Neil deGrasse Tyson does a good job of explaining the difference between modern science and philosophy at the 1:02:00 mark in this video: http://www.youtube.com/watch?v=9zXYTwuwsyI
Tyson appears to distinguish between the two on the basis of topics under investigation, but not by any difference between the scientific method and the methods used by philosophers. I am not sure I agree with this distinction from an epistemological point of view.
