Can Dogs Help Locate Rare Plants?
Dogs use their remarkable sense of smell to uncover illegal drugs and locate missing persons. So why not threatened plants and animals, too? In Oregon, the Conservancy is using detector dogs like Rogue to find Kincaid's lupine and help save an endangered butterfly found nowhere else on Earth.

Mature brains need a continuous supply of new nerve cells to sustain functions like smelling and memory, an experiment with mice in Japan has shown.

While the adult brain can make new nerve cells, experts have never been sure of their roles. These findings may explain why some stroke survivors never recover certain faculties, because their brains no longer generate new cells.

Scratch and sniff for brain test
Wednesday, 06 December 2006
University of Melbourne

A ‘scratch and smell’ test is set to become an important tool in identifying people who are at risk of developing brain disorders, prior to the appearance of any symptoms.

University of Melbourne researchers from the Departments of Psychiatry at ORYGEN Research Centre, Melbourne Neuropsychiatry Centre and St. Vincent’s Hospital have discovered a link between a declining ability to correctly detect and identify smells and a variety of brain disorders including Alzheimer’s disease, Huntington’s disease, Parkinson’s disease, schizophrenia, and obsessive-compulsive disorder.

In a test conducted at Melbourne Health, participants were given 40 ‘scratch and smell’ cards and asked to identify a smell from a list of four possible answers such as coffee, roses, oranges and petrol.

Those people who later went on to develop a brain disorder or mental illness had demonstrated difficulty correctly answering more than half the questions.

The research has been compiled in a new book "Olfaction and the Brain", edited by University of Melbourne researchers Associate Professor Warwick Brewer, Professor Christos Pantelis and Professor David Castle, to be launched later today.

Professor Castle, based at St. Vincent’s Hospital, said research had identified a strong link between smell and schizophrenia across all age groups

Smell linked to post traumatic stress
Wednesday, 23 April 2008
University of Melbourne

A world first study of Vietnam veterans’ sense of smell has revealed that an inability to identify smells indicates extreme symptoms of Post Traumatic Stress Disorder (PTSD).

The University of Melbourne and Austin Health study has been published in the April issue of the international journal Psychological Medicine.

The study involved conducting smell tests on 31 male war veterans with PTSD, recruited from the Austin Health’s Veterans Psychiatry Unit.

“The worse their ability to be able to name a smell, in a smell test of over 40 ‘scratch and sniff’ odours, the harder it is to manage their emotions,” said John Dileo of the University’s School of Behavioural Science, who conducted the study.

Dileo says that the difficulty Vietnam veterans suffering PTSD have, in putting the name to a smell, may be indicative of weakness in the brain pathways related to emotional processing. He says the same areas in the frontal region of the brain that are involved in identifying smells are also involved in regulating emotion.

Baby Fish "Smell Their Way Home"

Centre of Excellence for Coral Reef Studies

Marine scientists working on Australia’s Great Barrier Reef have uncovered evidence that baby fish, only millimetres long, manage to find their way to their home coral reef across miles of open sea by using their sense of smell.

Remarkable in itself, the discovery by a team including Professor Mike Kingsford of the ARC Centre of Excellence for Coral Reef Studies and James Cook University and colleagues from Woods Hole, USA, also shines a new light on how the breathtaking diversity of fish on coral reefs has arisen. This has major implications for how reefs are managed.

Yes, I inhaled, boasts a man with perfume in his blood

rederic Malle was virtually baptised in perfume. As a child, the grandson of Serge Heftler-Louiche, who founded Parfums Christian Dior, was often sprinkled with samples brought home by his mother, Marie-Christine Heftler.

She was the company's art director and Malle remembers her working with the legendary perfumer Edmond Roudnitska on Eau Sauvage, the men's fragrance concocted in 1966. "It went through stages and these stages went on to my brother, Guillaume, and I. So we were part of it. I was three, four."

Malle, 46, never knew his grandfather, a man of taste, with a talent for figures, who had helped to create such classics as Miss Dior, Diorama and Diorissimo. He died in 1959, three years before Malle was born.

And although seemingly fated to enter the perfume business, Malle did not do it until eight years ago with the creation of Editions de Parfums. It has been so successful in the US that he moved with his wife, Marie, a psychologist, and their four children to New York two years ago. It will be launched in Australia next week, when the Sydney and Melbourne outlets join his 50 other stores in 15 countries.

