Controversial Science
Fringe science refers to ideas whose attributes include being highly speculative or relying on premises already refuted. Fringe science theories are often advanced by persons who have no traditional academic science background, or by researchers outside the mainstream discipline. The general public has difficulty distinguishing between science and its imitators, and in some cases a "yearning to believe or a generalized suspicion of experts is a very potent incentive to accepting pseudoscientific claims". The term "fringe science" covers everything from novel hypotheses which can be tested by means of the scientific method to wild ad hoc hypotheses and mumbo jumbo. This has resulted in a tendency to dismiss all fringe science as the domain of pseudoscientists, hobbyists, and quacks. A concept that was once accepted by the mainstream scientific community may become fringe science because of a later evaluation of previous research. For example, focal infection theory, which hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Objection (argument)
In argumentation, an objection is a reason arguing against a premise, argument, or conclusion. Definitions of objection vary in whether an objection is always an argument (or counterargument) or may include other moves such as questioning. An objection to an objection is sometimes known as a rebuttal. An objection can be issued against an argument retroactively from the point of reference of that argument. This form of objection – invented by the presocratic philosopher Parmenides – is commonly referred to as a retroactive refutation. Inference objection An inference objection is an objection to an argument based not on any of its stated premises, but rather on the relationship between a premise and main contention. For a given simple argument, if the assumption is made that its premises are correct, fault may be found in the progression from these to the conclusion of the argument. This can often take the form of an unstated co-premise, as in begging the question. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mad Scientist
The mad scientist (also mad doctor or mad professor) is a stock character of a scientist who is perceived as " mad, bad and dangerous to know" or " insane" owing to a combination of unusual or unsettling personality traits and the unabashedly ambitious, taboo or hubristic nature of their experiments. As a motif in fiction, the mad scientist may be villainous (evil genius) or antagonistic, benign, or neutral; may be insane, eccentric, or clumsy; and often works with fictional technology or fails to recognise or value common human objections to attempting to play God. Some may have benevolent intentions, even if their actions are dangerous or questionable, which can make them accidental antagonists. History Prototypes The prototypical fictional mad scientist was Victor Frankenstein, creator of his eponymous monster, who made his first appearance in 1818, in the novel '' Frankenstein, or the Modern Prometheus'' by Mary Shelley. Though the novel's title character, Victor Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epigenetics
In biology, epigenetics is the study of stable phenotypic changes (known as ''marks'') that do not involve alterations in the DNA sequence. The Greek prefix '' epi-'' ( "over, outside of, around") in ''epigenetics'' implies features that are "on top of" or "in addition to" the traditional genetic basis for inheritance. Epigenetics most often involves changes that affect the regulation of gene expression, but the term can also be used to describe any heritable phenotypic change. Such effects on cellular and physiological phenotypic traits may result from external or environmental factors, or be part of normal development. The term also refers to the mechanism of changes: functionally relevant alterations to the genome that do not involve mutation of the nucleotide sequence. Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. Gene express ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategies For Engineered Negligible Senescence
Strategies for engineered negligible senescence (SENS) is a range of proposed regenerative medical therapies, either planned or currently in development, for the periodic repair of all age-related damage to human tissue. These therapies have the ultimate aim of maintaining a state of negligible senescence in patients and postponing age-associated disease.de Grey, Aubrey; Rae, Michael (September 2007). ''Ending Aging: The Rejuvenation Breakthroughs that Could Reverse Human Aging in Our Lifetime''. New York, NY: St. Martin's Press, 416 pp. . SENS was first defined by British biogerontologist Aubrey de Grey. While some biogerontologists support the SENS program, others contend that the ultimate goals of de Grey's programme are too speculative given the current state of technology. The 31-member Research Advisory Board of de Grey's SENS Research Foundation have signed an endorsement of the plausibility of the SENS approach. Framework The term "negligible senescence" was first used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longevity
The word " longevity" is sometimes used as a synonym for " life expectancy" in demography. However, the term ''longevity'' is sometimes meant to refer only to especially long-lived members of a population, whereas ''life expectancy'' is always defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of cohorts). Longevity is best thought of as a term for general audiences meaning 'typical length of life' and specific statistical definitions should be clarified when necessary. Reflections on longevity have usually gone beyond acknowledging the brevity of human life and have included thinking about methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction, and utopian novels. In fact the legendary fountain of youth appeared in the work of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
60 Minutes
''60 Minutes'' is an American television news magazine broadcast on the CBS television network. Debuting in 1968, the program was created by Don Hewitt and Bill Leonard, who chose to set it apart from other news programs by using a unique style of reporter-centered investigation. In 2002, ''60 Minutes'' was ranked number six on ''TV Guide''s list of the " 50 Greatest TV Shows of All Time", and in 2013, it was ranked number 24 on the magazine's list of the "60 Best Series of All Time". ''The New York Times'' has called it "one of the most esteemed news magazines on American television". Originally airing in 1968, the program began as a bi-weekly television show hosted on CBS hosted by Mike Wallace and Harry Reasoner. The two sat on opposite sides of the cream-colored set, though the set's color was later changed to black, the color still used today. The show used a large stopwatch during transition periods and highlighted its topics through chroma key—both techniques are s ...

Clovis Culture
The Clovis culture is a prehistoric Paleoamerican culture, named for distinct stone and bone tools found in close association with Pleistocene fauna, particularly two mammoths, at Blackwater Locality No. 1 near Clovis, New Mexico, in 1936 and 1937 (though Paleoindian artifacts had been found at the site since the 1920s). It appears around 11,500–11,000 uncalibrated years before present (YBP)"Clovis Culture" entry in the ''Concise Oxford Dictionary of Archaeology'': "9,500–9,000 BC". at the end of the last glacial period and is characterized by the manufacture of " Clovis points" and distinctive bone and ivory tools. Archaeologists' most precise determinations at present suggest this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago. The only human burial that has been directly associated with tools from the Clovis culture included the remains of an infant boy researchers named Anzick-1.

Fringe Theory
A fringe theory is an idea or a viewpoint which differs from the accepted scholarship of the time within its field. Fringe theories include the models and proposals of fringe science, as well as similar ideas in other areas of scholarship, such as the humanities. In a narrower sense, the term ''fringe theory'' is commonly used as a pejorative; it is roughly synonymous with the term pseudo-scholarship. Precise definitions that make distinctions between widely held viewpoints, fringe theories, and pseudo-scholarship are difficult to construct because of the demarcation problem. Issues of false balance or false equivalence can occur when fringe theories are presented as being equal to widely accepted theories. Definitions Fringe theories are ideas which depart significantly from a prevailing or mainstream theory. A fringe theory is neither a majority opinion nor that of a respected minority. In general, the term ''fringe theory'' is closer to the popular understanding of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Extraction
A dental extraction (also referred to as tooth extraction, exodontia, exodontics, or informally, tooth pulling) is the removal of teeth from the dental alveolus (socket) in the alveolar bone. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which have become unrestorable through tooth decay, periodontal disease, or dental trauma, especially when they are associated with toothache. Sometimes impacted wisdom teeth (wisdom teeth that are stuck and unable to grow normally into the mouth) cause recurrent infections of the gum ( pericoronitis), and may be removed when other conservative treatments have failed (cleaning, antibiotics and operculectomy). In orthodontics, if the teeth are crowded, healthy teeth may be extracted (often bicuspids) to create space so the rest of the teeth can be straightened. Procedure Extractions could be categorized into non-surgical (simple) and surgical, depending on the type of tooth to be removed and othe ...

Focal Infection Theory
Focal infection theory is the historical concept that many chronic diseases, including systemic and common ones, are caused by focal infections. In present medical consensus, a focal infection is a localized infection, often asymptomatic, that causes disease elsewhere in the host, but focal infections are fairly infrequent and limited to fairly uncommon diseases. (Distant injury is focal infection's key principle, whereas in ordinary infectious disease, the infection itself is systemic, as in measles, or the initially infected site is readily identifiable and invasion progresses contiguously, as in gangrene.)J Craig Baumgartner, José F Siqueira Jr, Christine M Sedgley & Anil Kishen, ch 7 "Microbiology of endodontic disease", in John I Ingle, Leif K Bakland & J Craig Baumgartner, eds, ''Ingle's Endodontics'', 6th edn (Hamilton Ontario: BC Decker, 2008)p 221–24 Focal infection theory, rather, so explained virtually all diseases, including arthritis, atherosclerosis, cancer, an ...

Orgone
Orgone () is a pseudoscientific concept variously described as an esoteric energy or hypothetical universal life force. Originally proposed in the 1930s by Wilhelm Reich, and developed by Reich's student Charles Kelley after Reich's death in 1957, orgone was conceived as the anti-entropic principle of the universe, a creative substratum in all of nature comparable to Mesmer's animal magnetism (1779), to the Odic force (1845) of Carl Reichenbach and to Henri Bergson's ''élan vital'' (1907).Charles R. Kelley Ph.D., "What is Orgone Energy?" 1962 Orgone was seen as a massless, omnipresent substance, similar to luminiferous aether, but more closely associated with living energy than with inert matter. It could allegedly coalesce to create organization on all scales, from the smallest microscopic units—called "bions" in orgone theory—to macroscopic structures like organisms, clouds, or even galaxies. Reich argued that deficits or constrictions in bodily orgone were at the roo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
