Well, I went to a lecture by one of the most prominent scientists here in Brazil, where he explicitly said that the answer to your question is NO. Research as it stands today exists to feed the system. According to him, you:
* Publish, so you can get grants
* Use that grant so you can publish more
* Get more grants;
* Get tenure somewhere in the middle.
I have to confess I was very disgusted by him saying that in front of such a large audience of scientists and graduate students.
