Embryonic stem cell

1981: Embryonic stem cells (ES cells) were independently first derived from mouse embryos by two groups.  Martin Evans and Matthew Kaufman from the Department of Genetics, University of Cambridge published first in July, revealing a new technique for culturing the mouse embryos in the uterus to allow for an increase in cell number, allowing for the derivation of ES cells from these embryos.[43] Gail R. Martin, from the Department of Anatomy, University of California, San Francisco, published her paper in December and coined the term “Embryonic Stem Cell”.[44] She showed that embryos could be cultured in vitro and that ES cells could be derived from these embryos.
1989: Mario R. Cappechi, Martin J. Evans, and Oliver Smithies publish their research which details their isolation and genetic modifications of embryonic stem cells, creating the first "knockout mice".[45] In creating knockout mice, this publication provided scientists with an entirely new way to study disease.
1998: A paper titled "Embryonic Stem Cell Lines Derived From Human Blastocysts" is published by a team from the University of Wisconsin, Madison. The researchers behind this study not only create the first embryonic stem cells, but recognize their pluripotency, as well as their capacity for self-renewal. The abstract of the paper notes the significance of the discovery with regards to the fields of developmental biology and drug discovery.[46]
2001: President George W. Bush allows federal funding to support research on roughly 60—at this time, already existing—lines of embryonic stem cells. Seeing as the limited lines that Bush allowed research on had already been established, this law supported embryonic stem cell research without raising any ethical questions that could arise with the creation of new lines under federal budget.[47]
2006: Japanese scientists Shinya Yamanaka and Kazutoshi Takashi publish a paper describing the induction of pluripotent stem cells from cultures of adult mouse fibroblasts. Induced pluripotent stem cells (iPSCs) are a huge discovery, as they are seemingly identical to embryonic stem cells and could be used without sparking the same moral controversy.[48]
January, 2009: The US Food and Drug Administration (FDA) provides approval for Geron Corporation's phase I trial of their human embryonic stem cell-derived treatment for spinal cord injuries. The announcement was met with excitement from the scientific community, but also with wariness from stem cell opposers. The treatment cells were, however, derived from the cell lines approved under George W. Bush's ESC policy.[49]
March, 2009: Executive Order 13505 is signed by President Barack Obama, removing the restrictions put in place on federal funding for human stem cells by the previous presidential administration. This would allow the National Institutes of Health (NIH) to provide funding for hESC research. The document also states that the NIH must provide revised federal funding guidelines within 120 days of the order's signing.[50]

Question: When were embryonic stem cells first used in research?
Hegemony

Hegemony (UK: /hɪˈɡɛməni, hɪˈdʒɛməni/, US: /hɪˈdʒɛməni/ (pronunciation) or /ˈhɛdʒəˌmoʊni/) is the political, economic, or military predominance or control of one state over others.[1][2][3][4] In ancient Greece (8th century BC – 6th century AD), hegemony denoted the politico-military dominance of a city-state over other city-states.[5] The dominant state is known as the hegemon.[6]

Question: What is hegemony?

IP address

Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number.[2] However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was developed in 1995,[3] and standardized in December 1998.[4] In July 2017, a final definition of the protocol was published.[5] IPv6 deployment has been ongoing since the mid-2000s.

Question: When was the IP address concept first developed?

Holyoke Street Railway

Operated by the Holyoke Street Railway Company, abbreviated on livery as the Hly. St. Ry. Co., the streetcar system begin operation on September 24, 1884, consolidated with the Amherst and Sunderland Street Railway in 1907, and ceased operations as a streetcar operator in 1937.[5] Regular bus operations began in 1921, and soon after the incorporation of the Pioneer Valley Transit Authority in 1977, the company began serving as a contract operator. This service continued until 1987, when a dispute between labor and management led regular bus service to an abrupt end, with would-be passengers still waiting at stops, on July 1, 1987.[2][1]:611 After four years of inactivity and with a municipal school bus contract failing to pass negotiations, the company liquidated its assets and had dissolved by 1991.[3][6]

Question: What years did the Holyoke Street Railway operate?

Honduras

Honduras spans about 112,492km2 (43,433sqmi) and has a population exceeding 9 million.[2][3] Its northern portions are part of the Western Caribbean Zone, as reflected in the area's demographics and culture. Honduras is known for its rich natural resources, including minerals, coffee, tropical fruit, and sugar cane, as well as for its growing textiles industry, which serves the international market.

Question: How large is Honduras?

Diamond type

Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities. Diamonds are separated into four types: TypeIa, TypeIb, TypeIIa, and TypeIIb. The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect.[1]

Question: What types of diamonds are there?
First French Empire

Following his retreat from Russia, Napoleon continued to retreat, this time from Germany. After the loss of Spain, reconquered by an allied army led by Wellington, the rising in the Netherlands preliminary to the invasion and the manifesto of Frankfort (1 December 1813)[14] which proclaimed it, he had to fall back upon the frontiers of 1795; and then later was driven yet farther back upon those of 1792—despite the brilliant campaign of 1814 against the invaders. Paris capitulated on 30 March 1814, and the Delenda Carthago, pronounced against Britain, was spoken of Napoleon. The Empire briefly fell with Napoleon's abdication at Fontainebleau on 11 April 1814.

Question: Why did Napoleon empire fall?

History of Lithuania

On February 16, 1918, Lithuania was re-established as a democratic state. It remained independent until the outset of World War II, when it was occupied by the Soviet Union under the terms of the Molotov–Ribbentrop Pact. Following a brief occupation by Nazi Germany after the Nazis waged war on the Soviet Union, Lithuania was again absorbed into the Soviet Union for nearly 50 years. In 1990–1991, Lithuania restored its sovereignty with the Act of the Re-Establishment of the State of Lithuania. Lithuania joined the NATO alliance in 2004 and the European Union as part of its enlargement in 2004.

Question: When was Lithuania founded?

History of Malaysia

After reviewing the Cobbold Commission's findings, the British government appointed the Landsdowne Commission to draft a constitution for Malaysia. The eventual constitution was essentially the same as the 1957 constitution, albeit with some rewording; for instance, giving recognition to the special position of the natives of the Borneo States. North Borneo, Sarawak and Singapore were also granted some autonomy unavailable to the states of Malaya. After negotiations in July 1963, it was agreed that Malaysia would come into being on 31 August 1963, consisting of Malaya, North Borneo, Sarawak and Singapore. The date was to coincide with the independence day of Malaya and the British giving self-rule to Sarawak and North Borneo. However, Indonesia and the Philippines strenuously objected to this development, with Indonesia claiming Malaysia represented a form of "neocolonialism" and the Philippines claiming North Borneo as its territory. The opposition from the Indonesian government led by Sukarno and attempts by the Sarawak United People's Party delayed the formation of Malaysia.[103] Due to these factors, an eight-member UN team was formed to re-ascertain whether North Borneo and Sarawak truly wanted to join Malaysia.[104][105] Malaysia formally came into being on 16 September 1963, consisting of Malaya, North Borneo, Sarawak, and Singapore. In 1963 the total population of Malaysia was about 10 million.

Question: When was Malaysia founded?
Amnesia

Amnesia is a deficit in memory caused by brain damage, disease, or psychological trauma.[1] Amnesia can also be caused temporarily by the use of various sedatives and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that was caused.[2] There are two main types of amnesia: retrograde amnesia and anterograde amnesia. Retrograde amnesia is the inability to retrieve information that was acquired before a particular date, usually the date of an accident or operation.[3] In some cases the memory loss can extend back decades, while in others the person may lose only a few months of memory. Anterograde amnesia is the inability to transfer new information from the short-term store into the long-term store. People with this type of amnesia cannot remember things for long periods of time. These two types are not mutually exclusive; both can occur simultaneously.

Question: How long can amnesia last?

Spooks (TV series)

Spooks (known as MI-5 in some countries) is a British television drama series that originally aired on BBC One from 13 May 2002 to 23 October 2011, consisting of 10 series. The title is a popular colloquialism for spies, and the series follows the work of a group of MI5 officers based at the service's Thames House headquarters, in a highly secure suite of offices known as The Grid. It is notable for various stylistic touches, and its use of popular guest actors. In the United States, the show is broadcast under the title MI-5. In Canada, the programme originally aired as MI5 but now airs on BBC Canada as Spooks.

Question: How many series of Spooks have been released?

Total War (series)

Total War is a series of strategy games developed by The Creative Assembly for personal computers. They combine turn-based strategy and resource management with real-time tactical control of battles. The first of the series, Shogun: Total War was released in June 2000. The most recent major game released was Total War Saga: Thrones of Britannia on 3 May 2018. The series has sold over 20 million copies.[1]

Question: How many units has Total War sold?
Decemviri

The decemviri took office in 451BC. Both consuls elect, Appius Claudius Crassinus Inregillensis Sabinus and Titus Genucius Augurinus, resigned. So did the other magistrates and the plebeian tribunes. In compensation for their loss of office, Appius Claudius and Titus Genucius were appointed to the decemviri. So was one of the consuls of the previous year (452 BC), Publius Sestius Capitolinus Vaticanus, because he had put the proposal to the senate despite the opposition of his colleague.  The three envoys were also part of the decemviri.[11] The most influential member was Appius Claudius who, according to Livy, "was the guiding hand in the whole magistracy ... thanks to the favour of the plebs."[12] Each day a different decemvir presided over the magistracy and this man had the twelve lictors (the bodyguards of the consuls) with fasces (bound bundles of rods which were the symbol of supreme authority and sometimes had axes). Their rule was fair and their administration of justice was exemplary. Despite not being subject to appeal, they yielded to one another when an appeal was taken. They drafted their laws on ten bronze tables and presented them to the people, asked for feedback and amended them accordingly. They were approved by the higher popular assembly, the Assembly of the Soldiers. There was a general feeling that two more tables were needed to have a corpus of all Roman law. It was decided to elect a new decemvirate.[13]

Question: When were decemvirs first established in the Roman Republic?

Hilbert space

The mathematical concept of a Hilbert space, named after David Hilbert, generalizes the notion of Euclidean space. It extends the methods of vector algebra and calculus from the two-dimensional Euclidean plane and three-dimensional space to spaces with any finite or infinite number of dimensions. It's essentially just an infinitely dimensional vector space. ﻿A Hilbert space is an abstract vector space possessing the structure of an inner product that allows length and angle to be measured. Furthermore, Hilbert spaces are complete: there are enough limits in the space to allow the techniques of calculus to be used.

Question: What is a Hilbert space in algebra?
Go (game)

The playing pieces are called "stones". One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections ("points") of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if "captured". Capture happens when a stone or group of stones is surrounded by opposing stones on all orthogonally-adjacent points.[4] The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second).[5] Games may also be terminated by resignation. A teacher might simplify the explanation by saying to a student "you may place your stone on any point on the board, but if I surround that stone, I will remove it."

Question: What are the pieces in the board game Go?

United States Air Force

The United States Air Force (USAF) is the aerial and space warfare service branch of the United States Armed Forces. It is one of the five branches of the United States Armed Forces, and one of the seven American uniformed services. Initially formed as a part of the United States Army on 1 August 1907, the USAF was established as a separate branch of the U.S. Armed Forces on 18 September 1947 with the passing of the National Security Act of 1947. It is the youngest branch of the U.S. Armed Forces, and the fourth in order of precedence. The USAF is the largest[13] and most technologically advanced[14] air force in the world.  The Air Force articulates its core missions as air and space superiority, global integrated intelligence, surveillance, and reconnaissance, rapid global mobility, global strike, and command and control.

Question: When was the U.S. Air Force established?

Large intestine

In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending the abdomen, across the width of the abdominal cavity as the transverse colon, and then descending to the rectum and its endpoint at the  anal canal.[8] Overall, in humans, the large intestine is about 1.5 metres (5ft) long, which is about one-fifth of the whole length of the gastrointestinal tract.[9]

Question: How long is the large intestine in humans?

Brass instrument

The view of most scholars (see organology) is that the term "brass instrument" should be defined by the way the sound is made, as above, and not by whether the instrument is actually made of brass. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent and the didgeridoo, while some woodwind instruments are made of brass, like the saxophone.

Question: Why are they called brass instruments?
Bonanza

The family lived on a thousand square-mile (2,600 km2) ranch called the Ponderosa on the eastern shore of Lake Tahoe in Nevada opposite California on the edge of the Sierra Nevada range].[10] The vast size of the Cartwrights' land was quietly revised to "half a million acres" (2,000 km2) on Lorne Greene's 1964 song, "Saga of the Ponderosa." The ranch name refers to the Ponderosa Pine, common in the West. The nearest town to the Ponderosa was Virginia City, where the Cartwrights would go to converse with Sheriff Roy Coffee (played by veteran actor Ray Teal), or his deputy Clem Foster (Bing Russell).

Question: Where does the series Bonanza take place?

Forgotten Realms

Forgotten Realms is a campaign setting for the Dungeons & Dragons (D&D) fantasy role-playing game. Commonly referred to by players and game designers alike as "The Realms", it was created by game designer Ed Greenwood around 1967 as a setting for his childhood stories.[1] Several years later, Greenwood brought the setting to the D&D game as a series of magazine articles, and the first Realms game products were released in 1987. Role-playing game products have been produced for the setting ever since, as have various licensed products including novels, role-playing video game adaptations (including the first massively multiplayer online role-playing game to use graphics), and comic books. The Forgotten Realms is one of the most popular D&D settings,[2][3] largely due to the success of novels by authors such as R. A. Salvatore and numerous role-playing video games, including Pool of Radiance (1988), Eye of the Beholder (1991), Baldur's Gate (1998), Icewind Dale (2000) and Neverwinter Nights (2002).

Question: When was the Forgotten Realms campaign of DND first introduced?

Gollum

Gollum is a fictional character from J. R. R. Tolkien's legendarium. He was introduced in the 1937 fantasy novel The Hobbit, and became an important character in its sequel, The Lord of the Rings. Gollum was a Stoor Hobbit[1] of the River-folk, who lived near the Gladden Fields.[2] Originally known as Sméagol, he was corrupted by the One Ring and later named Gollum after his habit of making "a horrible swallowing noise in his throat".[3]

Question: How old is Gollum?

History of the Kansas City metropolitan area

The history of the Kansas City metropolitan area started in the 19th century as Frenchmen from St. Louis, Missouri moved up the Missouri River to trap for furs and trade with the Native Americans. The Kansas City metropolitan area, straddling the border between Missouri and Kansas at the confluence of the Kansas and Missouri Rivers, was a strategic point for commerce and security. Kansas City, Missouri was founded in 1838 and defeated its rival Westport to become the predominant city west of St. Louis. The area played a major role in the westward expansion of the United States. The Santa Fe, and Oregon trails ran through the area. In 1854, when Kansas was opened to Euro-American settlement, the Missouri-Kansas border became the first battlefield in the conflict in the American Civil War.

Question: When was Kansas City founded?
Franz Joseph I of Austria

Franz Joseph I or Francis Joseph I (Franz Joseph Karl; 18 August 1830– 21 November 1916) was Emperor of Austria, King of Hungary, and monarch of many other states of the Austro-Hungarian Empire, from 2 December 1848 to his death.[1] From 1 May 1850 to 24 August 1866 he was also President of the German Confederation. He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third-longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.[2]

Question: Who was the first Austro-Hungarian emperor?

