Google is testing new features for SERPs. This feature is under testing, this feature is not yet live on Google SERPs
I have not seen this feature on SERPs, I have seen this feature in the tweet by Glenn Gabe,
Glenn Gabe has seen these features on SERPs, so Glenn Gabe tweeted about these features, you can also see the screenshot which is captured by Glenn Gabe.
Google shows top stories in the context section, I see in the screenshot google is showing trending news in this section.
I think this feature can replace Top Stories because currently, the same features are available in Top Stories.
You can see the above screenshot, which is of the context section features that Google is testing, and the screenshot given below is of Top Stories, which is already live on Google SERPs.
Here is the Glenn Gabe tweet.
I’m seeing this too across some top newsy queries -> Google Tests A For Context Section in SERPs https://t.co/zItDc3jJc0 via @VorticonCmdr h/t @tldrMarketing pic.twitter.com/P6ALM99Aa2
