What I'd like to see is some kind of "ongoing" or dossier for news. So when an errata or new development happen, even years later, you get a notification and can update your knowledge.

Specifically for things like "future miracle cure for X" or trials. Like "what happened with the Panama Papers"? Then you'd get a full dossier of articles, links, comments etc. It may require some standardized way to link news article together.
