Back in the Victorian Era, Englanders thought that the famous Roman Baths were so healing because there was radium in the water. And there was, but that wasn't the real secret. Turns out that the baths are teeming with microbes that...

There's a town in northern Mexico called Ojuela that's got a rich history of valuable mining industry, but nowadays is largely deserted. But it's getting a new, second life thanks to a type of mineral forming process fittingly called...

Who do you turn to when panic strikes in the middle of the night — and can AI help? Psychologist Alison Darcy shares the vision behind Woebot, a mental health chatbot designed to support people in tough moments, especially when no one...

The world is heading toward a massive copper shortage that could derail the clean energy transition, says mining expert Jeff More. He shows how advanced sensing technology could get us back on the right track, drastically cutting down on...

TED Fellow and renewable energy expert Norah Magero envisions an Africa that pioneers its own technological future, shifting the narrative from dependence and consumption to self-reliance and innovation. She shares how she developed...

A mathematician with a knife and ball begins slicing and distributing the ball into an infinite number of boxes. She then recombines the parts into five precise sections. Moving and rotating these sections around, she recombines them to...

In an exclusive preview of unreleased technology, designer and inventor Jason Rugolo unveils an entirely new kind of computer you can talk to like a friend. This "audio computer" — which can augment the sounds around you, translate...

Some birds' nests are works of art. These are not those. But we'll see why the terrible nesting habits of the cuckoo or jacana or even pigeons are the right thing for their survival.

We don't have to sacrifice our freedom for the sake of technological progress, says social technologist Divya Siddarth. She shares how a group of people helped retrain one of the world's most powerful AI models on a constitution they...

I think of my paintings as alarm clocks, says artist Isabella Kirkland. "They're reminders of what's at stake; the only problem is we keep pushing the snooze button." Investigating humanity's relationship to nature, she shares work that...

When we think of the ocean and what's in it, you probably think of stuff like fish, or salt, or seaweed. But there's a crystal that is so vital to marine life that they take dissolved materials in that salty water and build it...

The metaverse could be our key to making real progress in the fight against climate change, says engineer Cedrik Neike. Examining how AI-powered modeling eliminates the trial and error of wasteful industries, he explores how this...

We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann. He explores the infrastructure, innovation and investment needed to supply energy to 10 billion people, offering case studies from...

In 1997, NASA bought a Boeing 747SP for what might be both a super cool and super absurd purpose. Turn it into SOFIA, a flying telescope.

You’ve probably heard about the James Webb Space Telescope and seen some cool pictures. But why should astronomers have all the fun? How do we get to use this new toy ourselves?

Recently, the oldest quasar ever seen was discovered by the Gemini North telescope in Hawaii, the Magellan Telescopes at Las Campanas Observatory in Chile, as well as the Large Binocular Telescope in Arizona. In this first episode of...

Paleodictyon, a hexagonal-patterned fossil, is a bit of a mystery. We don’t even know if it’s a trace fossil, or the organism itself. So… what could it be?

While they are incredible engineering marvels, we don't think about bridges all that much. But there's a good reason we should all be thinking about our bridges, since there's a weird reason that more of them might be at risk of failure...

We think we know how mountains form. Plate tectonics causes rock to be pushed up at fault boundaries. Except that model is hard to prove, and a new study suggests it might actually be a lot more complicated.

2018 was full of exciting discoveries and incredible advancements in the field of science. So today, we are taking a look back at 2018 to highlight three more great science news stories!

Earthworms may be good for your garden, but they also have the potential to disrupt forest ecosystems across much of North America.
