You think Captain America's recent resurrection was incredible? That's nothing compared to a bacterium in Greenland that just came back to life after 120,000 years. It was kept on ice three kilometers deep inside a glacier, and researchers looking at it now believe it may resemble life on another planet.

"All we can say is that because ice is the best medium to preserve nucleic acids, other organic compounds and cells, the potential for finding them in these environments is quite high because of the cold," says Loveland-Curtze.

Maybe that's why Captain America had no problem coming back the first time in the 1960s after being suspended in a block of ice -- or why another frozen organism managed to come back to life after 8 million years.
