Since you're on YouTube, you probably know what a meme is; but what is it really and how does it go viral?

This is episode 1 of our animated series "Think Like A Coder." This 10-episode narrative follows a girl, Ethic, and her robot companion, Hedge, as they attempt to save the world. The two embark on a quest to collect three artifacts and...

In Parkinson's disease, certain kinds of neurons die over time, but it might be possible to reprogram other types of cells in the brain to replace those lost ones.

Hank introduces us to the relatively new field of evolutionary developmental biology, which compares the developmental processes of different organisms to determine their ancestral relationship, and to discover how those processes...

Another year, another security breach that could expose all of your information. Installing updates might be a good New Year's resolution.

Hank shares the nuts-and-bolts of the world’s first robot swarm, and explains what the creepy, cute and extinct animal known as Hallucigenia can teach us about evolution.

How does a computer work? The critical components of a computer are the peripherals (including the mouse), the input/output subsystem (which controls what and how much information comes in and out), and the central processing unit (the...

Reed Kroloff gives us a new lens for judging new architecture: is it modern, or is it romantic? Look for glorious images from two leading practices -- and a blistering critique of the 9/11 planning process.

Today we’re going to take our first baby steps from hardware into software! Using that CPU we built last episode we’re going to run some instructions and walk you through how a program operates on the machine level. We'll show you how...

More detailed brain scans reveal that the brain is more complicated than we thought! And cloned sheep might be healthier than we thought!

You might get the impression that all viruses are terrible, awful, no-good things that just wreak havoc on humanity. But, surprise: The truth is way more interesting!

All living things are made of cells. In the human body, these highly efficient units are protected by layer upon layer of defense against icky invaders like the cold virus. Shannon Stiles takes a journey into the cell, introducing the...

We know that our immune system watches out for us, but is there a way we could give it a leg up in spotting cancerous tumors?

People ask Google everything under the sun. One of the most commonly searched questions in the world is “What Is the Meaning of Life?” Let SciShow explain.

So now that we’ve built and programmed our very own CPU, we’re going to take a step back and look at how CPU speeds have rapidly increased from just a few cycles per second to gigahertz! Some of that improvement, of course, has come from...

Hank tells us three surprises about human DNA which we learned because of the Human Genome Project.

An algorithm is a method of solving problems both big and small. Though computers run algorithms constantly, humans can also solve problems with algorithms. David J. Malan explains how algorithms can be used in seemingly simple...

In the 20th century, most vaccines took over a decade to research, test, and produce. But the vaccines for COVID-19 were cleared for emergency use in less than 11 months. The secret behind this speed is a medical technology that's been...

Welcome back to SciShow News! Michael Aranda explains how a male's health affects their sperm.

Uploading your mind to a computer might one day let humans cheat death. The technology’s a long way off, but researchers are working on closing that gap. This episode was brought to you and inspired by the movie Self/less.

This is episode 10 of our animated series "Think Like A Coder." This 10-episode narrative follows a girl, Ethic, and her robot companion, Hedge, as they attempt to save the world. The two embark on a quest to collect three artifacts and...

Your body is made of cells -- but how does a single cell know to become part of your nose, instead of your toes? The answer is in your body's instruction book: DNA. Joe Hanson compares DNA to detailed manual for building a person out of...

How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer's "strength" -- and also its weakness.

Your body has all sorts of complicated processes going on, and a lot of them are carried out by incredibly powerful molecules. We're not talking nutrients -- we're talking about 5 of the molecules that keep you ticking!
