Transplant rejection

Transplant rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue.  Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of immunosuppressant drugs after transplant.[1]

Question: What does transplant rejection mean?

William O'Brien

William O'Brien (2 October 1852 – 25 February 1928) was an Irish nationalist, journalist, agrarian agitator, social revolutionary, politician, party leader, newspaper publisher, author and Member of Parliament (MP) in the House of Commons of the United Kingdom of Great Britain and Ireland. He was particularly associated with the campaigns for land reform in Ireland during the late 19th and early 20th centuries as well as his conciliatory approach to attaining Irish Home Rule.

Cretaceous

The Cretaceous (/krɪˈteɪʃəs/, kri-TAY-shəs) is a geologic period and system that spans 79 million years from the end of the Jurassic Period 145 million years ago (mya) to the beginning of the Paleogene Period 66 mya.  It is the last period of the Mesozoic Era, and the longest period of the Phanerozoic Eon.  The Cretaceous Period is usually abbreviated K, for its German translation Kreide (chalk, creta in Latin).

Question: When did the Cretaceous period begin?

Halley's Comet

Halley's returns to the inner Solar System have been observed and recorded by astronomers since at least 240 BC. Clear records of the comet's appearances were made by Chinese, Babylonian, and medieval European chroniclers, but were not recognized as reappearances of the same object at the time. The comet's periodicity was first determined in 1705 by English astronomer Edmond Halley, after whom it is now named.

Question: Who discovered Halley's Comet?

Tristan und Isolde

Tristan und Isolde (Tristan and Isolde, or Tristan and Isolda, or Tristran and Ysolt) is an opera, or music drama, in three acts by Richard Wagner to a German libretto by the composer, based largely on the 12th-century romance Tristan by Gottfried von Strassburg. It was composed between 1857 and 1859 and premiered at the Königliches Hof- und Nationaltheater in Munich on 10June 1865 with Hans von Bülow conducting. Wagner referred to the work not as an opera, but called it "eine Handlung" (literally a drama, a plot or an action), which was the equivalent of the term used by the Spanish playwright Calderón for his dramas.

Question: When did Wagner compose Tristan und Isolde?
St. Audoen's Church, Dublin (Church of Ireland)

St Audoen's Church (/ˈɔːdən/) is the church of the parish of Saint Audoen in the Church of Ireland, located south of the River Liffey at Cornmarket in Dublin, Ireland. This was close to the centre of the medieval city. The parish is in the Diocese of Dublin and Glendalough. St Audoen's is the oldest parish church in Dublin and still used as such. There is a Roman Catholic  church of the same name adjacent to it.

Penicillin

Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming.[3] People began using it to treat infections in 1942.[4] There are several enhanced penicillin families  which are effective against additional bacteria; these include the antistaphylococcal penicillins, aminopenicillins and the antipseudomonal penicillins. They are derived from Penicillium fungi.[5]

Question: When was penicillin discovered?

Trade unions in Germany

The most important labor organization is the German Confederation of Trade Unions (Deutscher Gewerkschaftsbund, or DGB), which is the umbrella association of eight single trade unions for individual economic sectors, representing more than 6 million people as of 2014. The largest single trade union is the IG Metall, which as of 2014 organizes about 2.3 million members in metal (including automobile and machine building), electronics, steel, textile, wood and synthetics industries.

Question: What's the biggest union in Germany?

Cogito, ergo sum

Descartes first wrote the phrase in French in his 1637 Discourse on the Method. He referred to it in Latin without explicitly stating the familiar form of the phrase in his 1641 Meditations on First Philosophy. The earliest written record of the phrase in Latin is in his 1644 Principles of Philosophy, where, in a margin note (see below), he provides a clear explanation of his intent: "[W]e cannot doubt of our existence while we doubt". Fuller forms of the phrase are attributable to other authors.

Question: When did Descartes write "I think, therefore I am"?

Pinball

In 1869, British inventor Montague Redgrave settled in the United States and manufactured bagatelle tables in Cincinnati, Ohio. In 1871 Redgrave was granted U.S. Patent #115,357 for his "Improvements in Bagatelle",[1] another name for the spring launcher that was first introduced in Billard japonais. The game also shrank in size to fit atop a bar or counter. The balls became marbles and the wickets became small metal pins. Redgrave's popularization of the spring launcher and innovations in game design are acknowledged as the birth of pinball in its modern form.

