When I wrote about artist Heather Dewey-Hagborg, who had been taking DNA samples from the street and turning them into 3D printed portraits, I had to tell a friend that the artist’s portraits were only rough estimates of the people from whom the DNA was extracted. The technology, I said, was just not quite at the point where you could take a piece of DNA evidence and recreate, with accuracy, a complete image of that person’s face. But that doesn’t mean that researchers aren’t trying. A team at Penn State has just published a paper pushing further towards extrapolating an entire human face from a DNA sample.…
