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.

It took mountain climber Aron Ralston 127 hours to amputate his own limb. But it only takes a few seconds for this crab to pull off its own claw after an unsuccessful attack from a group of birds.

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.

he White Salmon River in Washington state is flowing again as the nearly 100-year-old Condit Dam was disabled with explosives Wednesday. The reservoir draining took about 2 hours. Further demolition is scheduled in 2012. The event is a significant milestone for river restoration and dam removal nationwide.

Captain Dave Anderson of Capt. Dave's Dolphin and Whale Safari in Dana Point, California, at great personal risk, has recently filmed and edited a 5-minute video that contains some of the most beautiful, jaw-dropping, footage ever taken with a drone from the air of a huge mega-pod of thousands of common dolphins stampeding off Dana Point, California, three gray whales migrating together down the coast off San Clemente, California, and heartwarming close-ups hovering over a newborn Humpback whale calf snuggling and playing with its mom as an escort whale stands guard nearby, filmed recently in Maui.

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable "trophic cascade" occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix.
