Carve it in stone

Science archivists are trying to figure out ways to store data and keep it accessible, even for the really long term:

Earlier this year, researchers at Keio University, Sharp Corp. and Kyoto University in Japan unveiled a memory chip designed to last for centuries. In April, physicists at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory published the design of a digital device that could store data for a billion years, at least in theory.

I've written about similar topics a few times, for example here and here. About a decade ago, I reviewed Gregory Benford's excellent Deep Time: How Humanity Communicates Across Millennia for the now-defunct webzine IntellectualCapital. In a mild irony, my review is now effectively lost, though at one point an archive-savvy reader did find it through the Wayback Machine.
