Due to a buildup of plaque which hardens arteries, atherosclerosis can lead to complications, such as heart attack or stroke. Researchers breed Japanese quail to increase their susceptibility to dietary-induced atherosclerosis to understand the role of fatty foods in cardiovascular disease.
The naked mole rat, a blind, nearly hairless rodent about the size of a mouse that lives underground, might provide the secret to reducing brain damage caused during a stroke. Thanks to these rodents, scientists know a lot more about how neurons survive in low-oxygen conditions. Armed with this new knowledge, they are working to find a way to prevent or minimize the impact of stroke, not only on seniors but also the 34% of people hospitalized for stroke who are under the age of 65.
