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...

If all goes well, we'll be sending astronauts back to the Moon in just a couple of years. And scientists have a lot to figure out before then, including the answer to a seemingly simple question: What time is it up...

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...

Leeches are bloodsucking parasites, and you wouldn't think they're great at protecting other species. Yet for some conservationists, these little vampires are one of the best tools available for conserving endangered and threatened...

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...

Who among us hasn't uttered the phrase "I'll sleep when I'm dead"? Well, sleep deprivation can totally kill you. But you might be surprised to learn what the actual cause of death is, and a technique you can use to stay awake for the...

Sometimes, an ancient document is lost to history. Sometimes, you find it covered in mold and written over by an ancient scribe. Fortunately, thanks to science, lost doesn't quite mean what it used to.

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....

If you've wandered down a supplement aisle recently, you may have come across a bottle for sale that has "anti-aging" ingredients to help your body make a molecule called NAD+, better known as nicotinamide adenine dinucleotide. Your...

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...

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...

You've probably heard that urine is sterile. And we're only just learning that's not true. Understanding the urinary microbiome could help us find new ways to treat kidney stones, UTIs, and even bladder cancer.

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...

Photosynthesis is a powerful process that is responsible for some of life’s most vital functions. In fact, consumers like us rely on photosynthetic producers to harness energy from the sun so that we can survive and thrive. In this...

What’s a human? And how did we become humans, anyway? In this episode of Crash Course Biology, we’ll meet some of our closest relatives and trace how we evolved into the brainy, inventive, complex species we are today.

Humans may have been around for a long time, but life has existed for way longer. In this episode of Crash Course Biology, we’ll journey through deep time to uncover the history of life on Earth. We’ll explore the big, game-changing...

When reading "Alice's Adventures in Wonderland," most readers visualize the queen’s croquet game play out in their heads. A few might see the scene in vivid detail. However, a small fraction of readers have a drastically different...

Two species of Demodex mites specifically inhabit human follicles. And not just some people’s— nearly everyone is thought to host mites. One person’s face might harbor hundreds or even thousands of individual mites. On any given day,...

A person’s genes alone don’t tell us enough about how to most effectively treat their cancer.
