Google Labs released two new features: Google News Timeline that organizes many different types of search results on a zoomable, graphical timeline from a wide range of sources. You can search and browse results from Google News, photos from Hosted News partners, YouTube partner videos, Google News Archive Search, Google Book Search, and also add Blog Search results and sports scores, as well as information about books, music, movies, tv shows, video games, and even artists, to see how they’ve appeared over time.
To browse through time, you can specify a date in your search, drag the timeline of results, or set the time scale to days, weeks, months, years, or even decades.
Similar Images Search is a tool you can use to find just about any kind of image, that look like an existing result simply by clicking on a link. Using visual similarity, you don’t have to refine the text of your search, instead, you can just click on the link of an image you like. If you search for [jaguar], you can use the “Similar images” link to quickly narrow your search.
