Using current awareness tools, like news sites and legislation monitors, is the best way to update your research.
If you are doing research online, the currency of your research will depend on the currency of your database. ALWAYS check the scope notes for date coverage and frequency of updates; you will often find these by clicking an icon of the letter i. If these notes are not readily available, run a simple date search to determine currency.
Blogs and social media can be an interesting source of up-to-the-minute interpretation of world events. Please be cautious with any of these sources--they are unofficial, unvetted, and possibly outdated, false, or biased.
