No surprise here, Google Scholar has moved to the UI design seen on other Google search interfaces.
From the Google Scholar Blog:
The new modern look brings you improved aesthetics and easier access to frequently used search features. You can now search for recent papers with a single click in the sidebar. You can access advanced search features (for example: search by author) without leaving the search results page by clicking the arrow in the right of the search box.
We’ve also clarified the preferences, err, settings page by organizing it into sections, performed a minor facelift on pages that deal with configuration of email alerts, and next we’ll be working on updating the author profile pages and help pages.
If you’re not seeing the new look (yet) and want to begin using it click here.
If you’re seeing the new “modern” look and what the old look back (temporarily) click here.
