Each snowflake is a six-pointed work of art, as cool and as individual as you are. But how does nature make snowflakes?

Two separate groups of biologists reported fusing entire sets of Saccharomyces cerevisiae chromosomes together, and surprisingly, the actual number of chromosomes might not be as important as we thought.

Conventional vaccine testing is a slow, years-long process. As thousands of people continue to die each day from COVID-19, bioethicist Nir Eyal proposes a radical idea that could dramatically accelerate the vaccine development timeline:...

With millions of Earth like planets around sun like stars in our galaxy alone, why don't we see intelligent alien life? Or any other life for that matter? It gets especially weird when you factor in new scientific revelations that life...

What if one day you woke up and were suddenly speaking with a completely new accent from somewhere you’ve never lived? It sounds like a movie plot, but this rare condition is known as foreign accent syndrome.

Wind is an ever increasing source of power worldwide, which means wind farms continue to be constructed. And choosing where to place those farms seems straightforward, but it might not actually be best to place the in the windiest places!

Fireflies, crustaceans, jellyfish -- lots of living things glow, and they do it for all kinds of reasons, some of which we haven't even discovered yet.

If you’ve ever been scratching a dog and seen them do the kicky leg thing, it’s truly adorable. But it might not necessarily be a feel-good thing.

Our immune systems are generally pretty great, but sometimes they can turn on us. And for some reason, these autoimmune conditions mostly affect women.

You know what's funny? Why people laugh. Hank talks about the science of laughter: what makes us laugh, what purpose it serves, and even what it can tell us about our mental and physical health. Hilarious!

The human body can have some odd, and sometimes gross, quirks. Like, why do we blush or laugh, especially when someone burps or farts? And what's even up with us having so much gas to begin with?! It sounds like it's time for a compilation!

How did life on Earth get started? Did life on Earth originate on another planet? Either Mars, or in a distant solar system? Could Earth life have spread to have seeded life elsewhere? Let's see what modern science has to say about the...

SciShow explores a place that's as beautiful as it is dangerous: Mexico's Giant Crystal Cave, where chemistry has created the world's largest crystals -- but in an environment so hostile that you'd only survive a few minutes if you saw...

We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first...

Hank gets into why sex is the preferred method of reproduction for most species - and it's not for the reasons you're thinking.

Hank tells us the stories of three experiments in biology that, with creativity and luck, changed science & the world with it in their work to solve the mysteries of the universe.

Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into...

If you teleported from sea level to the top of Mount Everest, things would go bad fast. At an altitude of 8,848 meters, you would likely suffocate in minutes. However, for people that make this journey over the course of a month, it's...

Scientists have once again used big, complex math equations to help us understand more about the universe we inhabit, this time about the origins of life on earth.

Earlier this year, fidget spinners claimed their place as the hot new fad of 2017. Some people, however, claim that fidget toys could help people manage symptoms of anxiety and ADHD.

Have you ever heard of the Peppered Moth? It's a great example of how living things can change because their environment has changed. And it's not just them! There used to be giant insects roaming the world, but they got smaller through...

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

SciShow Space takes you on a tour of Venus, a world with such an extreme environment that you might call it "Earth's evil twin."

We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...
