Google is changing its search results page to look more like the Google Mobile. You will notice that the “search tools” have now been moved to the top left side of the results and things like “images” are now over in the right hand column. Depending on the search you will also find in the right hand column “maps”, “people also search for” and “latest posts on Google+”. This column is being labeled currently as the Feedback / More info section.
You can get more details on Inside Search – The official Google Search blog.
