2015 NIH Director’s Early Independence Award

Sports SponsorsLast September, the National Football League struck a deal with Frito-Lay that allowed the company to produce limited-edition bags of Tostitos tortilla chips, with each package bearing the logo of one of 19 featured NFL teams. Several months earlier, Major League Baseball announced that Nathan’s Famous would be its first-ever official hot dog. Now the first-ever comprehensive analysis of such food and beverage sponsorships by major sports organizations shows just how pervasive these deals are. The confusing messages they send about physical fitness and healthy eating habits can’t be helping our national problem with obesity [1].

Among the 10 sports organizations that young viewers watch most, from the NFL to Little League, the NIH-funded research team identified dozens of sponsors and hundreds of associated advertisements promoting food and beverage products. The vast majority of those ads touted unhealthy items, including chips, candies, sodas, and other foods high in fat, sodium, or sugar, and low in nutritional value.

Those findings are especially concerning in light of the latest figures from the National Health and Nutrition Examination Survey (NHANES), co-supported by NIH [2], It shows that, despite long-standing public health efforts to curb the obesity epidemic, more than 18 percent of young people in America remain obese. Among adults, the picture is even more discouraging: nearly 40 percent of American adults were obese in 2015-2016, up from about 34 percent in 2007-2008.

While earning her Ph.D. in clinical psychology, Dylan Gee often encountered children and adolescents battling phobias, panic attacks, and other anxiety disorders. Most overcame them with the help of psychotherapy. But not all of the kids did, and Gee spent many an hour brainstorming about how to help her tougher cases, often to find that nothing worked.

What Gee noticed was that so many of the interventions she pondered were based on studies in adults. Little was actually known about the dramatic changes that a child’s developing brain undergoes and their implications for coping under stress. Gee, an assistant professor at Yale University, New Haven, CT, decided to dedicate her research career to bridging the gap between basic neuroscience and clinical interventions to treat children and adolescents with persistent anxiety and stress-related disorders.

Dmitry Lyumkis

Dmitry Lyumkis

When Dmitry Lyumkis headed off to graduate school at The Scripps Research Institute, La Jolla, CA, he had thoughts of becoming a synthetic chemist. But he soon found his calling in a nearby lab that imaged proteins using a technique known as single-particle cryo-electron microscopy (EM). Lyumkis was amazed that the team could take a purified protein, flash-freeze it in liquid nitrogen, and then fire electrons at the protein, capturing the resulting image with a special camera. Also amazing was the sophisticated computer software that analyzed the raw 2D camera images, merging the data and reconstructing it into 3D representations of the protein.

The work was profoundly complex, but Lyumkis thrives on solving extremely difficult puzzles. He joined the Scripps lab to become a structural biologist and a few years later used single-particle cryo-EM to help determine the atomic structure of a key protein on the surface of the human immunodeficiency virus (HIV), the cause of AIDS. The protein had been considered one of the greatest challenges in structural biology and a critical target in developing an AIDS vaccine [1].

Now, Lyumkis has plans to take single-particle cryo-EM to a whole new level—literally. He wants to develop new methods that allow it to model the atomic structures of much smaller proteins. Right now, single-particle cryo-EM has worked with proteins as small as roughly 150 kilodaltons, a measure of a protein’s molecular weight (the approximate average mass of a protein is 53 kDa). Lyumkis plans to drop that number well below 100 kDa, noting that if his new methods work as he hopes, there should be very little, if any, lower size limit to get the technique to work. He envisions generating within a matter of days or weeks the precise structure of an average-sized protein involved in a disease, and then potentially handing it off as an atomic model for drug developers to target for more effective treatment.

Elaine Hill

Elaine Hill

A few years ago, Elaine Hill was a doctoral student in applied economics at Cornell University in Ithaca, NY, studying maize markets in Uganda [1] and dairy supply chains in the northeastern U.S [2]. But when fracking—a controversial, hydraulic fracturing technique used to produce oil and natural gas—became a hot topic in the Finger Lakes region of upstate New York, Hill was motivated to shift gears.

After watching a documentary about fracking, Hill decided to search for scientific evidence on its possible health effects, but found relatively little high-quality data. So, she embarked on a new project—one that eventually earned her a Ph.D.—to evaluate what, if any, impact fracking has on infant and child health. Now, supported by a 2015 NIH Director’s Early Independence Award, Hill is pursuing this line of research further as an assistant professor of Public Health Sciences at the University of Rochester School of Medicine and Dentistry, Rochester, NY.

When bears, bats, and other animals prepare to hibernate, they pack on fat at an impressive pace to almost double their weight. As they drift off into their winter slumber, their heart rates, breathing, and metabolism slow dramatically. Hibernating mammals can survive in this state of torpor for a period of weeks or even months without eating or drinking anything at all!

It’s a fascinating and still rather mysterious process—and one that William Israelsen of The University of Texas Southwestern Medical Center, Dallas, thinks may yield intriguing insights with implications for human health. A recipient of a 2015 NIH Director’s Early Independence Award, Israelsen plans to use a little-known mouse species to study hibernation in the laboratory at a level of detail that’s not possible in the wild. He especially wants to learn how hibernating animals shift their metabolic gears over the course of the year, and what those findings might reveal about human obesity, cancer, and other health conditions.
