The team found similar results for the six different scent molecules they analyzed.

A machine called a mass spectrometer measured levels of scent molecules as far as 4.5 meters away from the flowers.

Because the binding of scent molecules must be reversible for the nose to be reusable, only weakly binding chemical receptors can be used, which limits sensitivity and selectivity.

While foraging for food, insects detect floral scent molecules in the air.

A standard rule of thumb is to diffuse for 15 to 20 minutes, which is more than enough time to saturate a standard - size room with scent molecules.

Our noses are packed with olfactory receptors, each of which is tuned to a precise scent molecule.

Air pollutants interact with and break down plant - emitted scent molecules, which insect pollinators use to locate needed food, according to a team of researchers led by Penn State.

Changes to beta - myrcene and other scent molecules as they interacted with the pollutants meant that insects would have to spend longer in search of a meal.

The largest qualm about ultrasonic diffusers is that the aromatic scent molecules are diluted with water, which means that top notes, like citrus oils, are extremely volatile and faint in smell.

Their forked tongues pick up scent molecules that the animal transfers, via specialized ducts in the mouth, to the Jacobson's organ, which can detect where the scent's source is located.

Some scent molecules act as deterrents to drive away blossom - munching predators.

Chemical compounds in pollution interfere with the scent molecules produced by flowers, making it harder for pollinating insects to find their way.

This happens because the chemical interactions decrease both the scent molecules» life spans and the distances they travel.

The scent molecule alpha - pinene, which survives nearly 40 hours in an ozone - free environment, survived fewer than 10 hours when ozone rose to 60 parts per billion and only 1 hour when ozone was at 120 parts per billion.

In an ozone - free environment, it took 10 minutes for 20 percent of foragers to find the scent molecule beta - caryophyllene.
