After changing the snippets for Twitter accounts, Google now displays the latest headlines in the snippets for news sites. Search for [washington post], [nytimes], [le monde], [gazzetta dello sport] and you'll find the latest news from the snippets.
Probably the best way to try the new feature is to search for [news] and check the new snippets.
It's likely that the headlines are obtained from Google News, but not all the sites included in Google News have the new snippets.
