The camp part was about nothing less than the biological basis for infectious diseases, their diagnostics and control. The participants looked at the organismic as well as the cellular and molecular level and conducted experiments with, among others, a tumor cell line (from the research group of Prof. Dr. Matthias Dobbelstein), bacteria, phages, restriction enzymes, the gene scissors CRISPR/Cas and antibodies. Participants who had studied Physics in Life Sciences the week before explained the basics of fluorescence microscopy to their fellow students. XLAB lecturer Dr. Kristina Wiege is herself fascinated by how key techniques in medical diagnostics, research and treatment have been developed from "natural" biological mechanisms and passes on this fascination: During the third Science Camp week, there was a concentrated working atmosphere and high motivation despite the summer temperatures.
