Imagine the possibilities if we open-sourced all our DNA—or at least tweaked consent forms to allow opt-ins for sharing genetic info with all scientists. John Wilbanks, chief commons officer at Sage Bionetworks (which offers a database of public genomes), says the Human Genome Project covers only what we have in common. "What makes us unique is what makes us respond differently to drugs, to food, to environment, to disease," he says. "A large database of individual genomes is going to be vital to help us understand how our variations make us healthy or not." Genomic research today, he says, is like doing a Google search on only a handful of Web pages. With a few hundred thousand genomes, we would better understand how illnesses and drugs behave differently from person to person. Put aside the fear. It's time to let science run free with our DNA.
