Living in Arsenic

SUMMERY
In a new study, scientists have found a strain of bacteria that can live in arsenic. Arsenic is just under phosphorus on the periodic table of elements. But, unlike the necessary building block of life element phosphorus is, arsenic is deadly to almost all species on earth. In Eastern California, Mono Lake, is an alkaline and hypersaline lake with a high concentration of dissolved arsenic. In this death pit, scientists have found a strain of bacteria that's not only living in the arsenic rich habitat, but using arsenic as a building block to it's life force in a way similar to phosphorus.
OPINION
I have to wonder now if we're going to be able to find a way to use this bacteria as a weapon. Using it as a bioweapon where we can infect an area with a bacteria that uses arsenic in it's essesence would be not only evil and coruptive, but also tactical. It's interesting that they've evolved to live in this condition, but it's very impressive that they've been able to adapt so well.
