Portrait of Madame X

American painter John Singer Sargent, at one time the world's most famous and highly paid portrait painter, is best known for his portraits of American and English social celebrities. In 1884, before he had achieved acclaim, a scandal erupted when he exhibited Portrait of Madame X in Paris.

Where is the painting today? More...

Feast of the Martyrs of North America (2016)

The Feast of the North American Martyrs commemorates the death of eight priests who were killed by the Iroquois, enemies of the Huron Indians, with whom the priests had been working for 34 years. The eight who are remembered on this day are St. Rene Goupil (1608-1642), St. Isaac Jogues (1607-1646), St. John Lalonde (d. 1646), and their companions, French Jesuits who died in 1649.

World's First Malaria Vaccine Could Save Millions

For decades, scientists have worked to eradicate malaria, an infectious parasitic disease that kills more than a million people each year, but had little success developing an effective vaccine until now. Preliminary results of a phase 3 clinical trial for a vaccine known as RTS,S, or Mosquirix, suggest that it could cut the number of malaria cases in half. The trial is ongoing, but data from the first 6,000 children, all between 5 and 17 months of age, showed about a 50 percent reduction in malaria cases in the 12-month period following vaccination.
