Russ, you had a small typo in your Shrödinger quote.
Instead of extracting energy, Schrödinger actually defined living systems
as extracting negative entropy from the environment:
the only way a living system stays alive, away from maximum entropy or
death is to be continually drawing from its

I don't think anyone was being defensive. Personally, I was just very

On a tangent, however, I found this article interesting:

This (from another

Arsenic falls directly below phosphorus on the period table, and thus has
many similar chemical properties. In contrast to relatively stable

Hi, Russ!
One reason it is important is that it demonstrates that life as we
know it has a broader definition that previously thought.
It means that if we find an earth-like planet out there, except with
more arsenic than phosphorus -- in other words, a poisonous-to-us
planet -- we might still

Following Glen, Roger, and James, and also wondering why Nick is being a

I believe the report is of interest for
showing an organism that uses arsenic in interesting ways, but it gets its
magical-shininess (i.e. Science worthiness) for showing an organism that does
not use phosphorous.
