Forget saving files to flash drives and cloud servers. Now, digital information can be stored in the DNA of living organisms, thanks to a breakthrough discovery by researchers at Stanford University in California.

A trio of scientists successfully demonstrated the ability to flip the direction of DNA molecules in sample E.coli bacteria in two directions, mimicking the “1s” and “0s” of binary code, which is at the root of all modern computer calculations.

“Essentially, if the DNA section points in one direction, it’s a zero. If it points the other way, it’s a one,” said Pakpoom Subsoontorn, a bioengineering graduate student at Stanford involved in the research, in an article on the Stanford School of Medicine website
