Great Barrier Reef Suffered Worst Bleaching.

The Australian Research Council Centre of Excellence for Coral Reef Studies based at James Cook University has found that higher water temperatures have ravaged the Great Barrier Reef, causing the worst coral bleaching recorded by scientists. 67% of a 700km swath in the north of the reef lost its shallow-water corals over the past eight to nine months. The southern two-thirds of the reef escaped with minor damage, as it was protected from the rising sea temperatures because of cooler water from the Coral Sea.

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.

Halo of the Cat's Eye.
Image Credit & Copyright: Data: Michael Joner (West Mountain Observatory, BYU),
Romano Corradi (IAC), Hubble Legacy Archive - Processing: Robert Gendler. The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its haunting symmetries are seen in the very central region of this picture, processed to reveal an enormous but extremely faint halo of gaseous material, over three light-years across which surrounds the brighter, familiar planetary nebula. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. They are likely formed of material shrugged off during earlier active episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the outer filamentary portions of this halo to be 50,000 to 90,000 years old.

The current flag of Myanmar was adopted on 21 October 2010. The new flag was introduced along with implementing changes to the country's name, which were laid out in the 2008 Constitution. The design of the flag has three horizontal stripes of yellow, green and red with a five-pointed white star in the middle. The three colours of the stripes are meant to symbolise solidarity, peace and tranquility, and courage and decisiveness. The white star that symbolised the Union of Burma.

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.
