Researchers from Heinrich Heine University Düsseldorf and Kiel University discovered that the starlet sea anemone, Nematostella vectensis, uses specialized mobile cell structures called nematosomes to selectively identify and destroy harmful bacteria while preserving beneficial ones. This challenges the long-held assumption that targeted immune discrimination requires the complex adaptive immune system of vertebrates, pushing back the evolutionary timeline for such capabilities by hundreds of millions of years.
