The smartphone has given us a whole new genre of cultural expression: the selfie.

If you're into selfies, it's safe to say you've probably taken one, and maybe wished you didn't have those dark circles under your eyes.

Flowers, bugs and bees: Stephen Buchmann wanted to study them all when he was a kid.

"I never grew out of my bug-and-dinosaur phase," he tells NPR's Arun Rath. "You know, since about the third grade, I decided I wanted to chase insects, especially bees."

These days, he's living that dream. As a pollination ecologist, he's now taking a particular interest in how flowers attract insects. In his new book, The Reason for Flowers, he looks at more than just the biology of flowers — he dives into the ways they've laid down roots in human history and culture, too.

In one of this year's most intense international competitions, the United States has come out as best in the world — and this time, we're not talking about soccer.
