You have to turn on SM mode in order to access it. Turn on SM mode by bringing up the little tiny bar you started the game with and pressing Ctrl-S. Then re-open the research window. Below the list of available researches should be an Instant button. Click it, voila.
Edit: Forgot to mention, when you press Ctrl-S it'll ask for a password. If you didn't set one, you can just hit Enter and it'll turn it on, since nothing is the password.
