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

This (from another articlehttp://www.the-scientist.com/news/display/57851/#ixzz16zxXUGXe) looks like a significant part of the answer. Arsenic falls directly below phosphorus on the period table, and thus has many similar chemical properties. In contrast to relatively stable phosphorus-based

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 pill 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.
