Far below the ocean floors there are chthonic aquifers in which hitherto unknown microbes prosper thanks to their ability to “breathe” sulfates. Scientists and engineers at the Center for Dark Energy Biosphere Investigations at the University of Southern California have developed probes that descend to the seafloor and drill sealed holes through the sediments down to water-carrying rock layers. There they have collected samples of yet-unclassified microorganisms that flourish in that peculiar environment despite its lack of oxygen and light.
Here is yet another proof of how life finds ways of adapting to hostile environments; a comforting thought when I look with hopeful eyes at the barren Mars. Take a look at the picture below and read more here — link >>>
