What can I do about newspaper with poor referencing?
Given that most newspapers don't have their own "on-staff" technical writers to handle such articles, I doubt that writing a newspaper and pleading with them to include more information about the publication will be very helpful. More importantly, providing large amounts of technical detail is frankly not what a newspaper is meant for. The best you could reasonably expect is that the web page for the article might include a link to the journal page. But you should probably not expect full details of the publication on the web page itself.

For sites and publications like Ars Technica, the situation is different, since they're much more science-oriented. Then it would be reasonable to politely email the author of the article you're interested and request that the additional information be added.
