Science Finds the DNA Body Clock

DNA

This one should go a long way toward extending life expectancy. Steve Horvath, professor of genetics and biostatistics at the University of California in Los Angeles has found the human "body clock" in DNA. According to the Guardian:
"A US scientist has discovered an internal body clock based on DNA that measures the biological age of our tissues and organs.

The clock shows that while many healthy tissues age at the same rate as the body as a whole, some of them age much faster or slower. The age of diseased organs varied hugely, with some many tens of years "older" than healthy tissue in the same person, according to the clock.

Researchers say that unravelling the mechanisms behind the clock will help them understand the ageing process and hopefully lead to drugs and other interventions that slow it down."

So, a lot of work still to go. Finding a watch is a lot different from understanding how all the gears work. On the other hand, you'll never understand how the parts work if you don't have a watch.
