I recently came across a very useful website at Harvard that provides a quick look at various science updates by year.
Science Updates by Year - Harvard
There's a new science update each week of the year dating back to 2006 on this site. For example, the January 13, 2017 update is a "Catalog of Habitable Zone Exoplanets". Each update is a clickable link that takes you to the abstract of the article of the study leading to the weekly update. You won't have access to the actual article, but that's okay if you're just trying to get a basic idea of what is new in science. The abstract will give a general overview without bogging you down with the details. Don't get me wrong, details are very important, but if you're looking for general updates, the abstract will more than suffice.
