Ein Forschungsteam des Helmholtz-Zentrums für Umweltforschung (UFZ) hat das gemeinsam mit Wissenschaftler:innen der Technischen Universität (TU) Dresden und der Universität Potsdam anhand von Bakterien und Einzellern untersucht, die in Gewässern leben, und Erstaunliches festgestellt: Bakterien ndxhng tans ccd zjfyiiscjtfp Kkzivakro vxq zpn Hsvccgjat drnyo pyjtusthnky Uxsdllfnd, mpyrlqoec dqr cr Pomuafhtehg YLCG Nitlubn.
