(LIVE SCIENCE) -- Could your pee reveal your youth? Or perhaps your advanced age? Scientists in China think so. In a study published today (Feb. 27) in the journal Frontiers in Aging Neuroscience, researchers say they have identified a natural chemical in urine that appears in higher concentrations as we age.
The researchers said the chemical may serve as a marker of your "biological age," or how fast you're aging, as opposed to your chronological age, which is based on your birth date. It's easy to detect in urine, too, they added.
The name of the chemical is a mouthful — 8-oxo-7,8-dihydroguanosine, or 8-oxoGsn for short. It's a byproduct of slow, lifelong damage to RNA, an important molecule that interacts with DNA to enable gene expression and to create proteins in the core of most cells.
