Scientists have reported an unprecedented 3D-printed “rabbit” using a special material called “Dna of Everything”, according to a study published Monday in the British journal Nature Biotechnology. The material contains a rabbit “blueprint” used to synthesize DNA coding, after which the DNA contained in the original rabbit was decoded and steadily replicated five generations of rabbits.
With increasing global data volumes, traditional storage architectures, such as hard drives and tapes, are increasingly struggling to keep up with the need for data storage. As these devices reach storage limits, DNA is proposed as a long-term storage solution. Past research has highlighted the persistence of DNA and its ability to store vast amounts of information, and now researchers have found an unprecedented way to store it using its persistence.
Israeli computational geneticists Yanif Ellih and Robert Glass, among others, have developed a storage structure for “DNA of everything”, which can produce materials with constant memories. To test this method, they encoded the blueprint of the common computer graphics test model, the Stanford Rabbit, into a DNA-compatible format and stored it in a DNA molecule that encapsulates the DNA molecule in a silicon dioxide ball, which is embedded in biodegradable thermoplastic polyester. Finally, the “rabbit” was printed using the resulting thermoplastic polyester 3D.
The team then copied it using DNA stored in the rabbit: a small piece from a 3D-printed rabbit to decode the DNA molecules it contained. This creates five generations of “rabbits” without any loss of information, with the previous generation’s enlarged DNA encapsulated into the next generation;
In a second experiment, the researchers encoded a video of the Warsaw Ghetto archive into resin glass and used it to make ordinary glasses. A small piece of resin glass can restore the hidden information.
The team’s concept of “DNA of everything” hides information and can be used to make everyday items.