Malle could have gone into film, like his famous uncle, the director Louis Malle, or even banking, like his father, Jean-Francois (who financed some of Louis's early films). But he didn't automatically follow in any of their footsteps. He didn't go to work for Christian Dior like his mother. He didn't go to Harvard University to study like his father. He didn't go to film school.

Instead, in 1982, Malle veered off the Ivy League track to attend New York University and study art history and business. "I always felt in my heart that both were extremely connected. I always liked commerce and I always liked art," he says.

Bacteria Manage Perfume Oil Production From Grass

ScienceDaily (Nov. 7, 2008) — Scientists in Italy have found bacteria in the root of a tropical grass whose oils have been used in the cosmetic and perfumery industries.

These bacteria seem to promote the production of essential oils, but also they change the molecular structure of the oil, giving it different flavours and properties: termicidal, insecticidal, antimicrobial and antioxidant.

There is a lot of interest in Vetiver because it has such a dense root system.
It can therefore be used for stopping erosion or as a possible bio-fuel.

Can love change the way you smell?

. . .

"We found that using different fragrance materials to reduce the impact of a man's body odour will work on the nose of other men — but won't work on the nose of women," says Wysocki.

"A woman's nose seems to be much more tuned into ... body odours. We can find fragrances that reduce the impact of body odour from women on men," he says.

"We think that, from an evolutionary perspective, that's because women need to gain as much information as possible about potential mates because they have a very limited number of times that they can have successful pregnancies."

Subjects asked to select a prospective date from the smell of a T-shirt they had worn usually preferred the scent of a person whose immune system was genetically quite different to their own, Wysocki says, giving potential offspring optimal protection.

"Whether this goes part way to explaining the chemistry behind physical attraction, we don't know, but it may be going on at the subconscious level."

Women beware men are out to deceive you

The nose is the pathway to love
And can you trust your own body if you take a Contraceptive Pill/Chemical?

The sexiest part of a man, a Swiss zoologist has found, may be his armpits: They’re an odoriferous window on his genes.
. . .
Does that mean that women who are on the pill tend to choose mates they would otherwise avoid, with untold consequences for Western society?

Aromatic car tyres for times with the opposite sex

SEARCHING online for some new car tyres, Jon Chard came across the Kumho company. He was surprised to discover that choosing the correct fragrance of a tyre can be as important as issues like handling, ride, noise and economy. At least, that's what he thinks the product description (mytyres.co.uk - Details: Kumho KH 31 205/55 R16 91W) is telling him, though he isn't entirely sure:
"The Korean ultra-high performance tyre manufacturer Kumho presented with the scent tyres another sensational new development.
The Kumho KH 31 is in the four fragrances orange blossom, rosemary, lavender and jasmine.
The tyres are not well known to smell is one thing that is not only with a car and thicknesses much hp under the hood can specify, is the other thing.
How about times with the opposite sex instead of roses, with beguiling smells of jasmine or orange on points.
Let simply Kumho KH 31 and assemble a balance of fresh scent."

What makes dogs' noses and their sense of smell so powerful?
—Chrissie

Thanks to an impressive network of mucus-coated tubes, Rover's nose is top dog when it comes to sniffing out drugs, explosives, noxious chemicals and even disease.

"All dogs have a great sense of smell, but those with a long snout and big muzzle, like bloodhounds, beagles, labradors and German short-haired pointers are the best," says Geoff O'Neil, a senior quarantine dog handler and trainer at the Australian Quarantine and Inspection Service (AQIS).

What makes dogs' noses so powerful is that they are able to draw in large volumes of air, heat and moisten it, and expose the odour molecules to the sensory cells that make up over 50 per cent of their internal nasal area.

"Those sensory cells then transmit signals to the brain, 10 per cent of which deals only with olfaction — processing and considering smells," says O'Neil.

By comparison, less than one per cent of the human brain is devoted to interpreting smells.

The US Defense Advanced Research Projects Agency, which is trying to develop a more sensitive artificial nose, recently collaborated with Penn State University to make a fluid dynamics model of a dog's nose.

They found that the snout's geometry ensures that a smooth flow of air is delivered to a network of tiny tubes containing millions of receptors that bind to the scent molecules in the air.

The number and variety of receptors allows dogs to detect odours at concentrations as low as a few parts per trillion.

"If you were to spread out the receptor cells of a human nose, they would probably just cover a postage stamp; a dog's by comparison would cover a tea towel," says O'Neil . . .
