🧪 🧫 🥼 Hey, PIs: Have you lost chance to publish bc former students went AWOL? A PI I know can't publish bc student lost interest/can't be reached. Paper is blocked, bc journals want all authors to OK. PI asked 3 colleagues: all had same experience, i.e. had to bin data. How big is that problem??

Der Schwarze Tod, mit dem die größte Pandemie in der Menschheitsgeschichte ihren Ausgang nahm, wütete in Europa zwischen 1346 und 1353. Vor dem Schwarzen Tod hatten bereits die Steinzeit- (grün) und die Justinianische Pest (orange) Europa heimgesucht. Die Hongkong-Pest breitete sich später von Europa nach Ostasien aus (blau).
