This is Scientific American's 60 Second Science. I'm Steve Mirsky, got a minute?


The Meridiana Planum region of Mars once had water that was really soft and highly acidic, conditions in incredibly hostile to any life forms that we know about. So any organisms that might once lived in that area on Mars would really have the * arts. But why do we know so much about the likelihood of particular environment-support life. Mars scientists * you and me in our propensity 1 to eat. Harvard professor of Earth and Planetary Science's Andew Knoll 2 spoke 3 to reporters Friday at the AAAS meeting. "The food preservation 4 industry depends hardly on people knowing the kind of ionic tolerances 6 of microorganisms. So this isn't some * saying that the Mars scientists will pull a paper off to shelf. How is the papers out there on the tolerance 5 of microorganisms and it's not because most scientists are worried about *; it's because they are worried about *" so one science feeds another.


Thanks for the minute for Scientific American's 60 Second Science from the AAAS meeting in Boston. I'm Steve Mirsky.
