Has Peru's mysterious illness been explained? Seems like. The New York Times is reporting that a meteor did, in fact, hit the ground, but rather than alien microbes taking a ride through space, or radiation poisoning, it seems like arsenic from the ground water is actually the culprit. The theory is that when the hot meteor hit, it dug far enough into the ground that the local ground water, and everything it's contaminated with, steamed up in a big cloud which made the locals sick. Until I hear a better story, I'll buy it.
