More On Mitochondria And Aging

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

You may recall that scientists in Sweden recently provided hard proof for the mitochondrial theory of aging: "These findings strongly support the idea that mutations in mitochondrial DNA can cause at least some features of aging." This long article from Science News Online gives a good account of this research, the underlying science, and where we should expect follow-on research to go from here. "The mice engineered by Larsson and his colleagues should invigorate research into the processes of aging." More scientists are now thinking about how to better classify the effects of mitochondrial mutations, prevent them, or prevent the resulting damage. Good!
