Conventional forensic DNA analysis matches samples gathered from crime scenes and compares them with those of people identified in an investigation or in a database. Increasingly, however, investigators are building physical profiles of individuals on the basis of their DNA alone. For instance, six genetic markers can indicate whether a person has blue or brown eyes1.

In a paper published online today in Current Biology2, researchers based in the Netherlands report a genetic signature for a person's age — to within a decade or so — in a type of white blood cell known as a T cell. Other means of accurately determining a person's age rely on skeletal remains. But, in "most cases you don't have bones or teeth you simply have stains", says Manfred Kayser, a geneticist at Erasmus University Medical Center in Rotterdam, the Netherlands, and a co-author on the paper.
