You may think of particle accelerators as massive underground tunnels like the Large Hadron Collider. But a new generation of accelerators are small enough to fit on a coin. Now the challenge is making them useful.

Arrokoth, an asteroid in the Kuiper Belt, is the most distant object ever explored by the New Horizons spacecraft. And it's covered in sugar. Here's why that might be important for understanding the nature of life...

Why is there something rather than nothing? Well the answer may be found in the weakest particle in the universe: the neutrino. For over half a century Fermilab has been the premier particle accelerator facility of the United States and...

Deep in a Sardinian mine, researchers are constructing an experiment that hopes to solve what's known as The Worst Prediction In The History of Physics, and pin down the true identity of dark energy.

Last week, the recipients of the 2017 Nobel Prizes were announced. We take a closer look at the winners of the Physiology and Chemistry Awards, whose breakthroughs change the way we study sleep, and allow us to look at microscopic...

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

A clever mechanical proof of Snell's law.

Blu-rays can hold about ten times more than DVDs because Blu-ray players use special blue lasers to read them. But it took a while for scientists to figure out how to make those lasers work.

Thanks to Qualcomm for sponsoring a portion of this video.

May 23rd, 1967 could have been the beginning of the end - all thanks to the sun.

The first time scientists found exoplanets, they were orbiting something very different from our sun: a pulsar.<br/>

We might be getting a little closer to making interstellar travel a reality just not for humans.

Last week, engineers announced two possible lunar habitats: a big pillowy space closet and lunar lava tubes.

We need more solutions for our energy needs, and one idea is straight out of science fiction: Solar panels, in space.

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

"Punkin Chunkin" is the United State's annual contest to see whose homemade machine can hurl a pumpkin the farthest (without explosives!). Every November, thousands of amateur engineers converge on a farm in Delaware to put their...

Scientists have created beams of light that are slower than a car! Not only that, but with the literal flick of a switch, they can freeze that beam of light in place!

You can break the speed of light in your back yard! (but don't worry, Einstein is still right)

A clever mechanical proof of Snell's law.

Time travel is a staple of science fiction stories, but is it actually possible? It turns out nature does allow a way of bending time, an exciting possibility suggested by Albert Einstein when he discovered special relativity over one...

The coldest materials in the world aren't in Antarctica or at the top of Mount Everest. They're in physics labs: clouds of gases held just fractions of a degree above absolute zero. Lina Marieth Hoyos explains how temperatures this low...

Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.

Why is the sky blue? It's a question that you'd think kids have been asking for thousands of years, but it might not be that old at all. The ancient Greek poet Homer never used a word for blue in The Odyssey or The Iliad, because blue is...

Improve your understanding of molecular properties with this lesson on the fascinating property of chirality. Your hands are the secret to understanding the strange similarity between two molecules that look almost exactly alike, but are...
