Escherichia coli (), also known as E. coli (), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. Most E. coli strains are harmless, but some serotypes (EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. Most strains do not cause disease in humans and are part of the normal microbiota of the gut; such strains are harmless or even beneficial to humans (although these strains tend to be less studied than the pathogenic ones). For example, some strains of E. coli benefit their hosts by producing vitamin K2 or by preventing the colonization of the intestine by pathogenic bacteria. These mutually beneficial relationships between E. coli and humans are a type of mutualistic biological relationship — where both the humans and the E. coli are benefitting...

The Great Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The Library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts. The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the Library, but the Library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The Library quickly acquired many papyrus scrolls, owing largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many such scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height. Alexandria came to be regarded as the capital of knowledge and learning, in part because of the Great Library. Many important and influential scholars worked at the Library during the third and second centuries...

A kimchi refrigerator is a refrigerator designed specifically to meet the storage requirements of kimchi and facilitate different fermentation processes. The kimchi refrigerator aims to be colder, with more consistent temperature, more humidity, and less moving air than a conventional refrigerator, providing the ideal environment for fermentation of kimchi. Some models may include features such as a UV Sterilizer.In a consumer survey aimed at Korean homemakers conducted by a top-ranking Korean media agency in 2004, the kimchi refrigerator was ranked first for most wanted household appliance. History and design The start of the Kimchi refrigerator dates back to 1984. At that time, LG predecessor, GoldStar (Hangul: 금성사), first used the word 'Kimchi refrigerator' (Hangul: 김치 냉장고). The model name of the first kimchi refrigerator was 'GR-063', and according to the advertisement (video), the inside was made of stainless steel and the internal temperature could be set, but it is assumed that the direct cooling method was adopted. The volume of this product was 45 liters. After many years of comprehensive work on...

The Illustrated London News appeared first on Saturday 14 May 1842, as the world's first illustrated weekly news magazine. Founded by Herbert Ingram, it appeared weekly until 1971, then less frequently thereafter, and ceased publication in 2003. The company continues today as Illustrated London News Ltd, a publishing, content, and digital agency in London, which holds the publication and business archives of the magazine. History 1842–1860: Herbert Ingram The Illustrated London News founder Herbert Ingram was born in Boston, Lincolnshire, in 1811, and opened a printing, newsagent, and bookselling business in Nottingham around 1834 in partnership with his brother-in-law, Nathaniel Cooke. As a newsagent, Ingram was struck by the reliable increase in newspaper sales when they featured pictures and shocking stories. Ingram began to plan a weekly newspaper that would contain pictures in every edition.Ingram rented an office, recruited artists and reporters, and employed as his editor...

A hagiography (; from Ancient Greek ἅγιος, hagios 'holy', and -γραφία, -graphia 'writing') is a biography of a saint or an ecclesiastical leader, as well as, by extension, an adulatory and idealized biography of a preacher, priest, founder, saint, monk, nun or icon in any of the world's religions. Early Christian hagiographies might consist of a biography or vita, a description of the saint's deeds or miracles (from Latin vita, life, which begins the title of most medieval biographies), an account of the saint's martyrdom (called a passio), or be a combination of these. Christian hagiographies focus on the lives, and notably the miracles, ascribed to men and women canonized by the Roman Catholic church, the Eastern Orthodox Church, the Oriental Orthodox churches, and the Church of the East. Other religious traditions such as Buddhism, Hinduism, Taoism, Islam, Sikhism and Jainism also create and maintain hagiographical texts (such as the Sikh Janamsakhis...

Emotion classification, the means by which one may distinguish or contrast one emotion from another, is a contested issue in emotion research and in affective science. Researchers have approached the classification of emotions from one of two fundamental viewpoints: that emotions are discrete and fundamentally different constructs that emotions can be characterized on a dimensional basis in groupings Emotions as discrete categories In discrete emotion theory, all humans are thought to have an innate set of basic emotions that are cross-culturally recognizable. These basic emotions are described as "discrete" because they are believed to be distinguishable by an individual's facial expression and biological processes. Theorists have conducted studies to determine which emotions are basic. A popular example is Paul Ekman and his colleagues...

A medicine man or medicine woman is a traditional healer and spiritual leader who serves a community of Indigenous people of the Americas. Individual cultures have their own names, in their respective languages, for spiritual healers and ceremonial leaders in their particular cultures. Cultural context In the ceremonial context of Indigenous North American communities, "medicine" usually refers to spiritual healing. Medicine men/women should not be confused with those who employ Native American ethnobotany, a practice that is very common in a large number of Native American and First Nations households.The terms medicine people or ceremonial people are sometimes used in Native American and First Nations communities, for example, when Arwen Nuttall (Cherokee) of the National Museum of the American Indian writes, "The knowledge possessed by medicine people is privileged, and it often remains in particular families."Native Americans tend to be quite reluctant to discuss issues about medicine or medicine people with non-Indians. In some cultures, the...

A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator).While primarily used to detect the development and movement of storm systems and other cloud patterns, meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, and energy flows. Other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El Niño and its effects on weather are monitored daily from satellite images. The Antarctic ozone hole is mapped from weather satellite data. Collectively, weather satellites flown by the U.S., Europe...

Jewel Changi Airport (also known as Jewel or Jewel Changi) is a nature-themed entertainment and retail complex surrounded by and linked to Changi Airport, Singapore, linked to one of its passenger terminals. Its centrepiece is the world's tallest indoor waterfall, the Rain Vortex, that is surrounded by a terraced forest setting.Jewel includes gardens, attractions, a hotel, about 300 retail and dining outlets, as well as early baggage check-in aviation facilities.
