The smallest QR code in the world is so very tiny that your phone would need an electron microscope to scan it. The matrix ...

Working with data storage technology company Cerbyte, Mayrhofer and colleagues were especially interested in identifying a material durable enough to use repeatedly at an atomic level. The answer came ...

Burger King is testing AI-powered headsets that can recite recipes, alert managers when inventories are low and even track ...

A 1.98-square-micrometer QR code, etched into ceramic thin film and verified by Guinness, showcases a new approach to ultra-dense, long-term data storage.

You might not think of a CAPTCHA check as a cybercrime lure, but if you fall prey to one, you may become infected with malware. Learn how to spot them with our guide.

QR codes may look like random checkerboards, but they rely on mathematics powerful enough to decode signals from deep space. Built on Reed–Solomon error correction, a QR code can still function even ...

A team of researchers at TU Wien recently announced that they have "etched" the smallest QR code ever on a ceramic film. Covering an area of ...

Researchers at TU Wien in Vienna have created a QR code so small it can only be read with an electron microscope. The code measures roughly 1.98 square micrometers, with individual pixels about 49 ...

The ceramic thin film technology behind the record could store over 2 terabytes on a single A4 sheet and preserve data for millennia without any energy input.

Order doesn’t always form perfectly—and those imperfections can be surprisingly powerful. In materials like liquid crystals, tiny “defects” emerge when symmetry breaks, shaping everything from cosmic ...
