If you want to dive deeply into a particular topic, consider using Google's app for iOS instead of your other browsers. The big G has made it much quicker to find and explore articles and other content related to what you're looking at by adding suggestions at the bottom of page.

The cards could lead to Wikipedia articles about the genome-editing technique or the Saturn probe, they could link to NASA pages, scientific studies -- anything related to the topic, really.
