Mosquitoes Detect Human Scents Better During The Nighttime
2013-08-31 07:21:08

redOrbit Staff & Wire Reports – Your Universe Online In research that could change the way we protect ourselves from mosquitoes, scientists from the University of Notre Dame's Eck Institute for Global Health have discovered the disease-carrying insects are able to smell major human host odorants better during the nighttime hours. The study, which appears in this week’s edition of the open-access journal Nature: Scientific Reports, used an integrative approach to investigate the...

Single Olfactory Gene Helps Mice Detect Predators
2013-04-30 08:47:01

Alan McStravick for redOrbit.com — Your Universe Online Dogs can hear sounds at higher frequencies. Bats can ℠see´ with sonar although their eyes are practically useless. And, apparently, the mouse can smell a predator´s urine from a mile away. Each of these traits has played an important role in the evolution of each animal. But what is especially amazing with regard to mice and their olfactory receptors is their ability to sense a threat may be determined by only...

Bohemia, NY (PRWEB) April 09, 2013 On April 9, Yumi Media, a food website devoted to delivering the latest and greatest in food news, recipes, and products to incorporate into your own healthy lifestyle, responds to an article published on Discovery News by Jennifer Viegas, which goes over how certain internal organs may be able to...

Your Nose Isn’t The Only Organ That Can Smell
2013-04-08 12:47:35

Brett Smith for redOrbit.com - Your Universe Online The nose is a highly specialized organ, and for years it has been assumed that it is the only part of the human body which is finely attuned to receiving and process odors. However, a new study presented at 245th National Meeting & Exposition of the American Chemical Society in New Orleans reported that heart, blood, lung and other cells have the same receptors for sensing odors that are present in the nose. "Our team recently...

Insect odorant receptors regulate their own sensitivity. Highly developed antennae containing different types of olfactory receptors allow insects to use minute amounts of odors for orientation towards resources like food, oviposition sites or mates. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now used mutant flies and for the first time provided experimental proof that the extremely sensitive olfactory system of fruit flies – they are able to...

Quantum Smell May Exist
2013-01-28 19:48:08

Brett Smith for redOrbit.com — Your Universe Online The majority of the scientific community has embraced the idea of different smells being based on the olfactory receptors´ ability to detect various shapes of odor molecules. However, a new study in the open access journal PLOS ONE has given credence to a less popular theory; that the sense of smell is based on the molecules´ different vibrations, not their shapes. The idea of a quantum, or vibration, basis for...

Odor And The Brain: What The Nose Knows
2012-11-15 11:36:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Specific patterns in the nasal passageway that determine which olfactory neurons are associated with which particular odors have remained a mystery for scientists. The human nose has millions of these olfactory neurons grouped into hundreds of different neuron types. And each of these neuron types expresses only one odorant receptor in one region of the brain, allowing that specific odor to be sensed. Now, researchers from UC...

A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules. The study, in the journal Physical Chemistry Chemical Physics, demonstrates the feasibility of the theory — first proposed decades ago — that the vibration of an odorant molecule´s chemical bonds — the wagging, stretching and rocking of the links between atoms — contributes to...

John Neumann for redOrbit.com — Your Universe Online Researchers have long known that ants live in some of the most complex social structures of any animal. With the division of labor and communication between individual ants and the ability to solve complex problems, the reason for such complex structures may be the increased number of smells that ants can discern. A team of scientists, led by Lawrence Zwiebel and his research team at Vanderbilt, recently completed the first full...

Genes May Explain Why Some People Don't Like  Meat
2012-05-03 06:12:52

If you don't like the taste of pork, the reason may be that your genes cause you to smell the meat more intensely, according to a new study. Duke University Medical Center scientists, working with colleagues in Norway, found that about 70 percent of people have two functional copies of a gene linked to an odor receptor that detects a compound in male mammals called androstenone, which is common in pork. People with one or no functional copies of the gene can tolerate the scent of...
