Scientists at my alma mater, Leicester, and their fellows over at Warwick, have created artificial snot for electronic noses. The faux-mucus improves sensitivity of the faux-nose by a huge factor, allowing them to pick out a wider range of smells. This occurs because smells are actually dissolved in mucus and travel through it at different speeds, causing them to reach the nose receptors at variable rates, which alters processing capability. The fake snot has allowed their fake nose to now distinguish between subtly different odors such as milk and banana. [GT]
