In November 1986, Australian miners climbed Lunatic Hill and bored 20 meters into the Earth. They were rewarded with a fist-sized, record breaking gemstone, which they named the Hailey's Comet opal. Thanks to a characteristic called "play of color," no two opals look the same. So what causes these vibrant displays? Jeff Dekofsky digs into the rock's shimmering, dancing displays of light.

Every time you breathe, air travels down the trachea, through a series of channels, and then reaches little clusters of air sacs in the lungs. These tiny sacs facilitate a crucial exchange: allowing oxygen from the air we breathe into the bloodstream and clearing out carbon dioxide. Pneumonia wreaks havoc on this exchange system. Eve Gaus and Vanessa Ruiz detail how pneumonia attacks the lungs. [Directed by Artrake Studio, narrated by Alexandra Panzer].
