TWiM pays tribute to Elio Schaechter, former TWiM host, blogger, and microbiologist extraordinaire, then reviews the finding that Archaea produce peptidoglycan hydrolases that kill bacteria - a form of competition.

Hosts: Vincent Racaniello, Michael Schmidt, Michele Swanson and Petra Levin.

Guest Mark O. Martin.
