The news is out on NASA’s recent exciting discovery. No, it’s not alien life on Titan, and it’s not the answer to David Bowie’s question about life on Mars either. It’s pretty amazing, though, and might well change things for writers of hard science fiction.
Gizmodo reports that bacteria whose DNA is made with arsenic in place of phosphorus have been found at Mono Lake in CA. This changes a lot about our understanding of how life can operate. The official NASA announcement is not out yet, but it will probably provide a lot of rich material for SF authors to use in future books.
On a personal note, I remember from my California days that “Save Mono Lake” bumper stickers were popular. I’m glad we saved as much of it as we could. A photographer friend of mine, Joe Decker, has a photo gallery of the natural beauty of Mono Lake, though none of us knew it would hold such an amazing secret.
