Neuron
A neuron (American English), neurone (British English), or nerve cell, is an membrane potential#Cell excitability, excitable cell (biology), cell that fires electric signals called action potentials across a neural network (biology), neural network in the nervous system. They are located in the nervous system and help to receive and conduct impulses. Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the synaptic gap. Neurons are the main components of nervous tissue in all Animalia, animals except sponges and placozoans. Plants and fungi do not have nerve cells. Molecular evidence suggests that the ability to generate electric signals first appeared in evolution some 700 to 800 million years ago, during the Tonian period. Predecessors of neurons were the peptidergic secretory cells. They eventually ga ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Baikonur Cosmodrome
The Baikonur Cosmodrome is a spaceport operated by Russia within Kazakhstan. Located in the Kazakh city of Baikonur, it is the largest operational space launch facility in terms of area. All Russian Human spaceflight, crewed spaceflights are launched from Baikonur. Situated in the Kazakh Steppe, some above sea level, it is to the east of the Aral Sea and north of the Syr Darya. It is close to Töretam, a station on the Trans-Aral Railway. Russia, as the official successor state to the Soviet Union, has retained control over the facility since 1991; it originally assumed this role through the post-Soviet Commonwealth of Independent States (CIS), but ratified an agreement with Kazakhstan in 2005 that allowed it to lease the spaceport until 2050. It is jointly managed by Roscosmos and the Russian Aerospace Forces. In 1955, the Ministry of Defense (Soviet Union), Soviet Ministry of Defense issued a decree and founded the Baikonur Cosmodrome. It was originally built as the chief ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Libertad I
Libertad 1 ('Freedom 1') is a single CubeSat built by the Space Program of the Sergio Arboleda University in Colombia. It is the first Colombian satellite sent to orbit. It was launched aboard a Dnepr rocket on April 17, 2007 from the Baikonur Cosmodrome, Kazakhstan and became the first Colombian satellite to orbit the Earth. It used a telemetric payload to keep it in communication with the University. It was expected to have a 50-day lifespan, however news reports two years after it was launched stated the satellite was still working and sending information, passing over Colombia twice a day.

Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Latin American
Latin Americans (; ) are the citizenship, citizens of Latin American countries (or people with cultural, ancestral or national origins in Latin America). Latin American countries and their Latin American diaspora, diasporas are Metroethnicity, multi-ethnic and Multiracial people, multi-racial. Latin Americans are a Panethnicity, pan-ethnicity consisting of people of different ethnic and national backgrounds. As a result, many Latin Americans do not take their nationality as an Ethnic group, ethnicity, but identify themselves with a combination of their nationality, ethnicity and their ancestral origins. In addition to the Indigenous peoples of the Americas, indigenous population, Latin Americans include people with Old World ancestors who arrived since 1492.

Scientist
A scientist is a person who Scientific method, researches to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different er ...

Paracoccidioides Brasiliensis
''Paracoccidioides brasiliensis'' is a dimorphic fungus and one of the two species that cause paracoccidioidomycosis (the other being '' Paracoccidioides lutzii).'' The fungus has been affiliated with the family Ajellomycetaceae (division Ascomycota) although a sexual state or teleomorph has not yet been found. History ''Paracoccidioides brasiliensis'' was first discovered by Adolfo Lutz in 1908 in Brazil. Although Lutz did not suggest a name for the disease caused by this fungus, he made note of structures he called "pseudococcidica" together with mycelium in cultures grown at 25 °C. In 1912, Alfonse Splendore proposed the name ''Zymonema brasiliense'' and described the features of the fungus in culture. Finally in 1930, Floriano de Almeida created the genus ''Paracoccidioides'' to accommodate the species, noting its distinction from ''Coccidioides immitis''. Physiology ''Paracoccidioides brasiliensis'' is a nonphotosynthetic eukaryote with a rigid cell wall and organe ...

Medical Diagnosis
Medical diagnosis (abbreviated Dx, Dx, or Ds) is the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as a diagnosis with the medical context being implicit. The information required for a diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more diagnostic procedures, such as medical tests, are also done during the process. Sometimes the posthumous diagnosis is considered a kind of medical diagnosis. Diagnosis is often challenging because many signs and symptoms are nonspecific. For example, redness of the skin ( erythema), by itself, is a sign of many disorders and thus does not tell the healthcare professional what is wrong. Thus differential diagnosis, in which several possible explanations are compared and contrasted, must be performed. This involves the correlation of various pieces of information followed by the recognition and d ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Virus
A virus is a submicroscopic infectious agent that replicates only inside the living Cell (biology), cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 16,000 of the millions of List of virus species, virus species have been described in detail. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent viral particles, or ''virions'', consisting of (i) genetic material, i.e., long ...

Tuberculosis
Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, is a contagious disease usually caused by ''Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as inactive or latent tuberculosis. A small proportion of latent infections progress to active disease that, if left untreated, can be fatal. Typical symptoms of active TB are chronic cough with hemoptysis, blood-containing sputum, mucus, fever, night sweats, and weight loss. Infection of other organs can cause a wide range of symptoms. Tuberculosis is Human-to-human transmission, spread from one person to the next Airborne disease, through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with latent TB do not spread the disease. A latent infection is more likely to become active in those with weakened I ...
