Sean Parker to Set Up Cancer Immunotherapy Center

The co-founder of Napster and founding president of Facebook has set his sights on a new kind of innovation: cancer immunotherapy research.

Sean Parker has announced he will donate $250 million to establish the Parker Institute for Cancer Immunotherapy. This field of research focuses on fighting cancer cells by triggering "the immune system’s ability to seek out and destroy invaders," as TIME explained in a recent cover story.
