MU biologist Rex Cocroft studies communication, something crucial to life at many levels, as it occurs within a cell, between cells, and between organisms within social groups. "Once we reach the level of communication between individuals," waxes Cocroft, "not only is there the fascinating intellectual challenge of studying communication, but there is also this tremendous aesthetic appeal…. The signals themselves are often beautiful—the songs of whales, the colors of butterfly wings, the scents of flowers." His first calling was that of a musician, so it's perhaps no surprise that Cocroft was drawn to this aspect of biology, and no accident that he enjoys being at MU. "I love it here [in Missouri] in the late summer," he says, "when the katydids and the cicadas are out and there's this din of calling insects."
