At Heinrich Heine University Düsseldorf, researchers have discovered that bacteria navigate the delicate task of embedding proteins into their membranes through the same pathway once thought exclusive to more complex, nucleated life. The finding — that a so-called 'back-of-Sec' route is shared across the tree of life — suggests this molecular solution was forged early in evolution and preserved with remarkable fidelity across billions of years. In answering a seemingly narrow question about bacterial plumbing, science has glimpsed something older and more universal: a common inheritance writte
