Super Sniffers: Scent Dogs Excel in COVID-19 Detection

New research suggests that scent dogs may provide a faster and more efficient way to detect COVID-19, even outperforming conventional RT-PCR tests. In studies involving over 31,000 samples, dogs were able to identify COVID-19 in symptomatic, pre-symptomatic, and asymptomatic individuals, as well as detect new variants and long COVID.

Nose Picking Could Increase Risk for Alzheimer’s and Dementia

The Chlamydia pneumoniae bacteria can travel directly from olfactory nerve in the nose and into the brain, forcing brain cells to deposit amyloid beta and inducing Alzheimer's pathologies. Researchers say protecting the lining of the nose by not picking or plucking nasal hairs can help lower Alzheimer's risks.

Sniffing Out the Brain’s Smelling Power

In the olfactory system, tufted cells are better at recognizing smells than mitral cells. Tufted cells are one of two parallel neural circuit loops that help the brain process different odor features. The findings shed light on how the brain takes in sensory information that influences behavior and emotion.