Question: Who invented pinball?
Survivor Series (1993)

The event consisted of four tag-team elimination matches and a bout for the Smoky Mountain Wrestling Tag Team Championship. The main event match saw the All-Americans, a team of face wrestlers from the United States, competing against the Foreign Fanatics, a team of heels that represented other countries. The All-Americans won the match when Lex Luger was the last man remaining. In an undercard match, four members of the Hart family competed against Shawn Michaels and a group of masked men. The original plan was for the Harts to face Jerry Lawler, with whom they were feuding, but Lawler was not able to appear at the event having been fired after being indicted for raping a 13 year old girl[1][2]. The Harts won the match, but a confrontation between Bret Hart and Owen Hart after the match led to Owen turning against the family the following year.

Question: Who won the Survivor Series in 1993?

History of nuclear weapons

In January 1933, Adolf Hitler was appointed Chancellor of Germany and it quickly became unsafe for Jewish scientists to remain in the country. Leó Szilárd fled to London where he proposed, and in 1934 patented, the idea of a nuclear chain reaction via neutrons. The patent also introduced the term critical mass to describe the minimum amount of material required to sustain the chain reaction and its potential to cause an explosion. (British patent 630,726.) He subsequently assigned the patent to the British Admiralty so that it could be covered by the Official Secrets Act.[2] In a very real sense, Szilárd was the father of the atomic bomb academically.
Also in 1934, Irène and Frédéric Joliot-Curie discovered that artificial radioactivity could be induced in stable elements by bombarding them with alpha particles; Enrico Fermi reported similar results when bombarding uranium with neutrons.

Question: When was the first nuclear weapon created?

Liberia

Liberia (/laɪˈbɪəriə/(listen)), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south-southwest. It covers an area of 111,369 square kilometers (43,000sqmi) and has a population of around 4,700,000 people.[7] English is the official language and over 20 indigenous languages are spoken, representing the numerous ethnic groups who make up more than 95% of the population. The country's capital and largest city is Monrovia.

Fullmetal Alchemist

The manga has sold over 70 million volumes worldwide, making it one of the best-selling manga series. The English release of the manga's first volume was the top-selling graphic novel during 2005. In two TV Asahi web polls, the anime was voted the most popular anime of all time in Japan. At the American Anime Awards in February 2007, it was eligible for eight awards, nominated for six, and won five. Reviewers from several media conglomerations had positive comments on the series, particularly for its character development, action scenes, symbolism and philosophical references.

Question: How many awards has Fullmetal Alchemist won?
Battle of Kham Duc

The Battle of Kham Duc was a major battle of the Vietnam War (in Vietnam the "American War"). The event occurred in Khâm Đức, now district capital of Phước Sơn District, then in Quảng Tín Province (now part of Quảng Nam Province, South Vietnam), from 10–12 May 1968. During the Tet Offensive of 1968, the People's Army of Vietnam (PAVN) 2nd Division tried to capture Đà Nẵng, but they were defeated in the Battle of Lo Giang by elements of the U.S. 1st Marine Division, the 23rd Infantry Division (Americal). PAVN General Chu Huy Mân decided to disengage from the fight in the outskirts of the city, and pull the 2nd Division into the mountains where they could rest, rebuild, and prepare for the next major operation. Khâm Đức, a small district in the north of Quảng Tín, was chosen as the next target for the 2nd Division. Following their defeat at Đà Nẵng, U.S. military intelligence agencies in I Corps Tactical Zone were confused by the movements of the 2nd Division, because they could not track down the unit.

Question: When was the Battle of Kham Duc?

Endocrinology

The earliest study of endocrinology began in China.[14] The Chinese were isolating sex and pituitary hormones from human urine and using them for medicinal purposes by 200 BCE.[14] They used many complex methods, such as sublimation of steroid hormones.[14] Another method specified by Chinese texts—the earliest dating to 1110—specified the use of saponin (from the beans of Gleditsia sinensis) to extract hormones, but gypsum (containing calcium sulfate) was also known to have been used.[14]

Question: Who first identified the endocrine system?

William Perry

William James Perry (born October 11, 1927) is an American mathematician, engineer, and businessman who was the United States Secretary of Defense from February 3, 1994, to January 23, 1997, under President Bill Clinton.[1] He also served as Deputy Secretary of Defense (1993–1994)[2] and Under Secretary of Defense for Research and Engineering (1977–1981).

