CAMBRIDGE, Mass., Dec. 23, 2008 -- The reproductive spores of many species of fungi have evolved remarkably drag-minimizing shapes, according to new research by mycologists and applied mathematicians at Harvard University.
In many cases, the scientists report this week in the Proceedings of the National Academy of Sciences, the drag experienced by these fungal spores is within one percent of the absolute minimum possible drag for their size. But these sleek shapes are seen only among spores distributed by air flow, not those which are borne by animals.
