After a long day, there is nothing more refreshing than hearing the pop and fizz of a freshly poured beer. As you pour the frothy liquid into a glass, you instantly smell the unique, pungent aroma.
According to new findings, beer lovers are not the only ones attracted to the smell. Scientists have found that because of the aroma found in yeast, fruit flies are also attracted to booze.
Anyone who has ever worked in a restaurant kitchen or bar knows that pesky fruit flies sometimes come with the territory. However, researchers from the University of Leuven and the Flanders Institute for Biotechnology in Belgium have discovered that smell is linked to a mutually beneficial relationship between yeast and fruit flies.
It turns out that yeast and fruit flies are involved in a "smell-based collaboration."
