I hate to point this out, but they look very much like ordinary red blood cells.

From the article:

Other theories have implicated fungal spores, red dust swept up from the Arabian peninsula, even a fine mist of blood cells produced by a meteor striking a high-flying flock of bats.
Louis and his colleagues dismiss all these theories, pointing to the fact that both algae and fungus possess DNA and that blood cells have thin walls and die quickly when exposed to water and air.
More important, they argue, blood cells don't replicate. "We've already got some stunning pictures -- transmission electron micrographs -- of these cells sliced in the middle," Wickramasinghe says. "We see them budding, with little daughter cells inside the big cells."

Perhaps they are the remains of aerosolized Islamofascists who once resided in Iraq and Afghanistan. Pop off a MOAB when the wind is right, and who knows where bits and pieces of Mahmood could end up?

Do a DNA test. Maybe we got Osama with one of those Moabs after all.
