It’s a sunny day at The Fort, so Squeaks and Mr. Brown are watching videos from the past to remind themselves of all the fun experiments they can do when it’s sunny outside!

Summer is nearly here, and that means Squeaks and Jessi will be spending lots of time playing with dirt in the garden! But it won’t just be those two out there making their garden grow big and beautiful. They’ll be getting help from lots...

We know diversity, equity and inclusion (DEI) boosts creativity and profits, but progress has been slow: today, nearly 90 percent of Fortune 500 CEOs are white males. It's time for leaders to become "rock stars" of inclusion -- and that...

Can AI help us see beyond our human capabilities? Through a kaleidoscopic blend of technology, nature and art, neural artist Sofia Crespo brings to life animals that push the boundaries of creativity and imagination. Her artistic...

Paul Andersen details the first 7 of 13 labs in the AP Biology Curriculum. The following topics are all covered: Artificial Selection, Hardy-Weinberg Equilibrium, Comparing DNA using BLAST, Diffusion and Osmosis, Photosynthesis,...

Paul Andersen reviews the major concepts within the fifth unit of the new AP Biology framework. He starts with a description of both DNA and RNA. He explains how DNA is copied during the S phase of mitosis. He explains how...

In this video Paul Andersen explains the importance of models and visual representations in an AP Biology class. Science practices are overarching skills and knowledge required to be successful in an AP Biology classroom. Models for...

Being attacked by a predator can be scary, but tiger moths have a very distinguished way to survive predatory bats. Meanwhile, scientists have presented findings on the importance of microbial ecosystems beneath the soil.

Colors: you see them every day, and you probably have a favorite. Pigments, light, and even noise all color how we experience the world.

Skin is one of the most powerful predictors of health, yet nearly half of all new dermatologists admit to feeling uncomfortable identifying health issues on darker skin tones -- resulting in poorer health outcomes for patients of color....

Greenhouse gases are colorless, scentless and invisible, making them exceptionally hard to measure. Fortunately, some tools and techniques can help -- one of the most powerful being artificial intelligence, says green technologist...

There's a compound found in squid skin that they use to change color and protect their cells, but it could also help us fight some of the most common disease-causing microbes out there.

In this video Paul Andersen explains how scalar fields can be used to show the distribution of scalar quantities. The most important scalar fields in AP Physics 2 deal with electric potential. Scalar addition can be used to combine...

Did you know that bees can remember things? It's true, and it's thanks to Dr. Charles Henry Turner that we know so much about insects!

Michael Aranda substitutes for Hank again in this week's News to tell you about the winners of the 2012 Visualization Challenge, an annual competition run by the journal Science that selects the most elegant and educational graphics,...

Have you ever wondered what color is? In this first installment of a series on light, Colm Kelleher describes the physics behind colors-- why the colors we see are related to the period of motion and the frequency of waves.

When you’re learning about science for the first time, it can be easier to break things down into a simpler form, and you can end up with a few misconceptions about the world. But sometimes this is the first step to understanding that...

Hank Green interviews Scishow's Chief Editor Blake de Pastino who explains his interest in writing about science, paleontology & anthropology. Special guest Jessi Knudsen Castañeda brings corn snakes for everyone to play with.

It's easy to assume a cat's coat pattern is based exclusively on genetics, but that isn't entirely the case for Siamese cats. Their unique coloration comes from a combination of genetics, a fragile enzyme, and losing heat from little...

Where do glaciers and icebergs get their beautiful blue color? This unique blue might be nature's most brilliant, and the color arises in a very special way thanks to some surprising interactions between light and water molecules. Who...

The animal kingdom boasts an incredible diversity of eyes. Some rotate independently while others have squiggly-shaped pupils. Some have protective lids, others squirt blood. But which creature has the best sight? Which sees best in the...

Jessi has a secret message she wants to share with Squeaks, but first they'll need to use some special ingredients to reveal it.

Feeling disconnected from creating art within classical conventions, artist Georgia O'Keeffe began experimenting with abstract drawings that defied easy classification. Using the shapes and rhythms of nature to capture her internal...

How many people does it take to make a cup of coffee? For many of us, all it takes is a short walk and a quick pour. But this simple staple is the result of a globe-spanning process whose cost and complexity are far greater than you...
