Scientists store data in molecules smaller than DNA

  1. It’s been years since scientists demonstrated the ability to store data on DNA but as it turns out, deoxyribonucleic acid isn’t the only molecule capable of replacing hard drives.

    Jacob Rosenstein and his colleagues at Brown University have managed to store data on an array of molecules including those containing sugars and amino acids.

    The presence or absence of specific metabolites in their mixtures represented the 0s and 1s needed to encode digital information. Using a mass spectrometer, they were then able to analyze the mixtures at an accuracy rate of around 99 percent.

    Rosenstein and crew claim the approach could make data less susceptible to hackers. And in harsh environments that undergo extreme temperature, pressure or mechanical force, molecular memory could even be more stable than electronic memory.

    Additional testing and optimizations are needed before the approach becomes commercially viable. Today, molecular memory is slow compared with what is possible via electronic computers although it does have lower latency than DNA storage. DNA, Rosenstein conceded, is still superior for encoding large data sets.

    This is amazing. In 20 years, I want entire Netflix backed up in my blood stream.

    " to store data on an array of molecules including those containing sugars and amino acids."

    Is that a cookie in your pocket or a hard drive??

    Saw info about this some 10-15 years ago. I'm sure it's the future, but the question, as always, is when?

    Still far from storing the images into quantum states.
