Twitter is reportedly testing a News Tab that makes it easier for users to browse news headlines.

The trial tab sits above the navigation bar in the Twitter app, and features a stream of headlines from Twitter-approved publishers. 

It's intended to help users keep across breaking news more rapidly, and appears to function like a souped-up version of the recently discontinued Discover tab.
