Thought people would be interested in this recently published paper:
http://advances.sciencemag.org/content/2/2/e1501466
It came up on my Facebook feed because I am friends with one of the authors.

I'm a bit suspicious, due to the use of weak measurements. Thoughts on this experiment? (The full text is available for free, from the link above.)

Weak measurement allows one to empirically determine a set of average trajectories for an ensemble of quantum particles. However, when two particles are entangled, the trajectories of the first particle can depend nonlocally on the position of the second particle. Moreover, the theory describing these trajectories, called Bohmian mechanics, predicts trajectories that were at first deemed “surreal” when the second particle is used to probe the position of the first particle. We entangle two photons and determine a set of Bohmian trajectories for one of them using weak measurements and postselection. We show that the trajectories seem surreal only if one ignores their manifest nonlocality.
