KNOXVILLE—After five years of sluggish recovery, the U.S. and Tennessee economies are poised for strong growth in 2014 and 2015.

Despite the slow pace of the recovery, many indicators—including an increase in consumer confidence, rallying stock market prices, and rising home prices—point to brighter growth prospects in the quarters ahead, according to the forecast in the 2014 Economic Report to the Governor of the State of Tennessee, released Friday.

The study, prepared by the Center for Business and Economic Research at the University of Tennessee in Knoxville, predicts the course of the state and national economies by examining many fiscal factors and trends.

Household net worth grew by almost 10 percent in 2013, surpassing its pre-recession level for the first time. [Read more…]

UT research finds link between alcohol use, not pot, and domestic violence

KNOXVILLE—Alcohol use is more likely than marijuana use to lead to violence between partners, according to studies done at the University of Tennessee in Knoxville.

Research among college students found that men under the influence of alcohol are more likely to perpetrate physical, psychological, or sexual aggression against their partners than men under the influence of marijuana. Women, on the other hand, were more likely to be physically and psychologically aggressive under the influence of alcohol, but, unlike men, they were also more likely to be psychologically aggressive under the influence of marijuana.

The research has implications for domestic violence intervention and prevention programs. [Read more…]

KNOXVILLE—Technology that lights up cells to enable study of the effects of drugs and monitor disease is among The Scientist magazine’s Top 10 innovations of 2013. It’s also a University of Tennessee technology and licensed by a Knoxville-based startup company.

Technology using humanized bacterial luciferase developed by UT researchers and licensed by 490 BioTech, founded by two UT Knoxville faculty members and two then-graduate assistants, is ranked sixth on the magazine’s list. For more about the innovation list, visit here.

“The development of this technology originated more than 10 years ago, and with hard work by past graduate students and key financial support from the National Institutes of Health, the National Science Foundation, and University of Tennessee Research Foundation, it evolved into a marketable product that can be used to make pharmaceutical drugs safer, better, and cheaper,” said Steven Ripp, co-founder and chief operating officer of 490 BioTech and research associate professor at UT Knoxville. “Being recognized as a Top 10 technology is a significant milestone for our company, and it will greatly assist in mainstreaming our product toward better disease management and improved health care.” [Read more…]

UT Students Measure Soil Carbon Flux

KNOXVILLE—Carbon dioxide is key to life on Earth, but too much of the good thing can overheat the Earth’s surface and hurt the very things it supports. Thus, understanding how carbon cycles through the atmosphere is crucial to predicting its effects.

A University of Tennessee professor in Knoxville has received more than $880,000 from the U.S. Department of Energy to investigate often-overlooked carbon cycle players.

Aimee Classen, associate professor of ecology and evolutionary biology, and her team, which includes Oak Ridge National Laboratory staff members, will examine factors that influence carbon cycling below the ground and are not included in today’s carbon-cycle models.

“We know that tiny things that live in soil, like fungi, can regulate carbon processes in forests. However, our current soil models don’t consider what role fungal and plant root activity may play in soil carbon dynamics. Our project aims to fill this knowledge gap,” Classen said. [Read more…]

KNOXVILLE—Imagine going to the doctor and the doctor peering into your genetic code to determine the best medicine to treat what ails you.

The University of Tennessee in Knoxville has received funding from computer chip maker Intel to develop computer codes to make personalized medicine like this and other transformative scientific discoveries possible.

The funding will open an Intel Parallel Computing Center at the Joint Institute for Computational Sciences, or JICS, at UT and Oak Ridge National Laboratory. Parallel computing, used in supercomputers, is a form of computation in which many calculations are carried out simultaneously. The focus of the center will be to take supercomputing to the next level to meet scientific computing demands. Today’s research faces limitations due to the amount of data, time, and energy it takes to run calculations. [Read more…]

KNOXVILLE—When John was diagnosed with HIV in 1990, he never would have imagined he would be alive to celebrate his 50th birthday.

Twenty-three years later, the Oak Ridge resident views his life with the sense of appreciation and perspective that can only come from someone forced to face his own mortality.

“My life is a lot different,” he said, “but I wouldn’t trade it for anything.”

John is one of five East Tennesseans featured on a new WUOT special, “I’m Still Here: My HIV Life.” The program will air during “Morning Edition” and “All Things Considered” on Wednesday, Nov. 6. [Read more…]

KNOXVILLE—Although a turtle’s home may be on its back, some North American turtles face an uncertain future as a warming climate threatens to reduce their suitable habitat.

A new study conducted at the National Institute for Mathematical and Biological Synthesis at the University of Tennessee in Knoxville reconstructs the effects of past climate changes on 59 species of North American turtles and finds that the centers of the turtles’ ranges shifted an average of 45 miles for each degree of warming or cooling. While some species were able to find widespread suitable climate, other species, many of which today are endangered, were left with only minimal habitat.

Species in temperate forests and grasslands, deserts and lake systems, primarily in the central and eastern United States, were more affected by climate change than species along the Pacific Coast, in the mountain highlands of the western United States and Mexico, and in the tropics, according to the study, published in the journal PLOS ONE.

KNOXVILLE—The question of what to do with spent nuclear fuel in the U.S. has never been definitively answered. A University of Tennessee in Knoxville professor has received funding from the U.S. Department of Energy to develop new capabilities for evaluating potential alternatives to directly disposing of used fuel.

The award is part of the DOE’s 2013 Nuclear Energy University Programs which is awarding $42 million to 38 American universities and colleges for nuclear energy research and development projects focused on developing innovative solutions.

A proposal by Steven Skutnik, assistant professor in nuclear engineering, was awarded $755,000 to develop new capabilities for a fuel cycle simulator called CYCLUS by building on an Oak Ridge National Laboratory software package for nuclear fuel modeling called ORIGEN. [Read more…]

KNOXVILLE—Some things are not always what they seem—even in space. For 30 years, scientists believed a large near-Earth object was an asteroid. Now, an international team including Joshua Emery, assistant professor of earth and planetary sciences at the University of Tennessee in Knoxville, has discovered it is actually a comet.

Called 3552 Don Quixote, the body is the third largest near-Earth object—mostly rocky bodies, or asteroids, that orbit the sun in the vicinity of Earth. About 5 percent of near-Earth objects are thought to be “dead” comets that have shed all the water and carbon dioxide in the form of ice that give them their coma—a cloud surrounding the comet nucleus—and tail.
