Tinnitus, or ringing in the ears, often...

Hairworms, sometimes called horsehair or Gordian worms, are mind-controlling parasites with a twist. A genetic study found these nematomorph worms are missing 30% of their genome, and we don't understand how they live without genes for...

Zabargad Island in the Red Sea is so crusted with peridot that it's fair to say the place is literally made of it. <br/>

The cosmological equations that so beautifully describe our universe make an uncomfortable prediction: interpreting them in the most straightforward way, they tell us that the universe may be infinite. Or not; it could turn out that the...

Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We love the idea of fictional elements with miraculous properties that science has yet to discover. But is it really possible that...

Objective Collapse Theories offer a explanation of quantum mechanics that is at once brand new and based in classical mechanics. In the world of quantum mechanics, it’s no big deal for particles to be in multiple different states at the...

It was pretty impressive when LIGO detected gravitational waves from colliding black holes. Well we’ve just taken that to the next level with a galaxy-spanning gravitational wave detector that may have detected a foundational element of...

Since the very beginning of quantum mechanics, a debate has raged about how to interpret its bizarre predictions. And at the heart and origin of that debate is the quantum jump or quantum leap - the seemingly miraculous and instantaneous...

The results are in - on this weeks episode of Spacetime we reveal the answer to our Asteroid Challenge, as well as our T-shirt winners! Check out who saved the world!

Today, billions of people around the world start their day with caffeine. But how and why did the ability to produce this molecule independently evolve in multiple, distantly-related lineages of flowering plants, again and again?

Figuring out what this creature’s face actually looked like would take paleontologists years. But understanding this weird animal can help us shine a light on at least one way for ecosystems to bounce back from even the worst mass...

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...

It’s important to us that you understand how big this beaver was. Just like modern beavers, it was semiaquatic -- it lived both on the land and in the water. The difference is that today’s beavers do a pretty special thing - one that the...

Nunalleq, a village in what’s today southwest Alaska, seemed to have thrived during the Little Ice Age. How did this village manage to survive and prosper during this time period? And what caused this period of climate change in the...

Dinosaur mating behavior has been the subject of a lot of speculation, but what can we actually say about it from the fossil record?

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...

As revolutionary as teeth were, they would go on to disappear in some groups of vertebrates. But why?

People have been discovering the traces and remains of prehistoric creatures for thousands of years. And they’ve also probably been telling stories about fantastic beasts since language became a thing. So, is it possible that the...

For decades, scientists have been studying the cause of the Younger Dryas, and trying to figure out if something like it could happen again. And it turns out that what caused this event is the subject of a heated debate.

People say insects are the food of the future. They’re more environmentally sustainable and more humane than other sources of animal protein. Can they really catch on in western diets? I’m a pretty adventurous eater, but I’ve never...

Our bodies are mirror images of lobsters and other arthropods from back to belly. We've know since the early 19th century that our guts and nervous systems are inverted from theirs, but only recently has molecular biology shown us why....

It never gets dark anymore. Not REALLY dark, anyway. Not like it used to. Light pollution is not only making it more difficult to see the night sky, but it's also affecting our health. For the past century and a half, since the dawn of...

In the early 20th century, pregnancy testing required a slippery piece of equipment: a female African clawed frog. For decades, hospitals and research labs had a trusted supply of these handy creatures, employing their help in testing...
