Google's latest big idea is called "Baseline Study"—an effort to catalog the DNA of thousands of healthy people, along with their blood, urine, saliva, breath, and tears. Over time, the project may detect the hallmarks of disease years earlier than we currently can, says project collaborator Sam Gambhir, of Stanford University. But gathering data is only the first step. The key, says Dartmouth College’s Jason Moore, is asking the right questions of that information.
