    --

    In 1987, thousands of people gathered in Saudi Arabia for the annual Hajj pilgrimage.

  • What makes tuberculosis (TB) the world's most infectious killer? - Melvin Sanicas

    Learn why tuberculosis, TB, is the world’s most infectious disease and how medical advancements are improving treatment.

    Uploaded 27-06-19

    --

    In 2008, two 9,000-year old skeletons were found with their bones infected by an all too familiar bacterium. The ancient Greeks knew its effects as phthisis; the Incans called it chaky oncay; and today we call it tuberculosis, or TB. TB is still one of the world’s most infectious killers, causing more deaths than malaria or even HIV. How has it persisted for so long? Melvin Sanicas investigates.

  • How humanity developed a dependence on coffee - Jonathan Morris

    Trace the history of coffee, from its first known origins to its rise in popularity due to trade routes and cultivation.

    --

    One day around 850 CE, a goatherd observed that his goats started acting abnormally after nibbling on some berries. The herder tried them himself, and soon enough, he was just as hyper. As the story goes, this was humanity’s first run-in with coffee. So, how did coffee go from humble plant to one of the world's most consumed beverages? Jonathan Morris traces the history of this energizing elixir.

    Lesson by Jonathan Morris, directed by Harry Tennant.
