MSR Asia is based in Beijing and is one of the fastest growing research outfits in the world. They're slowly showing up all over the place in the CS world, and this is just one of the examples.
Consider Microsoft Academic Search. It BLOWS AWAY Google Scholar, Citeseer etc. in terms of features. Once they attain coverage parity, there is reason to use anything else.
Academic Search, Trinity, and similar projects out of MSR Asia seem to be directly having impact in Bing. In a matter of a short few years, you're looking at a barebones search engine (Live.com) building an R&D infrastructure, with prototypes, and production modules feeding into what is now a pretty rocking search engine. [Example of Academic search integration with Bing: http://www.bing.com/search?q=donald+knuth , scroll to bottom -- page also shows Freebase integration in middle]
Ironically, Microsoft is playing David in the David vs Goliath story here, and the passion is showing in terms of the ecosystem of computing projects and products that are making it into Bing.
If you want to look outside of Bing, consider the Kinect effort. Did you know that the _hardware_ ships with mathemetical models built at MSR, trained using Dryad? (Dryad is an MapReduce competitor out of MSR) The training is the "secret sauce" and why you don't have to spend days calibrating the Kinect.
None of this is privileged information -- you just have to follow the hyperlinks :) The open source world is built on collaboration and sharing, and hence the "story" is the backbone of most work. But that doesn't mean other people don't have stories and passion!
