Two recent experiments from two different groups claim to have closed the detection loophole for photons:

http://arxiv.org/pdf/1212.0533v2.pdf
However, evaluation of the results reveal that they both deviate from the QM prediction in exactly the same way. One of the correlations is completely off. Those of you familiar with the recent thread where I discussed Bell's illusion, degrees of freedom and the confusion of counterfactual probabilities with actual probabilities will recognize it.
