The 2017 Astrobiology Science Conference in Mesa, Arizona is just over a month away (April 24–28), and the abstracts are now available at the website. As a reminder, discounted registration ends March 27th.

In addition to the session I’m co-organizing with Eric Libby, there is another whole session on “Cellularity, Multicellularity, and Endosymbiosis,” organized by Aaron Goldman and Mary Droser. There is also a session on “Experimental Microbial Evolution,” chaired by Shelley Copley and Frank Rosenzweig.
