I could be wrong, but the essence of science is to use theory and logic to extract evidence of a useful law in the tangible world. It is to answer how questions, not necessarily why questions.
And works a two way street of proceeding from evidence to establish a theory, and also creating a theory that is testable to find evidence.
So to me, science tries to uncover the logic of cause and effect applicable to reality. Either they do that, or they shut up and calculate.
Everything of their philosophies hinges on whether or not it is workable with the evidence to test. String theory is very elegant, but can you test it, and quantum mechanics has so many inexplicable qualities too it, that they go for what works instead of concerning themselves with philosophical implications.
I think science needs the guidance of philosophy myself. And science likewise can throw philosophy into being useless.
