Remember that claim, about a year ago, that a scientist had discovered arsenic-based life forms right here on Earth? It seems that other scientists are having trouble reproducing that research. It doesn’t necessarily mean that the original scientist was wrong, but it puts the assertion in doubt.

If it does turn out to be wrong, it’s too bad, really. I was hoping that we’d found our first truly alien species (chemically speaking, at least) literally right in our back yard. Well, there’s always science fiction. 🙂
