A news readers or aggregators or feed reader as they are commonly called allow you to subscribe to a content producers RSS or Atom syndication feed. There are a number of desktop and web-based feed readers available. I have listed some common applications below to assist you in your search for an application that meets your needs. For those just starting out with RSS, I recommend using Google Reader or Bloglines. They are both free and web-based so you can use them from any of the campus computers or on your personal computer without having to worry about keeping your subscriptions synchronized.
