In Please Explain, we set aside time every Friday afternoon to get to the bottom of one complex issue. We'll back up and review the basic facts and principles of complicated issues across a broad range of topics — history, politics, science, you name it.
On today's Please Explain, we get nosey with smell. Biophysicist Dr. Luca Turin and psychobiologist Dr. Charles Wysocki explain what odors are, how our noses work, and what kind of information humans can gather by smell.
Host Leonard Lopate lets you in on the best conversations with writers, actors, ex-presidents, dancers, scientists, comedians, historians, grammarians, curators, filmmakers, and do-it-yourself experts.
