Studying "Obese" Whales to Understand Human Obesity
How do mammals get fat and stay fat? Specifically, how do whales do it? That’s what researchers in UA Biology are trying to finout out. To do so, Hope Ball, a PhD student in the Integrated Biosciences program is looking at tiny protein called leptin that’s involved in how the body regulates how much it eats and how much energy it burns. The goal for mammals is typically to find a balance between food intake and energy burn. Whales, and other obese mammals, have found a way to build large fat stores despite this balance but rather than being obese they appear to be healthy and happy as fat mammals. Learn More
