Facial profiling for the detection of mal-intent using thermal imaging – I've been out of the loop on how far image processing has come in detecting emotions. If you think a computer that recognises your face is uncanny, how about one that can tell how you're feeling better than a human?
Beauty in the Breakdown – Beautiful writing about a climber's addiction to 'benzo' pills, and the interplay between anxiety, obsession, and all kinds of addiction.
Quandl – It's not a new idea, but this is a good implementation of a search engine for time-series data sets.
