A team of swiss engineers hope to employ DNA as a method to store more data. Today, our hard drives can store up to five terabytes of data, encoded with the zeros and ones of binary code. But if data were stored in DNA, the four chemical nucleotides (A, C, G, and T) could theoretically hold up to 300,000 terabytes. The researchers also wanted to see if the DNA would be able to retain information longer than a hard drive does now (which is about a few decades). They encoded DNA with 83 kilobytes of text written in the 13th and 10th centuries. They stored the DNA in silica spheres to protect it, and then warmed it to 160 degrees Fahrenheit for a week—the equivalent of keeping it at 50 degrees for 2,000 years. When the researchers decoded the DNA, they found no errors, indicating that the DNA held up well and the information they encoded stayed intact.
