There’s a lot of confusion out there about what is and isn’t a dinosaur. And you’d be forgiven for being kinda confused. Maybe paleontologists are just messing with us. Or… maybe the question of what is and isn’t a dinosaur goes deeper...

20 million years ago, the ocean housed a creature so colossal that its stomach could reach volumes of almost 10,000 liters— big enough to fit an entire orca. It was the megalodon, the biggest shark to ever live. So, what was it like when...

By overcounting how much carbon their forests suck up, and undercounting how much carbon their industries release, countries undercount their total carbon emissions.

On New Year's day, we said goodbye to George the Snail, marking the first extinction of 2019, and the way things are looking, it won't be the last.

Ratites have spread to Africa, Australia, New Zealand, and South America. And there are fossils of Ratites in Europe, Asia, and North America too. That's a lot of ground to cover for birds that can't fly. So how did Ratites end up all...

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 over....

Recent proof-of-concept studies showed that researchers were able to survey animals in an area simply by vacuuming up DNA in the air.

Trilobites are famous not just because they were so beautifully functional, or because they happened to preserve so well. They're known the world over because they were everywhere!

The wheat, corn and rice we grow today may not thrive in a future threatened by climate change. Cary Fowler takes us inside the Svalbard Global Seed Vault, a vast treasury buried within a frozen mountain in Norway, that stores a diverse...

Bees, they're important and amazing creatures, and with spring on the way we thought we'd share another round of our favorite bee episodes.
