We all want green energy to stop climate change, and one option is hydrogen. But achieving green hydrogen is tough, so some want to consider so-called blue hydrogen instead. Support for this video provided by Gates Ventures.<br/>

We all remember the woes and trials of our adolescence. But what you may not have realized is that your middle-school bout with surging hormone's wasn't the first time you went through a sort of puberty. From surging hormones to hair...

Zabargad Island in the Red Sea is so crusted with peridot that it's fair to say the place is literally made of it. <br/>

Are there any non-human animals that take a task they don't want to do and think to themselves "Eh, I'll do it tomorrow"? Even if they know the task will be harder and/or more unpleasant by putting it off? One of our Patreon subscribers...

Humans have been hurling spacecraft at the Moon for over 60 years. But even with all that practice, it's still quite the challenge to successfully land something on the surface. Case in point: in August 2023, two missions attempted to...

Quantum mechanics gets weirder as you go to smaller sizes and higher energies. It’s strange enough for atoms, but positively bizarre when we get to the atomic nucleus. And today we’re going nuclear, as we dive into the weird world of...

Before the start of the Eocene Epoch about 56 million years ago--Antarctica was still joined to both Australia and South America. And it turns out that a lot of what we recognize about the southern hemisphere can be traced back to that...

The climate of the Sahara was completely different thousands of years ago. And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made...

Blood is one of the most revolutionary features in our evolutionary history. Over hundreds of millions of years, the way in which blood does its job has changed over and over again. As a result, we animals have our familiar red blood....

What color is a banana? Duh, it’s yellow. But what is yellow? Now that you mention it, how do we see color in the first place? That’s the series of questions that led me to making this video. It started simple and took me down a rabbit...

Why are trees and other plants green? Seems like a simple question. But the answer is full of surprises. Using a special camera that can pick up light just beyond the visible range, into the near-infrared, you’ll get to see trees like...

You probably have a bag of frozen corn in your freezer, or have chowed down on a buttery ear of corn at a cookout. But not only did it take thousands of years for humans to domesticate teosinte to corral it into what we now know as corn,...

The lab mice we use for genetic studies are not only closely related, but live out their whole lives in a sterile environment, so they don’t tell us everything we need to know about actual humans. The answer might be grabbing a wild...

Refrigeration and air conditioning are among the largest sources of carbon, and the refrigerants we use are greenhouse gases, too. But green refrigerants are on the way, from elastocaloric cooling to a method a bit like salting an icy road.

It might seem pretty dark from a human point of view, but for some animals, feasting on your own offspring is the best way to ensure you and your other babies might have a more successful life.

Growing food in space will be necessary to support the future of space exploration. And it won't be monoculture, either. Here's why astronauts will be growing whole ecosystems in space.

In 1926, Robert Goddard launched Nell — the very first (successful) liquid fuel rocket. But Nell wasn't built like other modern rockets, including a notable lack of casing and an exhaust nozzle suspended above the propellant tanks.

Most of us are stoked if we can get a stone to skip more than 3 or 4 times. The world record holder at skipping stones has 88 skips. Here's why science says that number is way too low.

The future of wind energy is solarpunk. At least according to some manufacturers who want to put wind turbines on kites, blimps, or just generally up in the air where wind can generate green energy and fight climate change more efficiently.

Over the past few years, astronomers have discovered their own kind of UFO called Odd Radio Circles, aka ORCs. They're a little too round, and a little too invisible at non-radio wavelengths, to immediately know what they are and...

Even though math and art feel like polar opposites, it turns out computer algorithms and calculations can help us see masterpieces in a new light. From using wavelet decomposition to study Van Gogh to using convolutional filters in...

What if the treatment for one of the most daunting psychological conditions were a party drug? New research suggests that might be coming.

Teeth are so well preserved in the fossil record that they make the best, most informative fossils we can find, from phylogenetic studies to learning about the evolution of the human brain.

If you take a look at all the impact craters in our solar system, the vast majority are nice, neat circles. But why? Meteorites and asteroids strike planets and moons at all sorts of angles. Where are all the elliptical craters?
