STRONGER - FASTER - BETTER AND TOTALLY SECURE : The greatest inventive bulwark  against corruption : 

Storing Information in Molecules for ''Millions of Years'' As data boom continues to boom, more and more information gets filed in less and less space.

Even the cloud - whose name promises opaque, endless space - will eventually run out of space, can't thwart all hackers, and gobbles up energy.

Now, a new way to store information, could stably house data for millions of years, lives outside the hackable Internet, and once written, uses no energy.

All you need is a chemist, some cheap molecules, and your very, very precious information.

The Global Digital Archive is estimated to hit 44 trillion gigabytes by 2020 - 10 times that of 2013.  An image of a tsunami seems appropriate.

Oligopeptides also vary in mass, depending on their number and type of amino acids. Mixed together, they are distinguishable from one another, like letters in a alphabet soup.

But, but making words from the letters is a bit complicated   :
In a microwell - like a miniature version of whack-a-mole but with 384 mole holes - each well contains oligopeptides with varying masses.

Just as ink is absorbed on a page, the oligopeptide mixtures, are then assembled on a metal surface where they are stored.

If the team wants to read back what they ''wrote,'' they take a look at one of the wells through a mass spectrometer - which sorts the molecules by mass.

This tells them which oligopeptides are present or absent. Their mass gives them away.

Then, to translate the jumble of molecules into letters and words, they borrowed the binary code. An ''M,'' for example, uses four or eight possible oligopeptides, each with a different mass.

The four floating in the well receive a ''1, '' while the missing four receive a ''0''. The molecular binary code points to a corresponding letter or, if the information is an image, a corresponding pixel.

With this method, a mixture of eight oligopeptides can store one byte of information; 32 can store four bytes; and more could store even more. 
So far, Cafferty and his team ''wrote,'' stored, and ''read'' physicist Richard Feynnman's famous lecture
''There is  plenty of room at  the bottom,'' a photo of Claude Shannon [known as the father of information theory], and Hokusai's woodblock painting The Great Wave off Kanagawa.

Since the global digital archive is estimated to hit  44 trillion gigabytes by 2020 [ten times that of 2013], an image of a tsunami seems appropriate.

Right now, the team can retrieve those their stored masterpieces with 99.9% accuracy.

Their ''writing'' averages 8 bits per second and ''reading'' averages 20 bits per second.

Although their ''writing'' speed far outpaces writing with synthetic DNA, reading could be both quicker and cheaper with the macromolecule.

But, with faster technology, the team's speeds are sure to increase. An inkjet printer, for example, could generate drops at rates 1,000 per second and cram more information into smaller areas.

And, improved mass spectrometers could taken in even more information at a time.
