If you've been prescribed an expensive, cumbersome CPAP machine, you might want to know if it actually works. And while sleep doctors insist CPAP is the standard of care, out there in the real world, it's a little more complicated.

After the Chernobyl Disaster, researchers have been studying the movement of radioactive contamination all over central Europe. Fortunately, that radioactive contamination is decreasing in just about every living thing, except for one...

You’ve heard of Tyrannosaurus rex, but did you know they might have a mini-cousin called Nanotyrannus? And that “might” is serious, because researchers have been arguing about it for nearly 40 years and still haven’t gotten to the bottom...

We know that fossils are fragile, and volcanoes are destructive. So you wouldn't think that volcanoes are really any help when preserving fossils... but you'd be wrong! From the Laetoli Footprints to the Blue Lake Rhino, here are five...

The same technology that helps you rack up kills in your favorite FPS games also helps paleontologists solve million-year-old mysteries. Thanks to Dr. Anne Kort for helping us with this video!

Scientists have recently discovered the cells responsible for a deer's amazing ability to regrow antlers in just a few months. It may be the key to healing human wounds and broken bones faster.

If you've ever watched an animal sleep and wondered what they're dreaming about, science has the answers.

Alaska has the most volcanoes out of all the US states, but researchers think they don't have enough. Here's the weird science behind looking for Alaska's volcanoes, and what we've learned about volcanism along the way.

This month's Rocks Box is pyrite, also called fool's gold. But this fool's gold might not be so foolish, since we can use it to get all kinds of other minerals we really need, and it may be a key to getting real gold after all.

For years, scientists couldn't solve the mystery of strange pits on the floor of the North Sea. Initially they blamed methane seeps, but it seems like the pits were actually made on porpoise.

The nitrogen cycle is essential to life on Earth, but biological nitrogen must be fixed before it can be used. Scientists aren't sure how the first nitrogen became available... but it might have been volcanoes.

An entire field of science is dedicated to identifying the perfect indoor temperature. And it's a lot more complicated than simply setting the thermostat to 21 degrees Celsius (70 degrees Fahrenheit).

So we all know about the carbon cycle, and the water cycle, and maybe even the nitrogen cycle. But new research has figured out there's a salt cycle, too. Problem is, that same research has found that we already broke it. Here's what...

Look, we've all heard the rumors that giant pandas are an evolutionary dead end. But we are here to set the record straight and show you that these adorable fluff balls are a lot tougher than they seem.

If you could throw a potluck with all the oldest foods in the world, what would you bring? We asked ourselves that question and prepared a menu of tasty snacks for you to consider, from tamales and noodles to our favorite ancient boozes....

When it comes to a beverage menu, I don't usually want to see "tears" on the list. But these three animals do, including bees whose favorite drink is human tears!

Even when animal traps are humane, it seems pretty obvious that animals wouldn't want to get caught. But sometimes, there are oddballs that love getting trapped. Here's what we know about what can make some animals so darn trap happy.

We can get to Mars in 3 days, . . .sort of, maybe. In this episode of SciShow Space Reid Reimers explains the possibilities of photonic propulsion in use with space travel.

Move over, blue whale! Perucetus colossus, a basilosaurid whale that lived 39 million years ago, may have been the biggest animal ever. It has the heaviest skeleton ever found, which may make it the new largest animal of all time.

Can keeping calm before a surgery reduce negative outcomes? More than one study says "Yes."

It's that time of year where we round up all our favorite science discoveries of the year, and today, we're talking fossils. From a wild mosasaur with screwdriver teeth, to glittery gold fossils, and even a mammal-versus-reptile fight to...

Dark matter's most famous trait is its inability to interact with light, the particle version of which we call "photons". But in their attempts to figure out exactly what dark matter is, some scientists have proposed "dark photons".

We've all heard of a flu shot or a COVID vaccine, but there's a whole bunch of other health issues that researchers think we can use vaccines to prevent. From high cholesterol to substance abuse, researchers want our immune systems to...

Cancer is a complicated disease, and there's no simple blood test for early detection and screening to spot cancer in general. That might be changing thanks to LINE-1, a retrotransposon gene that doesn't do anything.
