comment What elements are a possible basis for life?
For the time being, I think the best bet is to regard things as life if they look like life as we know it on Earth. It is dreadfully anthropocentric but at least its a starter until we really understand what separated living from non-living.

comment What is the oldest example of DNA identified?
My understanding was that DNA in non-living matter had lifetimes of thousands of years, not millions. How did such ancient DNA manage to be preserved? Does this result hold up?
