A new saliva test developed by geneticists at the University of California, Los Angeles, reveals a person’s age within five years, a finding that could have many applications in medicine, at crime scenes, and more.
“With just a saliva sample, we can accurately predict a person’s age without knowing anything else about them,” says principal investigator Dr. Eric Vilain, a professor of human genetics, pediatrics and urology, in a UCLA news release.
Too bad we didn’t have this technology about a decade ago, it would have helped solve this mystery.
