Uploaded 10-02-15

Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby buildings. Katerina Kaouri details how scientists use math to predict sonic booms' paths in the atmosphere, where they will land, and how loud they will be.

Lesson by Katerina Kaouri, animation by Anton Bogaty.

In the 1600s, an expansive autonomous settlement called Palmares reached its height in Brazil. It was founded and led by people escaping from slavery, also called maroons. It was one of the world’s largest maroon communities, its population reaching beyond 10,000— and its citizens were at constant war with colonial forces. Marc Adam Hertzman & Flavio dos Santos Gomes tell the story of Palmares.

What shape are your cells? Squishy cylinders? Jagged zig-zags? You might not spend a lot of time thinking about the bodies of these building blocks, but microscopically, small variations can have huge consequences. And while some adaptations change these shapes for the better, others can spark debilitating complications. Amber Yates dives into the science of the malignant sickle-cell mutation.
