Scientist Uncovers Internal Clock Able to Measure Age of Most Human Tissues
"Everyone grows older, but scientists don't really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process. Published in the Oct. 21 edition of Genome Biology, the findings could offer valuable insights into cancer and stem cell research"

UCLA scientists may have found "biological clock" in genes
"Researchers have discovered a "biological clock" embedded in the human genome that can indicate how old a person's tissues and cells really are. The hope is with this clock, they may eventually find a way to slow or reverse aging in some parts of the body."
