DailyDirt: Keeping Information For A Really, Really, Really Long Time
from the urls-we-dig-up dept
The problem of storing digital data usually involves transferring data from an older format to a newer one — with the hopes that the newer one won’t be replaced as quickly as the older format it just replaced. Maybe some archivists out there like to go through this periodic technology shift and verify that the data we’ve stored is still readable, but wouldn’t it be nice if there was a “store it and forget it” format?
- A single gram of DNA can store up to 455 exabytes of data, and roughly four grams of DNA could store all of the world’s collected information. It’s not cheap to store arbitrary data on DNA yet, but the costs are coming down. [url]
- Stored data on DNA encased in glass at freezing temperatures could survive for a couple million years. The DNA of a woolly mammoth in Siberia was preserved for 40,000 in a tundra, so it’s not unthinkable that we might want to keep a few backups of our data on ice. [url]
- Making large DNA crystals with precisely-controlled structures is something that can be done with a “DNA-brick self-assembly” method. Being able to do this could help fabricate all kinds of nanoscale designs and create a manufacturing process for complex, artificial DNA structures. [url]
