“We could put the whole world’s knowledge in 4 grams of DNA”

While not the first project to demonstrate the potential of DNA storage, Church’s team married next-generation sequencing technology with a novel strategy to encode 1,000 times the largest amount of data previously stored in DNA.

The researchers used binary code to preserve the text, images and formatting of the book at a density of 5.5 petabits (1 million gigabits) per cubic millimeter. “The information density and scale compare favorably with other experimental storage methods from biology and physics,” said Sri Kosuri, a senior scientist at the Wyss Institute and senior author on the paper. The team also included Yuan Gao, a former Wyss postdoc who is now an associate professor of biomedical engineering at Johns Hopkins University.

And where some experimental media — like quantum holography — require incredibly cold temperatures and tremendous energy, DNA is stable at room temperature. “You can drop it wherever you want, in the desert or your backyard, and it will be there 400,000 years later,” Church said.
