Paul Davies of Arizona State University poses for the Associated Press prior to his lecture in the Royal Society in central London, Tuesday Jan. 26, 2010. For the past 50 years, scientists have been scouring the skies for radio signals from beyond our planet, hoping for some sign of extraterrestrial life. But one physicist says there's no reason alien life couldn't already be lurking among us or maybe even in us. Davies had told the conference held on the society on the hunt for alien life and that life may have developped on earth not once but several times. Davies said the variant life forms _ most likely tiny microbes could still be hanging around "right under or noses or even in our noses."

This undated photo released by the Royal Society via PA shows Sir Isaac Newton. An 18th-century account of how a falling piece of fruit helped Newton develop the theory of gravity is being posted to the Web, making scans of the fragile paper manuscript widely available to the public for the first time. Newton's encounter with an apple ranks among science's most celebrated anecdotes, and Britain's Royal Society said it was making the documents available online Monday, Jan. 18, 2010.
