Musty, with hints of vanilla, coffee, and maybe fresh cut grass-- why do old books smell the best?

The world’s first artificial pigment, Egyptian blue, may help scientists prevent forgery and even save lives.

Fermi bubbles are made up of gamma rays, but where they came from is still up for debate. Did they come from a star-forming region, or the black hole at the middle of our galaxy?

We all have that coworker who insists that the houseplants on their desks are improving the office air quality, but is there any truth to that?

It’s been a great week for space explosions! Astronomers learned more about the mechanism that causes novas by looking at the nova V906 Carinae, and the brightest supernova ever recorded shed some new light on pulsation pair-instability.

Scientists have found a galaxy with almost no dark matter and we have finally solved the Leading Arm mystery!

Quick, think of three words to describe yourself. TIME'S UP! What did you think of? Chances are you thought of descriptive words that we call Properties. In this episode of Crash Course Kids, Sabrina talks about how properties help us...

How hot can things really get?

The other day I got bored and noticed this weird thing happened when I held my finger up to my eye, so I had to science it and figure it out! Let me know if you try these light-bending experiments too, especially that last one that I...

For a long time, we could only guess what color a dinosaur might be. But in the past decade, there has been an explosion of color.

Sam the bat would love to visit Mars one day, but he's going to need more than a few sandwiches if he's going to stay for long.<br/>

It's been one (tropical/sidereal/anomalous) year since I uploaded the very first It's Okay To Be Smart. Here's everything that's happened since!

We've found thousands of exoplanets over the years, but if we're going to find one that can sustain life, we need to take a look at the one planet we know that can, Earth.

Night blindness is real, and it can be caused by any number of things that affect the complicated mechanics of your vision.

Hank tells us about some developments that are being made in the dramatic area of laser tractor beams.

A little over a year ago, we covered a mind-blowing discovery on SciShow Space News. Some researchers even suggested that, if this was confirmed, it would be one of the biggest astronomy findings in years. Except, as it turns out… that...

A super bright flash in the sky might be the birth of a supernova remnant and it turns out there's more than one way to build a binary star system.

In this episode we explain why fire is red, gas flames are blue, and why you're too cool to glow.

Sunbeams shooting down through the clouds make for some great photographs, but what's the science behind these beautiful rays of light?

What is a Neutrino?

From the Avocado to Pando, we love trees! They do so much for us, from making oxygen so we can breathe, to cooling urban environments, to literally holding the ground together to prevent erosion! The SciShow team is joining

In recent years, scientists have come up with new ways to hack the physics of light, to invent the most powerful microscopes the world has ever seen.

In 1967, Moshe Safdie reimagined the monolithic apartment building, creating “Habitat ’67,” which gave each unit an unprecedented sense of openness. Nearly 50 years later, he believes the need for this type of building is greater than...

Grizzly bears stick to a mostly vegetarian diet in sync with plant growing seasons. However, as grizzlies' habitats grow smaller, food is harder to come by. Using NASA satellites, scientists track the shifting, interrelated patterns of...
