    Scientists Stored These Images in DNA—Then Flawlessly Retrieved Them

    Who needs memory cards when you have DNA? A team of scientists has been able to store images within the life-defining molecules then retrieve them perfectly.

    Researchers from the University of Washington have been working out how to take digital files and convert them into strings of DNA that can be easily read back. Luis Ceze, one of the researchers, explains in a press release:

    “Life has produced this fantastic molecule called DNA that efficiently stores all kinds of information about your genes and how a living system works — it’s very, very compact and very durable. We’re essentially repurposing it to store digital data — pictures, videos, documents — in a manageable way for hundreds or thousands of years.”

    To do it, they first have to convert ones and zeroes that make up a digital file using the four basic building blocks of DNA— adenine, guanine, cytosine and thymine. Sounds easy enough, but much of the researchers’ time has been spent working out how to squeeze as much data into as short a string as possible without any errors.

    That’s done using Huffman coding, a fairly normal approach for lossless data compression.
