The Woman Who Tasted Shapes

In 1981, a chemist at a pharmaceutical company accidentally brushed her hand across her mouth and discovered one of the sweetest substances ever found — a compound she wasn't supposed to be making, in a lab where she wasn't supposed to be eating. But the story of sucralose is really a story about how the human body recognizes sweetness at all, and why scientists spent decades arguing over a receptor they couldn't see, couldn't isolate, and weren't even sure existed.

Every scientific breakthrough has a moment when everything changes forever. Join us as we dive deep into the exact moments when human understanding shattered and reformed, from the split second discoveries that rewrote textbooks to the quiet epiphanies that transformed civilization.
