DNA can store digital data such as visual and audio files

Artificial intelligence can read data stored in DNA strands within 10 minutes instead of the required days for previous methods, bringing DNA storage closer to practical use in computing.
“DNA can store large amounts of data in an extremely compact form and remain intact for thousands of years,” says Daniella Bar-Lev at the University of California, San Diego. “In addition, DNA is naturally replicable and offers a unique advantage for prolonged data protection.”
However, retrieving the information coded in DNA is a monumental challenge because the threads are mixed and wander together when stored. During the data coding process, individual threads are sometimes replicated imperfect and some fragments can be completely lost. As a result, reading data stored in DNA can look like the reconstruction of a book from a checkout daughter with shredded, writing error-ridden pages.
“Traditional methods struggle with this chaos and require treatment days,” says Bar-Lev. The new approach “Streamline this with AI trained to see patterns in noise,” she says.
Bar-Lev and her colleagues developed an AI-POWRED method called DNAforms that can quickly and accurately decode virgin DNA sequences. The system included a deep learning AI model trained to Remadtruct DNA sequences, a separate computer algorithm that identifies and corrects errors and a third decoing algorithm that converts Everhything back to digital data, while
In the experiment, DNAforms could read 100 megabytes DNA storage data almost 90 times faster than the next quick method developed with traditional, rules-based computer algorithms the better or comparable accuracy obtained. The decoded data included a colored image of test tubes, a 24-second audio clip of astronaut Neil Armstrong’s famous moon landing speech and written text on why DNA is a promising data storage medium.
The team plans to develop versions of DNAforms tailored to recent techniques, forced data to DNA, says Omer Sabary at Technion – Israel Institute of Technology.
“Of crucial importance, for the procedure is not dependent on specific [DNA] Synthesis or sequencing methods, it can be adapted to future, as-yy -unddéd technologies that can be commercially viable, ”he says.
