Data stored in DNA of living organisms

Found this article about an experiment that some scientists did with data storage. Basically they stored data in the DNA of a particular form of bacteria and then read that data back out.
That isn't really anything new. People have written data into DNA and read it back out before. There was even a prototype computer a few years back that used DNA.
What's new about this experiment is that they stored the data in a living bacteria culture. Then they caused the bacteria to grow for 100 generations. Taking the youngest generation, they then extracted the data out of the DNA of that generation. So the data they introduced into the DNA of the original bacteria was inherited by its descendants and was able to be read back after 100 generations. That is a pretty significant accomplishment that could lead to living growing computers and storage systems.
