Even so, an encounter today between a large shark and Australian surfer Mick Fanning, who was competing in the Jeffreys Bay World Surf League competition (the J-Bay Open), broadcast live on television, has caused a few hearts to skip a beat.

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.

Pluto turns out to be pretty lively.

Not Las Vegas, perhaps, but more vivacious with geologic activity than we've ever known about, and for good reason: Pluto is currently almost 3 billion miles away from Earth, a dwarf planet spinning in the lonely last ring of our solar system.

What Do A Chlorinator And A Condom Tied To A Catheter Have In Common?

Slum dwellers near Calcutta get their water from a municipal pipe. Water coming out of the tap on the left is for bathing and so is untreated. The blue Zimba chlorinator is hooked up to the tap on the right, which is used for drinking water.

This isn't your average top 30 list. No Taylor Swift song is on it, it doesn't involve sports and it's not a listicle of the Internet's best cat videos. But it does have a device that adds chlorine to water so it's safe to drink — and a condom tied to a catheter that can stop bleeding when a woman is having a baby.

NASA's New Pluto Images Point To Geologically Active World

Originally published on Fri July 17, 2015 3:26 pm

In the center left of Pluto's vast heart-shaped feature – informally named "Tombaugh Regio" — lies a vast, craterless plain that appears to be no more than 100 million years old, and is possibly still being shaped by geologic processes.

Pluto looks to be a far cry from the dead body that many scientists had long presumed. As the New Horizons probe continues to report back from the fringes of the solar system, a word that Mr. Spock might have used sums up the reaction: fascinating.
