In the above photograph, lightning strikes over the Puyehue volcano, over 500 miles south of Santiago, Chile. About 3,500 people in the nearby area have had to evacuate.

HISTORY: No more Plessy v. Ferguson

On this date, 119 years ago, Homer Plessy acknowledged he was colored and refused to move from a seat reserved for whites on a train in New Orleans.

Plessy was arrested and brought to trial in a case before the judge John Howard Ferguson. His case led to the U.S. Supreme Court's “separate but equal,” ruling which remained in place until 1954. In a stunning literal example of time healing wounds, two descendants of Plessy and Ferguson, Keith Plessy and Phoebe Ferguson, have come together to form a foundation, Plessy & Ferguson, to highlight historical moments in New Orleans’s struggle for racial equality.

The World Health Organization worries that time is running out to find the cause.
