I think of legacy as the weaving together of our stories passed on as a whole, says Haida storyteller Cohen Bradley. Highlighting the significance of potlatch ceremonies (or gift-giving feasts) and other Indigenous traditions of the...

Today, Squeaks and Mister Brown explore the world of plants with an experiment! They'll learn what plants actually need to grow, which can help them with their garden and even help feed people in space!

There's all sorts of life in the Redwood forest, but not just in the ground, different animals live in all layers of the Redwoods!

Traditional healing is used around the world, from acupuncture to laying of hands to yoga. How do these alternative remedies work to heal the body and the brain? As part of our series ScienceScope and in cooperation with the Pulitzer...

The opioid crisis has plagued poet William Brewer’s hometown in West Virginia. His vivid poems tell the story of the opioid epidemic from different voices and depict the sense of bewilderment people find themselves in as addiction...

With its infrastructure broken, the constant threat of starvation and a failed state, Yemen is on the brink of collapse. Less than half of its health facilities are functional amid a health crisis that has seen epidemics of preventable...

Some 1.3 billion people around the globe don’t have access to an electric grid. But solar startup companies say harnessing an abundant resource -- the sun -- can light up some of the world’s most remote areas. In this Kenyan village,...

By 2050, Earth’s population is expected to rise to 10 billion, while the resources on the planet continue to shrink. Researchers in the Netherlands are experimenting with one way to feed more people with less: growing crops indoors....

Kate DiCamillo, Newberry winner for "The Tale of Despereaux" (Mar. 30, 2004) (Author Interview)

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,...

In this video Paul Andersen explains how the greenhouse effect and greenhouse gases keep our planet warm enough to be habitable. He explains how greenhouse gases keep heat closer to the surface. He finally shows how increases in...

An introduction to the quantum behavior of light, specifically the polarization of light. The emphasis is on how many ideas that seem "quantumly weird" are actually just wave mechanics, applicable in a lot of classical physics.

In this video Paul Andersen explains how many possible solutions are developed in the design process. As many solutions to the problem are identified using a brainstorming process. These solutions are compared to the specific constraints...

What exactly is Consciousness? Well... that's kind of a gray area. In this episode of Crash Course Psychology, Hank gives you the basic ideas of what Consciousness is, how our attention works, and why we shouldn't text and drive......

The third and final part of the block collision sequence.

A throbbing, pounding headache. Bright zigzagging lines across your field of vision. Sensitivity to light, lingering fatigue, disrupted sleep. While an incapacitating headache is one of the most common symptoms, a migraine can include...

If you've ever been stuck at a red light on a country road, you know it can be annoying. No other cars for miles, but you can't shake the feeling that if you run the light, one will appear out of nowhere and slam into you. Today we have...

The third and final part of the block collision sequence.

The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

This video discusses how polarized sunglasses act as quantum measurement devices by demonstrating the strange behavior of light passing through multiple filters. It delves into the concept of quantum entanglement, Bell's theorem, and the...

Plants make oxygen using photosynthesis, but what happens to the air when those trees drop their leaves in winter?

Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

Can Batteries Power Everything? This video is about the physical and chemical limitations to electrolytic batteries, and how we might surpass the energy density and specific energy of lithium-ion batteries (like the Panasonic 18650...
