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. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal poop contribute enormous amounts of energy to our ecosystems.

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.

What do you get when you combine a lightweight, high-definition GoPro camera and an eagle? One of the best YouTube videos I've seen all year. At one point in your life, you've likely seen a bird flying and wondered what it would be like to have the opportunity to soar. This POV is likely the best we'll get to experiencing that rush. This particular video was shot in Chamonix near the Mer De Glace (Sea of Ice) - the longest glacier in France.

This week marks the 178th anniversary of Darwin's first exploration of the Galapagos Islands. This volcanic archipelago is one of the most biodiverse and unique places on the planet, with species that have remarkably adapted to their environment. Through observing the animals, Darwin made key insights that informed his theory of evolution. Here's a short documentary that captures the 10-day expedition: More info
