Mirroring the mechanisms that make human faces and bodies—and those of many multicellular organisms—symmetrical, bee colonies build symmetrical nests when they are placed on either side of a double-sided comb. The finding, published in Current Biology, extends examples of symmetry in biology to the behavior of communities and the architectural structures that they build.
