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...

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.

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...

Understanding The Nose
2012-12-19 18:59:17

Michael Harper for redOrbit.com — Your Universe Online Science is a magnificent thing and yet, there is still so much we don´t yet understand. For instance, scientists are still working to fully understand the part of our body that resides right in front of our face. More than 100 years ago, scientists discovered a mechanism that provides feedback from our nose to our brain. Though these scientists discovered this mechanism, they weren´t yet able to fully understand how it...

To Prepare Defenses Against Pesky Insect Plant Will Sniff Out Danger
2012-12-17 17:44:21

Penn State A plant may start to prime its defenses as soon as it gets a whiff of a male fly searching for a mate, according to Penn State entomologists. Once tall goldenrod plants smell a sex attractant emitted by true fruit fly males, they appear to prepare chemical defenses that make them less appealing to female flies that could damage the plants by depositing eggs on them, the researchers said. "It's become increasingly clear in recent years that plants are responsive to odors,"...

Hawk Moths Learn To Use Brain To Find Alternative Food Sources
2012-12-07 13:38:08

Brett Smith for redOrbit.com - Your Universe Online When their favorite food isn´t readily available, hawk moths are able to switch to a different olfactory ℠channel´ in their brain, enabling them to learn how to find alternative nectar sources, according to a new report in the journal Science Express. The two olfactory channels allow the moths to survive in a changing floral environment and the researchers are expecting that better understanding of this mechanism...

How Flies Avoid Rotten Food
2012-12-07 07:23:29

[ Watch the Video: Flies Sniff Out and Avoid Spoiled Food ] April Flowers for redOrbit.com - Your Universe Online Eating spoiled food can be fatal as it allows bacterial pathogens to enter the digestive system. One of the main tasks of the sense of smell is to detect signs of decay, allowing us and other animals to avoid such food poisoning. A new study, conducted by behavioral scientists and neurobiologists at the Max Planck Institute for Chemical Ecology, has decoded the neural...

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...
