Researchers in Northwest Arkansas and the River Valley have landed a combined $5.3 million in National Institutes of Health grants, with projects aimed at understanding how the body responds to stress and exercise.
The University of Arkansas and Arkansas Colleges of Health Education in Fort Smith recently announced the awards. Together, the grants point to a familiar wellness question with real-world stakes: why do people and cells respond so differently to the same stressors, and why do similar exercise programs lead to different outcomes for different people?
At the University of Arkansas, Jeffrey Lewis, an associate professor of biological sciences, received a $2 million NIH grant to study how cells vary in their responses to stress. His lab looks at the coordination and logic of stress-responsive regulatory networks, along with the genes that help cells maintain homeostasis. Lewis also studies how individuals perceive and respond to stress, using yeast as a model organism to explore genetic factors behind those differences.
The award runs for five years and is part of the NIH's Maximizing Investigators' Research Award, which is sponsored by the National Institute of General Medical Sciences. According to the university release, the funding will largely support additional research staff and graduate students, along with access to specialized equipment.
Lewis said the work could deepen understanding of conditions tied to abnormal stress responses, including heart disease, Parkinson's disease and cancer. For readers, that kind of research may sound far from daily life, but it connects to something many people know well: stress is not just a feeling, it is also a biological process that can shape health over time.
In Fort Smith, researchers at the Arkansas Colleges of Health Education Research Institute received a $3.3 million NIH grant to study why people can have different health and weight-loss outcomes from similar exercise programs. The project is led by Kyle Flack, an associate professor of pathology, pharmacology and physiology at ACHE's College of Osteopathic Medicine. The study will examine metabolic and behavioral factors that influence those differences.
Taken together, the grants show how much of today’s health research is focused on the practical questions people bring into everyday life: how the body adapts, why results vary, and what might help explain those gaps. For anyone trying to make sense of stress, exercise, or weight loss, that kind of work can feel especially close to home.
