This idea has been implemented before, quite a long time ago actually, it didn't last long. The thing about the news is that people are always opinionated and there will end up being a large debate even on a thread like that is being proposed now. People have opinions and like myself, we want to share those opinions. If someone posts a lot of news articles in one thread, it would defeat the purpose of a section like this, people will want to post their opinions and the thread will turn into a clusterfuck, the other downside is that people will double post the news.
People double post threads all the time, it won't change even with an official news thread, they'll want to all post in a thread that has many articles.
