Well, automaton is being a little harsh. For those of us who intend to do research in our careers, journal club is a way to learn how to do good/bad science. Usually, people take turns presenting a paper from a high-yield journal (Science, Nature, JBC, Cell,...) At first it might seem like people are being spiteful, but it's an important skill to learn to pick apart an article. That way, when our time comes around, we are aware of what type of experimental design is effective and what isn't. Its a great way to discuss science, breakthrough work, and get fed (most importantly! 🙂)
