That's because their new study, being reported at the American Association for Cancer Research (AACR) Annual Meeting 2012, shows that using estrogen and a c-Src inhibitor, PP2, cancel each other out.

The BioRepair toothpaste survey found almost four out of 10 adults rated white teeth and a healthy smile as the most important physical attribute. It also revealed that one in four said physique was the first thing that attracted them when they met someone of the opposite sex, and only 11.8 percent thought eyes were most important....]]> http://www.medindia.net/news/Sexual-Attraction-Tip-101-Smile-90762-1.htm http://www.medindia.net/news/Your-Hunger-Hormone-Increases-Your-Ability-to-Sniff-Out-Food-83640-1.htm A hormone, known to promote hunger, has been found to enhance exploratory sniffing in both animals and humans, according to a new study. The findings suggest ghrelin may enhance the ability to find and identify food. Researchers, led by Jenny Tong and Matthias Tschop at the University of Cincinnati, found the appetite-related hormone also influences smell. The new study shows ghrelin, made mainly in the stomach, binds to molecules in the brain's olfactory bulb, suggesting the hormone is directly involved in odour processing....]]> http://www.medindia.net/news/Your-Hunger-Hormone-Increases-Your-Ability-to-Sniff-Out-Food-83640-1.htm http://www.medindia.net/news/Bed-Bugs-Cannot-Stand-the-Smell-of-Pheromones-83095-1.htm Researchers from Lund University and Mid Sweden University have discovered a unique kind of smell produced by bed bugs, and have called it as "alarm pheromones". Researchers further discovered that the bed bugs which are not fully developed, called as nymph bed bugs, give out a smell which other bedbugs- both adult and nymph find intolerable. Researchers are holding on to this discovery in the hope that these repulsive "alarm pheromones" might help in controlling bedbugs.

According to experts at the Oregon Environmental Council, some of those chemicals could have a wide-range of health effects. An example is Portland resident Ashley Henry, who developed asthma last spring, and became hypersensitive to fragrances and other chemicals in her home.

Well, the reason would be your taste in music. In a recent study it has been highlighted that music actually predicts sexual attraction. The most recent issue of Psychology of Music exmaines the link between identity, music and what makes people 'click'. This had led the LA Weekly blog to explore what it is about why we like, what we like, and perhaps more importantly, how this can make or break a relationship.

This, even though, they are notorious for creating some of the most repugnant smells on earth, scientists reveal. The study by a team of marine microbiologists at Newcastle University has shown how bacteria are capable of 'olfaction' - sensing volatile chemicals in the air such as ammonia produced by rival bacteria present in the environment.

These are the findings of a new study believed to be the first that paired indoor and outdoor air samples for such wide range (104) of these substances. The study appears in ACS' IEnvironmental Science (and) Technology/I, a semi-monthly journal.

Researchers at the University of Maryland School of Medicine in Baltimore knew how mice pair a particular odour with a chemical ingredient found in mouse breath. And now they know how mice manage to sniff that connection out.

The findings are important because BPA is thought to impact human development and is classified as an endocrine disrupting chemical, potentially putting developing infants at risk, as well as fetuses if pregnant mothers are exposed.

Neil is a somewhat excitable, dark-haired 18-month-old German Shepherd dog but it has a healthy wet nose which crucially for the people of Iraq has been trained to sniff out explosives. During a demonstration at a checkpoint in Baghdad, Neil scurried around a car, smelling its front and back seats, boot and bonnet, before a handler patted its head approvingly and told a temporarily inconvenienced driver he could go....]]> http://www.medindia.net/news/Amid-Iraq-Bomb-Threats-Dogs-Sniff-Out-Explosives-65542-1.htm http://www.medindia.net/news/Response-to-Pheromones-and-Odors-in-Mouse-Sensory-Neurons-Increased-by-Chlorides-62947-1.htm Research has revealed that the vomeronasal organ (VNO) is an odor detection system that mediates many pheromone-sensitive behaviors. Vomeronasal sensory neurons (VSNs), located in the VNO, are the initial site of interaction with odors and pheromones. How an individual VSN transduces chemical signals into electrical signals, however, has been a mystery. In the January 2010 issue of the IJournal of General Physiology/I, researchers from the University of Vermont show that a Ca 2+ -activated ...]]> http://www.medindia.net/news/Response-to-Pheromones-and-Odors-in-Mouse-Sensory-Neurons-Increased-by-Chlorides-62947-1.htm http://www.medindia.net/news/New-Diagnostic-Tool-Pets-to-Sniff-Out-Owners-Cancer-62798-1.htm Our pets have an inherent ability to detect cancers was proved when a dog in Oz sniffed out its owner's cancer and ultimately saved her life, has lent further support to the belief.

The study, published in Nature, also identified the neurons in the fly's antenna that detect this pheromone and relay the information to the brain to elicit aggression. According to biologists from the California Institute of Technology (Caltech), the findings could help unravel the mystery of how aggression is hardwired into the brain by an animal's genes.

The device depends upon recognising a pheromone - or scent signal - produced in sweat of a scared person. The researchers hope that the novel equipment would make it possible to identify individuals at checkpoints who are up to no good. Terrorists with murder in mind, drug smugglers, or criminals on the run are likely to be very fearful of being discovered.

Now, Israel's Tel Aviv University (TAU) researchers have developed a device which can be used to detect even microscopic signs of cancer, bombs and impure water. The instrument has been dubbed a 'bionic nose'. Both cancer cells and the chemicals used to make bombs can foil detection because they appear in trace amounts too small for conventional detection techniques.

In today's advertising world, marketers are increasingly using radical images that include nudity and sexual language.

The finding is based on a study led by Wen Li, a post-doctoral fellow in the Cognitive Neurology and Alzheimer's Disease Centre at Northwestern's Feinberg School of Medicine, which stated that minute amounts of odours elicited salient psychological and physiological changes, which suggests that humans get more information from barely perceptible scents.
