I don't think we're there yet for science. Perhaps for math proofs, but that's a very different domain ultimately since we know the rules of the game in a way we don't with science.
First math and CS, where formal logic dominate, and AI can check/verify its own answers very quickly. Then physics, downstream of math. Then materials science, which in some cases is practically a branch of physics. Then chemistry more generally. Then biology. Then various social sciences.
Oh, it's going to move up the old ladder, from bottom to top:
