Humans rely on our senses to tell us about the world. Which way is that waterfall? Is it day or night? Is that food fresh or spoiled?
Such questions are harder to answer if our sensory systems can’t detect the sound of rushing water, the shimmer of moonlight or the odor of spoiled milk. Prior to this week, the Nobel Committee for Physiology or Medicine had recognized important advances in our understanding of how sensations are detected in three sensory systems: hearing, vision and smell.
