Link to paper: I guess the reason this shows up on slashdot is that it was on MITnews (and of course the work was done at MIT). It is nothing really groundbreaking (or novel for that matter). They use Compressive Sensing where they assume that the different scan types (T1, T2,etc) have a similar structure (same sparsity profile, enforced through shared precision hyperparameters in a Bayesian formulation).

Comment Unison (Score 3, Informative) 482

It is quite fast, my synchronized folder is currently ~7GB and it takes maybe 10s to check for changes (not sure how Unison manages to do this).
