Phys.org: Researchers created a way to store data in the form of DNA, which lasts for tens of thousands of years.
The new method, published today in the journal Nature, makes it possible to store at least 100 million hours of high-definition video in about a cup of DNA.
There is a lot of digital information in the world – about three zettabytes' worth (that's 3000 billion billion bytes) – and the constant influx of new digital content poses a real challenge for archivists. Hard disks are expensive and require a constant supply of electricity, while even the best 'no-power' archiving materials such as magnetic tape degrade within a decade. This is a growing problem in the life sciences, where massive volumes of data – including DNA sequences – make up the fabric of the scientific record.
