The Boxer Rebellion

The Boxer Rebellion (1899-1901) was a popularly supported uprising of Chinese peasants against foreigners at a time when, during an economic depression, China was being forced to grant concessions to Western powers. The Righteous Fists of Harmony, or Boxers, opposed the political, economic, and religious encroachment of Westerners and killed thousands of Chinese Christians and Westerners before an international force quelled the attacks.

"The Blue Marble" Photograph Taken by Apollo 17 Crew (1972)

"The Blue Marble" is a famous photograph of Earth taken by the crew of the Apollo 17 spacecraft while traveling toward the Moon in 1972. So-titled because the Earth resembles a blue marble—accented by swirls of white clouds—the image is among the most widely distributed photographs in history. Depicting a fully lit Earth, the snapshot was originally taken "upside-down," with Antarctica on top, but was rotated before distribution. How did NASA update the image in 2005? More...

Armenia Earthquake Memorial Day (2015)

On December 7, 1988, a severe earthquake struck in Armenia, causing catastrophic damage to the entire country's infrastructure and virtually destroying the cities of Spitak, Leninakan (now Gyumri), Kirovakan (now Vanadzor), and Stepanavan.

Ebola Vaccine Effective in Mice

The Ebola virus, which causes severe hemorrhagic fever, has no cure and kills up to 90 percent of the people it infects. Though few people contract Ebola each year, and only around 1,200 people have died from it since it was first identified in 1976, there are concerns that it could be used by terrorists as a form of biological weapon. Existing vaccines against the virus degrade over time and therefore cannot be stockpiled for use in the event of such an attack. However, a new vaccine that does remain viable long-term has been developed and successfully conferred immunity to 80 percent of the mice tested. More...
