Even though Phoenix was assembled in a special clean room to minimize bacterial contamination, and its arm, which would have direct contact with Martian ice, was heat-sterilized before launch, it's likely that dozens or more species of microbes hitched a ride on Phoenix's 10-month trip to Mars. Once on Mars, it's possible that bacteria shielded by the structure of the spacecraft from the harsh Martian UV radiation could stay alive, in dormancy, for hundreds of thousands of years. And if native microbes do exist on Mars - nothing has been found yet, but scientists hold...

More than 40% of people searching online for spa services are hunting for something to clean out the pipes, according to SpaFinder, a consumer resource for spa information; that's almost 50% more than in 2007.

...campus by a coal company executive yesterday evening. The activists, members of Rising Tide Boston, a self-proclaimed environmental and social justice group, came to the front of the room during the talk’s question and answer period and unfurled a banner stating “clean coal is a dirty lie” while listing grievances with coal as an energy source. As two of the activists held the banner, another questioned the speaker, CEO of Arch Coal Steven F. Leer, on the viability of coal as a solution to climate change. When moderator Daniel P. Schrag...
