Eew, where’s that smell coming from?

If you could ask a rat, it could locate the direction of the stench’s source in a single sniff, scientists report in a new study.

Rats accomplish this feat by effectively smelling in stereo: Each nostril operates independently of the other, sending different signals to the brain that are then computed to determine the direction of the odor.
