Crafting a fragrance for detergents that leaves laundry smelling clean and fresh. Developing a room freshener, scented oil, or scented candle that whispers "cool spring air." Giving toothpaste or mouthwash a refreshing aftertaste that lingers and lingers. The process for putting the smell that sells into thousands of consumer products is much like composing a symphony, according to maestro fragrance designer Michael Papas, who spoke at the 240th National Meeting of the American Chemical...

Whether a fish likes to hunt down its food or wait for dinner to arrive is linked to the composition of its brain, a University of Guelph researcher has revealed. Prof. Rob McLaughlin has discovered that foraging behaviour of brook trout is related to the size of a particular region in the fish's brain. "We found that the fish that swim around in the open in search of food have larger telencephalons than the fish that sit along the shoreline and wait for food to swim by in the water column,"...

New research, published in the journal Development, by Dr. Anthony-Samuel LaMantia, professor of Pharmacology & Physiology and director of the newly formed GW Institute for Neuroscience, and his colleagues have identified the stem cells that generate three critical classes of nerve cells "“ olfactory receptors (ORNs), vomeronasal (VRNs) and gonadotropin releasing hormone (GnRH) neurons "“ that are responsible for enabling animals and humans, to eat, interact socially and...

It's no secret that sharks have a keen sense of smell and a remarkable ability to follow their noses through the ocean, right to their next meal. Now, researchers reporting online in the June 10th issue of Current Biology, a Cell Press publication, have figured out how the sharks manage to keep themselves on course. It turns out that sharks can detect small delays, no more than half a second long, in the time that odors reach one nostril versus the other, the researchers report. When the...

Impaired ability to detect odors and irritants 2 years after buildings' collapse New research from the Monell Center and collaborating institutions reports that workers exposed to the complex mixture of toxic airborne chemicals following the 9/11 disaster had a decreased ability to detect odors and irritants two years after the exposure. "The nose performs many sensory functions that are critical for human health and safety," said lead author Pamela Dalton, PhD, MPH, an environmental...

The findings provide clues to how our brains work Scientists from The Scripps Research Institute have found a specific chemical compound secreted by many predators that makes mice behave fearfully. The research helps scientists better understand animal behavior, and may eventually lead to new insights into how sensory information is processed in human brains. The research was published in the prestigious journal Cell on May 14, 2010. "We're interested in how the brain can be hardwired to...

WASHINGTON, May 13 /PRNewswire/ -- The Campaign for Safe Cosmetics (CSC) published a report on May 12, 2010 entitled "Not So Sexy - The Health Risks of Secret Chemicals in Fragrance" which includes alarmist phrases such as: "can trigger allergic reactions," "disrupt hormones," "end up inside people's bodies." The Fragrance Materials Association of the United States (FMA) says the reality is that fragrances are safe. The industry has a long and comprehensive safety testing program for its...

Males generate new brain cells and form memories leading to positive relationships New research from neuroscientist Samuel Weiss, PhD, director of the Hotchkiss Brain Institute at the Faculty of Medicine, shows that paternal mice that physically interact with their babies grow new brain cells and form lasting memories of their babies. The study is published on-line this week in the prestigious international journal, Nature Neuroscience. Weiss and his team find that when paternal mice interact...

Researchers in the Department of Entomology,  University of California, Davis, have discovered that the fruit fly has a native odorant receptor that detects the silkworm moth's sex pheromone, and that it's "amazingly more sensitive" than the moth's odorant receptor. Their work could open research doors for insect-inspired biosensors. The odor detector or OR is a means of chemical communication that helps insects find mates.  The olfactory link between silkworm moths (Bombyx mori)...

Heidelberg neuroscientists verify for the first time the function of inhibiting communication / Published in "Neuron" Whether different odors can be quickly distinguished depends on certain synapses in the brain that inhibit nerve stimulation. The researchers in Professor Dr. Thomas Kuner's team at the Institute of Anatomy and Cell Biology at Heidelberg University Medical School and Dr. Andreas Schäfer at the Max Planck Institute for Medical Research have shown that mice in which a...

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...
