Google[x], a semisecretive branch of the company most famous for its search engine, hosted an invitation-only summit on cancer immunotherapy to see how it might help speed discovery in the burgeoning field. Andy Conrad, head of the Google[x] life sciences program—which now has a team of 100—urged the participants to think big, along the lines of "10x, not 10%." For 2 days, the Google[x] team members mixed it up with leading immunologists, oncologists, materials scientists, imaging specialists, and engineers, and in the end they came up with two top-priority projects that the company plans to help fund and coordinate.
