The world of energy is a confusing place. What's better, nuclear or solar? What's the difference between fluorescent bulbs and LEDs? What's the difference between energy and power? And what the heck is a kilowatt-hour?!
In this video, we give you a tour of the essential principles behind the energy machine that puts fuel in our tanks and brings electricity to our homes. To be a good energy citizen, you need to speak the language

The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let’s journey back to the origin of life, as best as we know it, from the RNA world do the last universal common ancestor of everything alive today.

How do zebras get their stripes? How do leopards get their spots? And how do giraffes get their giraffe-shaped thingies, whatever they are called? Would you believe the answer is… math? This is the story of a WWII wartime codebreaker and his quest to decode nature’s most beautiful patterns. Alan Turing uncovered a simple code that explains everything from stripes to spots and all the patterns in between… he was just too far ahead of his time. Only recently have biologists found evidence that his pattern-forming system

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.

The idea of the lone genius creating everything isn’t just misleading. It’s harmful and wrong. Innovation thrives when people work together, and rather than nice linear paths, new ideas come from chance events and unexpected connections. This video tells the story of one such invention, and offers a new idea about how new ideas are really born.

We've heard news of "peak oil" and "the end of the oil age" for years now, but we keep coming up with ways to find and pump more of it to the surface. Rising CO2 levels and the changing climate that results from burning fossil fuels mean that we should probably stop using oil sooner rather than later, though
Let's take a look at history and see how we've used different fuels, so that we might figure out when and how to make oil a thing of the past

Money. We all use it. But is it real? I mean, you can touch a coin or bill, but who decided that’s worth anything? And what about all those 1’s and 0’s getting swapped and traded by computers thousands of times per second? How are those worth anything? We trace the history of money, from physical barter to bitcoin, and discover that money isn’t just a lie we all agree to share, it’s been built on the back of technology and invention for millennia.

Why do Africa and South America fit together? Anyone who’s ever looked at a map can see that Earth’s continents are kind of like a jigsaw puzzle. The idea that continents are constantly moving and weren’t always in their current spots is a pretty obvious idea, right? You might be surprised to learn that geologists only accepted that idea recently in the past few decades, and it figuring out how plate tectonics and continental drift work required some pretty strange evidence.

Greetings, fellow Homo sapiens. Our species is the only remaining member of the genus of upright, walking apes known as Homo. Where did we come from? Our history just got a whole lot more complicated (in a good way) thanks to some incredible new fossils unearthed in South Africa over the past few years. I got to visit them, and the scientists who discovered them, to learn their story and ours. Meet your cousin: Homo naledi #homonaledi #humanorigins #evolution

Thank you to:
-Lee Berger, Marina Elliott, and Becca Peixotto for letting me meet Neo and for explaining their science!

Optical illusions are fun, but they can also teach us a lot about how our brains work. In particular, how our brains accomplish the incredible feat of constructing a three-dimensional reality using nothing but 2-D images from our eyes. A young artist and psychology researcher named Adelbert Ames, Jr. developed a series of illusions that help us understand how this process of constructing reality actually works. Sometimes we need to be fooled in order to gain understanding.
We'd like to acknowledge Dr. Phil Kellman from UCLA for his helpful discussions about the principles of spatial perception at play in these illusions https://kellmanlab.psych.ucla.edu/

America's first great science battle wasn't the space race or the atom bomb, it was fought between Thomas Jefferson, a French nobleman, and in the middle… a giant moose. Some people call Jefferson our only scientist-President, and T.J. himself said that "Nature intended me for the tranquil pursuits of science, by rendering them my supreme delight."
Here's the story of how Jefferson used science to help a young nation make its mark

If you tried to sum up the last 150 years or so in one image, a chart of exponential growth would be a good place to start. It shows that some things change faster over time. You could apply it to life expectancy. Or compound interest. Or any number of things. But especially population growth. Back in 1798, a guy named Thomas Malthus noticed that not everything grows this way. And this caused people to worry because they were sure it would lead to massive death and starvation and famine. But that didn’t happen, thanks to something called the Green Revolution and a guy named Norman Borlaug. As we face a future population of ten billion and a world impacted by climate change, how will we do a Green Revolution 2.0? #GatesPartner

The largest pterosaurs like Quetzalcoatlus were closer in size to airplanes than birds. No flying animal alive today comes close to their huge size. So did giant pterosaurs actually fly? I went to see the fossil bones of the largest pterosaur that ever lived so I could learn how these winged giants actually took to the skies.

If bees go, will they take us with them?

Bees, wild and domesticated, are in big trouble. Bee colonies are dying off at alarming rates, and the cause isn't clear. Pesticides, habitat loss, disease… there's a laundry list of likely culprits. We rely on these tiny pollinators for a majority of our fruits, veggies, and nuts… if they disappear, could we be next?
