Ants have one of the most complex social organizations in the animal kingdom; they live in structured colonies that contain different types of members who perform specific roles. Sound familiar? Deborah M. Gordon explains the way these incredible creatures mate, communicate and source food, shedding light on how their actions can mimic and inform our own behavior.

The kayakers were paddling through a marine sanctuary near Puerto Madryn as they reached a pod of whales. They were surrounded ever so calmly, then hoisted onto the back of a whale. The duo captured the event on a GoPro camera and uploaded the incredible footage to YouTube.

While there's no shortage of weird and wacky ideas in science fiction about what creatures from other planets might look like, few are quite as remarkable as those that can actually be found right here on Earth.

A sea turtle rescue center in North Carolina cares for and rehabilitates injured sea turtles, and returns them to the ocean amid cheering crowds. Sea turtles are resilient, but they are slow to recover. So the Karen Beasley Sea Turtle Rescue and Rehabilitation Center spends a lot of time and effort to help save loggerhead and other Atlantic Ocean turtles.

Every year, thousands of snakes gather at the Narcisse Snake Dens in Manitoba, Canada. It's billed as the largest gathering of snakes anywhere in the world.

We live in a world of unseeable beauty, so subtle and delicate that it is imperceptible to the human eye. To bring this invisible world to light, filmmaker Louie Schwartzberg bends the boundaries of time and space with high-speed cameras, time lapses and microscopes. At TED2014, he shares highlights from his latest project, a 3D film titled "Mysteries of the Unseen World," which slows down, speeds up, and magnifies the astonishing wonders of nature.

Trees create immense negative pressures of 10's of atmospheres by evaporating water from nanoscale pores, sucking water up 100m in a state where it should be boiling but can't because the perfect xylem tubes contain no air bubbles, just so that most of it can evaporate in the process of absorbing a couple molecules of carbon dioxide. Now I didn't mention the cohesion of water (that it sticks to itself well) but this is implicit in the description of negative pressure, strong surface tension etc.

When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C.
