When humans are gone, nature will reclaim our cities and break down much of what we've built. But some of the things we've made will last much longer than others, and they're probably not the things you'd expect.

To try to solve the puzzle of Lark Quarry, experts have turned to a special subfield of paleontology -- paleoichnology, or the study of trace fossils -- to reconstruct exactly what happened on that spot, on that day, nearly 100,000...

The unexpected discovery of an entirely new domain of life was pretty huge and surprising - even if archaea do just look like bacteria. But, in recent years, it’s been their connection to us that's turned out to be particularly full of...

In the early 20th century, Alfred Wegener's theory of Continental Drift laid the foundation for our modern theory of plate tectonics. And today we know something even more exciting: Pangea was only the latest in a long lineage of...

Given the option, few would choose to buy products that harm the earth -- yet it's nearly impossible to know how most consumer goods are made or where they're sourced from. That's about to change, says supply chain innovator Markus Mutz....

In the late 1800s, paleontologists in Nebraska found huge coils of hardened sand stuck deep in the earth. Local ranchers called them Devil's Corkscrews and scientists called them Daemonelix. It was clear these corkscrews were created by...

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch...

MU69 seems to be much flatter than we thought and the Gaia space telescope can tell us where galaxies have been and, maybe, where they're going.

It's virtually impossible to tell where a meteorite comes from, but in 2018, scientists were able to pull a feat of forensic astronomy and do just that.

Scientists have found a way to hack the visual process and generate shapes directly on the brain, so a person can see them without using their eyes.

Two long-time SciComm powerhouses face off to find out if either of them retained any relevant random facts from the many, many videos they’ve each produced.

Alwar Balasubramaniam's sculpture plays with time, shape, shadow, perspective: four tricky sensations that can reveal -- or conceal -- what's really out there. At TEDIndia, the artist shows slides of his extraordinary installations.

When we talk about 'English', we often think of it as a single language. But what do the dialects spoken in dozens of countries around the world have in common with each other, or with the writings of Chaucer? Claire Bowern traces the...

In this video Paul Andersen explains how the average value of the electric field can be determined by dividing the potential difference by the displacement. Equipotential lines can be used to determine the potential in an electric field...

The search began with a physicist checking for sources of static on phone calls in the 1930s, but it took several decades to finally make one of the biggest discoveries in astronomy, Sagittarius A*.

In standard notation, rhythm is indicated on a musical bar line. But there are other ways to visualize rhythm that can be more intuitive. John Varney describes the 'wheel method' of tracing rhythm and uses it to take us on a musical...

In part 3 of our special series on human ancestry, we investigate how closely related we all really are. Basic math tells us that all humans share ancestors. But you'll be amazed at how recently those shared ancestors lived. Thanks to...
