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 different wavelengths of light, allowing for high-density, long-term storage without power. This breakthrough could revolutionize data preservation.Exploring the Potential of Glass for Data StorageFor years, scientists have explored the potential of glass as a long-term data storage medium, drawn to its ability to preserve information for eons without requiring power. One promising candidate is photochromic glass, a special type of glass that changes color when exposed to different wavelengths of light. Now,...
