Hi dx
re. your #28, I don't know anything more than any of us regulars on the marsroverblog, but I think that Levin found life in the Viking LR experiments and I'm just extrapolating from there.
Re. the putative water borne squigglees, the OM images were not in an aqueous medium and hence the image could not equate to that of almost any soil that you could put under your microscope on Earth. That soil would be filled with nematodes, etc, that would be immediately obvious through their morphology and perhaps movement depending on the medium you placed the soil in. Here, the situation is quite different.
