Odd Bacteria Incorporate Arsenic Into DNA Structure

I was visiting a lake that I used to go to as a kid and found this out and I thought I'd share it:

According to NASA there is a bacteria living in the lake that can not only survive high concentrations of arsenic, but it can actually use it in it's DNA structure. I don't know much about this stuff but it seemed pretty interesting to me.

They might not be actually doing that. cn
