DNA is the building block of life, but in the future it may also be the standard repository for encyclopedias, music and other digital data. Scientists announced yesterday that they successfully converted 739 kilobytes of hard drive data in genetic code and then retrieved the content with 100 percent accuracy.
The researchers began with the computer files from some notable cultural highlights: an audio recording of MLK Jr.’s 1963 “I Have a Dream” speech, all 154 of Shakespeare’s sonnets, and, appropriately, a copy of Watson and Crick’s original research paper describing DNA’s double helix structure. On a hard drive, these files are stored as a series of zeros and ones. The researchers worked out a system to translate the binary code into one with four characters instead: A, C, G and T. They used this genetic code to synthesize actual strands of DNA with the content embedded in its very structure.
A geothermal plant in Iceland
Iceland’s gigantic energy reserves, generated from renewable sources like geothermal vents, are all dressed up with nowhere to go—it’s too expensive to get power from the chilly island to anywhere else. But transporting data to and from the island is a different story. Iceland is starting to attract companies that build giant server farms, lured by the cheap electricity and the possibility of being able to market “green” power.
