A number of significant scientific events occurred in 2013, including the discovery of numerous Earthlike exoplanets, the development of viable lab-grown ears, teeth, livers and blood vessels, and the atmospheric entry of the most destructive meteor since 1908. The year also saw successful new treatments for diseases such as HIV, Usher syndrome and leukodystrophy, and a major expansion in the use and capabilities of technologies such as 3D printing and autonomous cars.

The United Nations designated 2013 the International Year of Water Cooperation.
