Bio-engineers at Stanford University, have successfully “recombinase – mediated DNA inversion”; meaning they encoded, stored and erased digital information within living DNA cells.
The findings were published in the Proceedings of the National Academy of Sciences.
This research could be explained as a non-volatile memory – a computer terms that cites how information can be stored without consuming power.
They invented a device called the recombinase addressable data (RAD) module. The team used RAD to tweak a section of DNA located in microbes. They measured the microbes response to ultra-violet light. The microbes glowed either red or green, depending on how the section was influenced (or turned on or off).
Digital Information Can Be Written onto DNA.
