It's been more than a year since Google introduced expandable results into Google News, clustering related articles under a single headline and letting users expand the link to see more.

Today Google said it will roll out expandable results, along with a handful of other user interface improvements, into its search results over the next few days. Among the changes: Searches will now reveal a multimedia bar showing related photos and videos.

The changes will be evident to anyone searching within Google itself or within the Google News site.

Google is also updating the layout slightly to put the article image on the left and the source information underneath the article links.
