Biological Data Storage

How cool is this? Using artificial DNA to store information in bacteria is just brilliant and potentially will lead to faster computer processors, and EMP-proof data storage for corporations. Someone's going to figure how to make a lot of money off of this.

For all the potential benefits, it does raise three questions:

(1) What exactly is "artificial DNA," and what are its other potentially malicious uses of which we should be wary?

(2) Can this data be written into creatures beyond bacteria? Will I eventually be able to use my dog as a backup storage device? How cool would that be?

(3) Will scientists be able to use this artifical DNA to modify humans? In what way will they choose/be able/forced to do so? How far away is this?

Anyway, just things to consider. Still doesnt' change the coolness factor.
