Articles are helpful for more narrowly-focused (and often more recent) coverage of specific aspects of a topic.
These are good for getting a local and/or national perspective on your topic. Some news sources to try:
If you're not sure what subject area your topic falls under or if your topic is interdisciplinary, try

A note about journals: Depending upon the intended audience of the journal (scholarly, professional, general/popular), the writing may be too difficult to understand for a layperson or too simplistic for your research purposes. To strike a balance between too complicated and informative enough, you'll want to pay attention not only to the intended audience but also who's doing the writing to determine if it's authoritative and accurate. For example: an article on a disease may appear in a popular magazine, but if it's a signed article written by a medical doctor, that carries more weight than if it were written by someone outside the medical profession.
