    Volcanic eruption explained - Steven Anderson

    Dig into the science of how new volcanoes form, and what causes their unpredictable eruptions. -- In February of 1942, Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield. However, the sound wasn’t coming from the sky. The source was a large, smoking crack emitting gas and ejecting rocks, and would come to be known as the volcano Paricutin. Where do new volcanoes like this come from, and what triggers their unpredictable eruption? Steven Anderson investigates. Lesson by Steven Anderson, directed by Cabong Studios.

    Why do humans have a third eyelid? - Dorsa Amir

    Discover how evolution and natural selection influence why the human body has vestigial organs— body parts that no longer serve their original purpose. -- You know that little pink thing nestled in the corner of your eye? It’s actually the remnant of a third eyelid. In humans, it’s vestigial, meaning it no longer serves its original purpose. There are several other vestigial structures in the human body, quietly riding along from one of our ancestor species to the next. But why have they stuck around for so long? Dorsa Amir investigates.

Malay Bera shares the Bengali tale of Kiranmala's quest. Lesson by Malay Bera, directed by Héloïse Dorsan-Rachet.
