Researchers have developed a new type of photochromic glass that can store and rewrite data indefinitely. By embedding magnesium and terbium, they’ve created a material that changes colors under ...

For decades, researchers have been exploring how to store data in glass because of its potential to hold information for a long time—eons—without applying power. A special type of glass that changes ...

In the study, the researchers describe a new type of material that follows a special process called Self-Adaptive Photochromism, or SAP, to achieve the ability to blend in with its surroundings ...
