We can track our history of eating just about anything back through the fossil record and see the impact it’s had on our evolution. Throughout time, part of the secret to our success as a species has been our early - and sometimes fatal...

For decades, scientists have been studying the cause of the Younger Dryas, and trying to figure out if something like it could happen again. And it turns out that what caused this event is the subject of a heated debate.

When you think of penguins, you probably think of the kinds you’ve seen in cartoons and movies. But there are at least 18 different kinds of penguins, including some that are tiny, some that live in hot places, and even some that spend...

Thanks to humans, old school apex predators are struggling to hold onto their perch at the top of the food chain. And now a new class of adaptable mesopredators are remaking the ecosystems they take...

From Ancient Greece to the 20th century, Aristotle, Freud, and numerous other scholars were all looking for the same thing: eel testicles. Freshwater eels could be found in rivers across Europe, but no one had ever seen them mate and no...

What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail -- what he calls "a very high-tech accounting system" of carbon. In...

If you've ever been to, or lived in, or even flown over the central swath of North America, then you've seen the remnants of what was a uniquely fascinating environment. Scientists call it the Western Interior Seaway, and at its greatest...

Sunning themselves on rocks or waddling awkwardly across the beach, it's easy to think of sea lions more as sea house cats. But don't be fooled by their beachside behavior. Under the waves, sea lions are incredible endurance hunters,...

The SciShow Science News Bureau brings us some GOOD news this week - Hank tells us about a newly developed vaccine for dengue fever, a newly discovered monkey species in the Democratic Republic of the Congo, and some happy pigs drinking...

We used to believe that our ancestors had clear roles: Men hunt, women gather. But new evidence suggests that some of the earliest big game hunters were women.

Dinosaurs were social animals, moving in herds, hunting in packs, but could they dance?

Pods of killer whales inhabit the waters of every major ocean on Earth. Each family is able to survive thanks mainly to one member, its most knowledgeable hunter: the grandmother. These matriarchs can live 80 years or more and their...

Are insects the key to brain-inspired computing? Neuroscientist Frances S. Chance thinks so. In this buzzy talk, she shares examples of the incredible capabilities of insects -- like the dragonfly's deadly accurate hunting skills and the...

Legendary skeptic James Randi takes a fatal dose of homeopathic sleeping pills onstage, kicking off a searing 18-minute indictment of irrational beliefs. He throws out a challenge to the world's psychics: Prove what you do is real, and...
