Interesting concept. I guess I never thought of it before, but I would agree that many of my science professors that I have had do have a philosophy of science, though maybe that would be an insult to philosophy.
As succinctly as I can state it, it would be that everything comes together to back up the idea that there is no intelligent design, that no God could exist, and that if evidence is contrary to popular scientific thought, then it's just that we don't yet understand it. One professor told me that intelligent design wasn't an option because it couldn't have existed, it couldn't exist because there was no God, and there was no God because that would infer intelligent design, which does not exist. Essentially, he was starting at the conclusion to determine the validity of the the evidence that was the basis for the conclusion.
Even from a philosophical standpoint, this sounds pretty rogue. Yet I was more amazed that my fellow students sat there in oblivion to the circular logic that had just passed before their eyes. Does anyone think anymore? Even atheist students should have challenged that logic.
