Metahuman (other)
In the DC Universe, a metahuman is a character with superpowers. The term is roughly synonymous with the terms ''mutant'', ''inhuman'' and ''mutate'' in the Marvel Universe and ''posthuman'' in the Wildstorm and Ultimate Marvel Universes. In DC Comics, the term is used loosely in most instances to refer to any human or human-like being with extraordinary powers, abilities or other attributes, either cosmic, mutant, scientific, mystical, skill or technological in nature. A significant portion of these are normal human beings born with a genetic variant called the "metagene", which causes them to gain powers and abilities during freak accidents or times of intense psychological distress. The term was first used as a reference to superheroes in 1986 by author George R. R. Martin, first in the ''Superworld'' role playing system, and then later in his ''Wild Cards'' series of novels.

Dominators (DC Comics)
The Dominators, collectively known as the Dominion, are a fictional character alien race appearing in comics and other media by DC Comics. Coming from the outer cosmos of the DC Universe, they are highly technologically advanced, and live in a rigid hierarchical society, in which one's caste is determined by the size of a red circle on one's forehead. They are master geneticists who can manipulate the metagene to enhance members of their own caste. Publication history Their first appearance was in 1967, in '' Adventure Comics'' #361, a story written by Jim Shooter with art by Curt Swan and Jim Mooney, in which they are presented as possibly dangerous to the Legion of Super-Heroes, but do not pose an actual threat. They appeared again in ''Legion of Super-Heroes'' #241–245 in the late 1970s, as an adversarial race in an interstellar conflict with Earth in the 30th century. In 1988 and 1989, they were revived as the villains of the " Invasion!" crossover event involving man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloodstream
The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek ''kardia'' meaning ''heart'', and from Latin ''vascula'' meaning ''vessels''). The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with the ''circulatory system''. The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Some invertebrates such as arthro ...

Magic (paranormal)
Magic, sometimes spelled magick, is an ancient praxis rooted in sacred rituals, spiritual divinations, and/or cultural lineage—with an intention to invoke, manipulate, or otherwise manifest supernatural forces, beings, or entities in the natural, incarnate world. It is a categorical yet often ambiguous term which has been used to refer to a wide variety of beliefs and practices, frequently considered separate from both religion and science. Although connotations have varied from positive to negative at times throughout history, magic continues to have an important religious and medicinal role in many cultures today. Within Western culture, magic has been linked to ideas of the Other, foreignness, and primitivism; indicating that it is "a powerful marker of cultural difference" and likewise, a non-modern phenomenon. During the late nineteenth and early twentieth century, Western intellectuals perceived the practice of magic to be a sign of a primitive mentality and also commo ...

Technology
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Metamorphosis (biology)
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation an ...

Metastable
In chemistry and physics, metastability denotes an intermediate Energy level, energetic state within a dynamical system other than the system's ground state, state of least energy. A ball resting in a hollow on a slope is a simple example of metastability. If the ball is only slightly pushed, it will settle back into its hollow, but a stronger push may start the ball rolling down the slope. Bowling pins show similar metastability by either merely wobbling for a moment or tipping over completely. A common example of metastability in science is isomerisation. Higher energy isomers are long lived because they are prevented from rearranging to their preferred ground state by (possibly large) barriers in the potential energy. During a metastable state of finite lifetime, all state-describing parameters reach and hold stationary values. In isolation: *the state of least energy is the only one the system will inhabit for an indefinite length of time, until more external energy is added ...

Meta (prefix)
Meta (from the Greek , ''meta'', meaning "after" or "beyond") is an adjective meaning "more comprehensive" or "transcending". In modern nomenclature, the prefix meta- can also serve as a prefix meaning self-referential, as a field of study or endeavor (metatheory: theory about a theory; metamathematics: mathematical theories about mathematics; meta-axiomatics or meta-axiomaticity: axioms about axiomatic systems; metahumor: joking about the ways humor is expressed; etc.). Original Greek meaning In Greek, the prefix ''meta-'' is generally less esoteric than in English; Greek ''meta-'' is equivalent to the Latin words ''post-'' or ''ad-''. The use of the prefix in this sense occurs occasionally in scientific English terms derived from Greek. For example, the term ''Metatheria'' (the name for the clade of marsupial mammals) uses the prefix ''meta-'' in the sense that the ''Metatheria'' occur on the tree of life adjacent to the ''Theria'' (the placental mammals).

Black Canary
The Black Canary is the name of two superheroines appearing in American comic books published by DC Comics: Dinah Drake and her daughter Dinah Laurel Lance. The original version was created by the writer-artist team of Robert Kanigher and Carmine Infantino, the character debuted in ''Flash Comics'' #86 (August 1947). One of DC's earliest superheroines, the title Black Canary has appeared in many of the company's flagship team-up titles, including ''Justice Society of America'' and ''Justice League of America''. Since the late 1960s, the character has been paired with archer superhero the Green Arrow, both professionally and romantically. As well as featuring in many Green Arrow stories, she is closely associated with the Batman family of characters, and specifically Barbara Gordon, her best friend, with whom she leads the superhero team Birds of Prey. The Black Canary has been adapted into various media. In ''Birds of Prey'' television series she was played by Rachel S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Erectus
''Homo erectus'' (; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Several human species, such as '' H. heidelbergensis'' and '' H. antecessor'' — with the former generally considered to have been the ancestor to Neanderthals, Denisovans, and modern humans — appear to have evolved from ''H. erectus''. Its specimens are among the first recognizable members of the genus ''Homo''. ''H. erectus'' was the first human ancestor to spread throughout Eurasia, with a continental range extending from the Iberian Peninsula to Java. Asian populations of ''H. erectus'' may be ancestral to '' H. floresiensis'' and possibly to '' H. luzonensis''. The last known population of ''H. erectus'' is '' H. e. soloensis'' from Java, around 117,000–108,000 years ago. ''H. erectus'' had a more modern gait and body proportions, and was the first human species to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australopithecus Afarensis
''Australopithecus afarensis'' is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. From 1972 to 1977, the International Afar Research Expedition—led by anthropologists Maurice Taieb, Donald Johanson and Yves Coppens—unearthed several hundreds of hominin specimens in Hadar, Ethiopia, the most significant being the exceedingly well-preserved skeleton AL 288-1 ("Lucy") and the site AL 333 ("the First Family"). Beginning in 1974, Mary Leakey led an expedition into Laetoli, Tanzania, and notably recovered fossil trackways. In 1978, the species was first described, but this was followed by arguments for splitting the wealth of specimens into different species given the wide range of variation which had been attributed to sexual dimorphism (normal differences between males and females).
