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...

When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then up and down until you find the metal or plastic plate of the switch. During the process you use your sense of touch to develop an image in your mind of the wall´s surface and make a better guess for where the switch is. Sliman Bensmaia, PhD, assistant professor of organismal biology...

Mechanisms Behind Response To Gentle Touch Discovered
2012-12-10 05:47:22

redOrbit Staff & Wire Reports - Your Universe Online A team of University of California, San Francisco (UCSF) researchers has reportedly discovered the group of nerve cells responsible for communicating the sensation of gentle touch in fruit flies -- and possibly in humans and other organisms as well -- potentially shedding light on one of most mysterious senses in all of biology. In their research, which has been published online by the journal Nature, the UCSF researchers studied...

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...

Crocodiles And Alligators Are Actually Sensitive Creatures
2012-11-08 14:12:17

Brett Smith for redOrbit.com - Your Universe Online Crocodiles and alligators are well-known for being cold-blooded and having thick skin, but new research from a pair of Vanderbilt University scientists has shown that the ancient reptiles can be quite sensitive. More specifically, the scientists demonstrated that these reptilian predators have small pigmented domes that dot their skin-- conveying a sense of touch is even more responsive than that of humans, according to the pair´s...

Researchers Train Humans To Sense Like Rats
2012-11-06 12:01:01

April Flowers for redOrbit.com - Your Universe Online By moving their facial whiskers back and forth about eight times a second to locate objects in their environment, rats use a sense that humans don´t: whisking. Researchers from the Weizmann Institute of Science in Rehovot, Israel, however, have set out to learn whether humans could acquire this sense with practice, and if so, what could understanding the process of adaptation tell us about our normal senses? To investigate this...

Brain Can Compensate For Minimal Visual Input
2012-11-02 08:57:31

Alan McStravick for redOrbit.com - Your Universe Online Consciousness and perception have long been understood as being interlinked. But our perceptions may be related less to our sense of sight than was previously understood. A new study by researchers at the University of Virginia shows that vision may be less important to our ability to see than is the brain´s ability to process the individual points of light we encounter into more complex images. Their study of the fruit...
