After performing multiple tests on two entangled photons, physicists have yet again found that the photons seem to be communicating faster than the speed of light - at least 100,000 times faster. The researchers hope that their results might encourage theorists to come up with new explanations for the strange quantum mechanical effect.

That's kind of a funny statement because I'm sure you knew that before this NOTHING exceeded the speed of light be it a speeding body or "information". Now you're brushing it off as if the speed of light was just indeed the speed of light and not THE universal speed limit. This reminds me of times when mankind thought the speed of sound was the universal limit.

It is very easy to send information faster than light, you can do it right now if you want. Wrap two different coloured items identically and then get a friend to shuffle them without out you knowing and give you one whilst he keeps the other. Then separate yourself by 5 * 2.998*10^8 metres and open yours, you will instantly know which item he has, you brain will process this information in around 2.5 seconds beating light by 2.5 seconds. This kind of information transfer can occur from any distance, most physicists think information can travel faster than light anyway.
Information itself cannot travel faster than light even if the information is transmitted indirectly. This could lead to the fact that all attempts at physically observing a particle with an "entangled" relationship to another are slowed down, even though the particles are not connected in any other way other than by the information they carry.

This isn't a transfer of information, it's exactly the same as the example I provided to show how it doesn't work. No unknown is solved, nothing is changed in the system. You have all the information in one spot, split it up, and then open the box up at the other end. You had all the information in one spot at one point in time, so you already know that someone is going to have a certain part when it's all said and done, and it doesn't do anything for you.
However, if this experiment is done with entangled particles the results are quite different. When two members of an entangled pair are measured, one will always be spin-up and the other will be spin-down.
When the researchers measured several properties of each photon at its destination, they found that the particles could instantly sense the other´s behavior without any known communication. Although this correlation obeys the laws of quantum mechanics, it seems to defy the nature of space and time, at least from humans´ everyday perspectives.
