Away with the fairies

According to an article in New Scientist researchers investigating the favoured explanations for the existence of so-called Fairy Cirlces in Namibia (mysteriously empty and barren discs of soil anything up to 10 metres in diameter) have found that none of the three principal theories actually hold any water. So, the cirlces are still mysterious and it’s back to the drawing board for a new explanation for their existence. Or as one scientist put it, at the moment we’re left with the Faeries option.
