First, one talking about the transactional interpretation of quantum physics, which I've mentioned here before, and been wondering whether it's going anywhere. I haven't done much other than scan the paper (it's a heavy read, and I'll be skipping the maths), but it's worth looking at more carefully, I think.
Secondly, here's one talking about the enduring puzzle of the double slit experiment with the enticing title Can a Single Photon Modify Two Remote Realities Simultaneously? Here's the abstract:
The concept of wave-particle duality, which is a key element of quantum theory, has been remarkably found to manifest itself in several experimental realizations as in the famous double-slit experiment. In this speci?c case, a single particle seems to travel through two separated slits simultaneously. Nevertheless, it is never possible to measure it in both slits, which naturally appears as a manifestation of the collapse postulate. In this respect, one could as well ask if it is possible to "perceive" the presence of the particle at the two slits simultaneously, once its collapse could be avoided. In this article, we use the recently proposed entanglement mediation protocol to provide a positive answer to this question. It is shown that a photon which behaves like a wave, i.e., which seems to be present in two distant locations at the same time, can modify two existing physical realities in these locations. Calculations of the \weak trace" left by such photon also enforce the validity of the present argumentation.
Steve, the best advice I have read on QM ...

"Modern interpretations are more realist, but the conflict between them is such that any rational person who is not a highly trained expert in the field should simply tell the QM industry to go away and report back to the rest of the intellectual world when they have sorted it out."

Yeah I'm a hypocrite because I am currently reading Sean Carroll's tome on Time.
