Wavii (currently in BETA) is a website that allows users to select news that is important to them and as news happens related to that topic it will appear in a "news" feed. If you are teaching current events, this would be a great software to use to follow what is going on with that topic. Any subject matter that is being taught can be added as a topic to your feed and then as news happens related to it, you can be updated on the topic. The main goal of Wavii to take Google searches and put them into a Facebook type feed of information and news. The only negative that I have found so far is that it requires a Facebook log-in to use the site. You cannot create an account separately.
You could follow any item of content you are teaching and get the latest news on those topics and then share those topics with your students. The focus in education today is on Rigor and Relevance. If you can find current news and information related to what you are teaching, it will help to make the topic relevant to students.
