Make DNA a 'living hard disk'

It sounds like a science fiction movie, but it's real. US scientists have recently announced how to transform living cells into digital data storage devices, a form of 'living hard disk'.

After several tests, a team of Stanford University researchers finally found a way to repeat the process of encoding, storing and deleting digital information within the DNA.

Storing data inside the cell can be widely used for future research. "It's a process-study tool when you need to rediscover the history of the cell," said The Stanford Daily chief Jerome Bonnet.

Most questions in biology today are about cellular history, such as 'why does this cell turn into cancer cells?' "said Ton Subsoontorn, who also belongs to the research group.

According to experts, similar to a computer chip that stores data by flipping an electronic or magnetic piece in the direction of shutting or opening, the DNA system flips a piece of DNA to display an off / on bit.

Data storage on DNA can assist biological engineers, as they can use them to study cell behavior in a system.
