An electron microscope view of phages duplicated inside bacterial cells that possess the immune system discovered in the new study. This immune system attaches a ubiquitin-like protein (marked by black dots and white arrows) to the tails of these phages, preventing them from infecting other bacterial cells

A bacterial immune system that alters the tails of phages might help clarify an immunity mechanism in humans


A newly discovered immune strategy protects bacteria and more advanced species, from corals to bees

Tree roots recruit beneficial bacteria during drought. Fluorescence and bright-field imaging reveals that during drought (left) a tree root is more densely colonized by two beneficial bacteria (green and red) than after irrigation (right)
