Everyone knows where Punt is, right? The Ancient Egyptians sure did — they traded with them for millennia. But apparently they were *so* familiar with its location, they never bothered to write it down for posterity. So archaeologists...

SciShow takes you inside the site of the world's worst nuclear disaster to show you how, nearly 30 years later, life has adapted and persisted.

Turns out, two atomic clocks are indeed better than one. And what role does sleep play in memory suppression?

As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And while we can’t know the future for sure, we can get a lot of good clues from the past.

Do popsicles give you toothaches? Do you wonder why that special toothpaste makes it all better? We've got you covered!

Your teeth contain traces of strontium isotopes that can reveal where you lived while they were forming.

They often don’t get as much attention, but North America had major cities long before European colonizers arrived, but the residents left behind no written history. How have archaeologists pieced together the details of these population...

Thanks to strontium, oxygen, and rings in a tusk, scientists now have evidence that extinct mastodons may have participated in yearly migrations.
