Black holes warp space and time, squeeze matter to a vanishing point, and trap light so that it cannot escape. Black holes, with masses millions or billions times that of our sun, sit at the center of galaxies. How can black holes perform such stupendous tricks, and what can we learn from them?

What is the universe made of? How did it come into existence? Was there anything before it? Where did the laws of nature come from? As difficult as these questions are, scientists are grappling and attempting to address them with bold new ideas – and new experiments. By combining mathematical models with observations, they are […]

How can just two rules of Einstein’s 1905 theory of special relativity lead to seemingly paradoxical changes in the perception of time?

Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all life possible.

«Desertification is a fancy word for land that is turning to desert,» begins Allan Savory in this quietly powerful talk. And terrifyingly, it’s happening to about two-thirds of the world’s grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes […]

«A forest is much more than what you see,» says ecologist Suzanne Simard. Her 30 years of research in Canadian forests have led to an astounding discovery — trees talk, often and over vast distances. Learn more about the harmonious yet complicated social lives of trees and prepare to see the natural world with new […]

We now have a new understanding of the underground ecosystem. It turns out that fungi barter and trade with other organisms like little stockbrokers.

The mushroom biologist talks about the antimicrobial properties of fungi, how they can be used as potent insecticides, and how they may help boost the human immune system.

Mycologist Paul Stamets studies the mycelium — and lists 6 ways that this astonishing fungus can help save the world.

More than ten million years ago, the world was brimming with a wide variety of apes. Scientists studying the ones that are still alive today can learn a lot about human evolution—but they miss out on many clues that can only be found from the apes that went extinct. Watch to learn how fossil apes […]

Saccopteryx bilineata illustration courtesy of Gloria Gessinger When Ahana Fernandez and her colleagues trek through the rainforests of Central America, they keep their ears tuned for an unusual sound: high-pitched, repetitive chirping and squeaking. The noises come from greater sac-winged bat pups (Saccopteryx bilineata). Though they sound nothing like the babbling of human babies, the […]
