I don't offhand know of any good general sources for science news. Perhaps there aren't any, in which case a useful algorithm might be to look on physorg, and then whenever you see something interesting go to whatever source they cribbed it from.

(I'm not sure whether your question is intended to suggest that if I can't suggest a specific better alternative then I shouldn't be criticizing physorg. If it is, then I disagree with the general principle. Saying "X is bad in such-and-such a way" doesn't incur an obligation to suggest something else that does what X is trying to do but doesn't have that flaw.)
