Science absolutely positively can tell you about ethics and morality.
Morality, including the moral instincts, consist in reciprocity within the limits of proportionality, where reciprocity consists of limiting our actions to productive, fully informed, warrantied, voluntary transfer( trade, consumption, harm, destruction, loss) of demonstrated interests free of imposition of costs upon demonstrated interests of others by externality. That’s morality. It’s got to be or evolution (physics) wouldn’t tolerate our existence as a species.
There is no difference between physics (involuntary change), economics (productive cooperation), and morality (social cooperation), except we have memory so can invest in and borrow from one another across time (. All that varies is the level of immorality tolerated given the stage of development in the current military, political, and economic circumstances.
So yes, science has told us what manners, ethics, morals, consist of. They cannot tell you what those range of actions will be in three years any more than economics can tell you that, because what constitutes reciprocity within the limits of proportionality, varies with the structure of production of polities, commons, goods, services, and information.
So we absolutely positively know what the physical and natural laws consist of – because they’re the same – we can judge borrow from one another or invest in one another and punish one another for violating those investments and borrowings (thefts, parasitism, free riding), and we do so by moral intuition we call “altruistic punishment’ – the payment of high personal costs of punishment of others to preserve the high value of trust in cooperation (borrowing, investing) in one another, because of the impossible-to-replace returns on cooperation – wherever cooperation is reciprocal: productive, fully informed, warrantied, voluntary, transfers, and free of negative externality.
And good luck refuting that scientific claim – because you will not be able to without violating it. It’s a physical law of conscious, cooperative, species beyond which no conscious cooperative species can survive.
