I’ve got to admit that I was a little disappointed not to see the lichen experiments referenced in the paper the article cited, although the molecular sequences cited are still interesting.
A little further down of the same Science Daily page is a link to an article “Tiny Animals Exposed To Outer Space”. As it’s evidently from 2007 though, I suspect they didn’t fare too well. It will be interesting to dig up something on this, as I’ll try to do.
