Once again, life has been found in an environment that would be deeply inhospitable to most organisms living on this planet.
Fed by waters that pass through 600 meters of permafrost, the sub-zero, salty, virtually oxygen-free Lost Hammer Spring in the Canadian Arctic is one of the harshest places on Earth. Even here, however, life finds a way.
From deep below the permafrost, water with less than one part per million of dissolved oxygen, around 24 percent salinity and at temperatures around minus 5 degrees Celsius seeps up to the surface. Imagine trying to live in that. You couldn't, not without significant help.. Given its similarity to the maybe-lakes on Mars, microbiologist Elisse Magnuson of McGill University in Canada and her colleagues wanted to see if Lost Hammer Spring might be one of them. Although it wasn't easy.
"The microbes we found and described at Lost Hammer Spring are surprising, because, unlike other microorganisms, they don't depend on organic material or oxygen to live,""Instead, they survive by eating and breathing simple inorganic compounds such as methane, sulfides, sulfate, carbon monoxide and carbon dioxide, all of which are found on Mars.
