Can there be a science of morality?

I have read comments by some neuroscientists saying that we may be able to come up with a scientific basis for morality. My feeling is that this is wrong-headed. We may be able to find links to moral instincts, but I don’t see how this can be turned into a full blown morality. Just as I oppose religious intrusion into scientific matters, I oppose scientific intrusion into spiritual matters. While I do not believe in a soul, I think that our ideas are emergent properties of our brains and that studying neuron behavior will tell us no more about ground rules for moral behavior than studying the molecular structure of chess pieces would provide help in playing chess.
