The NExSS co-sponsored blog Many Worlds has a good post, The Search for Exoplanet Life Goes Broad and Deep, on the recent Upstairs Downstairs: Consequences of Internal Planet Evolution for the Habitability and Detectability of Life on Extrasolar Planets workshop, held at Arizona State University.

The workshop was sponsored by NASA’s Nexus for Exoplanet Systems Science (NExSS), the NASA Astrobiology Institute (NAI), and the National Science Foundation.
