From today's featured article

The PlayStation is a home video game console developed and marketed by Sony Computer Entertainment. It was released in Japan on 3 December 1994, and most of the world in 1995. Sony began developing it after a failed venture with Nintendo to create a CD-ROM add-on in the early 1990s. The console was primarily designed by Ken Kutaragi and his team in Japan, while additional development was outsourced in the United Kingdom. An emphasis on 3D polygon graphics was placed at the forefront of the console's design. The PlayStation signalled Sony's rise to power in the video game industry. It received acclaim and sold strongly; in less than a decade, it became the first computer entertainment platform to ship more than 100 million units. Its use of compact discs heralded the game industry's transition from cartridges. The PlayStation's success led to a line of successors, beginning with the PlayStation 2 in 2000. (Full article...)

Today's featured picture

The mangosteen (Garcinia mangostana) is a tropical evergreen tree with edible fruit native to Maritime Southeast Asia, from the Malay Peninsula to Borneo. It is grown mainly in Southeast Asia, southwest India, and other tropical areas such as Colombia, Puerto Rico and Florida, where the tree has been introduced. The fruit is sweet and tangy, juicy, somewhat fibrous, with fluid-filled vesicles (like the flesh of citrus fruits), with an inedible, deep reddish-purple colored rind (exocarp) when ripe. In each fruit, the fragrant edible white flesh that surrounds each seed is the endocarp, the inner layer of the ovary, and is roughly the same shape and size as a tangerine, about 4 to 6 centimetres (1.5 to 2.5 inches) in diameter. This photograph, which was focus-stacked from 22 individual images, shows two mangosteens, one whole, and the other halved to expose the endocarp.
