Yesterday afternoon I posted an article about synthetic nucleic acids and processing of arbitrary information from the field of synthetic biology. To recap briefly, by adding synthetic components to bioengineered bacteria researchers have been able to represent and manipulate information with XNA, a variant of DNA which involves synthetic compounds in addition to the four naturally found in DNA. One of the commenters on that post is working somewhere in that field and mentioned a few of the things that can be done with those custom-designed nucleic acids. This reminded me of another article I've had in my to-write queue …
Windows XP, let me be clear. And they won't let you download it unless you're using IE on a known valid (by WGA) copy of Windows, but there are ways around that (thanks, cow-orker!).
