There appears to be no way to block types of news, just sources. Time might have a good article on politics but I have no interest in Celebrity news. By blocking the whole source, then Time gets no clicks from me when I might like more their content. But if it's full of celebrities, then it is a waste of space. My Yahoo used to be good this way. Yahoo News should be tunable that way too. Or I just use Google or Apple News which does let filter out garbage (to me) news
