The Truth hidden in a good smell of Rain

Fresh smell rising from the ground right after the rain. Nobody would imagine that - this might be a little odorous smell. However, although rain is mostly harmless, it sometimes diffuses diseases by releasing bacteria into the air.

Group of mechanical engineering technician who worked on elucidation of the process is, how the smell of soil is ground from the nose of the paper that describes how to reach, announced on Nature magazine.

So far, the smell after the rain is, called geosmin chemical, of the earthy with bright red vegetables red beet taste cause, is that you may have known. And finally scientists have figured out how this smell diffuses into the atmosphere by a small drop of rain .

National Public Radio (NPR) reports as follows:

Using a high-speed camera and a fluorescent dye, if you take a picture of a drop of water falling into the different types of soil filled with bacteria, drop the microorganisms into the atmosphere are flipping that has been observed.

When raindrop hits the ground at an appropriate speed, it traps fine bubbles more than the hair of a person .

Like air bubbles under the container at the bottom of the pool, those air bubbles rise and rupture as they reach the surface .

When the foam bursts, into a small water jet, are sprayed into the air, sometimes carrying bacteria.

The research team experiment with only one drop of rain, thousands have discovered that in a small splash hundreds of bacteria including and things are sprinkled. This bacterium can survive for almost an hour in almost invisible droplets, and once it floats in the air it is blown by the wind. According to Mr. Cullen Buie, one of the project's researchers, the next step in the study seems to be to investigate how far the bacteria can move .

Bacteria do not cause harm to people, so it is not a big deal. However, from the British scientist's Bouilet's we began this study, Southeast Asia and is an infection common human beast in northern Australia melioidosis because has been informed that, to expand to be a rainy season. Although this infection can be treated, it is a scary disease with a mortality rate of 90% unless proper treatment done with antibiotics.

It is not the first time for this research team to focus on the relationship between the spread of glanders and rainfall, but it is a study to deepen understanding about rain. Luckily, it is an extremely rare illness. It seems to be okay to take a deep breath of delicious air to the chest as it is raining.
