Bacteria stir debate about 'shadow biosphere'

Washington Post (Article)
I think it's a good thing that we found a new way of looking at life forms; only draw back is that we don't have a head start on this information and it has taken this long to find this information.

Will I be getting a refund in my chemistry or biology class? hmmm I don't think so but hey kudos to the scientist.

When Technology is available at far reaches; we know that we can even tag a bacteria even if it's hidden in 'shadow biosphere'.
