It was one of the strangest trials in Dutch history. The defendant in a 1947 case was an art forger who had counterfeited millions of dollars worth of paintings. But he wasn't arguing his innocence— in fact, his life depended on proving that he had committed fraud. Who was this artist, and why was he on trial for his life? Noah Charney investigates the notorious Han van Meegeren. [Directed by Hype CG, narrated by Addison Anderson, music by Gabriel Maia].

Dan Finkel shows how. [Directed by Charlotte Arene, narrated by Addison Anderson, music by Stephen LaRosa].

From Ancient Greece to the 20th century, Aristotle, Freud, and numerous other scholars were all looking for the same thing: eel testicles. Freshwater eels could be found in rivers across Europe, but no one had ever seen them mate and no researcher could find eel eggs or identify their reproductive organs. So how do eels reproduce, and where do they do it? Lucy Cooke digs into the ancient mystery. [Directed by Anton Bogaty, narrated by Adrian Dannatt, music by Jarrett Farkas].

The average 20-year-old knows between 27,000 and 52,000 different words. Spoken out loud, most of these words last less than a second. With every word, the brain has a quick decision to make: which of those thousands of options matches the signal? And about 98% of the time, the brain chooses the correct word. How is this possible? Gareth Gaskell digs into the complexities of speech comprehension. [Directed by Art Shot, narrated by Addison Anderson, music by Stephen LaRosa].
