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.

This talented plant is commonly known as the dodder vine. It's a parasite; tomato gardeners know it and hate it. Here it is at Penn State University — look for the stringy, wiggly thing on the left — sniffing. Notice as it grows from a seedling, it moves in small, lazy circles, like hands groping in the dark, and then, gradually, it leans toward the stalk of the tomato plant — which it then entwines, gouges, sucks and strangles.

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.

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.

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

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.
