All life as we know of is built out of the same components (unity of bio chemistry):
carbon - nitrogen - hydrogen - oxygen - phosphorus and sulfur
If the rumor is true, then Dr. Felisa Wolfe-Simon will talk about a bacteria she found in an arsenic lake (Mono Lake) right here on Earth, arsenic-based life! Which is not using phosphorus (used to built DNA) but arsenic.
So if that is true, this will totally rewrite the definition of life as we know it when searching for alien life outside earth.
