Right now it seems like there's no stopping the juggernaut that is research. Once somebody has something, BAM, they have it, and you are in for a world of hurt if you don't do something about it.
But what can you do?
I propose that for a technology to be available and active for a civilization, they should own the appropriate amount of research stations for that type. ie; if a civilization has 15 military stations and just researched Insurrection, if you blow up one of their stations they temporarily lose the effect. They won't have to re-research it; they'd just need to build a replacement station to get the ability back.
This effect incurs an "upkeep" cost for higher technologies: every slot used for a research station is a slot you can't use for economic gain. It adds another method of balance.
It also makes research stations prime targets for attack; take out a few military research stations and suddenly they can't manufacture any more Kodiaks.
Thoughts?