Question: What was William James Perry's job before he was name Secretary of Defense?

Screw

A screw is a type of fastener, in some ways similar to a bolt (see Differentiation between bolt and screw below), typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and  prevent pull-out. There are many screws for a variety of materials; those commonly fastened by screws include wood, sheet metal, and plastic.

Question: What are screws most commonly made of?
Transcription (biology)

RNA polymerase, together with one or more general transcription factors, binds to promoter DNA.
RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. This is done by breaking the hydrogen bonds between complementary DNA nucleotides.
RNA polymerase adds RNA nucleotides (which are complementary to the nucleotides of one DNA strand).
RNA sugar-phosphate backbone forms with assistance from RNA polymerase to form an RNA strand.
Hydrogen bonds of the RNA–DNA helix break, freeing the newly synthesized RNA strand.
If the cell has a nucleus, the RNA may be further processed. This may include polyadenylation, capping, and splicing.
The RNA may remain in the nucleus or exit to the cytoplasm through the nuclear pore complex.

Question: What triggers transcription in DNA?

Panzer VIII Maus

Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.

Question: What was the largest tank in history?

Intel 4004

The chip design started in April 1970, when Federico Faggin joined Intel, and was completed under his leadership in January 1971.  The first commercial sale of the fully operational 4004 occurred in March 1971 to Busicom Corp. of Japan for which it was originally designed and built as a custom chip.[3] In mid-November of the same year, with the prophetic ad "Announcing a new era in integrated electronics", the 4004 was made commercially available to the general market. The 4004 was the first commercially available monolithic processor, fully integrated in one small chip. Such a feat of integration was made possible by the use of the then-new silicon gate technology for integrated circuits, originally developed by Faggin (with Tom Klein) at Fairchild Semiconductor in 1968, which allowed twice the number of random-logic transistors and an increase in speed by a factor of five compared to the incumbent MOS aluminum gate technology.[4] Faggin also invented the bootstrap load with silicon gate and the “buried contact”, improving speed and circuit density compared with aluminum gate.[5][6][7][8][9]

Question: Who developed the first CPU?

History of Warsaw

The first historical document attesting to the existence of a Warsaw castellan dates to 1313.[2] Fuller information about the age of the city is contained in the court case against the Teutonic Knights, which took place in Warsaw cathedral in 1339.[2] In the beginning of the 14th century it became one of the seats of the Dukes of Masovia, becoming the capital of Masovia in 1413 (Prince Janusz II).[1] Warsaw's economy of the 14th century rested on crafts and trade. The townsmen, of uniform nationality at the time, were marked by a great disparity in their financial status.[2] At the top were the rich patricians while the plebeians formed the lower strata.[2]

Question: When was Warsaw founded?
Siamese fireback

The Siamese fireback is distributed to the lowland and evergreen forests of Cambodia, Laos, Thailand and Vietnam in Southeast Asia. This species is also designated as the national bird of Thailand. The female usually lays between four and eight rosy eggs.

Question: What's the national bird of Thailand?

Pack (canine)

Animals which typically predominate over others are associated with the term alpha. Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition. 

Question: What is the leader of a wolf pack called?

List of the largest libraries in the United States

The largest public library in the United States—and the largest library in the world—is the Library of Congress in Washington, D.C., which is the de facto national library of the United States.[2] It holds more than 167 million items, including "more than 39 million books and other printed materials, 3.6 million recordings, 14.8 million photographs, 5.5 million maps, 8.1 million pieces of sheet music and 72 million manuscripts."[3] Other than the Library of Congress, the largest public library in the United States is the New York Public Library, while the largest research library in the United States is the Harvard Library.

Question: What is the biggest library in US?

South African Army

The role of the Army was fundamentally changed by the upheavals of the early 1990s and after 1994 the Army became part of the new South African National Defence Force. It is now becoming increasingly involved in peacekeeping efforts in southern Africa, often as part of wider African Union operations. The Army is composed of roughly 40,100 regular uniformed personnel, augmented by 12,300 reserve force personnel. The rank/age structure of the army, which deteriorated desperately during the 1990s, is greatly improving through the Military Skills Development (MSDS) voluntary national service system. Through this system, young healthy members are being inducted into the regular and reserve forces every year.

