We've been using lab rats for over a hundred years, and they've been part of some of the biggest medical breakthroughs ever. But what comes next? From organs on a chip to computer simulations, here are some of the ways that science...

In the early 1960s, NASA rolled up to a US Navy facility in Pennsylvania with one goal in mind: stick its newly-minted astronauts into one of the most extreme centrifuges that has ever been built, and whirl them around really fast to...

Bivalves—animals like mussels, clams and oysters—might be a more familiar sight in a restaurant than a lab. But it turns out that studying them might help us learn more about our own health.

From a blacksmith's son, to one of the most repeated names in physics textbooks, Michael Faraday epitomized the spirit of scientific exploration

While it’s probably most famous for its role in gene editing, CRISPR does more than just that: its ability to precisely cut and alter DNA could lead to new antibiotics, faster diagnosis tools, and more.

SciShow welcomes back Diana Six to talk to us about current news on the Mountain Pine Beetle Outbreak. Then, Jessi Knudsen Castañeda stops by and brings a familiar friend whose anatomy may help scientists develop better hypodermic needles.

Dr. Orion Berryman talks with Hank about the cool chemistry going on in his lab, and Jessi from Animal Wonders brings in Prickle the Hedgehog!

Stem cells are widely believed to hold great promise in medical research because of their ability to transform into all sorts of other cell types, and scientists can grow it in living mice.

While it’s probably most famous for its role in gene editing, CRISPR does more than just that: its ability to precisely cut and alter DNA could lead to new antibiotics, faster diagnosis tools, and more. Chapters CREATING ANTIBIOTICS 1:07...

Today, in our final lab, Jabril tries to make an AI to settle the question once and for all, "Will a cat or a dog make us happier?" But in building this AI, Jabril will accidentally incorporate the very bias he was trying to avoid. So...

For creatures that look nothing like us, fruit flies have been able to teach us a lot about human biology as we’ve studied them over the past century.

Testing new treatments in other animals can help us spot complications or potential pitfalls, but the results don’t always carry over to humans, which means that safely going from animal to human trials is a lot more complicated than you...

With the right questions, and careful observation, a ghost story can transform from a spooky anecdote to a scientific experiment.

Researchers have developed ways to induce hallucinations, and though it sounds weird, it could also tell us a lot about mental health.

In this video Paul Andersen shows you how a cross between mutant and wild types of Sordaria fimicola can be used to show and measure frequency of crossing-over. He begins by reviewing the process of meiosis in a typical organism. He...

Paul Andersen starts with a brief description of enzymes and substrates. He then explains how you can measure the rate of an enzyme mediated reaction. Catalase from yeast is used to break hydrogen peroxide down into water and oxygen. ...

Paul Andersen starts with a brief description of diffusion and osmosis. He then describes the diffusion demonstration and how molecules move over time. He then explains the concepts behind the osmosis lab and how potatoes are affected...

Paul Andersen compares and contrasts mitosis and meiosis. He shows how you can count cells in various phases of mitosis to construct a cell cycle pie chart. He also explains how you can use the fungus Sordaria to calculate map units...

Paul Andersen shows you how to graph data by hand. He explains the required elements of a scatter plot with a best fit line. He shows you how to properly scale and label the axes.

We need to save Jabril and John Green Bot’s movie nights. Jabril generally likes action movies and John Green Bot likes romantic movies, but they need to find something that they can both watch and enjoy together. Today, we’re going to...

From land to sea to space, scientists are using incredible tools to make new discoveries. These are the ten largest instruments in use around the world.
