Aside from the gorgeous new 12-inch MacBook Air, the part of today’s Apple keynote that excited me the most was the announcement of what Apple is calling ResearchKit, a new open-source iOS software framework designed to crowdsource volunteers for medical research studies.
Using the tool, researchers can tap into Apple’s massive iPhone user base to recruit people for medical data-gathering. Users sign up with a digital signature, and can then instantly begin recording data.
