NYU Researchers id new class of photoreceptors,pointing to new ways sights-and smells-are regulated
The identification of a new class of photoreceptors in the retina of fruit flies sheds light on the regulation of the pigments of the eye that confer color vision, researchers at New York University's Center for Developmental Genetics report in a new study appearing in the Public Library of Science's journal, PloS Biology.   view more (2008-04-22)

Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn.   view more (2008-04-14)

Sniffing out danger
Each human nose encounters hundreds of thousands of scents in its daily travels perched front and center on our face. Some of these smells are nearly identical, so how do we learn to tell the critical ones apart?   view more (2008-03-28)

Growth hormone found to have new role in development of brain's smell center
A human hormone known to stimulate the growth of cells throughout the body has a new role - helping to set up the proper nerve connections in the odor center of the brain, according to University of California, Berkeley, scientists.   view more (2008-03-27)

Two 'noses' are necessary for flies to navigate well
Animals and insects communicate through an invisible world of scents. By exploiting infrared technology, researchers at Rockefeller University just made that world visible.   view more (2007-12-27)

Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement.   view more (2007-12-06)

Pheromones Identified that Trigger Aggression between Male Mice
A family of proteins commonly found in mouse urine is able to trigger fighting between male mice, a study in the Dec. 6, 2007, issue of Nature has found.   view more (2007-12-06)

Wake up and smell the sweat
Some people are oblivious to the odor in the locker room after a game, while others wrinkle their noses at the slightest whiff of sweat.   view more (2007-11-26)

New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine... view more...

Odd protein interaction guides development of olfactory system
Scientists have discovered a strange mechanism for the development of the fruit fly antennal lobe, an intricate structure that converts the chaotic stew of odors in the environment into discrete signals in the brain.    view more (2007-10-30)

Study identifies pathway required for normal reproductive development
Massachusetts General Hospital (MGH) clinical researchers, in collaboration with basic scientists from the University of California, Irvine (UC Irvine) have identified a new molecular pathway required for normal development of the reproductive, olfactory and circadian systems in both humans and mice.   view more (2007-10-16)

Mice use specialized neurons to detect carbon dioxide in the air
For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby.   view more (2007-08-17)

Disabling a sensory organ prompts female mice to act like male mice
By short-circuiting the sensory organ that detects the chemical cues mice use to attract mates, a team of Howard Hughes Medical Institute (HHMI) researchers has prompted female mice to behave like male mice in the throes of courtship.   view more (2007-08-06)

Research study describes the role part of the brain plays in memory
A research with experimental rats carried out by the Institute of Neuroscience of the UAB describes the brain region connected to how our declarative memory functions.   view more (2007-07-18)

Insight into neural stem cells has implications for designing therapies
Scientists have discovered that adult neural stem cells, which exist in the brain throughout life, are not a single, homogeneous group.   view more (2007-07-09)

Physicist cracks women's random but always lucky choice of X chromosome
A University of Warwick physicist has uncovered how female cells are able to choose randomly between their two X chromosomes and why that choice is always lucky.   view more (2007-06-13)

New research shows sharks use their noses and bodies to locate smells
Sharks are known to have a keen sense of smell, which in many species is critical for finding food. However, according to new research from Boston University marine biologists, sharks can not use just their noses to locate prey; they also need their skin - specifically a location called the lateral line.   view more (2007-05-30)

Studies assess effectiveness of serotonin and nerve stimulants on irritable bowel syndromes
Studies have shown that gastrointestinal (GI) tract function is often influenced by specific stimulants or reactors, which sometimes cause irritable bowel syndrome (IBS) or constipation.   view more (2007-05-22)

Left-right wiring determined by neural communication in the embryonic worm
Most animals appear symmetrical at first glance, but we're full of internal lop-sidedness. From the hand used to pick up a pencil or throw a baseball, to where language is generated in the brain, to the orientation of our internal organs, humans are a glut of asymmetries.   view more (2007-05-18)

Biosensor sniffs out explosives
Temple University School of Medicine researchers have developed a new biosensor that sniffs out explosives and could one day be used to detect landmines and deadly agents, such as sarin gas, according to a paper in the June issue of Nature Chemical Biology.   view more (2007-05-09)
