Arsenic in DNA?

Arsenic Article
I just read an article in the Wall Street Journal about Arsenic in DNA. This is profound, if true, and a bit scary.

Arsenic? A  poison? Found incorporated in the genetic code of life. I was shocked. Researchers are suggesting this is new evidence that there is life outside of planet earth. This may redefine the essential elements of life.
