When using OneSearch, there are helpful tools to narrow down just to articles. In the Resource Type section, you can choose Articles, which will include scholarly journal articles and magazine articles. If you're really only looking for scholarly material, you may wish to choose Peer-reviewed Journals in the "Show Only" section above Resource Type.
If you're looking for more information on recent events, you probably won't find peer-reviewed articles. Scholarly articles may take a year or more to publish, so if you need current information, newspaper articles or other online resources may be a better choice.
