Scientists have invented a new method of storing data within the DNA
Technology of the future is not only a constant increase in the computing power of processors or the transition to quantum computers, but also in the evolution of data storage devices. Humanity generates a huge amount of information that has to be stored by conventional means - in the HDD- and SSD-drives. Periodically, scientists suggest alternative ways of storing information, some of whom are very unusual. For example, using DNA as a data storage device. Recently, researchers of the Institute of Technology Waterford was offered another way to translate this technology into practice.
Experts suggest that by 2025 humanity will generate an average of 160 zettabytes data annually. Today, this data volume is 16 zettabyte. One zettabytes - a 10 21 bytes of data, so now you can just about imagine the scale of the current situation. Existing storage methods are not only ineffective, but also require significant energy costs, as well as large spaces to accommodate the necessary iron. Irish researchers have suggested another way of storing data within the DNA. To date, several groups of scientists are trying to develop similar technology have methods, but experts from the Institute of Technology, Waterford approached the problem with the unusual side. They are used for archiving and data recording bacteria. This method allows you to save 1 zettabytes data only 1 gram of DNA.
"We see in the DNA of some sort of software to ensure the cells containing a code that completely describes its functionality. That is why we can safely assume that DNA can be used perfectly to hold our own data. Take the information in digital form, convert it into nucleotides and use them to store data "- reflects the project manager Dr. Balasubramaniam Sasitharan.
At the moment, this method is very expensive, but over time its value will drop to a reasonable bar. Once this has happened to us today with the usual hard disk drives or solid state drives data. Technology developed by scientists Irish uses plasmid (small DNA molecule that is physically separate from the chromosome and genomic capable of replicating autonomously) to encode and store data within the bacteria strain Novablue E. coli E Coli. The choice in favor of this strain was made largely due to the fact that he has a fixed position, provides reliable data retention. Data can be recovered using the process of conjugation and to carry from place to place mobile bacteria HB101 strain forces all of the same E. coli. Control over this process is carried out by scientists antibiotics tetracycline and streptomycin. This method is not only expensive, as we have noted above, but also quite slow. The current search for necessary data required for up to three days of real time. But scientists are sure that the process can be greatly accelerated, because today there are methods of recording data in the DNA in a matter of seconds.
