    Fascinating link not_Fritz. So it seems that water may not be necessary for the formation of life, and in fact, may inhibit it. And the researchers apparently postulate that RNA cannot exist at first in the presence of water, so at some time we may assume that the building blocks of life occurred before liquid water in the presence of gamma rays?

    Yes. That millionfold increase in the abundance of formamide because of nearby gamma ray sources would seem to be necessary though. I think that what this does for the likelihood of life forming elsewhere is interesting but unclear. Europa has a high radiation environment so a plus up there. For Earthlike planetary life it's really murky though.

    There is a certain humor too in life switching to exploit water after exhausted the limited ecology of formamide. Too bad humans aren't going to be able to do that on any scale that isn't de facto genocidal.

    Sorry about the typo in the thread title. I keep typing off ny one and the auto correct has amusing responses.....
