Scientists make DNA a “live hard disk†just like the plot in the movie “Defending Secrets†(datasheet)
International online specials: The idea of ​​storing data in living cells in many sci-fi plots has now become a reality. According to a report in the British "Daily Mail" on May 23rd, scientists at Stanford University in the United States have found a way to turn DNA into a "live hard disk" that can freely store or delete data in living cell DNA.
Stanford University scholar Jerome Bonnet said: "After more than 750 attempts over three years, we succeeded in finding a way to repeatedly encode, store, and delete data in living cell DNA. "This information will be stored as a DNA code, and it can be arbitrarily rewritten or deleted, so it can be used to study the problem of cell aging, and it can even be "turned off" before the cells become cancerous.
Cells are like a microcomputer in the human body and are very important to computer science and medicine. In a sense, the study of Bonnet et al. is equivalent to inventing a biological binary. Bonnet's colleague Drew Endy said: "Programmable data is stored in living cell DNA. This technology will increasingly become a powerful tool for studying cancer, aging, tissue development, and the natural environment. Etc." (Yang Liu)
