In this week’s issue (March 10, 2014) of the Proceedings of the National Academy of Sciences (PNAS), ESD’s Ecosystems Biology Program head Janet Jansson and fellow scientists from the Joint Genome Institute and Michigan State University report the largest soil DNA sequencing effort to date. As stated in the DOE Joint Genome Institute’s description of the article, what emerges from this effort is a ”simple, elegant solution to sifting through the deluge of information gleaned, as well as a sobering reality check on just how hard a challenge these environments will be.”
