Oops! You drop your precious midnight snack on the floor! You just picked it up really quick, like less than five seconds, so it is ok to eat, right? But is the 5-second rule really legit?

Want to learn more about the topic in this week's video? Here are some key words/phrases to get your googling started: - Lifting Condensation Level (LCL): The altitude at which the water vapor in rising air begins to condense - Adiabatic...

Black Holes should have no entropy, but they in fact hold most of the entropy in the universe. Let's figure this out.

Paul Andersen explains how populations experience exponential. He begins by address the major players; N (population size) and r (growth rate). He models population growth in rabbits through four generations. He then shows you how to...

When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

Scientists have discovered an underground lake of liquid water on Mars! While this isn’t itself evidence for life on Mars, it does raise some new possibilities.

From the sharp mouthparts of mosquitoes to the sticky feet of geckos, researchers have found all kinds of amazing adaptations in the natural world that could be useful in the operating room.

What weird worlds are these video games creating?

While the Earth's oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth's grandest geological...

Marine archeologists accidentally found the world’s oldest known intact shipwreck, and their work scanning, diving, and exploring has given us some very cool insights into more than just our history sailing the oceans.

Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more...

NASA's Dragonfly -- a robotic rotorcraft-lander that's designed to hop across the surface of an extraterrestrial body -- is set to voyage deep into the solar system to explore Titan, Saturn's largest moon, in 2026. Planetary scientist...

As if you needed any more proof that alcohol just makes weird stuff happen, Quick Questions explains why alcohol can make you /feel/ warm, when it's actually making your body colder. You'll never think of brandy the same way again!

Michael Aranda sits in for Hank to talk about the forces of nature that conspired to form Typhoon Haiyan, the strongest tropical cyclone ever measured. Plus, what's neutrino astronomy? You're about to find out, because it's a thing now,...

Hank gets to the bottom of an exciting, and kinda weird, announcement from Russian scientists at the Vostok Research Station in Antarctica. Have they reached a 20-million-year old underground lake? Maybe! Is there a hoard of Nazi secrets...

We’ve probed some 250 kilometers into Jupiter’s atmosphere, and that’s raised some new questions about the mysterious planet. And we’ve taken another important step in looking for life on Mars by using a common chemistry process for the...

The lower Congo River is treacherous, turbulent, and very deep. While that might seem like an inhospitable habitat, hundreds of species of fish thrive there, including some that are really bizarre!SciShow is supported by Brilliant.org.

Whether it's robots under the sea, wave detectors in space, or star-power on land, this episode has big experiments covered.

As we walk through our daily environments, we're surrounded by exotic creatures that are too small to see with the naked eye. We usually imagine these microscopic organisms, or microbes, as asocial cells that float around by themselves....

Last week, NASA released some pretty cool Mars news: Curiosity found even more evidence to indicate the planet could’ve been habitable billions of years ago.

Margaret Wertheim leads a project to re-create the creatures of the coral reefs using a crochet technique invented by a mathematician -- celebrating the amazements of the reef, and deep-diving into the hyperbolic geometry underlying...

The global pandemic led to a drop in outdoor air pollution, but it also led to an increase in indoor air pollution - and our exposure to it.

SciShow News shares two amazing things from the deep past that have been discovered: a new ancient human relative, and a 30,000-year-old giant virus.
