Roundworms (IMAGE) MDI Biological Laboratory Caption The roundworm, C. elegans, is a popular model in aging research because its short lifespan allows scientists to quickly assess the effects of anti-aging interventions, including genetic manipulation and drug therapies. Scientists at the MDI Biological Laboratory used C. elegans as a model to identify markers of healthy aging. The study will help scientists assess the tradeoffs between lifespan and health span in humans.
