Science and Philosophy

In modern physics, much of the research being done is on extreme conditions. The result is more and more strange and hard to believe theories. One of the hardest to understand is the theory of Quantum Mechanics. What is the role of the scientist to look into the implications of science? My question is does a scientific theory need a philosophy explaining the science, or should science be seperate from philosophy. Mainly the idea of the quantum wave function, since the wave function has to be collapsed but currently there is no theory of why quantum wave functions are collapsed.
