> Edit: Don't know why I'm getting voted down. The OP was questioning whether there's a research group at Google, in the comment section for an article by somebody who's worked in that department for ten years. If that's not a definitive answer to the question, I don't really know what the OP is expecting.

It sounded like an innocent question to me and it was one I also had. While there is a research site it still wasn't entirely obvious to me how it worked. You're probably getting downvoted for the lying bit and being condescending.
