The World

A third of men who take paternity tests end up finding out that they’re not really the father. And just as stricter federal rules are holding baby daddies more accountable, the science of proving paternity is getting cheaper, easier and more reliable.

We also speak to Ruth Padawer, who writes about this in Sunday’s New York Times magazine.
