Mark Zuckerberg and his wife, Priscilla Chan, in 2016 founded the Chan Zuckerberg Initiative, an LLC that invests in charities and businesses that the couple believe can help the world and help cure diseases. Now the philanthropic organization is making its first acquisition: It has purchased Meta, an artificial intelligence startup for the medical community. Meta co-founder and CEO Sam Molyneux announced the deal in a Facebook post Monday. Terms of the deal were not disclosed. The startup uses an AI-powered search engine that helps researchers and doctors quickly find the most relevant information in a database of science research papers.
