Two apparently unrelated systems on vastly different scales – fairy circles in the Namibian desert (left) and microscopic skin cells (right) – appear to share a similar pattern, which is very, very unusual.
Namibian fairy circles are large barren patches of earth ringed by short grass dotting the desert like craters on the moon or giant polka dots. No one knows how they form.
The distribution of Namibian fairy circles (red, yellow and blue bars) with four, five, six, seven, eight and nine neighbors (indicated by polygon class) is essentially the same as skin cells (black bar) – statistically indistinguishable. The patterns...
Haozhe Zhang, a PhD student now at Iowa State University, and OIST Professor Robert Sinclair investigated the spatial patterns of Namibian fairy circles and skin cells when Zhang was a research intern at OIST in 2013. Sinclair had wondered if the circles...

Typhoon Choi Wan captured by satellite as it passed through the Eastern Philippine Sea in September 2009.
Heaviness of rainfall around the typhoon’s center is marked by red, green and blue in that order. Areas with the heaviest rainfall, in red and green are around the central column. The Tropical Rainfall Measuring Mission (...
