Foxfire (Ultraverse)
Foxfire, also called fairy fire and chimpanzee fire, is the bioluminescence created by some species of fungi present in decaying wood. The bluish-green glow is attributed to a luciferase, an oxidative enzyme, which emits light as it reacts with a luciferin. The phenomenon has been known since ancient times, with its source determined in 1823. Description Foxfire is the bioluminescence created by some species of fungi present in decaying wood. It occurs in a number of species, including ''Panellus stipticus'', '' Omphalotus olearius'' and '' Omphalotus nidiformis''. The bluish-green glow is attributed to luciferin, which emits light after oxidation catalyzed by the enzyme luciferase. Some believe that the light attracts insects to spread spores, or acts as a warning to hungry animals, like the bright colors exhibited by some poisonous or unpalatable animal species. Although generally very dim, in some cases foxfire is bright enough to read by. History The oldest recorded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aposematism
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioluminescence
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and somet ...

Will-o'-the-wisp
In folklore, a will-o'-the-wisp, will-o'-wisp or ''ignis fatuus'' (, plural ''ignes fatui''), is an atmospheric ghost light seen by travellers at night, especially over bogs, swamps or marshes. The phenomenon is known in English folk belief, English folklore and much of European folklore by a variety of names, including jack-o'-lantern, friar's lantern, hinkypunk and is said to mislead travellers by resembling a flickering lamp or lantern. In literature, will-o'-the-wisp metaphorically refers to a hope or goal that leads one on, but is impossible to reach, or something one finds strange or sinister. Wills-o'-the-wisp appear in folk tales and traditional legends of numerous countries and cultures; notable wills-o'-the-wisp include St. Louis Light in Saskatchewan, the Spooklight in Southwestern Missouri and Northeastern Oklahoma, the Marfa lights of Texas, the Naga fireballs on the Mekong in Thailand, the Paulding Light in Upper Peninsula of Michigan and the Hessdalen light i ...

List Of Bioluminescent Fungi
] Found largely in temperate and tropical climates, currently there are more than 112 known species of bioluminescent fungi, all of which are members of the order Agaricales (Basidiomycota) with one exceptional ascomycete belonging to the order Xylariales. All known bioluminescent Agaricales are mushroom-forming, white-spored agarics that belong to four distinct evolutionary lineages. The Omphalotus lineage (comprising the genera ''Omphalotus'' and '' Neonothopanus'') contains 12 species, the ''Armillaria'' lineage has 10 known species, while the Mycenoid lineage ('' Favolachia, Mycena'', '' Panellus'', '' Prunulus'', '' Roridomyces'') has more than 50 species. The recently discovered Lucentipes lineage contains two species, ''Mycena lucentipes'' and '' Gerronema viridilucens'', which belong to a family that has not yet been formally named. ''Armillaria mellea'' is the most widely distributed of the luminescent fungi, found across Asia, Europe, North America, and South Africa. Bi ...

Finnish Language
Finnish ( endonym: or ) is a Uralic language of the Finnic branch, spoken by the majority of the population in Finland and by ethnic Finns outside of Finland. Finnish is one of the two official languages of Finland (the other being Swedish). In Sweden, both Finnish and Meänkieli (which has significant mutual intelligibility with Finnish) are official minority languages. The Kven language, which like Meänkieli is mutually intelligible with Finnish, is spoken in the Norwegian county Troms og Finnmark by a minority group of Finnish descent. Finnish is typologically agglutinative and uses almost exclusively suffixal affixation. Nouns, adjectives, pronouns, numerals and verbs are inflected depending on their role in the sentence. Sentences are normally formed with subject–verb–object word order, although the extensive use of inflection allows them to be ordered differently. Word order variations are often reserved for differences in information structure. Finnish orth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aurora Borealis
An aurora (plural: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky. Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/ exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of accelerati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Folklore
Japanese folklore encompasses the informally learned folk traditions of Japan and the Japanese people as expressed in its oral traditions, customs, and material culture. In Japanese, the term is used to describe folklore. The academic study of folklore is known as . Folklorists also employ the term or to refer to the objects and arts they study. Folk religion Men dressed as namahage, wearing ogre-like masks and traditional straw capes (''mino'') make rounds of homes, in an annual ritual of the Oga Peninsula area of the Northeast region. These ogre-men masquerade as kami looking to instill fear in the children who are lazily idling around the fire. This is a particularly colorful example of folk practice still kept alive. A parallel custom is the secretive ritual of the Yaeyama Islands, Okinawa which does not allow itself to be photographed. Many, though increasingly fewer households maintain a kamidana or a small Shinto altar shelf. The Shinto version of the kitchen go ...

Benjamin Gale
Benjamin Gale (December 14, 1715May 6, 1790) was an American physician, scientist, agriculturist, inventor and political polemicist who was known for his political protests against the New Lights, which resulted in a fifteen year pamphlet war against leader Thomas Clap, and was himself considered a leader of Old Light politics in Connecticut. Gale was born in Jamaica, Queens. After graduating from Yale University, he moved to Killingworth, Connecticut where he further studied medicine and surgery. Throughout the next decade he would indulge in several business ventures and investments, which led to his invention of the drill plough. He was elected as justice of the peace and state representative in 1747, and would serve in those capacities until 1773 and 1770 respectively. In 1755, Gale would publish his first pamphlet against Thomas Clap, which he wrote as a response against an earlier pamphlet written by Clap. This pamphlet ended up being successful, prompting a pamphle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Turtle
''Turtle'' (also called ''American Turtle'') was the world's first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against Royal Navy vessels occupying American harbors during the American Revolutionary War. Connecticut Governor Jonathan Trumbull recommended the invention to George Washington, who provided funds and support for the development and testing of the machine. Several attempts were made using ''Turtle'' to affix explosives to the undersides of British warships in New York Harbor in 1776. All failed, and her transport ship was sunk later that year by the British with the submarine aboard. Bushnell claimed eventually to have recovered the machine, but its final fate is unknown. Modern replicas of ''Turtle'' have been constructed and are on display in the Connecticut River Museum, the U.S. Navy's Submarine Force Library and Museum, ...

Pliny The Elder
Gaius Plinius Secundus (AD 23/2479), called Pliny the Elder (), was a Roman author, naturalist and natural philosopher, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclopedic ''Naturalis Historia'' (''Natural History''), which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. His nephew, Pliny the Younger, wrote of him in a letter to the historian Tacitus: Among Pliny's greatest works was the twenty-volume work ''Bella Germaniae'' ("The History of the German Wars"), which is no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus and Suetonius. Tacitus—who many scholars agree had never travelled in Germania—used ''Bella Germani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
