Chainmail might be known best as the fashion choice of certain medieval warriors, but that doesn't mean it's a relic of the past. Modern chainmail can be both practical and fashionable. And thanks to one team of scientists, we now have...

Great white sharks have nothing on these terrifying jaws. Some marine animals have adaptations that turn their jaws into harpoons, fishing nets, claw machines, and more.<b<br/>r/>

In 2020, students from the University of Texas proposed sending a fleet of rovers to the Moon that, for a price, would carve words and symbols into the surface for *you*, random human. And that got us thinking, how big would such a...

Science offers a way of discovering and understanding the world around us, driven by questions and tested with evidence. And it’s a twisty-turny team effort— you won’t find many lone geniuses out there, or straight lines from hypothesis...

You can dye your hair, you can get a tan, but the color of your eyes is pretty much set in stone - or is it? From weird diseases to temper flare-ups and even iris implants, here are just a few ways that your eye color might not be so...

CRISPR-based gene therapies are already changing healthcare for things like sickle cell disease. But CRISPR is bigger than just medicine, and it could revolutionize everything from food and agriculture to green energy fuels to...

In 2022, humanity threw roughly 15 billion dollars of gold into the trash. That's because gold plays a small but significant role in our electronics. E-waste is a major issue these days, and scientists are hunting for better ways to...

If you ask your favorite search engine where Earth gets the most hail, it's likely to spit out Kericho. But can you use exploding rockets to suppress that hail? That's one question both companies and researchers tested...

A lot of very smart people have been working for a very long time on vaccines for HIV/AIDS, and they've come up empty. Thanks to broadly neutralizing antibodies (bnAbs) and mRNA vaccine technology, that might be changing. Here's why we...

In November 2023, NASA's Lucy spacecraft flew by the asteroid Dinkinesh and made a startling discovery: not only does this small asteroid have an even smaller companion (named Selam), that companion is shaped like a two-tier snowman....

Humans aren't the only ones who refer to each other by name. Several species in the animal kingdom refuse to live in anonymity. <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...

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...

It's no secret that humans have big brains, especially compared to the rest of the animal world. But big brains require big energy to power them, and shifting around all our calories to fuel our massive brains was no small feat. From...

Inventing cutting edge medicines to cure devastating diseases is one thing. Getting them into patients is another. Today we talk about a scientist who figured out how to do just that.<b<br/>r/>

On its own, a huge DNA sequence is a meaningless pile of data — so, how do biologists figure out what it means? They turn to the power of bioinformatics! In this episode, we’ll learn what bioinformatics is, how it works, and how...

Bacteria often get a bad rap, but they’re some of our best partners in science and medicine! In this episode, we’ll explore what bacteria are doing with their DNA — including how they can trade it around. We’ll learn about chromosomes...

Even though it might seem like our bodies are on autopilot, there is a whole lot happening inside us to keep things moving. In this episode of Crash Course Biology, we’ll learn that our cells are in constant communication, reminding each...

AI in warfare is no longer hypothetical; it's inevitable, says Palmer Luckey, an inventor and founder of the defense technology company Anduril Industries. He takes us inside the high-tech arms race to build AI-powered weapons, "killer...
