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...

The Moon is typically 380,000-ish kilometers from the Earth, so it doesn't seem like they have that much of a direct influence on one another. However, the presence of hematite on the lunar surface suggests our planet is causing the Moon...

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.

And thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert...

This Nobel Prize season, dive into the world of the super small for physics and chemistry. It's where the nanocars roam and phase transitions get really weird.

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.

One potential avenue for cancer treatment uses electricity not from any outside machine, but from within our own bodies.

Caviar or fruity ball? Whatever you like! Here’s a rundown of how to spherify your own edible bubbles and why they could help to reduce waste.

There’s no question that comets have been regarded as some of the most beautiful things in the night sky for thousands of years. But why are their heads often green but never their tails?

Grasshopper mice take scorpion venom that could kill a human and use it to numb their pain. What makes these tiny mice so hardcore?

We have many alternatives to sugar, but where are all the salt substitutes?

In this video Paul Andersen shows you how to write balanced equations that describe chemical changes. He then gives you a short introduction to balancing equations and uses the PHET site to practice this skill. In aqueous solutions an...

You’ve probably seen the videos on YouTube turning grapes into fireballs in the microwave. Well, there’s a pretty cool scientific explanation for why a grape is perfect for making plasma.

Given that Earth’s magnetic field helps protect its life-sustaining atmosphere, you might think that the stronger a planet’s magnetic field, the better. But as it turns out, some planets’ relationships with their magnetic fields are a...

Chemistry is the study of matter - stuff, and how it interacts with other stuff. Even though chemistry doesn't make a lot of news these days, chemists are making discoveries that change lives all the time. If Hank had to narrow down all...

Biology and technology grew closer together when scientists manufactured neurons that acted like those in a brain! And birds evolved to protect themselves in two ways: fight and flight.

Hank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the...

Hank teaches us why water is one of the most fascinating and important substances in the universe.

Understanding the mole and how to use it is essential to your success in chemistry. The mole just represents the amount of a substance. 1 mole of anything is equal to 6.02 x 10^23 which is known as Avogadro's number. This number tells us...

In this video, we'll explore what atoms and ions are, and what the differences are. We'll also talk about how they're used in chemistry and physical science.
