Snot has the power to alter scents

Mice studies show sense of smell can be modified by mucus

A rose sniffed through a snotty nose may not smell so sweet. Enzymes in mice’s nasal mucus transform certain scents before the nose can detect them, a new study finds. The results, published December 1 in the Journal of Neuroscience, show that lowly mucus may feature prominently in the sense of smell.
