Hank briefs us on a fascinating project that aims to map the anatomical and functional pathways of the brain - a neural network called the human connectome.

Feathers might have originated tens of millions of years before we'd thought, and a 3D rendering of ankylosaur nasal passages lends new insight into how they stayed cool.

Cheryl Hayashi studies spider silk, one of nature's most high-performance materials. Each species of spider can make up to 7 very different kinds of silk. How do they do it? Hayashi explains at the DNA level -- then shows us how this...

Hair can be so many different colors, but why do so many adults have gray hair?

It’s so easy to forgive a dog, especially when they start with those puppy dog eyes. As it turns out, those puppy dog eyes and the effect they have are no accident and the result of centuries of domestication.

We all have really different looking locks but what actually make our hair straight or curly?

Hank takes us through the bowels of the human digestive system and explains why it's all about surface area.

Researchers have been studying a promising option for male birth control, and we've learned a bit more about how regeneration works in hydras!

What do you get when you combine the strongest materials from the plant world with the most elastic ones from the insect kingdom? Super-performing materials that might transform ... everything. Nanobiotechnologist Oded Shoseyov walks us...

People have a lot of ideas about how they can protect themselves from the sun’s ultraviolet radiation, but many of those ideas just don’t hold up, and some make things worse!

Join the Amoeba Sisters a they explore different muscle tissues and then focus on the sliding filament theory in skeletal muscle! This video also briefly talks about muscle naming, some vocabulary (such as agonists and antagonists)...

Hank tells us the story of the complicated chemical dance that allows our skeletal muscles to contract and relax.

Cheetahs are fast. You know this. But which is faster: a cheetah, or a Tyrannosaurus rex?

Each time you take a step, 200 muscles work in unison to lift your foot, propel it forward, and set it down. It's just one of the many thousands of tasks performed by the muscular system: this network of over 650 muscles covers the body...

Imagine, for a second, a duck teaching a French class. A ping-pong match in orbit around a black hole. A dolphin balancing a pineapple. You probably haven't actually seen any of these things. But you could imagine them instantly. How...

Humans often take inspiration from nature when coming up with inventions, and this includes breakthroughs in fabric design that help to forward the fabulous and functional world of fashion.

Getting wet isn’t REALLY what makes wool shrink; it merely exacerbates the friction between the wool fibers, which is stronger in one direction than another, so when agitated in the washer or dryer, they...

You might not believe it, but the same chemistry that brought us bulletproof vests and modern sailing sails also gave us the technology to build your smart phone. But that doesn’t mean these chemists were thinking about these...

Today Hank wraps up our look at Connective Tissues with a discussion of its various types and a breakdown of what you can and can't easily break down. Also chicken.

When you think about robots, do you think of something made from metal? What if robots could have stretchy, flexible skin just like humans? How would they detect when someone tapped them on the shoulder or something rubbed against their...

In this FRAME feature, we examine the gigantic US farms capable of harvesting hundreds of tons of cotton per year. Grown across vast expanses of land, cotton is the most widely used natural fiber in the textile industry.
