I get a lot of news from HackerNews, but that's not really world news as much as "internet news." (and even then, just one corner of the internet news.)
As for irl news, it's primarily on Twitter from some journalists who have political views related to mine (so enthusiastically anti-Trump). Also, you'd be surprised how much /r/vexillologycirclejerk kept up with the news cycle, and I hope /m/vcj does the same soon.
