Today, in the 16th ScienceBeer, Stefan was our Science Brewer. Stefan is a PhD student in TU-Dresden and works on SELF-ORGANIZATION OF BIOLOGICAL STRUCTURES. Stefan introduced us to the fascinating world of DNA origami, the art of turning DNA strings into useful biological tools. With a handful of live demonstrations, Stefan walked us through the process. The evening was full of surprises and surprising facts. Do you know how in earlier times women did their pregnancy test? Do you have any idea about recent achievements of biologists? Well, then don't miss the Stefan's talk. Thank you Stefan.
