Unexplainable is a new podcast from Vox about everything we don’t know. Each week, the team looks at the most fascinating unanswered questions in science and the mind-bending ways scientists are trying to answer them. New episodes drop every Wednesday. 

This episode: Scientists still don't know how the sense of smell works. But they're looking at how powerful it is — dogs can actually sniff out cancer and many other diseases — and they're trying to figure out how to reverse-engineer it. In fact, one MIT scientist may have built a robot nose ... without completely understanding how his invention works.
