NASA Disovers New Lifeform

[xoxoxoBruce]

Instead of using phosphorus, the bacteria uses arsenic for all its building blocks.

Arsenic being poison, it sounds like the "life" forms are not food. Throw them back... next.

As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it.

Yeah, if we don't find life forms, we'll expand the definition until we do.

Eureka, I've found it!
That's the rock I tripped over yesterday.
That was yesterday, today it's a lifeform.

I can see expanding the markers for initial searching so they don't overlook something, but don't they have a certain list of qualifications, that constitute a lifeform, a definition of a lifeform? Like it has to grow, or reproduce, or even eat, I mean it doesn't have to write sonatas, but something.
