There are some plugins which do create these kind of posts automatically based on keywords. But for what I know and feel it's much better nowadays to spend 20 minutes and do it manually, plus adding comments and tips, in short, provide curation to the post.
For automated plugins in Wordpress you can simply enter "automated google news plugin" or else I would say. Look also for "goolge news" within the plugin search inside Worpdress
You can also create content from a RSS feed in a widget or in the footer of your Wordpress theme and so get updated news around that topic. Just copy any available RSS feed link about a subject (found on relevant websites and pages), use a RSS feed plugin if the WP theme you use does not have it, and paste that link.
