A few hundred feet inside a permafrost-encrusted mountain below the Arctic circle sits the seed bank that could be humanity's last hope during a global food crisis. This month, scientists suggested that this unassuming vault is the ideal space for preserving the world's data on DNA.
This is the Svalbard Global Seed Vault, a bunker on the Arctic island of Svalbard, which for the past seven years has amassed almost a half million seed samples from all over the world. The idea is to use the naturally freezing, isolated environment of the far north to preserve the world's plant life and agricultural diversity—which, of course, is under threat by climate change and disaster. If a food crisis occurs, the vault could provide the seeds that repopulate parts of the world.
But it could potentially preserve much more than seeds. A study in the German chemistry journal Angewandte Chemie this month details the quest to find out how long data stored on DNA could be preserved, and also suggests the vault as the ideal storage location.
The Guardian reports that the Svalbard Global Seed Vault, a seed bank near Longyearbyen on the Norwegian island of Spitsbergen, has flooded due to "melting and heavy rain." The seeds remain safe, according to the article.

Microsoft is purchasing synthesized strands of DNA to test DNA data storage:
Microsoft is buying ten million strands of DNA from biology startup Twist Bioscience to investigate the use of genetic material to store data.
The data density of DNA is orders of magnitude higher than conventional storage systems, with 1 gram of DNA able to represent close to 1 billion terabytes (1 zettabyte) of data. DNA is also remarkably robust; DNA fragments thousands of years old have been successfully sequenced. These properties make it an intriguing option for long-term data archiving. Binary data has already been successfully stored as DNA base pairs, with estimates in 2013 suggesting that it would be economically viable for storage of 500 years or more.
At a future price of 2 cents per base pair, or 1 cent per bit (ignoring the need for error correction), a terabyte would cost $80 billion (and weigh a nanogram). Once synthesized, copying it would be as cheap as using a PCR machine.
