Origins Of Our Smell Cells Pinpointed By Scientists
2013-03-26 08:09:14

redOrbit Staff & Wire Reports - Your Universe Online Biologists at the California Institute of Technology (Caltech) have identified the origin of olfactory nerve cells, finding that neural-crest stem cells — multipotent, migratory cells unique to vertebrates that give rise to many structures in the body — play a key role in building olfactory sensory neurons in the nose. When human noses detect a scent, two types of sensory neurons are at work. These neurons are...

Insect odorant receptors regulate their own sensitivity. Highly developed antennae containing different types of olfactory receptors allow insects to use minute amounts of odors for orientation towards resources like food, oviposition sites or mates. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now used mutant flies and for the first time provided experimental proof that the extremely sensitive olfactory system of fruit flies – they are able to...

Impulsive Eating Triggered By Neural Pathway
2013-03-01 04:41:35

redOrbit Staff & Wire Reports - Your Universe Online The discovery of a neural pathway in the brain of an insect that has been linked to pleasure eating could shed new light on the impulsive consumption of food by men and women, claim researchers from one US university. As part of their study, University of Georgia (UGA) associate professor of cellular biology Ping Shen and colleagues presented fruit fly larvae that had already been fed with appetizing smells. In turn, those...

Mosquitoes Become Less Repelled By DEET After First Exposure
2013-02-21 15:11:59

Brett Smith for redOrbit.com - Your Universe Online The insect repellant DEET has been widely used to keep mosquitoes away and has been invaluable in countries affected by outbreaks of disease such as malaria and dengue fever, both transmitted by the annoying pest. However, a new report in the open-access journal PLoS ONE finds that mosquitoes are less repelled by DEET after an initial exposure. According to the team of U.K. researchers who conducted the study, mosquitoes will ignore...

Stereo Sniffing Helps Common Moles Detect Their Food
2013-02-06 15:05:32

[Watch Video: Testing Stereo Sniffing Moles] Alan McStravick for redOrbit.com - Your Universe Online Almost all mammals, including us humans, can see and hear in stereo. But which other of our senses might utilize a 3D approach for more effective operation? It turns out a new study, published yesterday in the journal Nature Communications, has found that certain animals are able to smell in stereo, as well. One of those mammals, the common mole (Scalopus aquaticus), frequently found...

Insects Spend A Lot Of Time Grooming
2013-02-05 04:30:20

April Flowers for redOrbit.com - Your Universe Online A new study, led by North Carolina State University, shows like self-absorbed teenagers, insects spend a lot of time grooming. This grooming, specifically antennal cleaning, is a common function of insects that removes both environmental pollutants and chemicals produced by the insects themselves. Grooming helps insects maintain acute olfactory senses, the study shows, which are responsible for a host of functions such as food...

Quantum Smell May Exist
2013-01-28 19:48:08

Brett Smith for redOrbit.com — Your Universe Online The majority of the scientific community has embraced the idea of different smells being based on the olfactory receptors´ ability to detect various shapes of odor molecules. However, a new study in the open access journal PLOS ONE has given credence to a less popular theory; that the sense of smell is based on the molecules´ different vibrations, not their shapes. The idea of a quantum, or vibration, basis for...

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...
