Further Explorations of the Biochemistry of 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 »

(Found via Transhumanity). Scientists are making good progress in uncovering the biochemical mechanisms of cellular aging, as reported by Cancer Research UK. This has implications for cancer diagnosis and treatment, as well as for aging research. The work builds on recent studies involving telomeres, protective caps on the end of chromosomes. Scientists have now uncovered the mechanisms that prevent a cell from further dividing once telomeres have worn away. This is an important step forward, hopefully the first of many more.
