An Israeli company has created blood and saliva samples that contain fake DNA evidence, and the modification is undetectable in standard lab tests, reports Technology Review. Tel Aviv-based Nucleix demonstrated that it can replicate DNA from samples or produce new DNA based on a person’s genome sequence. The phony DNA goes into donor blood or saliva, scientific magic happens, and voila: fake crime scene evidence.
The company, conveniently, also has designed a proprietary test to distinguish between naturally shed DNA and its counterfeit cousin. All the same, this very falsified-evidence scenario has been “cited as a concern for those who make their genome sequence public,” Technology Review notes. It’ll be a concern for those who don’t choose to make their DNA public, too: Just this spring, the FBI expanded its collection of DNA to include people awaiting trial (who may well be acquitted) as well as detained immigrants.
