The study said the bacteria can become a ” hard ” information passed from generation to generation backup

[ Abstract] At present, Harvard University scientists latest research shows that bacteria can live as “hard”, the backup generations pass some information, even if some bacterial death.

American scientists will be able to live bacterium transformed into “hard” copy backup information content.

Tencent science News website reported, according to Mother Nature, the scientists added to the bacterial DNA code that can be inherited to the next generation, DNA genetic information stored in a manner similar to a computer hard disk to store data.
Currently, scientists have found a way to live bacteria into the hard disk!

Harvard geneticist Seth – Shipman (Seth Shipman) and Jeff – Nivala (Jeff Nivala) led a research team devised a way, the bacteria can replicate computer code, this information is passed from generation to generation,
ensuring that information can be “backed up”, even if the individual bacterial death.

So far, this technology can be approximately 100 bytes of data uploaded to the bacteria, which is enough to store in a cell a short letter or poem.
When the process becomes more accurate, it will be possible to enter more text encoding bacterial body, perhaps the next day, parasites in the human bacteria can be used as a library that allows human beings to download content.
Although this is the distant future can be achieved, but it is very interesting.
This technology is based on

present in many bacteria immune response handling, operation of the system is actually relatively simple, when bacteria encounter the threat of viruses, can instinctively cutting off part of a virus attack DNA, it is mixed to a particular gene region.
After the bacteria using viral DNA to identify the next part of the virus that may be encountered, and the rapid formation of the defense system, copy the immune partially into the genetic code, the bacteria can pass information to offspring.

order for bacteria to replicate computer code, researchers are only the computer code as a virus DNA treated after bacteria are able to work, cut and paste the relevant information to specific gene regions.
However, this technology currently there are still many problems, such as: not all bacteria can cut full content, only part of the information can be copied, but if the code is introduced into the bacterial population will be able to easily obtain complete information

store information storage capacity depends on the bacteria, the researchers used in the experiments of E. coli, the bacteria can only store about 100 valid bytes, but other bacteria, for example: solfataricus can store thousands of bytes, by using
synthesis biological science engineering process, the bacteria can exponentially increase the information storage capacity, making the technology more effective implementation.
