    human inquirynoununcountable

The fixed phrase in the interests of science, as Conrad uses it, carries the same lofty tone.

    Similarscientists, researchers

    Note

    Here the word becomes a speaker in its own right: it knows, it is rejected, it is thanked for a vaccine. It stands bare, with no article, and takes a singular verb, as in Dara Ó Briain's "Science knows it doesn't know everything." Headlines lean on it heavily. There it can blur into the body of scientific knowledge, so ask whether people or findings are meant.
