In laboratories where the language of life is written in molecular loops, scientists have demonstrated that circular mRNA — genetic instruction stripped of its vulnerable endpoints — can coax cells into producing proteins at six times the rate of conventional methods. The finding arrives at a moment when biotechnology is searching for ways to make biological manufacturing faster, cheaper, and more precise. Like the difference between a sentence that trails off and one that circles back to reinforce itself, the closed loop of circular mRNA simply persists longer, speaking its instructions repea
