There are many ways to store data—digitally, on a hard disk, or using analog storage technology, for example as a hologram. In most cases, it is technically quite complicated to create a hologram: ...

Molecules like DNA are capable of storing large amounts of data without requiring an energy source, but accessing this molecular data is expensive and time consuming. Researchers have now developed an ...

Researchers created a proof-of-concept DNA origami device that encodes messages as nano-Morse patterns and conceals them inside tubular nanostructures. The system combines symmetric encryption, ...

Inspired by naturally occurring air bubbles in glaciers, researchers have developed a method to encode messages in ice. Published in Cell Reports Physical Science, the paper explains how the team ...

Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to ...
