How to Download New Articles From a List of Websites? Recommendations?

I've ran into several dead ends trying to come up with a result from a Google search. Essentially, I have a list of say 20 websites, all research institutes that occasionally update their websites/blogs with their latest findings.

I'm trying to either A - find a software that can check for new articles, then send me the title and link to the article, or B - write a script that check for new articles, then send me the title and link.

Any suggestions or software recommendations?
