Nice model showing the progression of information in a social learning environment.

Very cool application of augmented reality for learning the alphabet and reading.

In my experience, produced a usable, but not phenomenal app. But far easier than trying to learn Android programming.

University of Pennsylvania teaches their PR2 to be able to read in the wild.  Video shows the PR2 roaming the hallways reading from various items sitting around and signs on the wall.  

"A new study by MIT scientists pinpoints areas of the brain used exclusively for language (PDF), providing a partial answer to a longstanding debate in cognitive science. According to the study, there are parts of our brain dedicated to language and only language. After having their subjects perform the initial language task, which they call a 'functional localizer,' they had each one do a subset of seven other experiments: one on exact arithmetic, two on working memory, three on cognitive control, and one on music; since these are the functions 'most commonly argued to share neural machinery with language.' The authors say the results don't imply that every cognitive function has its own dedicated piece of cortex; after all, we're able to learn new skills, so there must be some parts of the brain that are both high-level and functionally flexible."

Before May 1st, not even the smartest of machine learning algorithms could have predicted Keith Urbahn's online relevancy score, or his potential to spark an incredibly viral information flow. While politicos "in the know" certainly knew him or of him, his previous interactions and size and nature of his social graph did little to reflect his potential to generate thousands of people's willingness to trust within a matter of minutes. While connections, authority, trust and persuasiveness play a key role in influencing others, they are only part of a complex set of dynamics that affect people's perception of a person, a piece of information or a product. Timing, initiating a network effect at the right time, and frankly, a dash of pure luck matter equally.
