THESE SEA SLUGS CAN DO WHAT?!



Meet the solar powered sea slug. Scientists discovered two species of sea slugs that can detach their heads from their bodies and regrow and new body from just their heads. They do this to survive parasite attacks!

What If You Traveled to the Hell Planet?



We visit a lot of planets here on WHAT IF, but K2-141b is the most extreme one yet. Are you ready to jump on board this one-way space shuttle? If you’d rather stay safely Earthbound, I want you to take a look up at the night sky and find the constellation of Aquarius. Right there. Now imagine traveling 202 light-years in that direction, and that’s where you’d find the hell planet. What’s that stuff falling from the sky? Why is this planet so different from Earth? How did it get that name?

What If You Brought Modern Technology to the Middle Ages?



The Middle Ages, a time when you were more likely to die on the toilet than take a bath. And now you’re going there with an educational mission. It’s up to you now. Let’s show the Middle Ages how it’s done. Would you be tried as a witch? Could you cure all diseases? Or would you accidentally create a new pandemic? Would you be able to discover electricity? Will smallpox be cured? What are garderobes?
