On October 4, physiologist David Julius and neurobiologist Arden Patapoutian were awarded the Nobel Prize in Physiology or Medicine for their work on temperature, pain, and touch perception. Julius researched the burning sensation people experience from chilies, and identified an ion channel, TRPV1 that is activated by heat. Julius and Patapoutian then separately reported on the TRPM8 ion channel that senses menthol’s cold in 2002. Patapoutian’s group went on to discover the PIEZO1 and PIEZO2 ion channels that are involved in sensing mechanical pressure. The Nobel Committee wrote that the pair’s work inspired further research into understanding how the nervous system senses temperature and mechanical stimuli and that the laureates “identified critical missing links in our understanding of the complex interplay between our senses and the environment.”
