This was the All Scientists Meeting for the Long Term Ecological Research Network.
Nope. It was from the American Society of Microbiology 2012 General Meeting.
ASM Journal Platform
It is a rather large meeting with 10,000+ attending the keynote addresses. I believe it is the largest meeting for scientific research in microbiology in the US. The picture is for one of the poster sessions, of which there are usually 3 (if memory serves). There are also oral presentations throughout each day.
I got the feeling of some sort of competition, though? Is that just the anxiety of having your work judged by your peers? Or is this setup meant to actually "win" something as well?
There is definitely competition, especially between labs studying the same bug. There are also awards given out for the best posters, orals, etc.
