In Namibia, little bare patches form in the grass after the rainy season. These are called ‘fairy circles’, and no one knows what causes them to form. A biologist at Florida State University named Dr. Walter Tschinkel has begun to tackle the problem. He first observed these fairy circles while on vacation, and thought they must be caused by termites. However, no termites were found. Since then, he’s been trying to understand the circles, but has not quite deciphered their cause yet. He did discover that they have a lifespan that averages about 41 years, and he is continuing to work on the problem. For now, the fairy circles will just have to remain a mystery.
