Biological classification

Biological classification
The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown. Modern biological classification has its root in the work of Carolus Linnaeus, who grouped species according to shared physical characteristics. Definition[edit] Biological types[edit] The scientific names of taxa are formally attached to a type, which is one particular specimen (or in some cases a group of specimens, or in some cases an illustration) of the organism, preserved in a museum. Taxonomic ranks[edit] A classification as defined above is hierarchical. The level, for nomenclatural purposes, of a taxon in a taxonomic hierarchy (e.g., all families are for nomenclatural purposes at the same rank, which lies between superfamily and subfamily).[5] Ranks are somewhat arbitrary, but hope to encapsulate the diversity contained within a group—a rough measure of the number of diversifications that the group has been through.[6] Early systems[edit] Early methodists[edit] Related:  Sciencemental disorders in the 16th-18th centuriesBiology: terms

Stanford Scientists Observe Man Travel Out of His Body and Into Space – What He Saw Was Remarkable NASA’s Pioneer 10 spacecraft was launched into space in 1972. It was the the very first spacecraft to fly directly through the asteroid belt and make observations of the biggest planet in our solar system, Jupiter. It was also able to obtain closeup images of the planet, something that scientists had never had access to before. (1) Prior to the flyby of Jupiter by Pioneer 10, the CIA and NSA, in conjunction with Stanford University, were involved in what was called “Remote Viewing.” Remote viewing can be defined in multiple ways. A gentlemen by the name of Ingo Swann was able to successfully describe and view a ring around Jupiter, a ring that scientists had no idea existed. The successful viewing of the ring by Ingo came after scientists observed him identify physical objects in hidden envelopes that were placed a few hundred kilometers away. It’s remarkable to think about these extended human capacities, and what we are capable of. The Above Information Was Documented. Sources:

Nosology Nosology (from Ancient Greek νόσος (nosos), meaning "disease", and -λογία (-logia), meaning "study of-") is a branch of medicine that deals with classification of diseases. Types of classification[edit] A chief difficulty in nosology is that diseases often cannot be defined and classified clearly, especially when etiology or pathogenesis are unknown. History[edit] In the 18th century, the taxonomist Carolus Linnaeus, Francois Boissier de Sauvages, and psychiatrist Philippe Pinel developed an early classification of physical illnesses. The early nosological efforts grouped diseases by their symptoms, whereas modern systems (e.g. Applications[edit] Nosology is used extensively in public health, to allow epidemiological studies of public health issues.

Groundbreaking Idea Of Life's Origin Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.” From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity.

Watercolor Reflections Seed saving Partial shelled popcorn seed saved for planting Open Pollination[edit] Open pollination is an important aspect of seed saving. Plants that reproduce through natural means tend to adapt to local conditions over time, and evolve as reliable performers, particularly in their localities, known as landraces or "folk varieties." Method[edit] Care must be taken, as training materials regarding seed production, cleaning, storage, and maintenance often focus on making landraces more uniform, distinct and stable (usually for commercial application) which can result in the loss of valuable adaptive traits unique to local varieties (Jarvis et al., 2000). Additionally, there is a matter of localized nature to be considered. Legality[edit] Significantly, farmers in developing countries are particularly affected by prohibitions on seed saving. In the United States, by contrast, the farmer's privilege is considered protected by the Plant Variety Protection Act and by case law stemming from Asgrow Seed v.

Scientist In Russia Photographs The Soul Leaving The Body At Death [VIDEO] | THEFRT.COM The timing of astral disembodiment in which the spirit leaves the body has been captured by Russian scientist Konstantin Korotkov, who photographed a person at the moment of his death with a bioelectrographic camera. The image taken using the gas discharge visualization method, an advanced technique of Kirlian photography shows in blue the life force of the person leaving the body gradually. According to Korotkov, navel and head are the parties who first lose their life force (which would be the soul) and the groin and the heart are the last areas where the spirit before surfing the phantasmagoria of the infinite. In other cases according to Korotkov has noted that “the soul” of people who suffer a violent and unexpected death usually manifests a state of confusion in your power settings and return to the body in the days following death. The technique developed by Korotkov, who is director of the Research Institute of Physical Culture, St.

