This flight through the eyewall caught Earl just as it was intensifying from a Category 2 to a Category 4 hurricane. Researchers collected air samples on this flight from about 30,000 feet over both land and sea and close to 100 different species of bacteria.

Microbes are known to be able to thrive in extreme environments, from inside fiery volcanoes to down on the bottom of the ocean. Now scientists have found a surprising number of them living in storm clouds tens of thousands of feet above the Earth. And those airborne microbes could play a role in global climate.

In St. Louis, Oakville received three and a half inches of rain, the most in the metropolitan area.  But National Weather Service Meteorologist Jayson Gosselin said it will take much more rain to snap this summer's historic drought.

Soil bacteria may be helping to make disease-causing bacteria resistant to antibiotics.

That’s according to a new study out of Washington University.

Lead researcher, microbiologist Gautam Dantas, says he and his colleagues found seven genes in farmland soil bacteria that are identical to genes in human pathogens – and that provide resistance to a wide range of antibiotics.
