Watch a butterfly drink turtle tears from a Yellow-spotted Amazon River Turtle (Podocnemis unifilis). Wait, what?
It’s true: butterflies and bees will drink turtle tears as a source of sodium and minerals. In turn, the turtles get their eyes cleaned. The video above was filmed in Peru by Ryan M. Bolton, photographer/videographer and trained conservation biologist. Farther below, there’s a photo in Ecuador’s Yasuní National Park by conservation photographer Pete Oxford. Via LiveScience:
Turtle tears are not the only source of such salts for butterflies; the insects also readily get the salt from animal urine, muddy river banks, puddles, sweaty clothes and sweating people, said Geoff Gallice, a graduate student of entomology at the Florida Museum of Natural History, who has witnessed butterflies flocking to turtle tears in the western Amazon rain forest.
This region is lower in sodium than many places on Earth, because it is more than 1,000 miles (1,600 kilometers) from the Atlantic Ocean, a prime source of salt, and is cut off from windblown mineral particles to the west by the Andes Mountains. Dust and minerals make their way into the Amazon from the east, sometimes all the way from north Africa. But much of this material is removed from the air by rain before it reaches the western Amazon, Torres said.

Photographer Todd McLellan has been on my mind ever since I saw this post on making an Inventor’s Box: a collection of tools and second-hand electronics for kids to disassemble, organize, wreck, rebuild, or reinvent into something completely different… you name it!
In this time-lapse video (or this one), watch Todd disassemble different kinds of machines so that they can be meticulously arranged and photographed. Here are two examples of the final product:
Then view his project, Things Come Apart, where he’s also photographed the same parts “flying” through the air.
McLellan’s photographs seek to challenge our disposable culture by making transparent all the things that we regularly throw away. He said he wanted to get inside the older objects to show the quality, beauty and care that went into the original manufacturing process.
"I hope people think a little bit more about the things they use. Not that people should have feelings for objects, but instead think about ‘reuse and recycle,’ not just ‘use and discard.’ "
The Chicago Museum of Science and Industry is featuring Things Come Apart until May 19th, 2013, or check out McLellen’s new book available for pre-order on Amazon: Things Come Apart: A Teardown Manual for Modern Living.

Swiss photographer Fabian Oefner works with the intersection of art and science. He takes perfectly-timed photos of brightly-colored paint being spun at high speeds. From the artist:
"Black Hole" is a series of images, which shows paint modeled by the centripetal force. The setup is very simple: Various shades of acrylic paint are dripped onto a metallic rod, which is connected to a drill. When switched on, the paint starts to move away from the rod, creating these amazing looking structures.
The motion of the paint happens in a blink of an eye, the images you see are taken only millisecond after the drill was turned on. To capture the moment, where the paint forms that distinctive shape, I connected a sensor to the drill, which sends an impulse to the flashes. These specialized units are capable of creating flashes as short as a 1/40000 of a second, freezing the motion of the paint.
We’d love to watch high speed, slow-mo video of this project. See more of Fabian’s images here, and then check out his painting in magnetic ferrofluid project.
