Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.

While his disciples loved their roguish leader, Sun Wukong’s misadventures had spread chaos throughout the land. The Jade Emperor, watching from his throne in Heaven, decided he would no longer stand by as this monkey wreaked havoc...

So we all know about the carbon cycle, and the water cycle, and maybe even the nitrogen cycle. But new research has figured out there's a salt cycle, too. Problem is, that same research has found that we already broke it. Here's what...

Supernovae are only rare to the passive stargazer, but if you’re an astronomer studying them, you get to see some of the most brilliant explosions in the universe. Here are five of the most significant supernovae known to science.

The Milky Way galaxy is relatively calm by the destructive standards of the rest of the Universe, and compared to its own very violent past. But just recently we discovered that its violent past was much more recent than we thought - and...

How come sharks get to have endlessly regrowing teeth when humans only get one set our entire lives? And how come some other mammals get to cheat the system? From elephants to baboons, we'll learn why teeth don't grow back.

In 1965, MIT's Lincoln Laboratory saw their Lincoln Calibration Sphere 1 (LCS-1) launched into Earth orbit. It was an empty aluminum sphere and couldn't do any science of its own. But the world's most boring disco ball has played a huge...

Hank examines the zoological definition of monogamy, as well as some other breeding strategies that animals use.

Tweeting may not decrease your stress, but the twitter of some birds just might. And can we make people forget their memories?

Researchers have published a new method of guiding lightning strikes using a laser. And another team of researchers developed a new test that uses DNA as bait for respiratory viruses like COVID-19.

Nadine the robot has been unveiled, and as robotics technology gets more advanced, humanoid robots are looking more and more human. In this episode of SciShow News we explore how Nadine works and why a lot of people find it creepy.

Scientists know that the Y chromosome has been shrinking in size over millions of years, but recent studies suggest that it has more important genes, besides the ones that cause biological maleness. Hosted by: Michael Aranda

Moser's circle problem, and its solution.

Scientists know that the Y chromosome has been shrinking in size over millions of years, but recent studies suggest that it has more important genes, besides the ones that cause biological maleness.

Chlorofluorocarbons, or CFCs, seemed too good to be true when they were first created, and before long astronomers studying Venus' atmosphere discovered what could go wrong with this "miracle molecule."

Obviously most telescopes need to see the sky to do their job, but when you are studying a wave that can pass right through the earth, the best place for your telescope might be underground.

Back in 1862, soldiers fighting in the American Civil War noticed a strange blue glow on their wounds. It took a couple of High School students to figure out what it was.

These animals can detect heat through some fascinating biological mechanisms, and they are proving to be boons to the scientific community.

Usually, you can count on a river to flow in one direction, but some things can make it reverse course. Aside from being weird and surprising, these river reversals can often reflect geological changes and have long-lasting impacts on...
