You've probably heard that climate change is leading to rising sea levels, which is bad news for lots of islands. But for some islands like the Maldives, rising waters are making them... bigger?



Correction: We mixed up east...

In the history of space travel, there are a few famous animal astronauts (or cosmonauts), like Laika the dog and Ham the chimpanzee. But you might not have heard of Félicette, who in 1963 became the first -- and so far only -- cat to...

Correction: This is Watt's law, not Ohm's law! Our math was right but our name was wrong.



We need green energy yesterday. And it so happens that nature regularly sends huge bolts of electricity at us out of the sky. So what...

Climate disruption threatens food security around the world, but it's especially dangerous for fish farmers. Here's how high-tech climate information services can help then adapt.<b<br/>r/>

There's a tree species that used to be all over the world. And now, they can only be found in a secret valley in the mountains in Australia. This is the story of the rise and fall of the Wollemi Pine, including how some new tech might...

"Water, water, every where"...or so that one poem goes. And it's kinda right, because there's way more water INSIDE the Earth than on the surface. But scientists still don't know with certainty exactly how Earth got all of that...

Frogs aren't known for their fabulous manes, but the claws of frogs are helping us learn why humans have hair -- thanks to a homeobox gene and a weird evolutionary shift.<b<br/>r/>

Scientists have studied what gifts are most appreciated. And while there's some nuance in giving presents and money, there's a third thing you can give that may be even better. <b<br/>r/>

Fluorescence isn't just a cool effect that turns your white T-shirt neon purple under a black light. Its discovery opened our eyes to a whole new field of science and engineering. And it's all thanks to a crystal called fluorite....

Over the past three decades, astronomers have discovered thousands of planets beyond our solar system. But while some of them might be the right size and mass to be some kind of Earth 2.0, we don't know if any of them is truly...

When caterpillars undergo metamorphosis and become butterflies, their brains melt into goop. Neuroscience says they shouldn't remember anything about their past lives. So why do studies show that they do?

When fishermen cast their nets, they often catch a lot more than the species they're after. Those unlucky creatures are called bycatch, and it's a huge problem in the industry. Fortunately, scientists have been working hard to solve it...

Coral reefs are fighting for their very survival these days, and scientists are looking for ways to help—including testing underwater AC systems, and 3D printing what one might describe as artificial coral cyborgs.

Low-E windows have reduced the amount of energy required to heat and cool our buildings, a critical step in fighting climate change. But new research suggests we've lost something beneficial in the process.

In 2023, Italian and Spanish authorities busted a major counterfeiting ring. Their product? Olive oil. From fake caviar and scallops to imitation maple syrup, there are a lot of pricey foods that fraudsters love to fake. Here's how...

We've known for a while now that Neanderthals and humans interbred and swapped genes. But do you know what traits you have that came from your Neanderthal cousins? From early rising to immune boosting, here are a few traits that you...

In 2024, astronomers announced they'd discovered the brightest (or, technically, the most luminous) object in the known universe. And it's a cosmic engine powered by the hungriest black hole in the known universe.

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...
