No life has yet been found on Mars, but it is exciting to explore the circumstances under which it might be possible. A team led by the Technical University of Berlin (TU Berlin) with the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) has studied the cellular processes that regulate the adaptation of microorganisms to perchlorates. If microorganisms could genetically adapt their stress response to this salt, which occurs in some deserts and on Mars, their survival on the Red Planet might be possible.
