Arsenic and Old Lace?

     Unfortunately, this is not a reference to the old film. This is about some new research that has been taking over the internet! There has been some bacteria found that is using Arsenic instead of Phosphorus.Arsenic is usually thought to be poisionous, as mentioned in the movie, but something is putting it to use. This is a huge discovery which can lead to drastically changing how we are viewing, researching, and teaching about the chemistry of life.
