The last stations have been completed – this had to be celebrated properly. More than 80 guests came to the celebration and followed the small stage program with the science show “Forschperspektive”, who welcomed the guests with a walk act and introduced the “Nano Earworm” on stage. Prof. Tim Henning from the Philosophical Seminar Mainz discussed nanomedicine with Prof. Katharina Landfester on the “Red Couch”. Prof. Henning looked at the topic from an ethical point of view, which could mean great progress for people's health, but could also harbor dangers.
