Where HIV First Emerged.

This disease’s notoriety has been well established since its discovery 35 years ago. Perhaps we can now take a more objective view of its origin and how it spread to humans, as it can happen with any disease. The Ebola epidemic in central Africa was one such scenario.

Galaxy NGC 474: Cosmic Blender.
Image Credit & Copyright: P.-A. Duc (CEA, CFHT), Atlas 3D Collaboration. The multiple layers of emission appear strangely complex and unexpected given the relatively featureless appearance of NGC 474 elliptical galaxy. The cause of the shells is currently unknown, but possibly tidal tails related to debris left over from absorbing numerous small galaxies in the past billion years. Alternatively, the shells may be like ripples in a pond, where the ongoing collision with the spiral galaxy just above NGC 474 is causing density waves to ripple through the galactic giant. Regardless of the actual cause, the increasing consensus is that at least some elliptical galaxies have formed in the recent past and that the outer halos of most large galaxies are not really smooth but have complexities induced by frequent interactions with, and accretions of smaller nearby galaxies. NGC 474 spans about 250,000 light years and lies about 100 million light-years distant toward the constellation of the Fish (Pisces).

The Kachin people are a confederation of ethnic groups who inhabit the Kachin Hills in northern Burma's Kachin State and neighbouring Yunnan Province, China, and Arunachal Pradesh, India. About one million Kachin peoples live in the region. The term Kachin people is often used interchangeably with the main subset, called the Jingpo people in China. The Jingpho language common to many of the Kachin has a variety of dialects and is written with a Latin-based script created in the late nineteenth century.

The flag of Mongolia is a vertical tricolour with two reds at insides and a blue in the middle, with the Soyombo symbol defacing the left red stripe. The blue stripe is described as the eternal blue sky and the red stripes symbolise thriving forever. The Soyombo symbol is a geometric abstraction that represents fire, sun, moon, earth, water, and a round shape as dualist aspect. The current flag was adopted on February 12, 1992, after the transition of Mongolia to a liberal democracy.

The Elgin Marbles, also known as the Parthenon Marbles, are a collection of Classical Greek marble sculptures made under the supervision of the architect and sculptor Phidias and his assistants in c. 447 to 438 BC; originally part of the temple of the Parthenon and other buildings on the Acropolis of Athens. From 1801 to 1812, agents of Thomas Bruce, 7th Earl of Elgin removed about half of the surviving sculptures of the Parthenon, 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.
