This video was produced for Inside Science TV, part of a news organization supported by the American Institute of Physics, during my summer internship with Bytesize Science. (By the way, Bytesize Science is now Reactions on both Youtube and Twitter.) Anyway, I had a great time interviewing the researchers at NIH and producing the animations for this video. Extra credits go to Sean Parsons and Kirk Zamieroski for their help. And if you want more of the story, read Ed Yong’s take on it here.
