Scientists investigate the bizarre “intelligence” of slime molds, organisms which are neither plant nor animal. These single-celled blobs appear to learn and make decisions without a brain and can navigate mazes and create efficient networks. Can they also redefine cognition?
In the far reaches of the solar system, Uranus and Neptune dazzle with unexpected rings, supersonic winds and dozens of moons. And NASA's New Horizons gets a stunning up-close view of Pluto before venturing deep into the Kuiper Belt.
The rocky planets - Mercury, Venus, Earth and Mars - were born of similar material around the same time, yet only one supports life. Were Earth's neighbors always so extreme? Is there somewhere else in the solar system where life might flourish?
Dogs have long been dependable companions by our sides. But it wasn't always that way. A look at their closest living relative, the wolf, makes it clear why. Researchers reveal how humans tamed fearsome canines over tens of thousands of years, and how modern dog intelligence and behaviors have made them indispensable companions.
Stunning new archaeological evidence provides clues about the Egyptians who built the Great Pyramid of Giza–and how they did it. Join researchers as they delve into the logbook of a work crew and discover how the massive project transformed Egypt.
Sixty-six million years ago, an asteroid wiped out the dinosaurs in a fiery global catastrophe. But we know little about how their successors, the mammals, recovered and took over the world. Now, hidden inside ordinary-looking rocks, an astonishing trove of fossils reveals a dramatic new picture of how rat-sized creatures ballooned in size and began to evolve into the vast array of species.
Find out how the concept of Spy Creatures evolved from the original Bouldercam to the Penguincams that inspired the next-generation “spycams” featured in this series. It shows the painstaking work that goes into building the lifelike models and how the team deploys and operates the robotic cameras on location all over the world.
