Random thoughts about this article:
- "almost incorruptible" means "corruptible"
- How, exactly, did they come up with the number "one billion years" for
life of the data?
- Wouldn't something that small be really easily lost? Think looking
under your couch cushions for a terabyte of your data.
- What hardware and software enters, reads, edits, the data?
- Shouldn't "nanotechnology" have been one of the tags for the article?

Subject: [RM] Scientists invent memory storage good for a billion years
"Scientists are reporting successful tests of a new memory device that
could allow terabytes of data to be stored without corruption for
millions of years.
The device is an iron nanoparticle, 1/50,000 the width of a human hair,
enclosed in a hollow carbon nanotube.
The iron can be shuttled back and forth within the tube as an effective
way to store data.
The team says it is achievable to build storage devices capable of
carrying a terabyte of information per square inch, making it more
effective than current techniques.
However, the data will also be almost incorruptible and should remain
available for a billion years or more.
Current memory technologies are nowhere near as long lasting.
Conventional flash memory usually fails after around three to five
years.
As an example Alex Zettl, one of the team behind the invention, notes
that the Doomsday Book written on vellum has so far lasted over 900
years, whereas the digital version of the book, encoded in 1986, failed
in less than 20 years.
Details of the device will be published in scientific journal Nano
Letters later this month."
