Luckily, we live in a time where we don't have to worry about smallpox anymore. It's a horrible disease, but through smart vaccination techniques, we took it from killing millions worldwide, to being eradicated from the planet!

Exoplanets have taught us a lot more about planets than our solar system could ever teach us, from what happens when they’re born, to what happens when their stars die.

Can you grow a human bone outside the human body? The answer may soon be yes. Nina Tandon explores the possibility by examining how bones naturally grow inside the body, and illuminating how scientists are hoping to replicate that...

Today, we'll explore the materials electrical engineers work with. We'll look at high-conductors, insulators, and how low-conductivity conductors can be used to generate light and heat.

Today we’ll explore more about two of the three main types of materials that we use as engineers: metals and ceramics. We’ll discuss properties of metals, alloys, ceramics, clay, cement, and glass-ceramic materials. We’ll also look at...

Though not everyone is excited about it, plastics are pretty much everywhere. But what problems are they causing and is there anything we can do to solve those problems?

We have some good reasons for wanting to make fake wood, but wood is complex and intricate. Can we create a good wood substitute?

Magnetic Levitation

Plastic is quickly becoming a problem and we're eager to point fingers, but honestly, the reason there's so much plastic everywhere isn't just because of human negligence.

Learn about some materials that seem like they should belong in science fiction, but actually exist today!

With exoplanets, often we want to know if they are Earth-like and whether they might host life, but we can also learn a lot from planets that are nothing like Earth.

Your cell phone is mainly made of plastics and metals. It's easy to appreciate the process by which those elements add up to something so useful. But there's another story we don't hear about -- how did we get our raw ingredients in the...

We're continuing our look at engineering materials with third main type of material that you'll encounter as an engineer: polymers. They're made of long, repeating chains of smaller molecules known as monomers and today we'll explore...

In this episode SciShow Space we talk about the aether...which hasn't been proven.

For centuries, billiard balls were made of ivory from elephant tusks. But when excessive hunting caused elephant populations to decline, they began to look for alternatives. John Wesley Hyatt took up the challenge. In five years, he...

Today we’re going to start thinking about materials that are used in engineering. We’ll look at mechanical properties of materials, stress-strain diagrams, elasticity and toughness, and describe other material properties like hardness,...

You're minding your own business, looking at blankets, when suddenly you feel something heavenly. Now you are petting an inanimate object and thinking about naming it and bringing it home. Why do some fabrics feel so soft?!

Phones, TVs, solar panels, and electric car batteries are all made of some rare and unusual elements. As our modern world creates more and more of these technologies, will things go from "rare" to "nonexistent" and what will we do then?

Your closet is likely full of all kinds of materials -- leather, cotton, nylon and polyester, to name a few -- that contribute to fashion's sustainability crisis. Biomaterials investigator Dan Widmaier explains how we could look to...

It's an old cliche: an opera singer hits a note so high, it breaks a wine glass. It may seem over the top, but with a little science (and an amp), you too can break a glass like the finest soprano!

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Paul Andersen describes the defining characteristics of the domain Eubacteria. He begins with a quick description of the phylogeny of bacteria and horizontal gene transfer. He then surveys the structures of a bacteria; nucleoid region,...

Paul Andersen surveys the Kingdom Fungi. He starts with a brief description of the fungi phylogeny. He describes some of the major characteristics of fungi; heterotrophy, cell walls of chitin, hyphae, sessile. He describes the...

Today we’re talking about heat transfer and the different mechanisms behind it. We’ll explore conduction, the thermal conductivity of materials, convection, boundary layers, and radiation.
