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...

Researchers Create White Odor Based On Concept Behind White Noise
2012-11-22 11:01:50

Lawrence LeBlond for redOrbit.com - Your Universe Online When it comes to white, we use our senses in different ways to make astute judgments of what we are seeing, touching and perhaps hearing. Now, researchers from the Weizmann Institute of Science in Israel are showing us what white smells like. The color white is a blend of many different wavelengths of light. When you mix a few colors you get a brand new color, and with a mix of several colors, eventually white is created. Other...

Dogs Inspire New Electronic Nose
2012-11-20 14:42:58

Michael Harper for redOrbit.com — Your Universe Online [ Watch the Video: Nanotech Device Mimics Dog´s Nose to Detect Explosives ] A dog´s nose is 1,000 times better at picking up scents than a human´s nose. Dogs have long been used to sniff out drugs and explosives at the nation´s borders and airports. As such, it only makes sense to model an electronic nose after the canine´s. The University of California at Santa Barbara (UCSB) has managed to do just...

Odor And The Brain: What The Nose Knows
2012-11-15 11:36:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Specific patterns in the nasal passageway that determine which olfactory neurons are associated with which particular odors have remained a mystery for scientists. The human nose has millions of these olfactory neurons grouped into hundreds of different neuron types. And each of these neuron types expresses only one odorant receptor in one region of the brain, allowing that specific odor to be sensed. Now, researchers from UC...

Smell Like A Rose For Hours With New Perfume Candy
2012-11-12 09:41:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Do you ever watch advertisements for new products and ask: ℠What will they think of next?´ Well that might be the question you´d ask yourself after reading about this next product--which promises to keep you ℠smelling sweet´ for hours. BENEO, an Belgium-based manufacturer, has created a sweet candy that not only tastes great, but also keeps the imbiber smelling sweet for up to six hours, by releasing a...

Emotional Communication Uses Sense Of Smell
2012-11-06 12:58:08

April Flowers for redOrbit.com - Your Universe Online While is it well known that many species transmit information via chemical signals, the extent to which these chemosignals play a role in human communication is unknown. Researchers from Utrecht University in the Netherlands have investigated whether we humans might actually be able to communicate with each other about our emotional states through chemical signals. The findings of the study were recently published in the journal...

Lab Rats Can Fine-tune Their Sense Of Smell
2012-10-31 11:23:10

Brett Smith for redOrbit.com - Your Universe Online A new study by University of Chicago researchers showed that some animals are able to focus their sense of smell in much the same way that humans can focus their vision. According to the study that was published in the current issue of the Journal of Neuroscience, the researchers found that laboratory rats were able to adjust their sense of smell by altering their sniffing, which brought scents to receptors in different parts of their...

Newborn Mice Rely On Mother's Odor For Breastfeeding
2012-10-05 13:52:58

[Watch Video: Newborn Mice Depend On Mom's Signature Scent] April Flowers for redOrbit.com - Your Universe Online Sometimes, not finding what you are looking for can lead to even more interesting avenues of research. That is what a recent international research team found out when they were searching for a pheromone trigger for newborn infant suckling responses in mice. The results of their study have been published in the journal, Current Biology. Long-held wisdom has been that...

A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules. The study, in the journal Physical Chemistry Chemical Physics, demonstrates the feasibility of the theory — first proposed decades ago — that the vibration of an odorant molecule´s chemical bonds — the wagging, stretching and rocking of the links between atoms — contributes to...

John Neumann for redOrbit.com — Your Universe Online Researchers have long known that ants live in some of the most complex social structures of any animal. With the division of labor and communication between individual ants and the ability to solve complex problems, the reason for such complex structures may be the increased number of smells that ants can discern. A team of scientists, led by Lawrence Zwiebel and his research team at Vanderbilt, recently completed the first full...
