Auburn University is collaborating with the U.S. Army and the Federal Aviation Administration to develop innovative aviation learning and training modules using virtual, interactive and multimedia technology. The partnership seeks to develop gaming modules that can be implemented into the FAA's current curriculum for air traffic controllers.

A cooperative research and development agreement signed on Tuesday, June 6, enables Auburn's Warrior Research Center to join forces with the U.S. Army Game Studio, which is part of the U.S. Army Aviation and Missile Research, Development and Engineering Center, or AMRDEC, at Redstone Arsenal in Huntsville. The project is through the FAA's Air Transportation Center of Excellence for Technical Training and Human Performance, of which Auburn serves as a core team member.

The team will develop air traffic controller training technology using research and science-based knowledge on training adult learners and the use of gaming to improve learning and retention. The modules will demonstrate team capabilities to provide realistic, engaging and effective training.

AMRDEC's Army Game Studio has established unmatched capabilities in the development of virtual, interactive and multimedia technology used for outreach, recruiting, education and training. The studio brings together artists, soldiers and gaming experts to create virtual environments for soldiers to train in without putting them at risk in combat. Rapid prototyping of gaming technology tools ensures that the computer-generated training environments are user-friendly and customizable to the soldiers. The studio is best known for developing the free online U.S. Army video game, "America's Army."

"The Army Game Studio is my go-to place for any training, animation, augmented learning or virtual environment that I need," said JoEllen Sefton, director of the Warrior Research Center and associate professor in Auburn's School of Kinesiology. "I know that the talented team there can take anything we develop, or anything I can imagine, and make it real."

A cross-disciplinary effort, the Warrior Research Center is led by Auburn's School of Kinesiology in the College of Education and includes research from engineering, industrial design, psychology, business, veterinary medicine and human sciences. Collaborators also include Auburn's ROTC program, MRI Research Center, Center for Disability Research and Policy Studies and the Gastrointestinal Research Center, as well as the Edward Via College of Osteopathic Medicine on Auburn's campus.

Warrior Research Center investigations include the effects of military vehicles on a body's skeletal system, blood flow and muscles; consequences from prolonged helicopter sitting; evaluation of neck injuries from prolonged wear of helmets; reducing injury and improving warfighter performance. Studies also explore the design of a universal cockpit, controllers and pilot seats to improve mission efficacy and decrease pilot fatigue and injury.


GE chooses Auburn for advanced education program in 3-D printing

AU Professor Tony Overfelt

Overfelt is director of the Center for Industrialized Additive Manufacturing and principal investigator on a $1.5 million grant from the National Institute of Standards and Technology to research ways for smaller manufacturers to incorporate additive technology into their processes.


GE has chosen Auburn University as one of only eight universities from around the world to participate in the GE Additive Education Program. Auburn will receive a state-of-the-art Concept Laser MLAB 100R metal printer as part of this program, which will support Auburn’s ongoing research and education initiatives in additive manufacturing, also known as 3-D printing.

A GE advisory group composed of engineers and additive manufacturing specialists chose Auburn out of more than 250 applicants because of its established additive manufacturing curriculum and extensive research initiatives within the Samuel Ginn College of Engineering.

"Auburn Engineering is a national leader in industrialized additive manufacturing," said Christopher B. Roberts, dean of engineering. "Companies such as GE have asked for our help in graduating engineers who are well versed in additive manufacturing and prepared to lead American industry into the future.

"We responded by developing new curricula so students learn how to design for additive manufacturing systems. We are also investing millions of dollars in the latest 3-D printing technology and hiring world-class faculty to teach our students. This award further strengthens our relationship with GE, and we look forward to even greater collaboration with them in our education and research programs."

Additive manufacturing involves fabricating parts layer-by-layer from metals, plastics or other materials based on a 3-D computer-aided design model. Because parts are made by building upon each layer, additive technology reduces waste in the manufacturing process, improves production speed and can create parts that are lighter and more durable than those made using traditional manufacturing methods.

