They're slippery. They're slithery. And while they totally look like underwater snakes, eels are, in fact, unique fish that can breathe through their skin and even survive out of water. James Prosek tracks the life journey of Eli the Anguilla eel as she (yes, she) travels her mysterious "backward" migration from the sea to fresh water and back again.

Trace the rise and fall of the powdered wig fashion craze, from King Louis XIII to the French Revolution in the 18th century.

--

Wigs date at least as far back as ancient Egypt, where well-regarded hairdressers crafted them into intricate styles. And under certain ancient Roman dynasties, women’s wigs became particularly ornate. Yet it wasn’t until Louis XIII unveiled a magnificent mane in the 17th century that big wigs truly began booming. Stephanie Honchell Smith details the rise and fall of the bewigged fashion craze.

Lesson by Stephanie Honchell Smith, directed by Patrick Smith.

Smuggling yourself aboard the rogue submarine was the easy part. Hacking into the nuclear missile launch override — a little harder. And you’ve got a problem: you don’t have the override code. You know you need the same numbers that were used to authorize the launch, but one wrong answer will lock you out. Can you figure out what numbers to enter to stop nuclear war? Alex Rosenthal shows how.

Uncover the oil industry’s decades-long campaign to discredit climate change science regarding the danger of fossil fuels.

--

Throughout the 1980s, oil industry reps discussed the dangers of burning fossil fuels, acknowledging the risk their product posed to the future of humanity. However, instead of warning the public or pivoting towards renewable energy sources, they doubled down on oil — and launched a decades-long campaign to discredit climate change science. Stephanie Honchell Smith digs into Big Oil's tactics.

Pods of killer whales inhabit the waters of every major ocean on Earth. Each family is able to survive thanks mainly to one member, its most knowledgeable hunter: the grandmother. These matriarchs can live 80 years or more and their expertise can mean the difference between life and death for their families. Darren Croft details the lives of killer whales and the dangers facing their survival.

Uploaded 07-10-21

So what happened to this African kingdom? Geoff Emberling details the rise and fall of the Kush empire.

Lesson by Geoff Emberling, directed by Carlos Rupit and Lizeth Rodríguez.

The origins of the cameras we use today were invented in the 19th century. Or were they? A millenia before, Arab scientist Alhazen was using the camera obscura to duplicate images, with Leonardo da Vinci following suit 500 years later and major innovations beginning in the 19th century. Eva Timothy tracks the trajectory from the most rudimentary cameras to the ubiquity of them today.

Examine the myth of the benevolent dictator, which is a leader who holds absolute power yet only uses it for the common good.

--

Under certain conditions, the idea of a dictator can sound appealing, like when a democracy isn’t functioning as it should due to corruption or political polarization. People may believe the solution is a "benevolent dictator"— a leader who only uses their absolute power for the common good. But can such a leader actually exist in today’s world? Stephanie Honchell Smith examines this common myth.
