In January 2013 I wrote about DNA artist Heather Dewey-Hagborg of New York, who uses anonymous DNA samples retrieved from sources like chewing gum and loose hairs to recreate the faces of the people who left them behind. Her work is a commentary on genetic privacy and now Dewey-Hagborg is out with two products that are meant to help you keep your discarded DNA to yourself: "Erase," which deletes most of the DNA you leave behind, and "Replace," which obfuscates the rest. They each come in a pocket-size spray bottle, perfect for a DNA-strewn night on the town, and Dewey-Hagborg introduces them in an ominous video (starring herself) that presents them as a kind of citizens' defense against the looming DNA surveillance state. By email, she explained that Erase is a "surface decontaminant," similar to bleach spray, that destroys 99.5 percent of the DNA you leave behind on something like the rim of a wine glass, while Replace is "a solution of custom amplified DNA," which, when sprayed over your own DNA, creates so much genetic noise that a DNA snoop won't be able to tell who's who. The two products are available starting in June for $99 for the pair, and Dewey-Hagborg explains that "this is the first product, the first prototype, in what I foresee being a whole new class of product."
