CLOCK THAT MEASURES AGING IN HUMAN DNA FOUND

In a step towards unraveling the mystery of aging, a US scientist has discovered a human body clock tucked away in body's DNA. It measures the age of cells, tissues and organs.

Steve Hovarth of the University of California, Los Angeles found that different parts of the body were aging at different speeds - some faster, others slower. Significantly, diseased organs showed ages many years in ahead of the rest of the normal body. Hovarth's study is reported in the scientific journal Genome Biology on Monday.
