Researchers have discovered the presence of significant numbers of living microorganisms–mostly bacteria–in the middle and upper troposphere, the part of the atmosphere four to six miles above the Earth’s surface. In other words, the clouds are filled with germs! Do they fall to Earth when it rains? (NOTE: Subscribers can still listen to this incredible show).

However, some of the transformations that take place are very fast, which only adds to the high strangeness.
