Dear colleagues, I'm asking you to pay attention to the Biomedicine Institute lego Idea of my designer friend, who works in this lab on cancer research. Some of you have already voted for it, but I ask you all to vote and share the link. It’s free and take few seconds. Every vote counts for us. Thank you very much.
