Wissenschaftler der Uni Mainz haben in Namibia und anderen Wüstengebieten seltsame Gesteinsröhrchen gefunden. Sie vermuten, dass bislang unbekannte Mikroorganismen darin lebten. Oder es immer noch tun.
Researchers from the University of Mainz discovered unusual, small tubes in marble and limestone in Namibian and other desert regions. They suspect these tubes, which are not geological in origin, were created by previously unknown microorganisms, though they have not yet found DNA or proteins to confirm living or extinct organisms.
