The scent of lily of the valley cannot be easily bottled. For decades companies that make soap, lotions and perfumes have relied on a chemical called bourgeonal to imbue their products with the sweet smell of the little white flowers. A tiny drop can be extraordinarily intense.
If you can smell it at all, that is. For a small percentage of people, it fails to register as anything.
The tongue does not just detect taste, but might pick up on odours too, according to research shedding new light on how we perceive flavour.
The tongue has long been known to detect whether something tastes sweet, sour, salty, bitter or umami (savouriness) thanks to cells that carry taste receptors – proteins that interact with particular molecules in food.
Twenty-five sommelier students outperformed an untrained ‘control’ group of 29 people at identifying a range of common wine aromas within around two months of education, according to a study recently published in the journal Chemosensory Perception.View Here
Will new airplane aromas help make flights more pleasant?
United frequent flier Katherine Wenglikowski loathes the stinky smell of public bathrooms, but she was pleasantly surprised by what she found in the lavatory on a recent United Airlines flight from Los Angeles to Newark, N.J. The aroma of grapefruit.

Neuroscientists have found a pathway in the brain where taste and pain intersect in a new study that originally was designed to look at the intersection of taste and food temperature. This study was the first time researchers have shown that taste and pain signals come together in the brain and use the same circuitry.Read More
Doctors at Massachusetts Eye and Ear say they’ve placed electrodes in the nose to stimulate people’s brains and cause them to smell onions and other smells that weren’t there, in an experiment that could be a first step toward a treatment someday of anosmia, the loss of the sense of smell.Read More
The popularity of sparkling water has been bubbling up in the United States recently — Americans will buy more than 800 million gallons of it this year, according to one estimate.
But why do people like it?
Harvard Medical School researchers at Massachusetts Eye and Ear have, for the first time, induced a sense of smell in humans by using electrodes in the nose to stimulate nerves in the olfactory bulb, a structure in the brain where information received from the nose is processed and sent to deeper regions of the brain.Read More
