From today's featured articleNihonium is a synthetic chemical element with symbol Nh and atomic number 113. It is extremely radioactive; its most stable known isotope, nihonium-286, has a half-life of about 10 seconds. In the periodic table, nihonium is a transactinide element at the intersection of period 7 and group 13. Its creation was reported in 2003 by a Russian–American collaboration at the Joint Institute for Nuclear Research in Dubna, Russia, and in 2004 by a team of Japanese scientists at Riken in Wakō, Japan. The discoveries were confirmed by independent teams working in the United States, Germany, Sweden, and China. In 2016 the element was officially recognised and naming rights were assigned to Riken, as they were judged to have been first to observe it. The name, approved in the same year (announcement pictured), derives from a Japanese word for Japan, Nihon. Few details are known about nihonium, as it has only been formed in very small amounts that decay away within seconds. (Full article...) Did you know...

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. Drought and a failure to apply dryland farming methods to prevent wind erosion caused the phenomenon. The drought came in three waves, 1934, 1936, and 1939–1940, but some regions of the high plains experienced drought conditions for as many as eight years. This photograph, titled Broke, baby sick, and car trouble!, was taken by Dorothea Lange in 1937 and depicts a Missouri migrant family's jalopy stuck near Tracy, California. Photograph: Dorothea Lange. Restoration: Adam Cuerden.
