thousands of years – by putting it on microscopic strands of DNA.
At a meeting of the American Chemical Society, a team of researchers reported they’ve been able to demonstrate encapsulating information on DNA that endured the equivalent of 2,000 years in storage with no errors when the data was retrieved and decoded.
They simulated the passage of centuries by embedding the data-carrying DNA in spheres of silica and heating them to 160 degrees Fahrenheit, leaving them at that temperature for a week.
That equates to around two millennia at 50 degrees, the researchers say, yet when the data was retrieved and decoded it was complete and error-free.
The scientists at the Swiss Federal Institute of Technology in Zurich say they’ve successfully encoded images, video and audio with the DNA technique, and that the long-term storage technique could accommodate anything that can be recorded as digital binary code.
As digital technology creates ever more massive amounts of data, some way of storing that in extremely compact form and for a long time becomes desirable, they say.
