{♫Intro♫} The event that killed the dinosaurs might be the most famous mass extinction ever. And scientists are pretty sure they’ve identified the scene of the crime: a meteor crater in the Gulf of Mexico. But that event sixty-six million years ago is neither the only one in Earth’s history, nor the worst. Not by […]

7 Things We Don’t Know About the Ocean

Humans have done a pretty good job of exploring the Earth thus far, climbing mountains and crossing continents and planting our flags all over the place in the name of science. But one part of the world that has remained pretty mysterious to us also happens to cover more than 70% of its surface: the […]

When Birds Had Teeth

In 1861, a man working in a Bavarian quarry discovered a fossil that would change the way we think about birds.

(electronic music) – [Narrator] So this, believe it or not, is Silicon Valley. That’s Facebook’s headquarters there, like 15 hundred feet away, but a lot of the valley looks like this, marshland and empty wasteland. But there’s actually this big messy story happening right here in the middle of nowhere. It’s a story about humans […]

The internet connects more than half of the world’s population through an invisible web of servers, computers, and devices. It has changed our lives in countless ways by allowing otherwise separated people to interact and by providing access to vast amounts of information.

I usually stand here and tell you about exotic creatures that you’re never gonna see — extinct animals with unusual features, or strange body plans, or sizes that seem preposterous compared to the animals we know today. But there are some organisms that live among us, even though they’re really better suited to life in […]

500 million years ago, back in the Cambrian Period, a pioneering little mollusk floated up off the ocean floor. It had developed a way to use its defensive shell for a whole new purpose — buoyancy. It turned out that by filling its shell with gas, this mollusk could literally reach new heights, gaining a […]

[♪INTRO] Eradicating a species might sound like something that’s always bad. We put a lot of time and money into protecting life on Earth, not destroying it. But not all eradication plans target a species’ entire population — just the parts that end up in places we don’t want them to be. Invasive species can […]

The 10 Oldest Fossils, and What They Say About Evolution

Wouldn’t it be cool to be able to point at a fossil and know that it’s the first, say, plant, or four-legged creature, or insect? But identifying the first anything in the fossil record is hard for a few reasons. First, the fossil record is patchy, because things only fossilize by chance, and we haven’t […]

♪ Wasps seem to be best known for stinging people, ruining picnics, and generally being jerks. But believe it or not, our lives are actually a lot better because of them. Wasps are nuisance bugs, but they kill lots of other nuisance bugs and are important pollinators. And scientists even think that certain compounds in […]
