In September of 2023, researchers detected a strange vibration all across the planet. They traced it back to a massive tsunami off the coast of Greenland, but the sound went on even after the wave was gone. As in, for nine full days....

It may seem like Earth isn't as well-decorated as its ring-bearing neighbors in the solar system, but new research suggests that may not always have been the case. Not only did our planet maybe once have a ring, but our ancient bling...

You might know about HDL or good cholesterol. And you might know about LDL or bad cholesterol. But do you know about LP(a) or Lipoprotein A? It's pretty common and pretty bad and we should talk about it.

From the Great Pyramid at Giza, to one-quarter of the Netherlands, to continent-spanning electrical grids, humans are great at making really BIG things.<b<br/>r/>

Why do we have wisdom teeth? They're just going to come in wrong and cause problems. Wisdom teeth are a souvenir from our early human ancestors, and we actually understand less about them than you might think.

Artificial Intelligence always takes over humanity in the movies when it gains consciousness. But even without getting into sentience, it's capable of influencing our lives in a lot of ways already.

Groundhogs are famous in North America for "predicting" when spring will come (and also that Bill Murray movie). But while they might make for terrible meteorologists, they actually play a valuable role in several other scientific...

Fecal transplants are often associated with treating intestinal issues, but they have uses far beyond that. In this List Show, we explore five surprising conditions they improve. <b<br/>r/>

Trees are dead inside. It's true: the xylem tissue that supports their trunks technically isn't alive. Archaeologists hate that because this problem, the old wood problem, can cause carbon dating to be off by hundreds of...

Octopuses are smart. Like, gather a posse of fish to do their hunting for them smart. And when the fish step out of line, the day octopus punches them. Really.<b<br/>r/>

Have you ever wondered why all the tasty parts of your box of cereal rise to the top? There's a lot of physics behind why mixtures can sometimes un-mix themselves, and if you use it to steal all the marshmallows, we won't...

Two billion years ago, an igneous rock in northern South Africa formed. Not long after, some bacteria crawled into cracks in that rock, and got trapped inside when the cracks got plugged up by a bunch of clay. But that bacterial colony...

If you've ever had lice, you probably think of them as a temporary annoyance. But for the salmon industry, these pesky invertebrates cause real damage. So here are some of the wildest ways that science helps us fight these...

ME/CFS, or myalgic encephalomyelitis/chronic fatigue syndrome, is way more than being tired at the end of the day. And, contrary to situations like that, exercise is the last thing you'd want to do.

Scientists are starting to find a strange connection between neurodegenerative diseases like Alzheimer's, Parkinson's, ALS, MS, and dementia. They all seem to follow on the heels of common but severe infections. And that means we might...

If you've ever heard about things like mammoths being found in permafrost, you may have an image in your head of what that looks like. But you might be wrong! So let's talk about what permafrost really is, why it's so important, and...

In the 1930s, a skeleton was discovered at the bottom of a well at the site of a medieval Norwegian fortress, severely injured and buried under large rocks. And to uncover his story, we need a combination of carbon dating, genetics,...

In the early 19th century, a French weaver named Joseph-Marie Jacquard was searching for a better way to make fabric. And in so doing, he managed to invent a loom that inspired the first proper computer.

Mount Everest is the tallest mountain in the world. But it didn't earn that title by coincidence. Even after achieving that superlative, it keeps growing taller today.<b<br/>r/>

Arrokoth, an asteroid in the Kuiper Belt, is the most distant object ever explored by the New Horizons spacecraft. And it's covered in sugar. Here's why that might be important for understanding the nature of life...

Blind people use the same part of their brains to recognize faces as sighted people, and can even identify a face from the sound of someone chewing. <b<br/>r/>

You may have heard about a new invasive menace in the US. The spotted lanternfly is a relatively recent arrival from China, and while they may be tiny, they have the potential to cause some serious problems. So let's talk about what...

Lung Cancer has been stigmatized as something that mainly happens when you smoke cigarettes. But non-smoking lung cancer may be a new disease changing the narrative.<b<br/>r/>

One fun fact about elephants is that they're a lot less likely to get cancer than other animals (including us). Another fun fact is that unlike most warm-blooded animals, their testes are deep inside their bodies. It turns out, these...
