Could we survive the end of our Solar System? How about the end of the entire universe? Let's find out! 🤩

The Sun showers Earth with energy every second. But how can we keep some for later?

Solar panels turn sunlight into electricity we use right away. To save it for tomorrow or a rainy day, we need to trap it. One way to do this is with a Concentrated Solar Power plant, where thousands of mirrors bounce sunlight onto a tower of molten salt, heating it to over 500°C.
The salt stores the heat for hours and can release the energy again when it’s needed. And for even longer storage, we can turn sunlight into liquid hydrogen or ammonia.

We’re actually working on four short videos about renewable energy at the moment, created with support from @aha.bayern and @wissenschaftsjahr – just like this post. Stay tuned!

Viruses are nothing but a tiny bit of genetic material and a few proteins. No metabolism and no way to propel themselves. But they got even weirder when scientists found a completely new type of viruses: giant viruses, nicknamed “giruses”. And ever since we identified the first one in 2003, we've been finding them everywhere we look. But what makes them special is not just their size. It is that they are much more complex than we thought was possible for a virus.

Your cells have around 20,000 genes. A typical bacterium has a few thousand genes, while HIV or the flu has around 10. Generally, scientists think of life as a complex system, so below a certain complexity level, something may be closer to dead material rather than a living organism. However, giruses can have hundreds or even thousands of genes, blurring the line between living and dead things.

Unless the goal of the experiment # 837819 was to flood the entire third floor of the kurzgesagt labs, we think it’s safe to say the experiment failed. 😔

Dinosaurs’ bones alone aren't enough to tell us everything we'd like to know about them, how they behaved or even what exactly they looked like. However, modern technology can help us identify some features, like skin and feathers, from distinctive marks left on the bone. Studying these while also looking at today’s animals with similar features can be highly informative. It’s a similar story with color. Because we know what the feathers of living birds look like, and have a few exceedingly rare fossils with preserved remains of fuzzy feathers, we can glimpse the real colors of extinct dinosaurs. That's why, for instance, we know that tiny Sinosauropteryx had a striped tail while its tiny dino buddy Anchiornis huxleyi was white and black with gorgeous red feathers around its head.

Unfortunately, you won't explore the entire galaxy. And neither will the rest of the humanity. However, AI might! And it's already happening!

Could we power the whole world with just renewables?
Solar and wind power are cheap and basically infinite, but they are not always available when we need them. That’s why many countries still rely on fossil fuels.
But it doesn’t have to stay that way.
Hydropower and geothermal energy can help fill the gap, while clever storage solutions like pumped water, hydrogen fuel, and powerful batteries are helping us make clean energy last longer. If we combine renewables with the right tools, we could ditch fossil fuels for good!
