But what started out as a celebration led to a worldwide health crisis: more than 2,000 cases of meningitis broke out, spreading across Saudi Arabia and the rest of the world. How did it spread so quickly and what makes meningitis so dangerous? Melvin Sanicas examines how the disease affects our bodies.

About once every century, a massive star somewhere in our galaxy runs out of fuel. No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova. The death of that star is the birth of a neutron star: one of the densest known objects in the universe. David Lunney explores what, exactly, a neutron star is. [Directed by JodyPrody, narrated by Addison Anderson, music by Jody Ghani Nordby].

He tried to make sense of human behavior by studying the shapes of stories — ditching straightforward chronologies and clear-cut fortunes.
