New Tech for Sherlock Holmes
If Sherlock Holmes were real and around today, he would soon have a new technology tool to catch criminals. Based on DNA retrieved at the crime scene, detectives may soon be able to accurately sketch the suspect's face. That's because researchers have identified 15 genes that determine our facial features.
15 Key Genes
Scientists have provided a database with 3D images of faces and the corresponding DNA. Each face was subdivided into small modules. Then it was determined if any locations in the DNA matched the modules.
The modular division technique made it possible to check for an unprecedented number of facial features, resulting in unprecedented facial recognition accuracy. A team of university scientists from Stanford, Penn State and the University of Pittsburgh collaborated on this breakthrough technique to decode faces from retrieved DNA.
Exciting Potential Uses
This system not only paves the way for detectives trying to solve crimes. It also could help doctors with facial reconstructive surgery by using the patient's DNA. And it could help historians to reconstruct historic figures of long ago by using their DNA.
