Facebook founder Mark Zuckerberg and his wife, Dr. Priscilla Chan, on Wednesday announced a $3 billion initiative centered at UCSF’s Mission Bay to help cure or better manage disease. The new initiative, Chan Zuckerberg Science, is designed to help bring scientists and engineers together, build new tools and technologies and foster a movement to help fund more science, he said. The first project for Chan Zuckerberg Science is the Biohub, a $600 million project centered at UC Berkeley and UCSF to develop new tools to help better understand and treat disease.