Classification of mental disorders The classification of mental disorders, also known as psychiatric nosology or taxonomy, is a key aspect of psychiatry and other mental health professions and an important issue for people who may be diagnosed. There are currently two widely established systems for classifying mental disorders—Chapter V of the International Classification of Diseases (ICD-10) produced by the World Health Organization (WHO) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) produced by the American Psychiatric Association (APA). Both list categories of disorders thought to be distinct types, and have deliberately converged their codes in recent revisions so that the manuals are often broadly comparable, although significant differences remain. Definitions[edit] Mental disorders are generally classified separately to neurological disorders, learning disabilities or mental retardation. ICD-10[edit] Within each group there are more specific subcategories. DSM-IV[edit] Other schemes[edit]

Here's the tiny human twig in the Tree of Life Each Christmas, the BMJ (formerly the British Medical Journal) gets a little bit festive, releasing a special edition filled with goofy research papers. The science is real, but the topics are ridiculous. Last year, papers covered topics such as the origins of magic, how much James Bond really drank, and the physical responses to a public unicycler. This year, the highlight comes in the form of a paper led by a 15-year-old student Ben Alexander Daniel Lendrem, from the King Edward VI School in the UK, and his dad Dennis Lendrem, a statistician from the UK's Institute of Cellular Medicine, who studies the behaviour of human decision-making. The premise of their paper is their ‘Male Idiot Theory’ (MIT), and with this in mind, they examined all past winners of the infamous Darwin Awards. Interestingly, the Lendrems found that of the 318 cases reported to the Darwin Awards, 282 of them - so 88.7 percent - were performed by men. The team reports in the BMJ:

Arches Watercolor Paper Arches papers aren’t just for watercolors. Use them also for drawing, calligraphy, gouache, printmaking, acrylics, and even digital printing. Manufactured from pure cotton fiber, they are so durable that they will remain beautiful and vibrant for centuries without conservation, if stored and handled properly. Many artists say they choose Arches because working on an inferior surface just isn’t worth the effort. This paper is the original Arches, sometimes known as Natural White. Arches watercolor papers are mouldmade in France, with 100% cotton fiber content. Article The new law in question [2] heralds the entry into Iraqi law of patents on life forms - this first one affecting plants and seeds. This law fits in neatly into the US vision of Iraqi agriculture in the future - that of an industrial agricultural system dependent on large corporations providing inputs and seeds. In 2002, FAO estimated that 97 percent of Iraqi farmers used saved seed from their own stocks from last year's harvest or purchased from local markets. "If the FAO is celebrating 'Biodiversity for Food Security' this year, it needs to demonstrate some real commitment", says Henk Hobbelink of GRAIN, pointing out that the FAO has recently been cosying up with industry and offering support for genetic engineering [3].

Did the Big Bang create a parallel universe where time goes backwards? But in a quirk of science it is thought that if a parallel universe did exist where time moved backward, any sentient beings there would consider that time in our universe in fact moved backward. The arrow of time is also known as the 'one-way' direction of time and was devised by a British scientist, Dr Arthur Eddington, in the twenties. VIDEO: Proof of the Big Bang Dr Barbour told the MailOnline that the mirror universe was a possibility because all of the laws of physics apply no matter which way time is moving and therefore there is no scientific impediment to such a parallel universe. He said: "Time is a mystery. "If you look at a simple model with a swarm of bees in the middle of the Big Bang but breaking up in either direction, then you would say there are two arrows of time, pointing in opposite direction from the swarm. However Dr Barbour acknowledges that locating the 'other' universe in practical terms is an altogether different question.

Outline of physical science Physical science is the study of physics and chemistry of nature.[citation needed] From the materialist and functionalist viewpoints it overlaps the life sciences where ecology studies the evidences of historical facts or evolution. Natural sciences bridge the phenomena in the physical sciences to the noumenon in the life sciences. General principles of the physical sciences[edit] The foundations of the physical sciences rest upon key concepts and theories, each of which explains and/or models a particular aspect of the behavior of nature. Basic principles of physics[edit] Physics, along with mathematics and chemistry,[citation needed] classes as one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. Basic principles of astronomy[edit] Astronomy is the science of celestial bodies and their interactions in space. The life and characteristics of stars and galaxiesOrigins of the universe.
