The eye of Hurricane Earl in the Atlantic Ocean, seen from a NASA research aircraft on Aug. 30, 2010. 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.

Terry Lathem, a graduate student in Georgia Tech's School of Earth and Atmospheric Sciences, takes notes aboard a NASA DC-8 aircraft gathering samples of microorganisms in the atmosphere.
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.
Tuesday marks the 50th anniversary of the death of the poet Robert Frost, famous for such poems as "Stopping by Woods on a Snowy Evening" and "The Road Not Taken."

Reading always seemed to be the most private of acts: just you and your imagination immersed in another world. But now, if you happen to be curled up with an e-reader, you're not alone.
Data is being collected about your reading habits. That information belongs to the companies that sell e-readers, like Amazon or Barnes & Noble. And they can share — or sell — that information if they like. One official at Barnes & Noble has said sharing that data with publishers might "help authors create even better books."

If doctors would just pay attention to how much things cost, they might be more careful when ordering tests for patients, right?
Well, that's the theory behind some research and projects to cut wasteful health spending. But a study at Johns Hopkins Hospital found that changing doctors' behavior may be not be as easy as simply making them aware of prices.
