Depressed? Do you have headaches, dizziness, cramps, difficulty breathing? From 300 BCE to the 1900s, if you answered yes to any of these questions and you had a uterus, a doctor would likely diagnose you with hysteria. So, where did this medical diagnosis come from? And why did it persist for so long? Mark S. Micale traces the history of the catch-all term. Lesson by Mark S. Micale, directed by Laura Jayne Hodkin.

Why did it take such a long time to find giant squids? - Anna Rothschild

Dive into the deep sea to find giant squids, and explore what scientists have learned about these mysterious creatures. -- In 1873, fishermen glimpsed what they thought was a shipwreck. But when they probed the mass, it moved— and huge, serpentine appendages soon besieged their boat. One fisherman took an axe to the animal, and it disappeared in a cloud of ink, leaving behind definitive evidence that giant squids were more than mythical monsters. So, what do we know about these creatures? Anna Rothschild investigates. Lesson by Anna Rothschild, directed by Vitalii Nebelskyi, and action creative agency.
