In 1974 astronomers at the Arecibo observatory in Puerto Rico beamed a radio message toward the Great Cluster in the constellation of Hercules. The message consists of 1679 binary digits, i.e. a series of 1's and 0's. A receiving intelligence is to arrange these 1's and 0's into a matrix of 23 columns by 73 rows and then translate the 1's and 0’s into contrasting dark and light squares. The resulting digital picture is then to be interpreted for meaning. Our astronomers hope that if the message is received by non-earthly intelligences those folks will be able to decipher it and conclude that "intelligent life" exists on the third planet of the star from which the radio beam emanated. Consciously or not our astronomers selected numbers to define the size of the information matrix which will reassure any receivers of the message, who are familiar with Kabbalah’s mathematical methodology known as gematria, that we are indeed "intelligent life", since 73 is the numerical value of the Hebrew word chokmah - חכמה meaning "intelligent" (or “wisdom”, or “science”) and 23 is the numerical value of the Hebrew word chyah - חיה meaning "to live, be alive, exist". (Definitions from Ben-Yehuda’s Hebrew-English Dictionary)
Perhaps this technique, applied to the human genome, would be worth examining.
Here is a site that plays with the idea of messages in DNA.
