Microsoft seems to be testing a search carousel titles "interesting reads." This can show up for a super competitive keyword phrase, like [coffee], [beer], [wine] and so forth. I personally cannot replicate it but the box seems to show content from news sites or blogs.
Microsoft Bing is now testing displaying the estimated reading time for some of the search results. Within some search result snippets, Bing is adding "estimated reading time" under the snippet. This can be pulling from some structured data or Bing can be using other methods for this.
