Make Google Now more useful with a few taps on the screen

Customize Google Now by tapping on the three dot overflow menu
Besides eliminating stories about a particular topic, you can stop Google Now from sending you any stories at all in the future. You can also tell Google Now when you're done with a particular story, or ask to customize the feature. All of those options are yours when you click on the three dot overflow menu from any story.
It's easy to miss certain things when you're setting up your Android handset, and one of them is setting up Google Now just the way you want it. But now you know how easy it is to make the feature more useful to you.
