Hmmm, I *have* had this happen to me, but usually I've benefited because the reserach is automatically bumped up to the next level if I'm working on it at the moment. I can't say whether it preserves the number of research points you have accumulated for that project so far, because I've only come across it once or twice.

Sometimes I'll come across ruins and only realise ten turns later *what* exactly it has bumped up - sometimes it doesn't pick what's currently being researched (I usually have all the labs at work and make a whole bunch of discoveries in rapid succession). And sometimes you get more than one extra tech, I think. Depends how lucky you are.
