New York artist Kunié Sugiura created the photogram of MIT biologist Phillip Sharp that appears on our cover and on p. 36 during a visit to his lab in January. Sugiura, who creates camera-less photographs by placing her subject in front of photographic paper and exposing them to light, says she asked Sharp to “bring some things that represent who he is and what he does” to the sitting. He held the string to represent RNA splicing, for which he won a Nobel Prize in 1993.
