Sandra Hines, University of Washington Car and truck exhaust fumes that foul the air for humans also cause problems for pollinators. In new research on how pollinators find flowers when background odors are strong, University of Washington and University of Arizona researchers have found that both natural plant odors and human sources of pollution can conceal the scent of sought-after flowers. When the calories from one feeding of a flower gets you only 15 minutes of flight, as is...

Alan McStravick for redOrbit.com - Your Universe Online The sense of smell in humans has undergone many permutations as we have traveled through evolutionary time. It was once believed that each successive version of our olfactory ability was weaker than the last. Scientists claimed as our sense of sight became ever greater and required more of our energy, our sense of smell suffered. They cited the gradual reduction of our noses paired with the movement of our eyes closer to the middle of...

Faces Are More Attractive When Ambient Odors Are Pleasant: Study
2014-05-30 14:16:54

Alan McStravick for redorbit.com - Your Universe online Unilever, the multinational corporation behind such personal care products as Axe body spray, Dove soap and Surf laundry detergents, has funded a research study conducted by the Monell Chemical Senses Center in Philadelphia, PA. In the study, it was determined that a subject was deemed more or less attractive dependent upon the quality of the ambient odor. The study actually tested two hypotheses in relation to the relative...

To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor. The complex and diverse olfactory system they build remains adaptable, but a new study in the journal Science shows that the system's flexibility, or plasticity, has its limits. Working in mice, Brown University scientists found that the fundamental neural wiring map between the nose and the brain becomes established in a critical period of early development and then...

Stowers investigators reveal a developmental switch in targeting capacity of olfactory neurons The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor and all neurons with the same receptors are connected to the same spot, a glomerulus, in the brain. This convergence, or wiring pattern, is often described as an...

Max Planck Institute for Chemical Ecology Odorant receptors of recent insects evolved long after insects migrated from water to land. An insect’s sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at the Max Planck Institute for Chemical Ecology, many proteins involved in the highly sensitive odor perception of insects emerged...

Nose
2013-03-05 14:47:26

The nose is the organ that extends outward in the middle of the face between the eyes and mouth. Formation and Orientation The shape and look of the nose is dependent on the ethmoid bone and the nasal septum which is the cartilage that separates the two nostrils. The evolutionary hypotheses of nose development in humans propose that noses are alterations of the angles of the skull because of bipedalism. Because of the change in diet that has come with modern time and the change of...
