In a groundbreaking development, scientists unlock the potential of DNA to handle data storage and computing, heralding a new era in technology.
For the first time, researchers from North Carolina State University and Johns Hopkins University have unveiled a cutting-edge technology that combines data storage and computing functions using DNA. This innovative approach marks a significant leap forward, allowing DNA to not only store data but also process it—an achievement that conventional electronics have mastered, but DNA-based systems had yet to fully achieve. The breakthrough opens up new possibilities for future computing, where biological molecules could rival silicon chips.
The study, titled “A Primordial DNA Store and Compute Engine,” published in Nature Nanotechnology, reveals the capability of this DNA-based technology to repeatedly perform essential computing tasks. These include storing, retrieving, erasing, rewriting, and even computing data—all within a single system. Previous DNA technologies could manage some of these functions, but this is the first to handle them all seamlessly.
Albert Keung, the project leader and co-corresponding author, emphasized the importance of this innovation. "In conventional computing, data storage and processing are separate, but they’re compatible," explained Keung, an associate professor at NC State. "DNA computing faced the challenge of integrating these functions while using nucleic acids for storage."
The newly developed "primordial DNA store and compute engine" has demonstrated its prowess by solving complex puzzles like sudoku and chess problems. The researchers also found that the DNA-based system could securely store data for thousands of years without degradation, making it a potential game-changer in long-term data storage.
