Deep within every living cell, the molecular machinery of life carries a hidden limitation: the ribosomes that build our proteins routinely stumble when constructing the membrane-bound molecules that govern what passes in and out of cells. Researchers in Cologne have illuminated this ancient cellular struggle, revealing that a built-in quality control system destroys incomplete proteins to protect the cell — yet in doing so, may quietly diminish the supply of proteins whose absence already causes suffering. For those living with cystic fibrosis, this discovery reframes a familiar disease as so
