Data Storing Bacteria Could Last Millennia 252

Posted by samzenpus from the written-in-the-genes dept.
PetManimal writes "Computerworld has a story about a new technology developed by Keio University researchers that creates artificial bacterial DNA that can carry more than 100 bits of data within the genome sequence. The researchers claimed that they encoded "e= mc2 1905!" on the common soil bacteria, Bacillius subtilis. The bacteria-based data storage method has backup and long-term archival functionality." The researchers say "While the technology would most likely first be used to track medication, it could also be used to store text and images for many millennia, thwarting the longevity issues associated with today's disk and tape storage systems ... The artificial DNA that carries the data to be preserved makes multiple copies of the DNA and inserts the original as well as identical copies into the bacterial genome sequence. The multiple copies work as backup files to counteract natural degradation of the preserved data, according to the newswire. Bacteria have particularly compact DNA, which is passed down from generation to generation. The information stored in that DNA can also be passed on for long-term preservation of large data files."

Ocean Planets on the Brink of Detection 159

Posted by Zonk from the look-for-mon-cal-first dept.
ZonkerWilliam writes "It seems, at least theoretically, that there may be 'ocean planets' out there in the galaxy. If there are, we are closer than ever to detecting them. The formation of such planets is fairly likely, reports the PhysOrg article, despite the lack of an obvious example in our own solar system. We may have a former ocean planetoid in the neighborhood, orbiting the planet Jupiter: the moon Europa. These water worlds are the result of system formation castoffs, gas giant wannabes that never grew large enough. If any of these intriguing object exist nearby, the recently launched CoRoT satellite will be the device we use to see it. The article explains some of the science behind 'ocean worlds', as well as the new technology we'll use to find them."
