Towards Self-replicating Machines

In recent decades, there have been several attempts to supplement traditional electronic storage media. 3D codes with color as the third dimension are an interesting approach. They can be applied to paper or film, for example. Another approach has now been presented by researchers from Switzerland and Israel. They are able to generate artificial DNA and place it in any object. From the Abstract: “We devised a ‘DNA-of-things’ (DoT) storage architecture to produce materials with immutable memory. In a DoT framework, DNA molecules record the data, and these molecules are then encapsulated in nanometer silica beads, which are fused into various materials that are used to print or cast objects in any shape. First, we applied DoT to three-dimensionally print a Stanford Bunny that contained a 45 kB digital DNA blueprint for its synthesis. We synthesized five generations of the bunny, each from the memory of the previous generation without additional DNA synthesis or degradation of information. … DoT could be applied to store electronic health records in medical implants, to hide data in everyday objects (steganography) and to manufacture objects containing their own blueprint. It may also facilitate the development of self-replicating machines.” (Abstract) The approach could also be interesting for robots. They could, for example, reproduce themselves on Mars.
