July 14, 2013 — Is space really the final frontier, or are the greatest   
   mysteries closer to home? In cosmology, dark matter is said to account for the   
   majority of mass in the universe, however its presence is inferred by indirect   
   effects rather than    
   detected through telescopes. The biological equivalent is "microbial dark   
   matter," that pervasive yet practically invisible infrastructure of life on   
   the planet, which can have profound influences on the most significant   
   environmental processes from    
   plant growth and health, to nutrient cycles in terrestrial and marine   
   environments, the global carbon cycle, and possibly even climate processes. By   
   employing next generation DNA sequencing of genomes isolated from single   
   cells, great strides are being    
   made in the monumental task of systematically bringing to light and filling in   
   uncharted branches in the bacterial and archaeal tree of life.