With the ability to create highly complex parts in a fraction of the time, additive technology is revolutionizing the manufacturing industry and creating new opportunities for engineers to explore. As an industry leader in this area, GE is using additive manufacturing to mass produce fuel nozzle injectors for jet engines at its plant in the city of Auburn’s Technology Park West.

Auburn Engineering faculty are also researching other ways to employ additive technology, such as producing next-generation rocket engines for space flights to Mars or developing intricate medical implants for use during surgery.

Auburn has created a new Center for Industrialized Additive Manufacturing, directed by materials engineering professor Tony Overfelt, and hired internationally known faculty working in this growing field of research. The university’s newly renovated Gavin Engineering Research Laboratory opens later this year and will feature dedicated space for Auburn’s additive manufacturing research, including upgraded and expanded testing equipment.

GE’s Additive Education Program was created to support colleges and universities such as Auburn that are educating students in additive manufacturing technologies. Through the program, GE is investing $8 million over five years to provide up to 50 metal additive machines to higher education institutions around the world. The printers are valued at $250,000 each.

"Additive manufacturing and 3-D printing is revolutionizing the way we think about designing and manufacturing products," said Mohammad Ehteshami, vice president of GE Additive. "We want a pipeline of engineering talent that have additive in their DNA. This education program is our way of supporting that goal."

Auburn professor develops cost-effective, staph-resistant bandage

Auburn University Professor Emeritus Dave Worley and postdoctoral fellow Buket Demir demonstrate how bacteria-resistant gauze is prepared.Staph infections affect thousands of people each year, often occurring as a person recovers from surgery or a wound. But an Auburn University professor has developed a better bandage that could keep you from becoming infected.

Professor Emeritus Dave Worley of the Department of Chemistry and Biochemistry in the College of Sciences and Mathematics is applying his patented N-halamine chemistry to gauze bandages to kill any bacteria that might contact a wound.

"A 2-inch-square bandage would cost only 3-4 cents more than a regular bandage," Worley said. "We tested it on Staphylococcus aureus and Pseudomonas aeruginosa. It kills them before they can infect the wound. Once a person becomes infected, the bacteria are hard to kill, especially if they are resistant to antibiotics."

Worley's process works by soaking the gauze in a solution of alcohol and an N-halamine compound containing chlorine. When the alcohol evaporates, the remaining solid, bacteria-killing compound adheres electrostatically to the bandage.

"You can shake the bandage, but the compound won't come out," said Worley, who says current bandages with silver also kill bacteria, but they are costly at up to $500 each. "We are at least as effective as silver at only a fraction of the cost."

Worley's research shows that N-halamine bandages should be kept away from light prior to use. "Our stability is good if you keep the bandages in opaque packages," he said. "Most wound dressings are replaced every one to two days, so ours are effective throughout the time they are worn."

The technology also works for air filters, surgical masks or any other disposable fibrous structure.

Worley's proof-of-concept research was funded by Auburn University's LAUNCH program that helps faculty move research ideas closer to the marketplace. He conducted the research with Professor T.S. Huang of the Department of Poultry Science, College of Agriculture; Professor Emeritus Roy Broughton of the Department of Mechanical Engineering, Samuel Ginn College of Engineering; and postdoctoral fellow Buket Demir of the Department of Chemistry and Biochemistry, College of Sciences and Mathematics.

Auburn's Office of Innovation Advancement and Commercialization has filed a U.S. patent application for the bandages, and is in the process of filing in multiple foreign territories, including Europe and several countries in Asia. The office is also pursuing licensing, including the possibility of forming a start-up company. Worley currently has 40 patents for developing the N-halamine chemistry, which was used to help form the HaloSource company in 1998 for bacteria-killing, rechargeable water filters.

"We are excited about licensing his bandage technology," said Brian Wright, associate director for commercialization. "This technology has application in health care as well as consumer products. The market potential is tremendous, but so is the possible positive impact on public health."

