Planetary scientist Joel Levine shows some intriguing -- and puzzling -- new discoveries about Mars: craters full of ice, traces of ancient oceans, and compelling hints at the presence, sometime in the past, of life. He makes the case...

In this video Paul Andersen explains how the location of matter can be determined at the nanoscale using the wave function. The absolute value of the wave function can be used to determine the probability of finding matter in a...

If we take care of the land, the land takes care of us, says Indigenous leader Valérie Courtois. As climate change continues to devastate the planet, Indigenous guardians are helping to honor our responsibility to the land, monitoring...

For centuries, people have viewed swamps and wetlands as obstacles to avoid. But for photographer Mac Stone, who documents the stories of wildlife in Florida's Everglades, the swamp isn't a hindrance — it's a national treasure. Through...

Poop kind of stinks, but the stuff inside of poop can tell us a lot about the natural world.

Since the dawn of humanity, an estimated 100.8 billion people have lived and died, a number that increases by about 0.8% of the world's population each year. What happens to all of those peoples' bodies after they die? And will the...

Everyone has the right to a clean environment -- but major disparities exist when it comes to who faces the consequences of pollution. Environmental justice leader Peggy Shepard points to the disproportionate impact that hazardous...

More detailed brain scans reveal that the brain is more complicated than we thought! And cloned sheep might be healthier than we thought!

Tourette Syndrome in popular culture is often simplified to a poorly timed foul mouth, but that’s only a small part of the story—or sometimes not part of the story at all.

So, a mantis shrimp's claws are pretty strong... so strong that they can produce a bubble that's about as hot as the sun and collapses with a flash of light when they snap... and scientists aren't quite sure how they do it!

Some people take aspirin or ibuprofen to treat everyday aches and pains, but how exactly do the different classes of pain relievers work? Learn about the basic physiology of how humans experience pain, and the mechanics of the medicines...

Neuroscientist and inventor Christopher deCharms demonstrates a new way to use fMRI to show brain activity -- thoughts, emotions, pain -- while it is happening. In other words, you can actually see how you feel.

About 150 years ago, scientists found the two main areas that are responsible for language production and comprehension in the brain. But it turns out they might have over-exaggerated what these parts actually do.

How do cells in your body differentiate into other types of cells? Explore cell specialization featuring stem cells and their role in cell differentiation.

You'd think if we can tell when a star is about to implode that we could predict when a giant hole is about to open up here on earth and ruin our day. So why are sinkholes still so hard to predict?

As far as we know, there's only one thing in our solar system sophisticated enough to study itself: the human brain. But this self-investigation is challenging because a living brain is shielded by skull, swaddled in tissue, and made up...

Today humanity produces more than 1,400 tons of carbon every minute. To combat climate change, we need to reduce fossil fuel emissions, and draw down excess CO2 to restore the balance of greenhouse gases. Like all plants, trees consume...

The rat's tail plant, or Babiana ringens earns its name for the distinct stem that grows above its flowers. But what's the purpose of this odd looking appendage?

Today we're going to take a look at mineral extraction -- or the removal of rocks and minerals from the Earths' crust -- and examine how this human activity impacts all aspects of Geography. We'll focus on the Democratic Republic of the...

Keith Bellows gleefully outlines the engineering marvels of the camel, a vital creature he calls "the SUV of the desert." Though he couldn't bring a live camel to TED, he gets his camera crew as close as humanly possible to a one-ton...

The HMS Challenger embarked in the 1870s to survey the world’s oceans. The data the expedition collected is still being used over 100 years later to inform what we know about climate change.

Oceanographer Paul Snelgrove shares the results of a ten-year project with one goal: to take a census of all the life in the oceans. He shares amazing photos of some of the surprising finds of the Census of Marine Life.

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...
