Superager Brains Shrink More Slowly Than Peers’ Brains.

In the April 2017 issue of the Journal of the American Medical Association, an article entitled “Rates of Cortical Atrophy in Adults 80 Years and Older With Superior vs Average Episodic Memory” by Amanda H. Cook, Jaiahre Sridhar, Daniel Ohm, et al., from Northwestern University, Chicago, Illinois, was published. The Paper’s Abstract described the research as follows: “SuperAgers” have previously been defined as adults 80 years and older with episodic memory ability at least as good as that of average middle-age adults. They have a significantly thicker brain cortex than their same-age peers with average-for-age memory, which is unusual as age-related cortical atrophy is considered “normal” and often associated with cognitive decline in non-demented older adults. SuperAgers may experience similar atrophy rates as their cognitively average peers, but start with larger brain volumes, or they may resist age-related cortical atrophy. To examine the latter possibility, we quantitated rates of cortical volume change over 18 months in SuperAgers and cognitively average elderly adults.”

The Guna, known as Kuna prior to an orthographic reform in 2010, and historically as Cuna, are an indigenous people of Panama and Colombia. In the Kuna language, they call themselves Dule or Tule, meaning "people," and the name of the language in Kuna is Dulegaya, literally "people-mouth." Most Gunas live on small islands off the coast of the comarca of Kuna Yala known as the San Blas Islands. Each community has its own political organization, led by a saila, who is traditionally both the political and religious leader of the community; he memorizes songs which relate the sacred history of the people and transmits them to the people. Traditionally, Guna families are matrilinear, with the groom moving to become part of the bride's family and taking the last name of the bride as well.

Jupiter in Ultraviolet from Hubble.
Image Credit: NASA, ESA, Hubble; Processing & License: Judy Schmidt. Jupiter looks a bit different in the ultraviolet light. The colours of Jupiter go beyond the normal human visual range to include both ultraviolet and infrared light. Featured from 2017, Jupiter appears different partly because the amount of sunlight reflected back is distinct, giving differing cloud heights and latitudes discrepant brightnesses. In the near UV, Jupiter's poles appear relatively dark, as does its Great Red Spot and a smaller (optically) white oval to the right. The String of Pearl storms farther to the right, however, is brightest in near ultraviolet, and so here appear pink. Jupiter's largest moon Ganymede appears on the upper left.

The flag of Mozambique was adopted on May 1, 1983. It includes the image of an AK-47 with a bayonet attached to the barrel. It is one of three national flags among UN member states that features a firearm, along with those of Guatemala and Haiti. Green stands for the riches of the land, the white fimbriations signify peace, black represents the African continent, yellow symbolises the country's minerals, and red represents the struggle for independence. The rifle stands for defence and vigilance, the open book symbolises the importance of education, the hoe represents the country's agriculture, and the star symbolises Marxism and internationalism.

The Elgin Marbles are a collection of Classical Greek marble sculptures made under the supervision of Phidias and his assistants in c. 447 to 438 BC; originally part of the temple of the Parthenon. From 1801 to 1812, agents of Thomas Bruce, 7th Earl of Elgin removed about half of the surviving sculptures and transported them to Britain. The half not removed is now displayed in the Acropolis Museum. In Britain, the acquisition of the collection was not supported by some, and the Earl's actions was likened to vandalism. Following a public debate in Parliament and its subsequent exoneration of Elgin, he sold the Marbles to the British government in 1816. They were then passed to the British Museum, where they are now on display in the purpose-built Duveen Gallery.
