🐱🔬 Scientists are taking a leaf (or should we say a whisker?) out of the housecat's playbook! Turns out, the intricate structure of a cat's nose could inspire next-gen gas chromatographs. Who knew CatNoseScience could be so purr-fectly enlightening?
Inside cats' noses, two very different pathways steer air through a complex system. The gas chromatograph, a ubiquitous scientific instrument used to separate and analyze different gasses, could learn a great deal from the cat’s nose,. As the first detailed study of the feline sniffer, it reveals a dual-channel system in the nose that the instrument could perhaps replicate.
The study mapped this complex network by CT-scanning the cadaver of a domestic short hair cat, revealing the intricate folds and passageways winding through the cat’s. Humans also have turbinates, but ours consist of a few simplistic folds, and we have the comparatively weak sense of smell to match. Dogs possess even more complex nasal passages than cats and humans, allowing them to ruminate on a scent with great focus.Researchers discovered that with cats, the dual streams serve different purposes. The first channel goes low and relatively slow and spreads through the turbinates before eventually reaching the olfactory region. This gradual pathway resembles a gas chromatograph with a long tube designed to detect more chemicals at a slower rate.
Once air arrives at the olfactory region, it circulates through parallel channels that make the most of each breath.
