Eyes: a window to human aging?

In what is believed to be the first study of its kind, researchers from Boston University School of Medicine (BUSM; MA, USA) have developed a specialized eye scanner that can detect and track biological aging in living humans. This non-invasive, objective technique could pave the way for a tool that assesses and tracks molecular aging in humans. These results have been published in the Journal of Gerontology: Biological Sciences. It is widely acknowledged that individuals age at different rates. Though chronological aging tells us how long we have been alive, there is currently no universally accepted measure of molecular aging...
