NEW DEVICE TO STORE DIGITAL INFORMATION AS DNA


The data stored in a warehouse-sized data centre today would fit into ‘a space roughly the size of a few board game dice’
Tech major Microsoft has developed an end-to-end automated DNA storage device that can translate digital information into DNA and back to bits, the company said recently.
The automated system to store and retrieve data in manufactured DNA is a key step in moving the technology out of the research lab and into commercial data centres.
The novel system, developed in partnership with the University of Washington, translated ‘Hello’ into DNA and converted it back to digital data in just 21 hours, reported the paper published in Nature Scientific Reports journal.
“Our goal is to put a system into production that, to the end user, looks like any other cloud storage service — bits are sent to a data centre and stored there and then they just appear when the customer wants them,” said Karin Strauss, principal researcher at Microsoft. “To do that, we needed to prove this is practical from an automation perspective,” Strauss said.
The system has so far stored one gigabyte of data in DNA, which includes cat photographs, great literary works, pop videos as well as archival recordings in DNA, which could be retrieved without errors, the researchers said.
The automated DNA data storage system uses software that converts the ones and zeros of digital data into the As, Ts, Cs and Gs that make up the building blocks of DNA.
When the system needs to retrieve the information, it adds other chemicals to prepare the DNA and uses microfluidic pumps to push the liquids into other parts of the system that ‘read’ the DNA sequences and convert it back to information that a computer can understand.
Information is stored in synthetic DNA molecules created in a lab, not DNA from humans or other living things, and can be encrypted before it is sent to the system.
