Regarding information in an entangled system

I was reading a bit more about quantum entanglement, while thinking about my previous post and came across a quantum entanglement webpage that had this to say:

Q: Can we use entanglement for instantaneous communications?
No. Current theories suggest that the information passed between particles in an entangled system must remain a secret. However, experiments involving the decay of radioactive particles may hold promise for detecting when one half of an entangled pair has changed

But….the author also claims:

Unlike the static nature of the web pages presented here, quantum physics is ever changing. Physicists are confronted with problems that will take many iterations, many years, to solve. Scores of theories will be presented, some of them merely tweaking, while others radically alter, our perceptions of quantum nature.
