This is why I enjoy going to random talks advertised by your department/other departments - you are exposed to ideas outside of your specialization, you have a chance to meet other researchers etc. Sadly most universities (in my experience) don't have a central newsletter for these, usually only for generic talks that are more designed around a "science is interesting!" theme for the public layman.
Some people at the the University of Queensland used to run the COMBIO seminars, small seminars with sponsored pizza & beers afterwards. Two scientists would present anything related to computational biology, didn't matter what exactly, or what their specialization was. These were a great starting point for networking.
If you're working at a university and would like to see something similar I strongly suggest you set it up yourself, it's a lot of unpaid work but "if you build it, they will come".
