While presenting a paper, be sure to dedicate 25-30% of your talk for the introduction. During the introduction you need to explain the concepts, experimental techniques, and other elements required to understand and follow the presentation. Leave 10-15% of the presentation for the conclusion and critical discussion, and use the rest of the time to present the experimental data. Remember that you DO NOT necessarily need to present all the figures from the paper. If there are too many, choose those figures that will make a nice and complete story.
Paper with a definition of "lipid rafts".

JC Today is canceled. The University will close at 12PM. We will continue with the established schedule and move Seena's presentation to the next available open slot.
In order to exercise greater responsibility for
critically assessing articles suggested for presentation, we are going to institute a
new procedure for selecting articles.
At the journal club, one week in
advance of your full presentation (preferably two or more), you will
justify and defend to the group the suggested articles with 1 powerpoint
slide per suggested paper (no animations)-- no more than three suggestions (slides). EXAMPLE
We'll decide at that time, which paper will be developed into a full
presentation.
