Sean Parker is known for many things: co-founding Napster, joining Facebook in its early days, starting charities and creating his share of technology startups. If all goes well, though, he'll also add "helped cure cancer" to that list. He just founded the Parker Institute for Cancer Immunotherapy, a $250 million effort to fight cancer by relying on the body's immune system. The organization will unite six universities (covering 40 labs and over 300 scientists), encouraging them to share research rather than compete. As Parker puts it, humanity is on the "bleeding edge" of what you can do with synthetic biology... it might just need a nudge to turn those findings into real-world treatments.
