DNA

    What does the D in DNA stand for? For biologists, it’s ‘deoxyribo’ (you knew that, right?), but for computer scientists, increasingly it means ‘data’. Big Tech – Google, Amazon, Microsoft and Facebook – already store 1,200 petabytes of data between them. That is 1.2 billion gigabytes. And server farms are set to emit 3.2% of global carbon and consume a fifth of global electricity by 2025. But DNA packs biodata so tightly that it could store the Internet in a shoebox. So tech companies are developing ways to convert digital data into synthetic DNA built from the four bases of genetic code.
