The light-sensing protein rhodopsin, packed inside the eye’s photoreceptor cells, is critical for sensing temperatures, scientists report. Rhodopsin, one of the most studied sensory receptors, had been thought to function solely in the eye as a light receptor, but now investigators at Johns Hopkins University have found that it is used by fruit fly larvae and other organisms to distinguish between slight temperature differences. The research team identified this role for rhodopsin while studying the process that results in the activation of a temperature-sensor protein called...Read full article
