This wraps up our three-part series Blood, Sweat, and Tears. First, how it feels to lose your ability to cry; then why onions bring on the waterworks. Read the full description.

Asset_upload_file496_76789_thumbnail_small Dry your eyes: Distillations has returned with the final episode of our three-part series Blood, Sweat, and Tears. These vital fluids are more than just bodily emissions—they can also be considered the purest expressions of our humanity, at least metaphorically speaking. But of course, our focus is science, so for our third installment we parse the chemistry of tears. First reporter Douglas Smith talks to a friend who lost the ability to make tears. She can't cry even when her body clearly desires that catharsis. Then executive producer Jennifer Dionisio gets to the bottom of those pesky onion tears—including how one scientist is trying to bioengineer a no-cry version.