New peanut variety is first of its kind for Auburn

Dr. Charles Chen, professor of peanut breeding and genetics, displays the new peanut variety AU-NPL 17.

Charles Chen, professor of peanut breeding and genetics, says the new peanut variety AU-NPL 17 establishes a research pipeline for future releases.

Auburn University might be relatively new to the peanut breeding business, but its just-released runner peanut variety is already winning accolades for its high yields, resistance to disease and healthy traits.

The new release—AU-NPL 17—is the product of a peanut breeding program operated jointly by the College of Agriculture’s Department of Crop, Soil and Environmental Sciences and USDA’s National Peanut Research Lab in Dawson, Georgia. It’s the first runner-type cultivar released by the program and is well-adapted for growing conditions throughout the Southeast.

Runner peanuts are most commonly used for making peanut butter and are typically grown in Alabama, Georgia, Texas, Florida, South Carolina, Mississippi and Arkansas. They account for 80 percent of the estimated 1.5 million acres of peanuts grown in the United States, with Alabama growers planting approximately 175,000 acres this past year.

While the Auburn peanut breeding program is the youngest of its kind in the Southeast, it is rapidly making a name for itself, says Charles Chen, a former USDA Agricultural Research Service research geneticist who joined the College of Agriculture in 2012 and is a professor of peanut breeding and genetics.

“With the release of this first runner-type variety, we’re establishing a research pipeline,” Chen says. “Now we’ll be able to make new crosses or selections and other varieties can be released through the program. There’s always something to improve upon; you never reach perfection. That is why we are here.”

Future releases will build on AU-NPL 17’s high yield, disease resistance and other factors, he says.

“You can never totally suppress pests if you continue to grow a cultivar in the field,” Chen says. “By nature, pests will mutate and fight resistance and tolerance, so resistance eventually will be conquered by pest mutations.”

AU-NPL 17 has been tested throughout Alabama, Georgia, Mississippi and North Carolina, where runner-type peanuts of a medium maturity group are adapted.

“It has shown good adaptability, with its primary advantage being high yields and good adaptation from irrigated fields to nonirrigated, from single to twin-row patterns, and when grown with or without fungicide treatments,” Chen says.

In terms of yield per acre, AU-NPL 17 compares favorably with Georgia-06G, the University of Georgia release that has been the gold standard of Southeastern growers for several years now. In yield tests conducted in 2014 and 2015 in Headland, Fairhope, Dawson and Hattiesburg, Mississippi. AU-NPL 17 averaged 6,499 pounds per acre in eight tests as compared to Georgia-06G’s average of 6,175 pounds per acre.

In USDA Uniform Peanut Performance Tests 2016, AU-NPL 17 yielded higher than Georgia-06G in Alabama and North Carolina. In terms of ranking, the Auburn variety was ranked No. 1 in Alabama tests and No. 2 in North Carolina tests, with GA-06G ranking No. 5 in both tests.

AU-NPL 17 also is resistant to tomato spotted wilt virus and tolerant to leaf spot disease, both primary pest concerns for Southeastern growers. In addition, it has some resistance to white mold.

“In tests without fungicide treatments, AU-NPL 17 is generally more resistant or tolerant to tomato spotted wilt virus, early and late leaf spot and white mold than other cultivars in the test,” Chen says.

A healthier peanut

Auburn’s new peanut release also contains a higher amount of oleic acid compared to standard peanuts. Oleic acid is a monounsaturated fatty acid, also known as a “good fat,” that reduces the amount of LDL, known as “bad” cholesterol, while boosting the levels of “good” HDL. Monounsaturated fats are commonly found in foods such as nuts, seeds, olive oil, canola oil and avocados. This trait also substantially improves the shelf life of peanuts and peanut products.

“The industry is demanding a high-oleic peanut,” says Chen. In fact, Mars Chocolate, one of the top five peanut buyers globally, has committed to using 100 percent high-oleic peanuts in their products by the end of this year.

“We don’t produce as many high-oleic peanuts in the U.S. as countries such as Argentina and Australia, and that hurts our competitiveness internationally,” Chen says. “I believe high oleic will become the standard for U.S. peanut production.”

