It may be a gamechanger in the search for an alien life. NASA scientist unveiled the discovery Thursday that it says redefines life as we know it, the existence of a type of bacteria that thrives on toxic chemical arsenic. NASA scientist F. Wolf Seman.
And if there's an organism on earth doing something different. We've cracked open the door to what's possible for life elsewhere in the universe. And that's profound, and to understand how life is formed, and where life is going. This microbe substitutes arsenic for phosphorus in its basic biomolecules, and what else might we find? What else might we want to look for?
The finding in the salty lake near Yosemite National Park in California shows just how little scientists know about the variety of life forms on earth, and may greatly expand where they should be looking for life on other planets.
John Decker, Reauters.
