If you stand in the lobby of the ӳý, it’s hard not to notice the movement of mammals above your head. A 17-foot wide mobile that hangs from the lobby’s ceiling includes the silhouettes of a chimpanzee, two-toed sloth, alpaca, little brown bat, elephant, dolphin, and more. Each of the depicted mammals gently swaying from the mobile’s branches has had its genome sequenced at the ӳý, the Genome Institute at Washington University, or the Baylor College of Medicine Human Genome Sequencing Center.
