GREG BARSH: Experiments of nature are not just limited to humans. In fact, most experiments of nature are present in animals. And one of the best examples of this is the laboratory mouse that was used to discover a new hormone that's critical in determining how fat is produced and how the body responds to fat. And that new hormone is called leptin. And it turns out that there are rare mice that lack leptin and that lack the leptin receptor, and scientists didn't know that. What they saw was these fat mice, and somebody said, boy, these fat mice are really unusual; I wonder if we could figure out why they're fat. And pursuing that led them to discover this new hormone leptin and the receptor for leptin. And that's led to remarkable new insights in thinking about how to develop new treatments for diabetes and obesity in humans.
