Read MoreMeet the great horned owl, North America's biggest 'earless' owl — strong enough to carry off prey heavier than itself, fearless enough to eat skunks, and silent enough to sneak up on a mouse in the snow.
Read MoreCrows really do score like 5-to-7-year-olds on a famous reasoning test — but only that test, and only that species. The honest neuroscience is even more impressive.
Read MoreA praying mantis can technically bite, but it's almost always painless and far rarer than people think. Here's what actually happens when one grips your hand.
Read MoreOut of the flat Wyoming prairie, with nothing to warn you it's coming, a 386-foot tower of ribbed rock simply erupts from the earth. Geologists have debated its origin for over a century. Indigenous nations had an answer long before scientists arrived. And the two explanations might not be as different as we assumed.

Folklore insisted the sea deliberately chose which pieces survived the storm and reached the shore. A log that washed up whole was a delivery, a sign you'd been selected.

Read MoreIn 2011, a retired Brazilian fisherman named João Pereira de Souza nursed an oil-soaked Magellanic penguin back to life and released him into the sea. The following June, the penguin — now named Dindim — came back. Then again. Then again. For nearly a decade, he crossed 5,000 miles of open ocean to return to the one man who saved him.
Read MoreFor decades, one Dead Sea Scroll fragment was simply set aside — too darkened by age and mineral-laced sand to read. Then scientists flooded it with invisible light, and ancient Hebrew letters emerged from the void. What they found suggests scripture itself was still being written. And this may not be the last secret those desert caves are hiding.
Read MoreOne locust eats its own body weight in food every single day. Harmless, right? Now multiply that by 80 million — packed into a single square kilometer, moving like a living storm. The 2020 outbreak in East Africa was the worst in 70 years. Ancient Egyptians wrote about this. The Bible, the Quran, Sanskrit texts. Thousands of years of human civilization, and we still haven't stopped them.
