Is it somehow possible to force a no_cache link with tx_news?
<n:link newsItem="{newsItem}" settings="{no_cache:1}" uriOnly="1"/>
The link should look like this:
http://domain.com/no_cache/articleurl
If you want to disable caching for your news item, you can set the no_cache on your page.
you can also take a look at the viewhelper class of tx_news to see if this is possible. If not, you can add an additional parameter yourself
