We all know certain smells can bring memories back to life. A christmas tree, your grandma’s baking scents or your first brand of deodorant can take your mind straight back to other times. But these smells can also help us to predict the future, science shows. Marijn van Wingerden has found the part of the brain that makes this possible.
According to the news site RocketNews24, the Japanese company Chaku Perfume has "developed a new communication service in the way of an iPhone application and device called “Chat Perf,” which can send smells across cyber space. Amazing!"
This post will describe the smelly, somewhat weird, yet informative study that proves that your odor might just give away your age.
A good sense of smell may have contributed to the development of certain kinds of social functions in Homo sapiens, according to a new study. Scientists used 3D modeling to reconstruct modern human and Neanderthal brains and discovered that the olfactory areas, which govern smell, are larger in humans. Their models also show that humans have larger temporal lobes, regions related to social behavior. Future studies will explore the possibility of a connection between the olfactory and temporal regions of the brain and the evolution of sophisticated social behavior in humans.

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.
Bite size depends on the familiarly and texture of food. Smaller bite sizes are taken for foods which need more chewing and smaller bite sizes are often linked to a sensation of feeling fuller sooner.
When one fish gets injured, the rest of the school takes off in fear, tipped off by a mysterious substance known as "Schreckstoff" (meaning "scary stuff" in German). Now, researchers have figured out what that scary stuff is really made of.
Do you get a headache from the perfume of the lady next to you at the table? Do cleaning solutions at work make your nose itch?
Meet Olly, the web-connected, smelly robot. He, and it is a “he,” takes your @mentions, status updates and more and turns them into the smell of your choice. Created by a London-based designer, Olly is still a Kickstarter project with a $35,00 goal. Articles about robotics: http://www.scoop.it/t/science-news?tag=robotics
High-tech medical imaging techniques were recently used to access internal structures of fossil human skulls.
From pheromones to disease detection via smell, or what your nose has to do with the neurochemistry of nostalgia.
(Medical Xpress) -- An interesting study conducted by Polish researchers Agnieszka Sorokowska, Piotr Sorokowski and Andrzej Szmajke, of the University of Wroclaw, has found that people are able to guess a person’s type of personality to a...

Humans can smell fear and disgust, and the emotions are contagious, according to a new study. The findings, published Nov. 5 in the journal Psychological Science, suggest that humans communicate via smell just like other animals.
Scientists in the US have developed a novel system for detecting landmines by training rats equipped with GPS and wireless rucksacks to sniff out explosives and map them for destruction.

Researchers may have solved a piece of the puzzle surrounding how fish “smell” harm. When one fish is injured, others nearby may dart, freeze, huddle, swim to the bottom or leap from the water. The other fish know that their school mate has been harmed. But how?
“Smell is very primitive, but at the same time has direct links to the highest centers of the brain,” says Donald Wilson, professor of child and adolescent psychiatry at New York University. Odor receptors in the nose are actually extensions of the olfactory bulb in the brain, which “has fingers on buttons affecting what we eat, with whom we mate, what we’re afraid of.” Articles about NEUROSCIENCE: http://www.scoop.it/t/science-news?page=1&tag=neuroscience
People born without a sense of smell experience higher social insecurity and increased risk for depression.
Just like a road atlas faithfully maps real-word locations, our brain maps many aspects of our physical world: Sensory inputs from our fingers are mapped next to each other in the somatosensory cortex; the auditory system is organized by sound frequency; and the various tastes are signaled in different parts of the gustatory cortex.
A new study from Nature, claims that the brain pathway for sexual behavior in male mice are also present in the female mice. That suggests that their is potential for a female mouse to exhibit sexual male behavior. What makes it even more interesting is that these behaviors can be triggered by different smells. Like many other animals, mice uses pheromones to signal sexual behaviors, but what happens when you disables the part of the nose that receive these signals?
“The smell of a body is the (bacteria themselves) which we breathe in with our nose and mouth, which we suddenly possess as though (they) were (the body’s) most secret substance and, to put the matter in a nutshell, its nature. The smell which is in me is the fusion of the (bacteria) with my body…”
Did you know? Dogs, sense of smell is about one hundred thousand to one million times stronger than a human's.
While the human brain is dominated by a large visual cortex, the dog brain is dominated by an olfactory cortex.

Sexually transmitted diseases may make people smell less pleasant to the opposite sex. In the study, men with gonorrhea were rated as having a sweat that smelled less pleasant than the sweat of men without gonorrhea.
