According to Slashdot and some awesome guy named Big Alan (AKA Alan Hirsch):

… the key to a man’s heart, and other parts, is pumpkin pie. Out of the 40 odors tested in Hirsch’s study, a mixture of lavender and pumpkin pie got the biggest rise out of men ages 18 to 64. That particular fragrance was found to increase penile blood flow by an average of 40%. “Maybe the odors acted to reduce anxiety. By reducing anxiety, it acted to remove inhibitions,” said Hirsch.

When people are anxious they release a chemical signal that’s detectable on a subconscious level by those close to them. That’s the implication of a new study that collected sweat from people as they completed a high-rope obstacle course, and then tested the effect of that sweat on study participants as they played a gambling game.

Katrin Haegler’s team placed the sweat samples inside odourless tea bags which were attached with an elastic band to the underside of the gambling participants’ noses. For comparison, the participants were also exposed to sweat collected from non-anxious riders of an exercise bike.

When exposed to the anxious sweat, the participants took longer to decide over, but were more likely to bet on the highest risk scenarios. (…) In other words, the detection of another person’s anxiety made them more willing to take risks. Quite why this should be remains unclear.

Zak gave 4 millilitres of oxytocin or a placebo saline solution to 40 male volunteers in the form of a nasal spray. The volunteers were then shown 16 commercials seeking to curtail smoking, drinking, speeding, and global warming. (…)

Significantly more people who had been given oxytocin donated money than those given saline. They also donated on average 57 per cent more money. The results were presented this week at the Society for Neuroscience annual meeting in San Diego.

Oxytocin is well-known for its role in empathy and trust, though is currently only available on prescription. As a result, at the moment it can’t be used by advertisers to persuade us to feel more favourable towards their product, though many make sure their adverts contain images that evoke bursts of natural oxytocin, such as children and pets, says Zak.

New Yorkers are accustomed to strong odors, but several years ago a new aroma began wafting through the city’s streets, a smell that was more unnerving than the usual offenders (trash, sweat, urine) precisely because it was so delightful: the sweet, unmistakable scent of maple syrup. It was a fickle miasma, though, draping itself over Morningside Heights one afternoon, disappearing for weeks, reemerging in Chelsea for a few passing hours before vanishing again. Fearing a chemical warfare attack, hundreds of New Yorkers reported the smell to authorities. (…) The city quickly determined that the odor was harmless, but the mystery of its origin persisted for four years.

During maple syrup events, as they came to be called, operators at the city’s popular NYC311 call center—set up to field complaints and provide information on school closings and the like—were instructed to reassure callers that they could go about their business as usual.

But then city officials had an idea. Those calls into the 311 line, they realized, weren’t simply queries from an edgy populace. They were clues.

On January 29, 2009, another maple syrup event commenced in northern Manhattan. The first reports triggered a new protocol that routed all complaints to the Office of Emergency Management and Department of Environmental Protection, which took precise location data from each syrup smeller. Within hours, inspectors were taking air quality samples in the affected regions. The reports were tagged by location and mapped against previous complaints. A working group gathered atmospheric data from past syrup events: temperature, humidity, wind direction, velocity.

Seen all together, the data formed a giant arrow aiming at a group of industrial plants in northeastern New Jersey. A quick bit of shoe-leather detective work led the authorities to a flavor compound manufacturer named Frutarom, which had been processing fenugreek seeds on January 29. Fenugreek is a versatile spice used in many cuisines around the world, but in American supermarkets, it’s most commonly found in the products on one shelf—the one where they sell cheap maple-syrup substitutes.

Fifteen months after the Maple Syrup Mystery was solved, mayor Michael Bloomberg paid a visit to the 311 call center. (…) Launched in March 2003, 311 now fields on average more than 50,000 calls a day, offering information about more than 3,600 topics: school closings, recycling rules, homeless shelters, park events, pothole repairs. The service has translators on call to handle some 180 different languages.

Body odors are important cues used for social and sexual discrimination. As was shown many times, animals can easily smell age-, health- and genetics-related  differences.  Recent study of our large-eyed relatives, ring-tailed lemurs, demonstrate that drugs can alter body scents and change behavior.

Researchers examined changes in endocrine and  semiochemical profiles of sexually mature female lemurs treated with hormonal contraceptives during their breeding season. (…) The conclusion? Contraceptives change chemical ‘signature’, minimizing distinctiveness and genetic fitness cues. No more can the males determine which females are genetically and physically beautiful. All contracepted females lost their individuality and started to smell funny.

Can a clean smell make you a better person?

That’s the provocative suggestion of a recent study in the journal Psychological Science. A team of researchers found that when people were in a room recently spritzed with a citrus-scented cleanser, they behaved more fairly when playing a classic trust game. In another experiment, the smell of cleanser made subjects more likely to volunteer for a charity.

The findings suggest that simply smelling something clean makes people clean up their behavior - that a smell can provoke a mental leap between cleanliness and morality, making people think differently about the world around them. The authors even suggested that clean smells could be employed as a tool to influence how people act.

The idea that a smell can affect something as complex as ethical behavior seems surprising, not least because smell has long been seen as a “lower” sense, playing on our emotions and instincts while our reason and judgment operate on another plane. But research increasingly shows that smell doesn’t just affect how we feel: It affects how we think, in ways that are just beginning to be understood.

One of the works that helps visualize the breakthrough is a painting done in 1961, which consists in a greatly enlarged version of a simple black-and-white advertisement of the kind that appears in side columns and back pages of cheap newspapers. It advertised the services of a plastic surgeon, and showed two profiles of the same woman, before and after an operation on her nose.
