McComas Elected Fellow of the American Association for the Advancement of Science
|University of Arkansas Professor William F. McComas has been named a Fellow of the American Association for the Advancement of Science. The honor is bestowed by peers in recognition of work deemed scientifically or socially significant. |
McComas is the inaugural holder of the Parks Family Endowed Professorship in Science Education in the Department of Curriculum and Instruction in the College of Education and Health Professions. McComas directs the Project to Advance Science Education.
“Being elected a Fellow in a major scientific society such as AAAS is a wonderful honor for an educator, and is particularly appropriate as it recognizes that scientific discovery and education are inexorably intertwined,” McComas said. “We in science education are charged with translating the work of those engaged in scientific research to inform classroom teachers at all levels, help prepare the next generation of scientists, and assist in communicating the results of science to enlighten the public and inform decision-makers.”
| ||Tune in now to Short Talks From the Hill, a new podcast from the University of Arkansas. |
This podcast features stories of discovery across the U of A campus — from renowned historian and Distinguished Professor Randall Woods discussing his new book on Lyndon Johnson and the Great Society to a graduate student who discovered the re-emergence of the northern saw-whet owl in Arkansas.
A new podcast will air every three weeks and can be heard on researchfrontiers.uark.edu or kuaf.com.
Scheduled programming includes: “How we feel about spending our bottom dollar,” Robin Soster, assistant professor of marketing; “Searching for the saw-whet owl,” Mitchell Pruitt, graduate student; “Understanding the Federal Reserve and stress testing community banks,” Tim Yeager, professor of finance; and “Food scarcity in Northwest Arkansas,” Kevin Fitzpatrick, professor of sociology.
Future broadcasts also include: “LBJ and the Great Society,” Randall Woods, Distinguished Professor of history; “The dreaded earworm,” Elizabeth Margulis, professor of music; “Graphene, a two-dimensional powerhouse,” Paul Thibado, professor of physics; and “Teeth, a very short introduction” – Peter Ungar, Distinguished Professor of anthropology.
|The National Science Foundation has awarded a one-year, $100,000 grant to bioanalytical chemist Julie Stenken to serve as a scholar in residence at the U.S. Food and Drug Administration in Silver Spring, Maryland. |
The project will focus on monitoring chemical communication called “quorum sensing” arising from thin films of bacteria that adhere to medical implants such as catheters, ventilators – even artificial joints. About 60 percent of healthcare-associated infections are caused by infection of medical devices, leading to about 100,000 deaths annually. The Food and Drug Administration regulates medical devices.
Stenken, a professor in the Department of Chemistry and Biochemistry, is a leading expert in the technique of microdialysis sampling. Stenken, will work with Dr. Steven Wood, an immunologist at the Food and Drug Administration who has experience with medical devices. A microdialysis is a probe that is placed under the skin to mimic medical implants.
“We will use microdialysis sampling to monitor the chemical communication between bacteria in a biofilm and extend this to complex systems involving biofilms and macrophages,” Stenken said.
A team of biomedical engineering researchers at the University of Arkansas have identified a cause of fluid swelling of the brain, or cellular edema, that occurs during a concussion.
The researchers discovered that pre-treating the cells with an existing, FDA-approved drug used for epilepsy and altitude sickness reduces the expression of a specific protein that causes swelling.
Their findings were published in a recent issue of Nature’s Scientific Reports.
“Our study found that mild traumatic brain injury resulted in increased expression of a protein called aquaporin-4, which caused a massive cellular influx of fluid, leading to increased astrocyte cell volume and injury,” said Kartik Balachandran, assistant professor of biomedical engineering.
In addition to Balachandran, who led the study, the research was conducted by Nasya Sturdivant, biomedical-engineering doctoral candidate; Jeffrey Wolchok, assistant professor of biomedical engineering; and partners at the FDA’s National Center for Toxicological Research in Jefferson, Arkansas.
