How we can detect pretty much anything - Hélène Morlon and Anna Papadopoulou

Explore how scientists use environmental DNA (eDNA) in a technique called DNA metabarcoding to find and track species. -- Scientists have been staking out a forest in Montana for an animal that’s notoriously tricky to find. Camera traps haven’t offered definitive evidence, and experts can’t identify its tracks with certainty. But within the past decades, researchers have developed methods that can detect even the most elusive species. So how does it work? Hélène Morlon & Anna Papadopoulou dig into DNA metabarcoding. Lesson by Hélène Morlon and Anna Papadopoulou, directed by Blok Magnaye.

The corpse flower could disturb your nighttime rest - Daniel Nickrent

Explore how the Rafflesia plant uses parasitic strategies to grow the world’s largest flower, and find out why it smells so bad. -- Deep inside the Sumatran rainforest, a carrion fly descends, guided by the scent of its favorite place to lay eggs: rotting animal carcasses. But when it lands, it isn’t on liquifying flesh, but instead on the world’s biggest, and perhaps strangest, flower— Rafflesia arnoldii. So, how does this giant flower grow? Daniel Nickrent explores the parasitic tendencies of the foul-smelling plant. Lesson by Daniel Nickrent, directed by Igor Ćorić, Artrake Studio.

The history of the Boston Tea Party - Ben Labaree

Discover what led American colonists in 1773 to toss tea into the Boston Harbor in what became known as the Boston Tea Party. -- Before the Revolutionary War, American colonists were taxed heavily for importing tea from Britain.

Ben Labaree gets into the nitty-gritty of that famous revolutionary act. Lesson by Ben Labaree, animation by Nick Fox-Gieg Animation.
