It has long been said that air (which others call argon) is the source of life. This is not in fact the case, and I engrave these words to describe how I came to understand the true source of life and, as a corollary, the means by which life will one day end.Ted Chiang's excellent short story "Exhalation" won a Hugo last night. The setting is an alien world where an argon-breathing metal scientist seeks to understand his world and himself. Admittedly, it technically isn't about biology - at least not carbon-based life - but if you read it for yourself I think you'll see the similarities.
