Wearing a mask is a cheap and easy way to help stop the spread of airborne infections like COVID-19. It's also a sign that you want to help protect other people and have them protect you… that we're all in this together. Here are some awesome slow-motion schlieren imaging experiments to demonstrate why masks work! Share with someone who needs to see this.

There is no phase of a human’s lifetime that is as strange and disgus....er....magical as the transition from childhood into adulthood - that handful of years that we call . . . PUBERTY. Why does it happen? How does it work? Why is it so weird? Join Joe in this whirlwind tour of the endocrine system to find the answers.

↓↓↓ More info and sources below ↓↓↓
Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living systems. In episode 4, we look at some surprising ways that species use teamwork in order to survive. Why is one African tree full of ants? Why are there birds nesting in girafe armpits? What surprising guard animal keeps an endangered butterfly larva from becoming wasp food? Welcome to the world of mutualisms and animal partnerships.
In Our Nature is a special miniseries produced by It’s Okay To Be Smart for PBS. Stay tuned for more episodes coming this summer, here on our YouTube channel!

Scientists overwhelmingly agree that our climate is changing, Earth is getting warmer, sea levels are rising, and it's primarily because of humans putting lots of carbon dioxide in the atmosphere.

Scientists overwhelmingly agree that our climate is changing, Earth is getting warmer, sea levels are rising, and it's primarily because of humans putting lots of carbon dioxide in the atmosphere. Yet 4 in 10 Americans aren't convinced. Here's what psychologists and sociologists have to say about why some people don't believe in climate science.

500 years before the Scientific Revolution, the mathematician Al-Hassan Ibn al-Haytham spent hours in a dark room studying the light that filtered in. Not only did he revolutionize how we literally see the world, he pioneered the scientific method that is now the backbone of modern science.

There is an absolutely weird, but surprisingly common phenomenon called sensory adaptation that you experience every day in countless ways without even realizing it. Without this very strange phenomenon, you would be lost, overwhelmed, and completely unable to navigate the external world. In this episode, we’ll explore the many ways your brain “tunes out” most of what’s going on around you so that you can be the high-functioning smart people that we know you are.

Just because something is difficult doesn’t mean it’s impossible. Over the past centuries, archaeologists, historians, and engineers have reconstructed a great deal of the technology and science used to build the Egyptian pyramids. This week we look at ancient Egyptian mathematics, building techniques, tools, and culture to reconstruct the Great Pyramid’s construction.

We all breathe the same air. Literally.
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub
Take a deep breath. Smell that? It could be a little eau de Einstein. Or maybe a whiff of Cleopatra. Here's an amazing thought: every time you breathe, you could be sharing air with everyone who's ever lived. A few million of the same air molecules that enter your lungs in a lifetime also entered Albert Einstein or Marie Curie's lungs! That's some smart air.
Earth's atmosphere is big, but not as big as many people think. All the air that keeps us alive is just a thin candy shell around our planet. In this episode, echoing the words of John F. Kennedy, I'll show you the science of how we all share the same air. So let's be careful about what we're putting in it!

Of all the species that humans have domesticated, dogs are our oldest animal friends. But how did a group of wolves become the furry pup at the end of the bed? New research is finally unlocking the paw-in-hand evolution of dogs and humans. In this episode we’re answering one big question: Did we domesticate dogs, or did dogs domesticate us?
Special thanks to our friends from MinuteEarth!

Would it surprise you to learn that fish and birds count in pretty much the same way that we do? And that infants can do math? Our animal brains deal with quantities in very specific ways, from quick counts of a few dots to how we perceive larger numbers. This "number sense" impacts our psychology, history, and behavior in the most fascinating ways.

Precious metals like gold, silver, platinum, and rhodium are expensive because they're rare in Earth's crust. But are they rare in the universe? Why is it so hard to make some of the chemical elements? Where do heavy metals come from, anyway? Turns out, we can blame it all on neutron stars and some oddities of the periodic table.
