With the quantum entanglement experiment what exactly do they mean by "one particle instantaneously affects the outcome of the other" It sounds like if you measure the spin of one particle, the other particle immediately registers as the opposite spin without anyone touching the detector. Is this what they mean? 
 A: You ask :
$ \ \ \ \ \ \ $ Will Scientist 2 receive a measurement at 8:32 without touching the detector?
The answer is we don't know.
We believe that in the process of measurement of entangled particles, time has no meaning. We believe an even more amazing thing: that, if the two measurement events are separated by a space-like interval, the result of the measurements is decided upon by both particles. None of them is the leader, i.e. produces the result and conveys to the other particle. Both particles decide the joint result. 
Just imagine that the two labs are located in rockets in opposite movements, and that each scientist performs the measurement of his particle. Imagine also that from the point of view of a third scientist, on the Earth, both measurements are done at 8:32, Greenwich hour. The scientist in each rocket would claim the he measured first, and his measurement result was conveyed to the other lab.
Then, who is right? Which one of the measurements was independent, and which one just conformed itself according to the information received from the other? 
On the other hand, if the measurements are separated by a time-like interval, we can say which measurement was the 1st one. But, honestly speaking, not even in this case we are sure that the 1st experiment done decided alone on the result.
A: What do you mean "receive" a measurement? There is no faster than speed of light communication involved in case that's what you were implying. Scientist 2 will still have to measure but the outcome of the measurement will be pre-decided if Scientist 1 has already made a "space-like separated" measurement on her own spin.
To make it more precise: the results of two space-like separated spin measurements along the same direction on an entangled state of two spins will be completely (anti-)correlated.