Question: How big is the South African army?

Judo

Judo(wikt:柔道,jūdō, meaning "gentle way") was originally created in 1882 by Jigoro Kano (嘉納治五郎) as a physical, mental and moral pedagogy in Japan. It is generally categorized as a modern martial art, which later evolved into a combat and Olympic sport. Its most prominent feature is its competitive element, where the objective is to either throw or takedown an opponent to the ground, immobilize or otherwise subdue an opponent with a pin, or force an opponent to submit with a joint lock or a choke. Strikes and thrusts by hands and feet as well as weapons defenses are a part of judo, but only in pre-arranged forms (kata, 形) and are not allowed in judo competition or free practice (randori, 乱取り). A judo practitioner is called a judoka.

Question: What is the name for someone who practices judo?
Horse

Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30years.[7] Uncommonly, a few animals live into their 40s and, occasionally, beyond.[8] The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62.[7] In modern times, Sugar Puff, who had been listed in Guinness World Records as the world's oldest living pony, died in 2007 at age 56.[9]

Question: What is the life expectancy of horses?

Elizabeth of Russia

In the late 1750s Elizabeth's health started to decline. She began to suffer a series of dizzy spells and refused to take the prescribed medicines. She forbade the word "death" in her presence.[34] Elizabeth suffered a stroke on Christmas Eve 1761. Knowing that she was dying, Elizabeth used her last remaining strength to make her confession, to recite with her confessor the prayer for the dying and to say farewell to those few people who wished to be with her, including Peter and Catherine and Counts Alexei and Kirill Razumovsky. The Empress died the next day, 25 December 1761.[35] For her lying in state she was dressed in a shimmering silver dress; she was beautiful in death as she had been in life. She was buried in the Peter and Paul Cathedral in Saint Petersburg on 3 February 1762 after six weeks lying in state.[34]

Question: How did Elisabeth Petrovna die?

Hollywood Sign

"HOLLYWOOD" is spelled out in 45-foot (13.7m)-tall[1] white capital letters and is 352 feet (107.3 m) long. The sign was originally created in 1923 as an advertisement for a local real estate development, but due to increasing recognition, the sign was left up.[2] The sign has been a frequent target of pranks and vandalism across the decades, but it has since undergone restoration, including the installation of a security system to deter vandalism. The sign is protected and promoted by The Hollywood Sign Trust,[3] a nonprofit organization, while its site and the surrounding land are part of Griffith Park.

Question: How long was Holy Wood?

RNA

Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the nitrogenous bases of guanine, uracil, adenine, and cytosine, denoted by the letters G, U, A, and C) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.

Question: What's RNA?
History of photography

In the mid-1820s, Nicéphore Niépce first managed to fix an image that was captured with a camera, but at least eight hours or even several days of exposure in the camera were required and the earliest results were very crude. Niépce's associate Louis Daguerre went on to develop the daguerreotype process, the first publicly announced  and commercially viable photographic process. The daguerreotype required only minutes of exposure in the camera, and produced clear, finely detailed results. The details were introduced as a gift to the world in 1839, a date generally accepted as the birth year of practical photography.[1][2]
The metal-based daguerreotype process soon had some competition from the paper-based calotype negative and salt print processes invented by William Henry Fox Talbot. Subsequent innovations made photography easier and more versatile. New materials reduced the required camera exposure time from minutes to seconds, and eventually to a small fraction of a second; new photographic media were more economical, sensitive or convenient, including roll films for casual use by amateurs. In the mid-20th century, developments made it possible for amateurs to take pictures in natural color as well as in black-and-white.

Question: Who invented photography?

History of rail transport

The first full-scale working railway steam locomotive was built in the United Kingdom in 1804 by Richard Trevithick, a British engineer born in Cornwall. This used high-pressure steam to drive the engine by one power stroke. The transmission system employed a large flywheel to even out the action of the piston rod. On 21 February 1804, the world's first steam-powered railway journey took place when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in South Wales.[28][29] Trevithick later demonstrated a locomotive operating upon a piece of circular rail track in Bloomsbury, London, the Catch Me Who Can, but never got beyond the experimental stage with railway locomotives, not least because his engines were too heavy for the cast-iron plateway track then in use.[30]

Question: When was the first train invented?
