Fungal spores travel farther by surfing their own wind
Date:9/27/2010

n travels outward as successive rings of spore sacs rupture in sequence. Because this happens in one-tenth of a second, the ejection seems simultaneous.

"What looks like a plume is actually a series of sheets going off," Roper said.

By tweaking their mathematical model to take account of this, Roper and Seminara discovered that cooperative ejection in sheets is a highly effective method for shooting spores long distances. The scientists continue to investigate how spore ejection is initiated, and whether and how spores can cheat to make sure that they get ejected farther than their companions.
