Molecule Can Measure Aging in Cells

This is big news, really. Researchers at the Unviersity of North Carolina have found a way to measure the age of a cell. As cells age, they increase the expression of a protein called p16INKa. Now there is a way to measure how old a cell is. Cellular age is critical in figuring out how behaviors, genetics and environment interact to age a person. If further testing shows promise, there may be a day when your "real age" is determined not by your chronilogical age or by a survey, but by the actual aging of your cells.
