DNA can be found in nearly every cell of every living thing. The molecule is a chemical blueprint that effectively instructs cells on how to work. If holding the ?blueprint of life? isn't impressive enough, consider this: Scientists have now shown that DNA also offers a good way to store data.

Spoiler alert: For their new device, the researchers didn?t use DNA from a living organism. Instead they created a synthetic, or lab-built, mimic of DNA.
