Scents and Sensibilities: The Invisible Language of Smell

What does fear smell like? Love? Can we use scent to control behavior? Do humans really sense pheromones? What if you could diagnose diseases just by smelling them? And exactly how does our brain convert floating organic molecules into chemical signals that our brain processes as odor? Over hundreds of thousands of years, our ancestors learned to encode specific scents with information that saved their lives. Many species still depend heavily on smell for their daily survival. Described as “the most direct pathway to the brain,” olfaction is subconscious, pre-cognitive, and emotional. Juju Chang hosts a discussion with Leslie Vosshall, Consuelo De Moraes, Sissel Tolaas, and Avery Gilbert for a “scent interactive” panel about the fascinating science of smell and how it offers a powerful window into our brains, behaviors, emotions, and communication. The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
