Sound/acoustic research?

I would like to know what is the current research (completed or in progress) in sound & acoustics technology, I would like to be able to view the list of papers/PH.D theses or research papers (those that are publicly viewable) and related products emailed to me. Where can I find? I am aware of northernlight but that is not what I want, I want something like the Nybbles weekly newsletter (Yahoogroups) that covers specifically my chosen field. I also want to know, I have some mp3s I want a software that "isolates" specific rhytm/beat tracks and then applies the same onto other songs (the same beat inserted into the appropriate points)
