Human history is really the story of the energy we’ve learned to control.

Hey there! So, you know, the human immune system is this super complex thing – honestly, it’s probably the most complicated biological system we know, right after the human brain. And yet, most of us never really learn what it is or how it actually works.

Sometimes the world can feel a bit… well, ordinary, right? We’ve checked out pretty much everywhere – remote islands, the Arctic, deep jungles. But there’s still this one amazing place left to explore. It’s like a really wet and super dangerous desert, filled with mysterious creatures that live in total darkness. That place is the deep sea. So, let’s take a look down there!

If you somehow spotted a wormhole in reality, here’s what it would probably look like:

So, what’s the real deal with the universe? What’s its true nature? We humans have always tried to figure this out by making up stories to describe the world around us. We test these stories, see if they hold up, and keep the parts that work, tossing out the bits that don’t.

Cancer feels really mysterious and, well, creepy. As folks have tried to figure out how to beat it, they stumbled upon something in biology that still doesn’t make sense: Turns out, really big animals seem almost immune to cancer. This is totally backwards from what you’d expect. You’d think the bigger something is, the more cancer it should get.

Imagine this: NASA announces today they found aliens! They found bacteria on Mars, weird alien fish in the oceans of Europa, and ancient alien ruins on Titan. Sounds amazing, right?

Hey there. You know, everyone feels lonely now and then. It hits when you’ve got nobody to sit with at lunch, or maybe you’ve just moved somewhere new and don’t know a soul. Or perhaps nobody’s free on the weekend when you are.
