Take a peek beneath the ocean’s covers to discover the surprisingly inventive ways marine animals have sex.

Uploaded 23-11-21

--

On a reef in the Pacific Ocean, 17,000 camouflage groupers dart about in the cloudy water. It is, in fact, an underwater orgy— turned feeding frenzy. An orgy might seem like a rather flamboyant way to breed, but sex in the sea is a surprisingly inventive affair. So what other sneaky escapades are happening under the sea? Luka Seamus Wright offers a peek beneath the ocean’s covers.

Lesson by Luka Seamus Wright, directed by Michelle O'Connell and Lisa Vertudaches.

Follow alcohol on its journey through the body to find out how it causes drunkenness and why it affects people differently.

Uploaded 09-04-20

Ethanol: this molecule, made of little more than a few carbon atoms, is responsible for drunkenness. Often simply referred to as alcohol, ethanol is the active ingredient in alcoholic beverages. So how exactly does it cause drunkenness, and why does it have dramatically different effects on different people? Judy Grisel explores alcohol's journey through the body.

Lesson by Judy Grisel, directed by Anton Bogaty.

Dig into the evolutionary strategy of brood parasitism, where one animal tricks another into rearing its young.

Uploaded 14-12-21

--

A mother honeyguide has placed its chick into a bee-eater’s nest— puncturing all the other eggs in the nest and leaving only its own hatching alive. Over the following weeks, the host parents devotedly care for the hatchling whose mother murdered their offspring. This is brood parasitism, a phenomenon which is especially well-known among birds. Steve Rothstein digs into the evolutionary strategy.

Uploaded 12-11-24

--

When an Armenian resistance movement began to form in the 19th century, Sultan Abdul Hamid II took decisive action. He led the Hamidian Massacres— a relentless campaign of violence that killed over 150,000 Armenians. These massacres were the culmination of centuries of oppression, yet they were only the beginning of an even greater tragedy. Ümit Kurt uncovers the history of the Armenian Genocide.

Lesson by Ümit Kurt, directed by Héloïse Dorsan-Rachet.

The classical physics that we encounter in our everyday, macroscopic world is very different from the quantum physics that governs systems on a much smaller scale (like atoms). One great example of quantum physics’ weirdness can be shown in the Schrödinger's cat thought experiment. Josh Samani walks us through this experiment in quantum entanglement.

Trace the life cycle of a pair of denim jeans, and discover the labor and environmental costs of this fashion staple.

Uploaded 30-11-21

--

The first pairs of jeans were designed for durability; denim was constructed as a sturdy weave worn by sailors and miners. But over the course of the 20th century, as the demand for jeans has gone up, their durability has gone down. Today, most pairs last no longer than a year. And each new pair you buy has a much higher cost than you might think. Madhavi Venkatesan traces the life cycle of jeans.

Lesson by Madhavi Venkatesan, directed by Sofia Pashaei.

In many parts of the world heat waves are happening more often with greater intensity and for longer durations. By 2050, Earth’s mid-latitudes could be experiencing extreme heat between 90 and 180 days a year, with tropical regions enduring even more. So how hot is too hot, and what can people do to handle the heat? Carolyn Beans digs into how heat waves affect your body.
