The nonprofit Biohub, led by Mark Zuckerberg and Priscilla Chan, is investing $500 million to create better AI simulations of the human body. The aim is to produce more useful models based on more data and compute. The money will be used to aid in curing all human disease through the intersection of AI and biology. Of the total cost, Biohub will spend $400 million on its own work and $100 million on assisting others. Partners include chipmaker Nvidia, leading research organizations such as the Allen Institute, the Human Cell Atlas and the Human Protein Atlas. However, reaching the ambitious goal of curing all disease will likely take more than five years.
