When working with human afflictions such as hypothyroidism and diabetes, researchers find it beneficial to study model organisms that can exhibit the same conditions. Animals such as mice and turtles, for example, can provide insight about the biological traits and medical conditions they share with humans. This summer Melanie Hundt ’13, Nicole Nietlisbach ’13 and Max Vaickus ’12 examined hypothyroidism and diabetes in mice and tested for the hormone ghrelin in turtles. The students worked with Professor of Biology David Gapp.
