All known life requires liquid water and a source of energy and
bioelements. I will show that natural ice satisfies these re-quirements

concentrate at triple junctions of grains in ice, forming a net-work of
liquid veins a few microns in diam-eter (see picture). I will present
evidence that terrestrial microbes take advantage of such icy habitats.
Some or all of the following topics will be discussed:
