Where do Tarsiers life?
Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. Although the group was once more widespread, all the species living today are found in the islands of Southeast Asia.
They are primarily insectivorous, and catch insects by jumping at them. They are also known to prey on small vertebrates, such as birds, snakes, lizards, and bats.[5] As they jump from tree to tree, tarsiers can catch even birds in motion.
Gestation takes about six months, and tarsiers give birth to single offspring. Young tarsiers are born furred, and with open eyes, and are able to climb within a day of birth. They reach sexual maturity after one year. Adults live in pairs, with a home range of around one hectare.
Fossils of tarsiers and tarsiiform primates are found in Asia, Europe, and North America, and there are disputed fossils from Africa, but extant tarsiers are restricted to several Southeast Asian islands including the Philippines, Sulawesi, Borneo, and Sumatra. They also have the longest continuous fossil record of any primate genus, and the fossil record indicates that their dentition has not changed much, except in size, in the past 45 million years.

What is a Microcredit?
Microcredit is the extension of very small loans (microloans) to the unemployed, to poor entrepreneurs and to others living in poverty. These individuals lack collateral, steady employment and a verifiable credit history and therefore cannot meet even the most minimal qualifications to gain access to traditional credit. Microcredit is a part of microfinance, which is the provision of a wider range of financial services to the very poor.
Microcredit is a financial innovation that is generally considered to have originated with the Grameen Bank in Bangladesh. In that country, it has successfully enabled extremely impoverished people to engage in self-employment projects that allow them to generate an income and, in many cases, begin to build wealth and exit poverty. Due to the success of microcredit, many in the traditional banking industry have begun to realize that these microcredit borrowers should more correctly be categorized as pre-bankable; thus, microcredit is increasingly gaining credibility in the mainstream finance industry, and many traditional large finance organizations are contemplating microcredit projects as a source of future growth, even though almost everyone in larger development organizations discounted the likelihood of success of microcredit when it was begun. The United Nations declared 2005 the International Year of Microcredit.

Where is the largest single-dish telescope in the world?
The Arecibo Observatory is a very sensitive radio telescope located approximately 9 miles (14 km) south-southwest from the town of Arecibo in Puerto Rico. It is operated by Cornell University under cooperative agreement with the National Science Foundation. The observatory works as the National Astronomy and Ionosphere Center (NAIC) although both names are officially used to refer to it. NAIC more properly refers to the organization that runs both the observatory and associated offices at Cornell University.
The observatory's 305 m radio telescope is the largest single-aperture telescope (cf. multiple aperture telescope) ever constructed. It carries out three major areas of research: radio astronomy, aeronomy (using both the 305 m telescope and the observatory's lidar facility), and radar astronomy observations of solar system objects. Usage of the telescope is gained by submitting proposals to the observatory, which are evaluated by an independent board of referees.
The telescope is visually distinctive and has been used in the filming of notable motion picture and television productions: as the villain's antenna in the James Bond movie GoldenEye, as itself in the film Contact and in the 'X-Files' episode 'Little Green Men'. The telescope received additional international recognition in 1999 when it began to collect data for the SETI@home project.

The worlds largest food fight: La Tomatina
a Tomatina is a food fight festival held on the last Wednesday of August each year in the town of Buñol in the Valencia region of Spain. Tens of thousands of participants come from all over the world to fight in a brutal battle where more than one hundred metric tons of over-ripe tomatoes are thrown in the streets.
The week-long festival features music, parades, dancing, and fireworks. On the night before the tomato fight, participants of the festival compete in a paella cooking contest.It is tradition for the women to wear all white and the men to wear nothing. This festival started in 1952. Some do not come out alive in this festival.
Approximately 20,000–40,000 tourists come to the tomato fight, multiplying by several times Buñol's normal population of slightly over 9,000. There is limited accommodation for people who come to La Tomatina, and thus many participants stay in Valencia and travel by bus or train to Buñol, about 38 km outside the city. In preparation for the dirty mess that will ensue, shopkeepers use huge plastic covers on their storefronts in order to protect them from the carnage.

