$1.44M grant to fund study on link between epigenetics, cancer By Jessica Luton jluton@uga.edu

Gone fishin’

Fisheries professor to study endangered Atlantic sturgeon in three Georgia rivers By Sandi Martin

UGA researcher Doug Peterson will use a nearly $500,000 grant from the National Marine Fisheries Service in partnership with the Georgia Department of Natural Resources to determine how well Atlantic sturgeon are reproducing in Georgia rivers two years after the species was listed as endangered. Biologists feared the fish’s populations had been lost from several of the state’s coastal waterways. Populations of the ancient fish appear to be rebounding in some parts of the country, spurring discussion about whether the Atlantic sturgeon should be downlisted from endangered status, said Peterson, a

fisheries professor in UGA’s Warnell School of Forestry and Natural Resources. However, there is no real evidence that the sturgeon is rebounding everywhere, particularly in the South Atlantic Distinct Population Segment, which includes Georgia. Peterson is launching a threeyear project to study the issue. “Although we’ve seen a significant increase in juvenile abundance in the Altamaha River, we remain very concerned about populations in the St. Marys, Satilla and Ogeechee rivers,” Peterson said. Peterson has shown in an unrelated project that the Atlantic sturgeon appears to be rebounding in Georgia. For the first time in decades, he documented sturgeon

reproduction in the St. Marys River. “We thought they were extinct there,” Peterson said, but earlier this year, while working on a new project for the U.S. Navy, his research team captured more than 10 young juveniles he believes were born in the St. Marys River. “Because Atlantic sturgeon return to spawn only in the same river where they were born, this was a significant and exciting find,” Peterson said. Atlantic sturgeon, targeted for their valuable caviar, were first protected from commercial fishing in 1996 after studies showed their numbers had declined dramatically, pushing them to the brink of extinction.The National Marine Fisheries See STURGEON on page 8

Top Thai teachers visit UGA for training By Kristen Morales kmorales@uga.edu

UGA hosted 16 science and education teachers fromThailand last month as part of the country’s efforts to learn the latest teaching methods. The program, a collaboration between the Thai government and UGA’S College of Education, combined site visits at local schools with workshops and seminars designed to give the teachers a global educational experience. The group participated in the Georgia STEM Forum held Oct. 20 and 21 and organized by the state Department of Education. “Thailand education has been

greatly influenced by other international systems, so we are now trying to enhance our mathematics and science teachers to study more about science, technology, engineering and mathematics education, and trying to adjust the concepts to fit with our country’s context,” said Savittree Rochanasmita Arnold, program coordinator in the UGA mathematics and science education department, who works with the Thai government on teacher training. During the first week of their visit, the teachers attended some welcome events and seminars at the College of Education, and they spent a morning at East Jackson

Comprehensive High School in Commerce, where they observed classes such as biology, art, world history and physical education. Their monthlong stay also included a visit to Whit Davis Elementary School in Athens, workshops at Sandy Creek Nature Center and the State Botanical Garden and classes in science teaching methods at the College of Education. Deborah Tippins, a professor in the mathematics and science education department who helped coordinate the visit, said this is one more way the department continues to help the Thai government prepare See TEACHERS on page 8

A UGA statistics researcher has been awarded a $1.44 million grant from the National Institutes of Health to develop statistical models that one day may be used to predict cancer and other diseases. Wenxuan Zhong, an associate professor in the Franklin College of Arts and Sciences’ statistics department, will use the funds to develop predictive statistical models based on epigenetic change patterns. Epigenetics is the study of changes in a gene’s behavior that can be passed down without actually altering the genetic code. Like an airport traffic controller, the epigenome passes along instructions that change the way the gene is expressed by switching genes “on” and “off.” For instance, twins have the

same genetic makeup, but they do not always experience the same illnesses, such as asthma or a mental illness. This is due to epigenetics, Wenxuan Zhong often a result of environmental factors. Zhong hopes to shed light on the role of epigenetic changes in illnesses, particularly cancer. One form of epigenetic change known as DNA methylation is particularly understudied in this area. “There’s a large amount of evidence that a process known as DNA methylation is a key player in cancer development,” Zhong said. “Today’s next-generation sequencing techniques give us the data we

commencement

Fall graduates will hear from alumnus and faculty member By Stephanie Schupska schupska@uga.edu

Roger Hunter, a UGA alumnus and associate director for programs at the NASA Ames Research Center, will deliver the university’s undergraduate Commencement address Dec. 19 in Stegeman Coliseum. The ceremony will begin at 9:30 a.m. with the graduate ceremony to follow at 2:30 p.m. The university’s graduate Commencement will feature Gregory H. Robinson, the UGA Foundation Distinguished Professor of Chemistry. Tickets are not required for the graduate exercise. For the undergraduate ceremony, commencement candidates are allowed six

UGA arts council Nearly 2 dozen student events added to annual Spotlight on the Arts festival By Camie Williams camiew@uga.edu

Students will be in the spotlight once again Nov. 6-14 during the third annual Spotlight on the Arts festival. In addition to the more than 60 events sponsored by the UGA Arts Council during the 2014 festival, nearly two dozen events have been organized and produced by students, including DJs in Snelling Dining Hall, a flash mob, an Alfred Hitchcock film festival, a comedy

show and several dramatic productions and musical performances. In an inaugural event called “4 minutes, 33 seconds: Spotlight on Scholarship,” graduate students in the arts will have a chance to share their research with the community. Inspired by John Cage’s 1952 composition 4’33”—which challenged audiences to reconsider the function of art and the borders between traditional art disciplines and between artistic practice and philosophy—students will
