You and the professor have driven your DeLorean back to the past to fix issues with the spacetime continuum caused by your time traveling. But another DeLorean appears with older versions of you and the professor. The professors panic...

With an effective surface temperature of roughly 5,500 degrees Celsius, you might think water couldn't survive on the Sun. Well, scientists debated whether or not it was there for nearly a century, and it turns out, it can!

If you hear birds chirping in the trees, you might not think much of the different sounds you're hearing. But as it turns out, those tweets and chirps have a lot more in common with some of our complicated rules of grammar than you might...

While they are incredible engineering marvels, we don't think about bridges all that much. But there's a good reason we should all be thinking about our bridges, since there's a weird reason that more of them might be at risk of failure...

After Pluto's demotion to dwarf planet in 2006, our solar system went from having nine planets to eight. But about a decade later, some astronomers proposed there was another planet, larger than Earth, hiding in the Kuiper Belt. And in...

The concept of warm-blooded and cold-blooded animals is outdated because there are actually tons of different animal thermoregulation strategies.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

This video is about elastic and inelastic collisions in 1D, 2D and 3D - and how the collision of conservation of energy with conservation of momentum, plus a secret direction, results in a completely predetermined behavior for most...

Join the Amoeba Sisters on this introduction to the human Skeletal System! This video first introduces several types of skeletal systems found in different organisms before focusing on the human endoskeleton. Then, this video takes a...

Right now, experts say a vaccine for COVID-19 is a year or more away. But as far away as it sounds, it’s only within the realm of possibility because scientists are speeding up the vaccine development process in surprising ways.

What if, no matter how strong your password was, a hacker could crack it just as easily as you can type it? In fact, what if all sorts of puzzles we thought were hard turned out to be easy? Mathematicians call this problem P vs. NP, it...

Scientists have developed a new AI that can teach itself how to be the master of an ancient board game.

You’re probably aware that your blood can be A, B, AB or O, but it turns out that blood types can get a lot more complicated than that! *We made a mistake in the credits of this video: The writer of this episode was Alane Lim.

Did you know that a massive ancient flood triggered a thousand year ice age? 13,000 years ago, North America seemed to be thawing from a 2.6 million-year ice age. Then, a huge swath of Earth was suddenly plunged back into the cold for...

It's the year 2018, and we now know that flies like to ejaculate. But how does this tie into our understanding of addiction?

Big-brained scientists have found the mechanism that may have allowed their brains (and all humans') to get so big.

Oxygen is pretty great stuff, but this recently discovered organism couldn’t care less about oxygen. It breathes nitrogen and may offer a window into how the types of cells in OUR bodies may have evolved billions of years ago.

Working in the White House in the 1840s may have been more hazardous than we thought.

SciShow debunks the myth that you only use 10 percent of your brain. So, how much do you really use? And how do we know?

We're taught to be cool around strange dogs because they smell fear, and that might be true, but your fear is probably freaking them out too!

The oceans absorb a lot of CO2, leading to a variety of effects like ocean acidification. But you might not expect one of those effects: stronger lightning strikes.
