Sampling DNA From a 1K-Year-Old…Manuscript

QT:{{”
Remarkably, the authors say they extracted all this DNA without destroying even a tiny piece of parchment. All they needed were the crumbs from rubbing the book with erasers, which conservationists routinely use to clean manuscripts. The authors report their findings in a preprint that has not yet been peer-reviewed, though they plan to submit it to a scientific journal.”

Very interesting discussion outside of science about the potential of storing large quantities of archival data on DNA. The statistic is that you can store a little more than 2 petabytes in a gram of DNA. This is actually cost effective relative to magnetic tape if one wants to do storage for >500 years. However one imagines that as the price of DNA sequencing and synthesis goes down this will become more favorable, perhaps being reasonable for archival storage in the ~50 year regimen. One of the issues with DNA storage, of course, is the lack of random access and the inability to rewrite over already stored media. But for long-term archival storage DNA is considerably more stable than the magnetic storage on tape or disk.