Yet another value of high-oleic peanuts is that peanut buyers normally pay farmers a premium for growing them.

Six-thousand pounds of breeder seeds of AU-NPL 17 will be planted this year by the Alabama Crop Improvement Association, Chen says.

“Hopefully, next year, we will have 120 tons of foundation seed,” he says. “We should have a few farmers growing the cultivar on a test basis in the spring of 2018, and most farmers will have the seed available to them in 2019.”

While the peanut cultivar breeding process typically takes about 10 years to complete, Chen was able to shorten it by a couple of years by growing peanuts in Puerto Rico during the winter months.

“Peanut breeders can send seed to Puerto Rico in November and then get increased seed back at the end of March to speed up the process,” he says. “We did that for two seasons, so it gave us a shorter interval with this cultivar.”

The first of many

John Beasley, professor and head of Auburn’s Department of Crop, Soil and Environmental Sciences, says AU-NPL 17 should prove to be of tremendous benefit to growers in Alabama and throughout the Southeast. Beasley should know; he was a peanut agronomist at the University of Georgia for 30 years before coming to Auburn.

“We’re very excited for Dr. Chen and his program,” Beasley says. “In addition to outstanding yields, this new cultivar also has resistance to some of the more common peanut diseases and, even more important, it has high oleic acid, which is now being required by the industry and demanded by consumers. AU-NPL 17 should be an especially good fit for Alabama producers, since it was developed and tested in the state, and it should help growers lower their seed and overall production costs.”

Beasley says AU-NPL 17 is the first of what will be many runner-type releases from the program at Auburn.

“We’re looking at sources from other programs, and our program will help to expand the genetic resources available in the Southeast,” he says. “This release certainly puts us on the map as far as breeding programs go, and we’re expecting many new releases in the coming years with different genetic traits.”

One area the breeding program will focus on in the future will be traits that enable more efficient plant water use, Beasley says. This would prove beneficial for producers in Alabama, where a majority of the cropland is not irrigated.


USDA NIFA funded research leads to new knowledge in catfish breeding in low oxygen environments

Zhanjiang (John) Liu, PhDProject director, Dr. Zhangjiang (John) Liu, Associate Provost/Associate VP-Research & Professor in the School of Fisheries, Aquaculture and Aquatic USDA NIFA LOGOSciences along with his research team comprised of Auburn Faculty members Rex Dunham and Eric Peatman and UAB Faculty member Degui Zhi, completed a study in August 2016 on Enhancing low-oxygen tolerance of catfish using genomics and genetics.  The two year research project funded by the USDA NIFA Special Research Grants in Aquaculture Research Program produced exciting results as the project summary below reveals.

Catfish is the leading aquaculture species for US aquaculture. In recent years, however, it has encountered unprecedented challenges due to fierce international competition and various production problems. Among these, the catfish industry lose tens of millions of fish due to mortalities caused by hypoxia alone, and more importantly, hypoxic exposures cause slow growth and induce disease outbreaks that in turn cause losses of hundreds of million dollars annually.  Among many things, it is widely believed that genetics research will provide the permanent solutions to the problems. In particular, application of modern genomics technologies will allow rapid and precise selection of superior brood stocks.  Our long-term goal is to enhance catfish stocks with superior performance traits to support a sustainable and profitable aquaculture industry. To reach this long-term goal, in this project, we will identify closely linked markers to the major gene locus controlling low-oxygen tolerance, and validate and apply such markers for selection of channel catfish and blue catfish used for the production of hybrid catfish, providing immediate benefits to the catfish industry. A major discovery of this project was the complexity of the genetic architecture of tolerance to low dissolved oxygen. In the early stages of this work, use of only one family led us to believe that a single locus could have been responsible for tolerance to hypoxia. However, additional studies reveal the complex nature of genetics for low oxygen tolerance. This discovery changed the community thinking on how to address the low oxygen tolerance through breeding.
