No they're not doing all they could, because if they stopped working on the science altogether and spent all their time trying to inform people what they just finished doing, then, of course, they would do more. Don't forget that they have a profession. Furthermore, that they went into this with the reason that they're interested in nature, and not in informing people. A lot of scientists have gone into science because they're not too interested in the relations of human beings. That is, that's not their central interest, so it becomes work to a certain extent to inform.
