Gauger reported on her work at the "Wistar Retrospective Symposium" held from June 3 through June 7, 2007 in Boston, Massachusetts. As reported by Daniel Brooks, "...she discussed "leaky growth," in microbial colonies at high densities, leading to horizontal transfer of genetic information, and announced that under such conditions she had actually found a novel variant that seemed to lead to enhanced colony growth. Gunther Wagner said, "So, a beneficial mutation happened right in your lab?" at which point the moderator halted questioning." Gauger herself has reported a different take on this meeting, saying that the point was not whether there was a beneficial mutation (which Gauger agrees there was) but whether or not the organism had manufactured a new way to make biotin, which it had not (it had merely been able to better scavenge it from the environment). Additionally, Brooks implied that the questioning was cut short because of the question, while Gauger holds that this was simply an amusing question at the end of the session.
