Zuckerberg and Priscilla Chan are committing $3 billion over the next 10 years to accelerate basic scientific research. Zuckerberg and Chan have spent the past two years speaking to scientists and other experts to plan the endeavor. "I've been with families where we've hit the limit of what's possible through medicine and science," Chan said. At the time, this was valued at more than $45 billion worth of Facebook stock, which the couple transferred to the Chan Zuckerberg Initiative. Zuckerberg and Chan often draw comparisons to Bill and Melinda Gates, whose philanthropic work also focuses on health and education.
