| | Muse: Data in Hiding |
 | | When Viviana Risca was a high school student in Port Washington, New York, she found a way to hide secret messages among DNA molecules. |
 | | Working with researchers at the Mount Sinai School of Medicine in New York City, Risca created a single strand of DNA made up of a sequence of bases corresponding to the letters of a message. |
 | | These are chemical units called bases, and there are only four of them: adenine, thymine, guanine, and cytosineabbreviated A, T, G, and C. Normally, sets of three bases specify part of a protein, the molecules that do most of the work in a living creature. |
