Do you like the smell of fresh earth? Does a whiff from a freshly-plowed field or just-tilled garden improve your mood? Well it might soon be possible for you to get that fresh earthy smell even in your uptown apartment. That earthy smell comes from the combination of two harmless chemicals that are made by bacteria in the soil. Scientists report that they have successfully isolated the bacterial genes responsible for synthesizing those chemicals. Now maybe even those far from the farm (but who like the scent) can experience the scent, and without the dirt!
