Talk about Dr. Jekyll and Mr. Hyde. Misfolded proteins known as prions cause mad cow disease and other fatal neurodegenerative illnesses. But in their properly folded form, the proteins may be important to survival, helping mice and other animals keep their sniffing skills sharp, new research shows.
Prions get the bad reputation--and the lion's share of research attention--but interest in the normal form of prion proteins is increasing

Weight gain and moodiness top the list of the unpleasant side effects of birth control pills. But could the pill also desensitize a woman's sniffer? New research suggests that oral contraceptives can reduce a woman's ability to smell the best mate. Although birth control can't be blamed for every bad relationship, the findings could help explain how people find their ideal love.
Most guys splash on a little cologne before a first date, but past research shows that their natural scent may be the better attractant

Hawks are famous for their sharp vision, and owls are renowned for their keen hearing, but birds rarely get much credit for their sense of smell. That may change thanks to the first analysis of olfactory genes in a wide range of avian species. Birds, it turns out, may be better smellers than we thought.
Researchers interested in bird behavior have tended to focus on their flashy mating displays, melodious songs, and other talents, leaving the avian sense of smell largely unexplored 
Olfactory Cilia Architecture Is Remodeled through Sensory Signaling-Dependent Pathway in C. elegans

Here the researchers show that sensory signaling is required to maintain the architecture of the specialized AWB olfactory neuron cilia in C. elegans. And their results suggest that compensatory mechanisms in response to altered levels of sensory activity modulate AWB cilia architecture, revealing remarkable plasticity in the regulation of cilia structure. 
Sensory Signaling-Dependent Remodeling of Olfactory Cilia Architecture in C. elegans

This article reveals an unexpected level of interplay between signaling activity and structural organization in primary cilia in C. elegans olfactory neurons.
And it suggests that compensatory mechanisms in response to altered levels of sensory activity modulate AWB cilia architecture, revealing remarkable plasticity in the regulation of cilia structure. 


Researchers use mouse urine to construct artificial noses

No, it's not left over from the vivarium. They selected mouse urine because of its high concentration of good-sized proteins. The artificial noses, as they're called, may eventually be used to detect drugs and explosives.

"Together, these results indicate that mGluR1 plays a critical role in controlling information flow through the AOB and suggest that mGluR1 may be an important locus for experience-dependent changes in synaptic function.
