Nucleic acid engineering

Mindblowingly cool design of riboswitches, nucleic acid logic circuits, etc.

This page is obviously waaaay incomplete; I haven't even scratched the surface, really. It's strongest for logic gates and suchlike, and very weak on applications and on the chemical diversity of RNA. I haven't even gone near DNA nanotech. (go start a page!)

  • total synthesis of poliovirus
  • ethical implications of this? my grandparents were killed by polio. discuss: what is the justification for building this thing?
  • some discussion at FAS
  • more in this article in the Indian Journal of Medical Ethics
  • apparently it was funded by the military
  • Craig Venter: "I think it's inflammatory without scientific justification. To purposely make a synthetic human pathogen is irresponsible."
