The field of biological computing has taken a significant step forward with the recent creation of a DNA-based computer that can solve logic problems such as chess and sudoku. This innovative device, described in a study published in Nature Nanotechnology, harnesses the unique capabilities of DNA molecules, opening up new frontiers in the way we think about computing and information storage. Unlike traditional silicon computers, this biological computer can store data at incredible densities, reaching up to 1,000 terabytes per cubic centimeter, demonstrating the extraordinary storage capacity of genetic sequences.

One of the main challenges in DNA computing has always been the fragility of the stored data. During the processing, in fact, the files themselves are often destroyed. The researchers addressed this difficulty by using an enzyme to transcribe DNA into RNA, generating a copy of the data that allows it to be used without compromising the original. Thanks to this innovation, the scientists were able to solve simplified versions of chess and sudoku on a 3×3 grid, revealing the potential of DNA as a new medium for computing and allowing processing times to be cut exponentially.
Furthermore, the DNA computer’s ability to maintain and access data without loss of information is a crucial advantage. Researchers have demonstrated that the system can maintain JPEG images, accessing the files repeatedly without compromising the integrity of the information. This long-term stability property seals the importance of this device not only for computation but also for advanced digital storage. The ability to manage and retrieve data securely opens up new possibilities for practical applications, from large-data storage systems to biomechanics and beyond.

Finally, as researchers continue to refine the capabilities of this biological computer, they are also working on systems that will mimic the cognitive functions of the human brain. The idea of building a PC that mimics the functioning of the human brain represents a fundamental challenge in the field of artificial intelligence and offers intriguing ideas for future developments. In short, the DNA computer represents not only a technological advance, but a paradigm shift in the way we interact with data and think about computation, suggesting a future full of possibilities and innovation.
