The least amount of work on your part would be, as I've suggested, to leave the science threads in the news forum, where they rightly belong, and when necessary to admonish disruptive posters to stay off a thread -- regardless of what might be a disruptor's motives. Ditto if the reverse should happen on the religion forum.
For an example of a news thread that involves evolution, you might take a brief look at this:
[Michigan Gov. Candidate] DeVos says he wants intelligent design taught in science classes. This is typical of why the science threads are "news" and shouldn't be banned, or shunted off into a marginal forum.