Do you know the secret of the mars face?
Cydonia Mensae is an albedo feature (region) on the planet Mars. It lies in the planet's northern hemisphere in a transitional zone between the heavily cratered regions to the South, and relatively smooth plains to the North. Some planetologists believe that the northern plains may once have been ocean beds and that Cydonia may have been a coastal zone (though this is still uncertain). Cydonia is covered in numerous mesas, some of which have attracted both scientific and popular attention.
Eighteen images of the Cydonia Mensae region on Mars were taken by the Viking 1 and Viking 2 orbiters. Of the seven good images, the lighting and time at which two pairs of images were taken are so close as to reduce the number to five distinct images. In one of the images taken by Viking 1 on July 25, 1976, one of the Cydonian mesas had the appearance of a humanoid 'Face on Mars'. When the image was originally acquired, Viking chief scientist Gerry Soffen dismissed the 'face' as a trick of light and shadow. However, a second image, also shows the 'Face' and was acquired 35 Viking orbits later at a different 'sun-angle'. This latter discovery was made independently by two computer engineers at NASA's Goddard Space Flight Center, Vincent DiPietro and Gregory Molenaar, who discovered the two misfiled images, while searching through NASA archives.
The occurrence of an object on Mars with a seemingly human face caught the attention of individuals and organisations interested in extraterrestrial intelligence and visitations to Earth, and the images were published in this context in 1977. Some commentators, most notably Richard Hoagland, believe the 'Face' to be evidence of a long-lost Martian civilization along with other features they believe are present, such as apparent pyramids, which they argue are part of a ruined city. Image analysis of the original Viking images led a few researchers to suggest that the features of the 'Face' might not be an accidental consequence of viewing conditions.

Which is the largest machine in the world?
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator, intended to collide opposing particle beams, protons at an energy of 7 TeV/particle or lead nuclei at 574 TeV/particle.
The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics, including the existence of the hypothesised Higgs boson and of the large family of new particles predicted by supersymmetry. It lies in a tunnel 27 kilometres (17 mi) in circumference, as much as 175 metres (570 ft) beneath the Franco-Swiss border near Geneva, Switzerland. It is funded by and built in collaboration with over 10,000 scientists and engineers from over 100 countries as well as hundreds of universities and laboratories.
On 10 September 2008, the proton beams were successfully circulated in the main ring of the LHC for the first time. On 19 September 2008, the operations were halted due to a serious fault between two superconducting bending magnets. Due to the resulting damage, the LHC will not be operational again before July 2009.

What is the Marre Man? The largest known geoglyph?
The Marree Man, or Stuart's Giant is a geoglyph discovered by air on 26 June 1998. It appears to depict an indigenous Australian man, most likely of the Pitjantjatjara tribe, hunting birds or wallabies with a throwing stick. It lies on a plateau at Finnis Springs 60 km west of the township of Marree in central South Australia. It is just outside of the 200,000 square kilometre Woomera Prohibited Area. The figure is 4.2 km tall with a circumference of 15–28 km. It is the largest known geoglyph in the world and is estimated to have taken between four and eight weeks to create, but despite this its origins are a mystery, with not a single witness to any part of the expansive operation. The name 'Stuart's Giant' was given in an anonymous press releases, after John McDouall Stuart.

The longest bridge in the world: Bang Na Expressway
The Bang Na Expressway is a 54 km (33.5 mi) long six-lane elevated highway in Bangkok, Thailand. It is a toll road that is part of the Bang Na-Trat highway and signed as National Highway 34.
The highway is elevated onto a viaduct (a bridge with many spans) that has an average span length of 42 meters (138 feet). It is a 27-meter (89-foot) wide box girder bridge and was completed in March 2000. It took 1,800,000 cubic meters (2,350,000 cubic yards) of concrete to build the bridge. The structure was built using a design-build contracting method and was designed by Jean Muller International.
There are two toll plazas on the elevated structure where the structure must widen to accommodate twelve lanes.
It is the longest bridge in the world, but is excluded on some lists since it does not cross a body of water.

The longest stairways
The longest stairway is listed by Guinness Book of Records as the service stairway for the Niesenbahn funicular railway near Spiez, Switzerland, with 11,674 steps and a height of 1669 m (5476 ft). The stairs are strictly employee-only.
A flight of 7,200 steps (including inner temple Steps), with 6,293 Official Mountain Walkway Steps, leads up the East Peak of Mount Tai in China.
The Ha'ikū Stairs, on the island of Oʻahu, Hawaiʻi, are approximately 4,000 steps which climb nearly 1/2 of a mile. Originally used to access longwire radio radio antennas which were strung high above the Haʻikū Valley, between Honolulu and Kāneʻohe, they are currently closed to hikers.
The Flørli stairs, in Lysefjorden, Norway, have 4,444 wooden steps which climb from sea level to 740 meters. It is a maintenance stairway for the water pipeline to the old Flørli hydro plant. The hydro plant is now closed down, and the stairs are open to the public. The stairway is claimed to be the longest wooden stairway in the world.
