Hello everybody, I've been a long time lurker at UMSF, mainly because I didn't feel I had much to contribute, but I've finally run across something thats made me curious enough to step into the light. Space.com and Astrobiology.com are both running stories on how the viking life detection experiments are consistent with the presence of microbes with hydrogen peroxide as their internal fluid instead of water. I've got no background in chemistry but I have first hand experiance of how unpleasant hydrogen peroxide is (I once spilt some on myself and I stil have a faint scar on my hand) so I was wondering if someone could give my the short words and big pictures explanation of how such a creature would work? If this is already being discussed elsewhere many apologies.
