Bismuth crystals aren't just pretty to look at. If you can get pieces thin enough, they display something called the Anomalous Hall Effect. Physicists aren't entirely sure how they manage to do that, but that doesn't stop them from...

A spy presses a button on their suit and blinks out of sight. A wizard wraps himself in a cloak and disappears. A star pilot flicks a switch, and their ship vanishes into space. Invisibility is one of the most tantalizing powers in...

How Long To Fall Through the Earth?

Here's a conundrum: the same aerosol pollutants that harm human health also help cool the climate, says atmospheric scientist Sarah J. Doherty. Is there a way to clean up the air without warming the planet? Exploring the unintended...

Some placebos are far more effective than others, and they can lead to real chemical changes in the body.

Learn the about the physics that allows bikes to stay upright and in motion, even without a rider.

There's a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric. Here's a demo from the SciShow Rocks Box where you can see this for yourself - all...

Some funky orbits near the Kuiper Belt are hinting towards a brand new planet, the elusive ‘Planet X.’ Our friends Mike Brown and Konstantin Batygin of Caltech are working hard to finally spot the potential gas giant through powerful...

The universe is precisely 13.8 billion year old - or so our best scientific methods tell us. But how do you learn the age of the universe when there’s no trace left of its beginnings?

Earth’s magnetic field protects us from deadly space radiation. What if it were drastically weakened, as a precursor to flipping upside down? I mean, it has before … many, many times..

Spaceship Earth has a literal deflector...

We’ve been failing to detect dark matter for decades. Finally, the latest failure to detect dark matter may have actually proved its existence. One of these is true: either most of the matter in the universe is invisible and formed of...

After decades of improvement, the number of malaria deaths is on the rise again. So scientists are experimenting with a new kind of mosquito control, and it's not an insecticide.

When you think about the impact of climate change on the circle of life, you likely picture polar bears or Bengal tigers struggling in new conditions. But the impacts on the world go all the way down to the tiniest creatures who do some...

What do you see in clouds? Bunnies? Zombies? The face of Nic Cage? There are some kinds of clouds that, while rare, make even weirder shapes -- like pancakes, rolling cylinders, and shimmery rainbows

Drugging animals may seem like a bad idea, but you'd be shocked to learn what it can teach scientists about disease, biology & animal behavior! Join us for a new animal-focused episode of SciShow, hosted by the one and only Hank Green!

Singing in the shower seems to sound better, but what is actually happening to the sound waves in that soapy, tiled room?

You’ve probably heard that taking vitamin C or zinc will keep you from getting sick, but it turns out that those popular cure-alls don't actually work.

In elections, your vote may be influenced by design of the ballot itself, especially when you don’t have strong feelings about which candidate to elect.

We often think of the ocean’s tide as a simple rise and fall, connected to the motion of the Moon. But on any given shore, the reality is much more complex and oceanic scientists have realized recently that there’s another, more...

Did you know there are everyday practices that can reduce your risk of Cancer? Science can prove it. In a study published this week in the journal Frontiers in Aging, researchers propose a combination of simple strategies to help prevent...

Many folks in the southeastern US know that the invasive vine kudzu swallows cars, utility poles, and entire mountainsides. They may not know it also contributes to air pollution and even makes it harder for us to ensure that everyone...

A new strain of bird flu has been detected in North American birds for the first time in seven years. And U.S. President Biden is temporarily lifting the country's summertime ban on E15 gasoline.
