Long lines, metal detectors and pat downs are a common staple of the airport process. But are these security measures actually efficient and effective? Join Michael Aranda for a new episode of SciShow where he breaks down the science of...

Remember the last time you used your phone and it left a nice warm spot on your face? - Is that causing cancer? Michael Aranda tells you all about the radiation on your cell phone.

Antartica is a cold and isolated place, but intrepid scientists have found ways to make use of its environment, and turn it into one of the ideal places to study our skies.

The lingerling radiation from the ancient universe still surrounds us to this day.

Get to know the unique properties of quantum computers and the obstacles that have prevented this theoretical technology from becoming a reality. -- Quantum computers could eventually outstrip the computational limits of classical...

While most spacecraft are designed and built from scratch for one particular mission, the Phoenix Lander was pieced together from previous missions and rose from the ashes...all the way to Mars.

Do you remember the exciting rumor about NASA’s EMdrive? Well, now it’s official: NASA has created their own EM drive! Meanwhile, SpaceX has a plan which will make the internet more accessible.

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

We know we're not supposed to put metal in the microwave, but why? We don't microwave silverware but what about Hot Pocket wrappers? They have metal on the inside. How does that work? Let Michael Aranda explain.

You’ve probably seen the videos on YouTube turning grapes into fireballs in the microwave. Well, there’s a pretty cool scientific explanation for why a grape is perfect for making plasma.

Many people avoid using microwave ovens, fearing how it changes the molecular structure of your food, but studies have some evidence that may surprise you.

CubeSats have a lot of advantages, but they need a way to move and still stay small, and that means new miniaturized propulsion systems that can help us get these tiny spacecraft out into the universe.

Microwaves Explained in Ten Seconds

Hank explains the whole story about radiation - the good, the extremely helpful, and the bad.

In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...

Does Microwaving Make Food Harmful?

A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other...

Where is the centre of the universe? Where do astronomers look in space to see where the Big Bang originated?

Yes. Microwaves and radio waves are physically the same, i.e. both are forms of electromagnetic radiation. Some microwave rays can leak out and interfere with WiFi signals. We are basically constantly surrounded by electromagnetic...

A wave with both magnetic and electrical field components, which oscillate perpendicular to each other.
