Alien life 'may exist among us'

BBC NEWS: "Never mind Mars, alien life may be thriving right here on Earth, a major science conference has heard.
Our planet may harbour forms of "weird life" unrelated to life as we know it, according to Professor Paul Davies, a physicist at Arizona State University.
This "shadow life" may be hidden in toxic arsenic lakes or in boiling deep sea hydrothermal vents, he says.
He has called on scientists to launch a "mission to Earth" by trawling hostile environments for signs of bio-activity.
Weird life could even be living among us, in forms which we don't yet recognise, he told the American Association for the Advancement of Science (AAAS) meeting in Chicago.
"We don't have to go to other planets to find weird life.
"It could be right in front of our noses - or even in our noses," said the physicist.
"It is entirely reasonable to expect we will find a shadow biosphere here on Earth.
"But nobody has actually taken the trouble to look."
