The article linked here was published last week out of the University of Virginia and alludes to the challenges faced by the sheer magnitude of data--and nearly infinite interactions--that must be assessed and considered when trying to understand the human microbiome.  Good job UVA, and kudos to Dr. Papin and Mr. Medlock for "taking a step back."  This may be an example of "one step back and two steps forward"!
Onward!
