An article that came out today: The truth IS out there: British scientists claim to have found proof of alien life - Science - News - The Independent
The basic summary is they sent a balloon up to the upper atmosphere to collect samples. It returned with unusual particles that the scientists believe are living (or once-living) organisms. They claim there's no mechanism by which such organisms could have got there from Earth, so they most likely came from a comet. They mentioned in "an earlier experiment" they found similar particles which contained DNA, which implies if the life forms did come from space that all life on Earth originated from space (because it's highly improbable that DNA would evolve twice independently). Apparently there is a counter argument that the particles could have come from a volcanic eruption. The man who found the particles argues that debris from the last volcanic eruption (I think the Iceland one?) would have settled by now. The results are published in a scientific journal, however the article mentions this journal has had its reputation "called into question more than once".
