Educating Truckers on the Go
By Todd Dills
When UAB nurse practitioner Karen Heaton, Ph.D., met her husband, a long-haul owner-operator, she discovered that the nation’s truckers carry a host of unmet health needs along with their cargo. In particular, “I was struck when I read that individuals who are sleep-deprived and driving have the same levels of impairment as those who are intoxicated,” Heaton says.
Now Heaton, an assistant professor in the UAB School of Nursing, is testing an online intervention program focusing on sleep and fatigue management among the nation’s truck drivers. She has been visiting industry trade shows and reaching out to trucking companies and associations to recruit drivers to participate in the study, which is funded by the National Institute of Occupational Safety and Health.
Heaton’s goal is to arm truck drivers with the information they need to recognize the importance of sleep for safety, well-being, and, ultimately, baseline human health. If the online model proves to be effective in reinforcing the basics of sleep among participants and encouraging them to modify their behavior, Heaton hopes that trucking companies will add it to driver-safety training. The program could even become part of the first health-related requirements for Federal Motor Carrier Safety Administration (FMCSA)-regulated training, something every new long-haul driver would take in the interest of public safety.
Energetics Research Could Provide Clues
By Jeff Hansen
Is obesity an adaptive response to poverty? Playmobil people explain in under a minute in this latest edition of Science in 60 Seconds.
In the summer of 2011, UAB researcher David Allison, Ph.D., often hiked up the Blue Trail of Oak Mountain State Park to Peavine Falls.
It turns out that he was starting a journey down an unconventional path.
Accompanied by postdocs, graduate students, family, and his dog, Gigi, Allison used the hikes to launch wide-ranging scientific give-and-takes, dreaming up hypothetical experiments and asking “what-if” questions about the origins of obesity.
In turn, those questions have led to one of UAB’s most unusual grants—an $8-million, five-year Transformative Research Award from the National Institutes of Health, the first ever for the university. These grants, the NIH says, target “exceptionally innovative” research projects that “tend to be inherently risky.” Loosely speaking, the funding enables researchers to gamble on big-payoff ideas.
Perception Is Everything
The ambitious idea from Allison’s team proposes that an organism’s perception of its environment has the power to make the organism change how quickly it ages (even though it may not be aware it is doing so). Furthermore, perception of the environment could make an organism alter its efforts to seek food and store more of that food as energy—in the form of caches of nuts and berries for birds, for example, or body fat in humans and mice.
Body fat is a key term, because ultimately, this UAB-led research seeks to understand one of the great public health puzzles of the past 20 years—why America has seen an explosion in life-shortening obesity. In Alabama, one of the fattest states, a higher rate of obesity among poorer groups of people creates health disparities. Obesity also increases rates of some cancers.
These problems are a focus for the Office of Energetics in the UAB School of Public Health, which debuted in July 2011 and is headed by Allison, a psychologist who also serves as the school’s associate dean for science. Energetics research looks at why and how biological organisms acquire, store, and use metabolizable energy—which includes food and body fat.
Foreign Language Learning Opens Doors At Home and Abroad

From Spanish to Chinese to Arabic, UAB students are using their language skills to further diplomacy across the globe and to help businesses around the corner.
“Society is changing rapidly and drastically,” says Lourdes Sánchez-López, Ph.D., associate professor of Spanish in the Department of Foreign Languages and Literatures. “Students prepare furiously for a globalized job market that is open to anyone in the world. Often, the decisive factor for an employer is the multi-linguistic and multicultural qualifications of applicants.”
Many students are attracted to languages for reasons beyond their resumes, of course. “I first enrolled in Chinese class because I was interested in the character-based writing system,” says junior Devin Thorne. “Writing characters is like drawing for me.” Thorne is one of the six UAB students who have won the U.S. State Department’s prestigious Critical Language Scholarship (CLS) in the past three years.
