William
Shakespeare, depicted in this 17th century painting, penned his sonnets on
parchment. Now his words have found a new home ... in twisting strands of DNA.

But the DNA was there, tiny specks at the bottom of the tubes. They sequenced the DNA, read the code, ran their cipher backwards.
And they ended up with a 100% accurate Shakespearean sonnet.
So long lives this and this gives life to thee.
All from the tiniest speck of DNA. They published their results in the journal "Nature," joining other groups who have experimented with DNA storage.
Goldman says the process would be easy to scale up. If you took everything human beings have ever written, an estimated 50 billion megabytes of text, and stored it in DNA, that DNA would still weigh less than a granola bar.
There's no problem with holding a lot of information in DNA. The problem is paying for doing that.
The process would cost more than $10,000 per megabyte.
It's an unthinkably large amount of money at the moment.
At the moment.
Goldman and other scientists who are dabbling in DNA storage know that DNA synthesis costs are dropping rapidly. In a decade or so, a DNA archive might be cheaper than a room full of hard drives.
