The help of the Comments-module gives the single line that must be added at the end of the News Detail Template. I changed that line a little, in wrapping a little logic around, to only show the Comments for a specific News-category.
Logic added at the end of the News Detail Template.
As seen in this line, the only News category where the comments will appear to have the Blog-functionality, is the category Blog. I also additionally gave the date-format in the calling, as I needed to style the date of the comments different as well.{if $entry->category == 'Blog'}
{cms_module module='comments' dateformat="F d, Y H:i:s" modulename='News' pageid=$entry->id}
{/if}
