We've briefly seen search tool Powerset in action at SES just a month ago. They were acquired by Microsoft around that time and are already being integrated into search results. The Powerset blog explains some of the feature offerings: Freebase Answers, improved captions for Wikipedia results, and new related searches using the Factz engine.

The blog also shows a screenshot of a relevant search. Unfortunately, I can't reproduce it just yet.

From what I see so far, these new features look quite promising.
