Michael Harper for RedOrbit.com More news was made this week in the ongoing struggle between the classes. No, not the wealth classes or the classes of status: The classes of age. We´ve all been a part of this struggle and have seen it played out first hand. The younger class – say, ages 20 and up – are just ready to, like, live their life, you know? They can´t be bothered when “the man” tries to bring them down. Then there´s the class of the...

(Ivanhoe Newswire) -- Does your grandma really have that "grandma scent" that you think that she does? New research says yes! The study conducted by Monell Center shows that humans can identify the age of other humans based on differences in body odor. "Similar to other animals, humans can extract signals from body odors that allow us to identify biological age, avoid sick individuals, pick a suitable partner, and distinguish kin from non-kin," senior author Johan Lundstrom, a sensory...

Research from Karolinska Institutet shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals. "I've never...

Almost a century after telephone pioneer Alexander Graham Bell first popularized the idea of measuring smells, chemical vapor sensors “• "electronic noses" “• are being developed for use in diagnosing disease, detecting national security threats, and other futuristic uses. A new episode in the American Chemical Society's (ACS) award-winning Bytesize Science series takes viewers on a behind-the-science tour of a major lab that is developing affordable, easy-to-carry...

Newly developed analytic device 'Flywalk' allows accurate studies of insect behavior to be made In collaboration with colleagues from Portugal and Spain, researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, have developed an apparatus that automatically applies odors to an airstream, while filming and analyzing the behavior of insects simultaneously. The system is called Flywalk and consists of glass tubes, airstream regulators, and a video camera. The reactions...

Study identifies mechanism to explain how the body responds to potentially threatening negative odors Anxious people have a heightened sense of smell when it comes to sniffing out a threat, according to a new study by Elizabeth Krusemark and Wen Li from the University of Wisconsin-Madison in the US. Their work´ is published online in Springer's journal Chemosensory Perception. The study is part of a special issue² of this journal on neuroimaging the chemical senses. In...

People born without a sense of smell experience higher social insecurity and increased risk for depression, according to a study published Mar. 21 in the open access journal PLoS ONE. The authors of the study, led by Ilona Croy of the University of Dresden Medical School in Germany, investigated 32 individuals born without a sense of smell, known as isolated congenital anosmia. They found that the non-smellers did not have significant deviations from the norm in terms of many daily...

Brain Handles Odors In A Different Way
2012-03-22 05:44:48

Researchers from the Stowers institute for Medical Research have traced individual odor molecules in the brain to create a new model of how our sense of smell works. While once thought to cluster related smells, researchers have know discovered that the brain reacts to smells in a broader sense. Previous research has shown that the brain handles the senses in a very orderly way. Things that we touch were thought to be mapped together in the somatosensory cortex, things that we heard...

How are 100 billion cells created, each with specific duties? The human brain is evidence that nature can achieve this. Researchers at Linköping University in Sweden have now taken a step closer to solving this mystery. "Knowledge about the mechanisms that diversify neurons and keep them diverse is necessary in order to cultivate and replace nerve cells in the future," says Mattias Alenius, Assistant Professor of Neuroscience, who has published his research breakthrough...

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...
