The Google news team has improved the "clusters" in their search results. Clusters are similar news stories that are grouped together. Previously, clusters were formed for 3 days, and then the individual news stories were kicked out the house to make it on their own.
Now, those clusters will exist for the full 30 day indexing of the news stories.
Writing on the Google News Blog, Lucian Cionca commented on how this change affects the big picture for Google News: "I think this brings us a step closer to our goal of making news universally accessible from as many sources, perspectives and languages as the world can offer."
