Obverse of the half dollar
Obverse of the half dollar

The Wisconsin Territorial Centennial half dollar was designed by David Parsons and Benjamin Hawkins and minted by the United States Bureau of the Mint in 1936. The obverse (pictured) depicts a pick axe and lead ore, referring to the lead mining in early Wisconsin; the reverse depicts a badger and the territorial seal. Organizers of the territorial centennial celebration sought a commemorative half dollar as a fundraiser; newly issued United States commemorative coins at this time found a ready market from collectors and speculators. Accordingly, legislation was introduced by Senator Robert M. La Follette Jr., which passed Congress without opposition. When initial designs by Parsons were rejected by the Commission of Fine Arts, Hawkins was hired. He executed the designs, though Parsons was also given credit. A total of 25,000 pieces were coined for public sale in July 1936. Sales were weak and the coins were vended by the Wisconsin Historical Society until the late 1950s. The coins catalog for up to $250. (Full article...)

The 2013 Women's Cricket World Cup squads consisted of 120 players from 8 national women's cricket teams. Organised by the International Cricket Council (ICC), the 2013 Women's Cricket World Cup, held in India, was the tenth edition of the competition. Australia won the tournament for the sixth time, defeating the West Indies by 114 runs in the final (player of the match Jess Duffin, then known as Cameron, pictured). Each team selected a squad of 15 players which was finalised by 24 January 2013, and any changes to that squad due to illness or injury had to be requested in writing, and approved by the ICC's Event Technical Committee. England's captain, Charlotte Edwards, appeared in the tournament for the fifth successive time, the most of any player at the 2013 competition, while India's captain, Mithali Raj, made her fourth successive appearance.

Schematic representation of the human genome

The human genome is the complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in small DNA molecules found within mitochondria. This includes both protein-coding DNA sequences and various types of DNA that does not encode proteins. This schematic representation of the human diploid karyotype shows the organization of the human genome into chromosomes, as well as annotated bands and sub-bands as seen on G banding. The diagram shows both the female (XX) and male (XY) versions of the 23rd chromosome pair. Chromosomal changes during the cell cycle are displayed at the top center. The human mitochondrial genome is shown to scale at the bottom left.
