The race set off late in the afternoon on Friday at Massachusetts General Hospital: 15 competitors from across the world gathered for a neck-and-neck journey through a twisting maze, with a long straightaway that was the perfect setup for a sprint finish. It was the World Dicty Race, a competition that unfolds on a microscope slide carved with tiny channels for a track. Daniel Irimia, assistant professor of surgery at Massachusetts General Hospital, organized the contest. Michael Myre, instructor in neurology at Massachusetts General Hospital, won fourth place.
