Last, but certainly not least, they are able to survive at levels of oxygen so low that they would be fatal to other animals. This week, researchers at the University of British Columbia showed that naked mole rats do this in a way that is completely unique among mammals. The insight may one day lead to new ways to prevent or treat human conditions like stroke.
