The Ring-tailed Lemur is a relatively large prosimian, a lemur belonging to the family Lemuridae. Ring-tailed Lemurs are the only species within the genus Lemur and are found only on the island of Madagascar. Although threatened by habitat destruction in their native forests, Ring-tailed Lemurs are the most populous lemurs in zoos worldwide; in part because they reproduce readily in captivity.

A stinger is an organ or body part found in various animals that usually delivers some kind of venom. Animals with stingers include scorpions, bees and wasps (as shown here).

The stinger, which may be barbed so as to lodge in the flesh of the victim, is typically located near the tail. For creatures such as jellyfish, stinger can refer to the tentacles that carry cnidocytes to capture and paralyze prey.

Peace and quiet is a quality often missing in the urban environment. Those who travel to remote, rural areas often notice the striking difference in the noise level between the cities and the countryside, although in practice the ambient noise level is still higher than the near absolute quiet found in an anechoic chamber.

This view of Lake Mapourika in New Zealand captures the essence of tranquillity.

A mackerel sky is an indicator of moisture and instability at high levels. If the lower atmosphere is stable and no moist air moves in, the weather will most likely remain dry. However, moisture at lower levels combined with temperature instability can lead to spectacular thunderstorms should the rising moist air reach this layer. In weather lore, a mackerel sky portends changeable weather.

City Hall in London is the headquarters of the Greater London Authority, and stands on the south bank of the River Thames near to Tower Bridge. The building was designed by Foster and Partners and opened in July 2002. It has an unusual bulbous shape, intended to reduce the building's surface area and thus improve energy efficiency. City Hall was constructed on a site formerly occupied by wharves serving the Pool of London (a stretch of the River Thames).

U.S. F/A-18 Hornet breaking the sound barrier. In aerodynamics, the sound barrier is the apparent physical boundary stopping large objects becoming supersonic. When an aircraft breaks the sound barrier, an unusual cloud sometimes forms. A drop in pressure, in this case due to shock wave formation, causes water droplets to condense and form the cloud.

Hot air balloons are the oldest successful human flight technology, dating back to the Montgolfier brothers' invention in Annonay, France in 1783. The first manned flight was made in Paris by Pilâtre de Rozier and the Marquis d'Arlandes. Unmanned hot air balloons are mentioned in Chinese history. Chu-ko Kung-ming (諸葛 孔明) in the three kingdoms era used airborne lanterns for military signalling.

Art Nouveau ("new art" in French) is an art and design style that peaked in popularity at the beginning of the 20th century in Europe and the United States. Unlike most art movements, Art Nouveau bridges the divide between fine art and applied art (illustration, decorative arts, crafts and architecture).

Dancel (1898) by Alfons Mucha with its strong, flowing, organic lines, is typical of the style.

Ansel Adams was one of the masters of landscape photography. Born in San Francisco in 1902, he is famous for his black & white photographs of the western United States and national parks, most especially Yosemite. Adams was a co-founder of Group f/64, who pioneered the use of a camera's smallest aperture to capture a scene with maximum sharpness and depth of field — a technique known as 'Realism' or straight photography.

The movement and the flow of chemicals into the stomach are controlled by both the autonomic nervous system and by various digestive system hormones. Gastric acid is the main secretion of the stomach, characterised by H₂O, hydrochloric acid and several enzymes (mainly pepsinogen). Gastic acid is produced by the parietal cell (wall cell) of the gastric mucosa.

During a winch launch, a glider is pulled by a wire cable like a kite, raising it to an altitude of around 1000 ft (300 m). For the rest of its flight, being un-powered, the heavier-than-air aeroplane is always falling. However a pilot can gain height by circling within a strong thermal — a column of air that is rising at a faster rate than the plane is falling. On a good day, an experienced pilot can travel hundreds of miles before landing.

The Chicago based, German architect Helmut Jahn is best known for his efficiently designed modernist office blocks. Whilst many of these glass and steel buildings don't stand out from the crowd, some of his most eye-catching projects, such as the Sony Center in Berlin, with its tent-like roof covering the central Forum, border on post-modernism.

The insides of a typical keydrive. With the plastic clamshell case removed, we can see that the keydrive consists of only two significant components. The first is the flash memory chip (item 4). The second (item 2) is a device which implements the USB networking and mass-storage interface.
