Jennifer Loveland-Curtze, the lead researcher on the Penn State team, said the new species adds one more sliver of enlightenment to the vast and mostly unexplored universe of microorganisms.

One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
