  "textContent": "Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s about durability. By engraving data into ultra-stable ceramic materials, the team has opened the door to storing information that could last for centuries or even millennia without needing power or maintenance.",
