Google has launched two experimental products it hopes will change the way users search for pictures and news.
A feature known as "similar images" uses a picture rather than text to find other matching images.
Timeline presents information already available in Google News but organised and displayed chronologically.
Alongside these features is a new version of Google Labs in which users can get a sneak peak on what its thousands of engineers are working on.
Amid past criticism that Google has wasted too much time and effort on projects that have little impact, the aim of the Labs upgrade is to let users get their hands on prototype products at an earlier stage and give their feedback on them.
