This week, researchers are getting ready to learn about earth and Mars, in places that you might not expect.

One year to eighteen months might seem like a while to wait for a COVID-19 vaccine, but there's a good reason finding and approving a candidate takes a whole lot of time.

Scientists are working to develop personalized cancer treatments, but one obstacle in the way is figuring out how different cells react to one another.

You may have read headlines suggesting that if you have allergies, you might be at greater risk of developing mental illness. But don't panic just yet. Hank unpacks these findings on this week's SciShow News.

Researchers are developing a flu vaccine with the potential to target many different strains at once. Also, bacterial meningitis may have something to do with special RNA.

Hank describes mitosis and cytokinesis - the series of processes our cells go through to divide into two identical copies.

During long, cold winters in medieval Europe, church organs grew gray, sickly-looking circles that spread over their pipes. People back then believed that this was the work of the devil, but as it turns out, it’s just some pretty simple...

All new products must pass through the "valley of death" before they reach the market. Many never make it out, and sometimes that's OK -- if they don't work, don't fill a need or for any number of reasons. One of the fields where this...

Whether you’ve got a lot of hair or absolutely none, it’s one of those things all of us have thought about at some point. And we’ve ended up with some… questions.

What do Charles Darwin, Michael Jordan, and Yoda have in common? They, like many other historical and fictive individuals, are bald. Scientists have long pondered, why do some people lose their hair, and how can we bring it back? Sarthak...

From robots to braces to the Mars Rover, see how a special kind of metal called shape memory alloys advance technology in everyday ways that we don't always realize.

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.

In this video Paul Andersen explains how energy can enter and leave a system. The amount of energy a substance can receive through heating or lose through cooling is measured using the specific heat capacity. Phase changing energy from...

Explore the cell cycle with the Amoeba Sisters and an important example of when it is not controlled: cancer. Table of Contents: 00:00 Intro 1:00 Cell Growth and Cell Reproduction 1:42 Cancer (explaining uncontrolled cell growth) 3:27...

You know what starvation is, but do you know what it does to you? Hank walks you through the three major metabolic phases of starvation, from burning sugars to, basically, self-cannibalism.

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep your warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Shini talks...

Cycles are a big deal in engineering. Today we’ll explain what they are and how they’re used in heat engines, refrigerators, and heat pumps. We’ll also discuss phase diagrams and the power of using renewable energy resources

The hair on your scalp can get really long, but your leg hair doesn't sweep the floor. Why not?

What's both edible, and capable of sending you an email to let you know there's explosives nearby? Spinach! Well, spinach with some nanotechnology embedded within it. Learn how Popeye's favorite veggie is involved in the field of plant...

Michael Aranda walks you through the crime-fighting science of forensic entomology, the study of insects used in criminal investigations. As if you needed more reasons to love bugs. But be warned: You might not want to watch this during...

Mister Brown and Squeaks are learning all about different cycles, or patterns, as they get ready for summer!

In this video Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment...

How the heck do we map out a planet without oceans? NASA had to figure that out when we sent the Mariner 9 probe to Mars. There's some tricky, yet fascinating science behind all of it! In this episode of Crash Course Physics, Shini talks...

In this video Paul Andersen explains the importance of mitosis and details the major steps in the cell cycle. He explains the importance of Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophases, and Cytokinesis.
