Researchers have developed a minuscule QR code, so small it requires an electron microscope for viewing, making it smaller than most bacteria and a new world record. This breakthrough extends beyond mere size; its true significance lies in its incredible durability. By imprinting data onto highly stable ceramic materials, the team has paved the way for information storage that could endure for hundreds to thousands of years, entirely free from power requirements or ongoing upkeep.
