Using drugs that help eliminate oxygen radicals -- the toxic byproducts of metabolism -- scientists have extended the normal lifespan of the nematode worm C. elegans by approximately 50 percent. In addition, the scientists restored a normal lifespan to mutant worms that had a mitochondrial defect causing increased oxygen radical production and rapid aging. The findings were reported in the September 1, 2000 issue of Science.
