Biology is the study of life—a four-letter word that connects you to 4 billion years worth of family tree. The word “life” can be tricky to define, but a shared set of characteristics helps biologists identify living things. In this...

In this episode, Jessi and Squeaks explore the many ways that caterpillars use to avoid being munched on by predators, and that it often comes down to how they look! <br/>

Cancer is a complicated disease, and there's no simple blood test for early detection and screening to spot cancer in general. That might be changing thanks to LINE-1, a retrotransposon gene that doesn't do anything.

Hairworms, sometimes called horsehair or Gordian worms, are mind-controlling parasites with a twist. A genetic study found these nematomorph worms are missing 30% of their genome, and we don't understand how they live without genes for...

AI can be a transformational tool in our fight against climate change, says Sims Witherspoon, a leader at the AI research lab Google DeepMind. Using wind power as her case study, she explains how powerful neural networks can help us...

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

Snakes have two penises (aka hemipenes) that come in a diverse array of shapes and sizes. And they could owe it all to their lack of legs.

Genetic tests can give you advice about what lifestyle, diet, and level of exercise are best for you. But you should take those suggestions with a grain of salt, because, when it comes to our bodies, our genes aren’t so much an open...

While viruses can be deadly and completely wreak havoc on humanity, they can also sometimes change our world for the better. Join Hank Green for a new episode of SciShow and learn the truth about the viruses that have shaped humanity...

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!

Chimpanzees and bonobos may be very close to us humans on the tree of life, but one of our differences is the way we store fat. That difference comes down to types of fat cells and our DNA. Hosted by: Hank Green

Jessi and Squeaks decide to answer some interesting questions from viewers like you, to teach you about sand, butterflies, and computers!

Historian George Dyson tells stories from the birth of the modern computer -- from its 17th-century origins to the hilarious notebooks of some early computer engineers.

When it comes to fighting COVID-19, scientists are throwing every bit of science we’ve got at it. A creative technique some researchers are looking into involves using gene therapy to fight this virus with… another virus!

Genetic tests can give you advice about what lifestyle, diet, and level of exercise are best for you. But you should take those suggestions with a grain of salt, because, when it comes to our bodies, our genes aren’t so much an open...

Scientists are working on creating organisms with designer genomes -- and someday, we might end up with bacteria manufacturing our jet fuel.

Two of the vaccines we have for COVID-19 have the distinction of being the first mRNA vaccines to see widespread use in humans. But how do they work, and how are they different from the litany of immunizations you probably got as a kid?

Some researchers trained the immune systems of leukemia patients to help keep them in remission. And other researchers found that it's possible to help African clawed frogs regrow lost limbs, an ability they normally lose once they hit...

This is episode 2 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...

Chimpanzees and bonobos may be very close to us humans on the tree of life, but one of our differences is the way we store fat. That difference comes down to types of fat cells and our DNA.

My friend Eric Schulze, awesome science guy and leader of Thirst DC helps me understand how genes and DNA write the book of life, and how reading that book has helped us learn that everything on Earth is descended from a common ancestor....

Axolotls are special salamanders. Not only to they stay in their juvenile form their whole lives, they can regenerate entire limbs! Studying how they do it could change the way we treat human limb injuries.

The secret behind medicine that uses messenger RNA (or mRNA) is that it "teaches" our bodies how to fight diseases on our own, leading to groundbreaking treatments for COVID-19 and, potentially one day, cancer, the flu and other ailments...

This is episode 8 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...
