuper spoke with UT Knoxville professor Gregory Button, who studies environmental disasters and recovery, including the Exxon Valdez oil spill and Hurricane Katrina.
UT Knoxville is among the nation’s most environmentally responsible institutions, according to The Princeton Review, one of the nation’s top education service and evaluation companies. UT Knoxville is one of only five universities in Tennessee to be included in the company’s newest guidebook, “Guide to 286 Green Colleges,” and is mentioned for its “Make Orange Green” program and other initiatives.
UT Knoxville students, faculty, staff and community are invited to participate in a conference call with the offices of Tennessee Senators Lamar Alexander and Bob Corker to hear directly from Senate staffers on climate and energy policy. Dubbed “Let’s Talk, Tennessee,” the conference call will take place on Monday, April 12 at 11 a.m.
Mercury pollution is a persistent problem in the environment. Human activity has led to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges for the heavy metal. It’s that persistent and toxic nature that has flummoxed scientists for years in the quest to find ways to mitigate the dangers posed by the buildup of mercury in its most toxic form, methylmercury. A new discovery by scientists at UT Knoxville and Oak Ridge National Laboratory, however, has shed new light on one of nature’s best mercury fighters: bacteria.
Faculty Senate President and professor of philosophy John Nolt speaks with the UT Minute staff about UT’s efforts to create and maintain a sustainable campus.
