Federal Project Grant Award Summary

The University of Memphis received a $467,837 Project Grant from the National Science Foundation (NSF), Division of Molecular and Cellular Biosciences, under the Biological Sciences program (CFDA 47.074), effective July 1, 2026 through June 30, 2029. This collaborative research project investigates how biochemical mechanisms that produce red carotenoid-based coloration in birds function as honest signals of individual health and vitality. The research integrates organismal biology with cell biology and biochemistry to examine the link between pigment production and fundamental cellular processes, including redox balance, thereby addressing a central question in evolutionary biology regarding how ornamental traits reliably convey information about health, performance, and reproductive potential.

Beyond the core research objective, the award supports workforce development and educational outreach through training of undergraduate students, graduate students, and postdoctoral researchers in interdisciplinary research bridging molecular biology and organismal biology. The project employs engineered cell lines via biotechnological approaches to test key hypotheses and includes K-12 outreach activities demonstrating scientific inquiry methods. The findings have broad implications for evolutionary biology, medicine, agriculture, and conservation, as the underlying principles governing how biological signals reliably convey information parallel cellular stress responses and organismal adaptation mechanisms across multiple scientific and applied domains.
