As part of his series of conversations on tech and society, Mark Zuckerberg sat down with Dr. Joe DeRisi and Dr. Steve Quake, who lead the Chan Zuckerberg Biohub, a nonprofit research center that brings together scientists and engineers from Stanford, Berkeley and UCSF. They talked about how technology is accelerating health research, the new advancements they’re most excited about, how to restore faith in science and what wearables will mean for the future of health.
