Scientists working at a nuclear fusion facility in Oxford announced a record-breaking result. And while there's still a lot to figure out to make fusion viable, this brings us one step closer to realizing a technology with huge potential...

You probably have a vague idea of what sperm does, but not all sperm are created equal, and some have even developed unique adaptations to get where they're going.

Units are a major way we describe the world around us, and by looking at the scientists some of them are named after, we can get a sense of how we’ve learned so much about our universe.

When you imagine the energy of the future, solar power is probably in the picture – but in recent years, less than 2% of the world’s electricity has come from solar power. Here are 5 new inventions that are likely to change that.

In the animal kingdom, sleeping can be dangerous. Lying completely motionless and unconscious for hours at a time is just asking for trouble. There are, however, some sleepy risk-takers who spend almost all of their days snoozing.

Despite some bold claims, most supplements can’t really "boost" your metabolism, and the actual changes we can make to it are pretty limited.

Ovens are great for baking, cooking, and.... discovering quantum mechanics? In this fascinating episode of SciShow, Hank takes you through the science of quantum mechanics, and how ovens played a big part in their discovery.

It seems like a terrible idea to destroy and rebuild your own brain, but that is exactly what some ground squirrels are doing all winter long.

In what seems like an inefficient use of resources, these penguins always lay two eggs, but then ignore, discard, or just straight-up destroy the first one. What gives, penguins?

Airplanes are one of the quickest ways to get anywhere, but commercial jets haven't gotten much fast since the 1950's. Why is that?

We all know that warm air rises, but how does this scientific fact influence our weather and create those flows of air molecules that we know of as wind? In this episode of SciShow, Hank explains where wind comes from, what factors...

What is heavy water, and is it safe to drink? Heavy water, or deuterium oxide, has some pretty important scientific applications. But what would happen to your body if you actually drank it? Hosted by Hank Green.

Can you imagine a cup of tea that doesn't obey the laws of physics? One that pours out of the bottom of your cup while crawling up the sides to the top? Join Hank Green for a fun new SciShow super episode all about superfluids!

Snorkelers, surfers, divers. They all use them… wetsuits! So how do they work to keep you warm? It turns out layers of materials, and water itself!

This week's SciShow news brings you discoveries involving two of the most exotic substances on Earth - the world's rarest element and the world's oldest water. Two great tastes that taste great together? Stay tuned to find out.

Roots do more than hold plants in place -- they hold the planet in place. They're an important defense against drought and climate change, and of course, our actions are changing them.

Some people have this idea that dead batteries bounce if you drop them, but is it true?

You might have heard that exposure to unnatural lights from digital devices can hurt your eyes. But is that true? Hosted by: Stefan Chin