Metro Tunnel

The Metro Tunnel (sometimes also known as the Melbourne Metro Rail Project or the Metro Rail Capacity Project) is a metropolitan rail infrastructure project currently under construction[1] in Melbourne, Australia. It includes the construction of twin 9-kilometre rail tunnels between South Kensington station (north west of the Melbourne City Centre) and South Yarra (in the south east) with five new underground stations. The southern portal for the tunnel is to be located to the south of South Yarra station. As a result, the tunnel will connect the Pakenham and Cranbourne lines with the Sunbury line, and allow these lines to bypass Flinders Street station and the City Loop while still stopping in the Melbourne central business district. 

Question: How long is the Melbourne Metro Tunnel going to be?

History of Tasmania

Tasmania was inhabited by an indigenous population, the Tasmanian Aborigines, and evidence indicates their presence in the territory, later to become an island, at least 35,000 years ago. At the time of the British occupation and colonisation in 1803 the indigenous population was estimated at between 3000 and 10,000. Historian Lyndall Ryan's analysis of population studies led her to conclude that there were about 7000 spread throughout the island's nine nations;[1] Nicholas Clements, citing research by N.J.B. Plomley and Rhys Jones, settled on a figure of 3000 to 4000.[2] The combination of the so-called Black War, internecine conflict and, from the late 1820s, the spread of infectious diseases to which they had no immunity,[3] reduced the population to about 300 by 1833. Almost all of the indigenous population was relocated to Flinders Island by George Augustus Robinson. Until the 1970s, most people thought that the last surviving Tasmanian Aborigine was Trugernanner,[4] who died in 1876. However this "extinction" was a myth, as documented by Lyndall Ryan in 1991.[5]

Question: When was Tasmania first colonized?
Religion in Kosovo

According to the U.S. Department of State's 2007 International Religious Freedom Report, 'the last credible census was taken in the 1980s', and the religious demographics had to be estimated.[5] The Report found that Islam was the predominant faith in Kosovo, 'professed by most of the majority ethnic Albanian population, the Bosniak, Gorani, and Turkish communities, and some of the Roma/Ashkali/Egyptian community'. About 100,000–120,000 people were Serbs, and these were largely Serbian Orthodox. Approximately 3.4% of ethnic Albanians were Catholics, whereas Protestants comprised a minority of less than 1%, there were only two known families of Jewish origin and no reliable data for atheists.[5] It is also likely that there are some Orthodox Albanians in Kosovo. However, with current tension between Kosovars and Serbs, they may feel as if they do not want to identify as Orthodox, as they may be thought of as ‘Serbs’ because of their Orthodox status. Therefore, they are not represented in the census. Furthermore, the Report claimed that religion was 'not a significant factor in public life. Religious rhetoric was largely absent from public discourse in Muslim communities, mosque attendance was low, and public displays of conservative Islamic dress and culture were minimal.'[5]

Question: What is the dominate religion in Pristina?

Pararhabdodon

Pararhabdodon has been classified in a number of different positions within Iguanodontia since its remains were first discovered in the mid-1980s.[1][11] When the first speciemens were originally discovered and described by Casanovas-Cladellas and colleagues, they were not thought to belong a new taxon at all, but merely to belong to the genus Rhabdodon, and of an uncertain species.[3] Not long after, they would be recognized of those of a unique species, and in 1993 they were given their modern name. At this point it was still thought to be a rhabdodontid or some other type of primitive iguanodont closely related to them. This was based on the characteristics of its vertebrae, as the cranial remains had not yet been found.[4] In 1994 these cranial remains would be found - two maxilla - and these would be used by the original authors to establish it as a species of hadrosaur.[6]

Question: When were fossils of the Pararhabdodon first found?
