This small subterranean catfish sees the light of day and human observers only rarely, when it turns up in springs, wells and flooded rice paddies in the Western Ghats mountain region of Kerala, India. Scientists at the Academy of Natural Sciences of Drexel University have recently provided a detailed description of this fish's bizarre bone structures.

      A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new study led by Drexel professor Sean O'Donnell, PhD, indicates that the brain regions involved in sensory perception also develop differently in these castes, according to the different behavioral reliance on the senses.
