Spiegel online reports a Pubmed listed study in the Deutsche Medizinische Wochenschrift by 14 and 12 year old authors. Having supervised such a study at Mini-München I believe that this not so spectacular as the DMW is now marketing this event. The DMW has been one of the most renown journals here. As a medical student I even had a full subscription while today the impact is being low (0.58) and needs some marketing tricks.
