A screenshot of a search results header design Google is testing posted on Reddit.

Confirmed by Google, it is now testing a core search results user interface design.  With this test, it includes a rounded search bar at the top, a smaller Google logo.  A really noticeable attribute is the search bar header that sticks to the top as a user scrolls through the results.

Here is another screen shot from the Reddit thread:

At this point, I was unable to replicate this test myself.
