Toxin in soil may mean no life on Mars

My favorite thing about reports like this is that we always assume life has to be like us.
NASA’s Phoenix lander has discovered a toxic chemical in soil near Mars’ north pole, dimming hopes for finding life on the Red Planet, the probe’s operators said Monday.
The chemical, perchlorate, is an oxidant widely used in solid rocket fuel. Researchers are still puzzling over the results and checking to make sure the perchlorate wasn’t carried to Mars from Earth, the University of Arizona-based science team said.
