摘要:As we get older we become more likely to get sick and, eventually, die. Although the underlying pathologies and major causes of death in elderly humans have been well documented, much less is known about the events leading to age-related death in the fruit fly Drosophila melanogaster- one of the premier model systems in aging research. What is the underlying pathology that limits the lifespan of a fly. Is it possible to predict when a fly will die based upon a loss of organ function. What accounts for the enormous variation in lifespan amongst individual flies within a population
