Causes For Cold Sores Besides Herpes



always humanity, in search of the Divine and the unknown, has gone on fantastic theories about life, as it was, how it will be and how it might be in other worlds.
The taste of the mysterious discovery of new forms of life has always paraded the luminaries in ridiculous and often grotesque processions where surrounded by the traditions of the historical context, browse ancestors of man, and sometimes extinct creatures Hybrids made rule of art, worthy of the best taxidermist's shop.

Earth, a fascinating ball covered with fluid of different density, or "water" or "air". All life forms which inhabit it, or live on the bottom of a fluid, crushed by the pressure, or use the fluid to move or live in symbiosis with other more complex organisms.
Several nights spent searching for the alien came from space, it will have antennae? green skin? may be high or low and bald and with big eyes?

those are alien life forms that undermine the scientific thinking? that disrupt the boundary between animal and plant? Alien the truth is that being alive, whatever form it takes, that uproots a conviction rooted in man of science.
in ocean trenches, where life is unthinkable for a human being, there are alien beings, large enough to be photographed, so you want to see an alien, here it is you, not served from the depths of the universe, but from the depths of our planet ...

More than 2600 m of depth from the bottom of the sea rise, near the oceanic ridges, the "chimneys" from which water flows at very high temperature gas-rich particles and other sulphides.
These areas are characterized by the leakage of warm water from cracks in the basalt along a mid-ocean ridge, may follow at intervals of per km or less. Along the oceanic ridges (but also in the vicinity of subduction zones) the movement of the plates crustali produces, for stretching, cracks in the basalt where water creeps up to several kilometers deep. The high pressure and high temperature, determine the chemical dissolution of minerals in the water, which then resurfaces in submarine hydrothermal vents at temperatures between 5 and 250 ° C. rising to the surface flows resulting in plumes dark (hence the name black smokers) because they are rich in minerals which, in contact with the cold water rushed around giving rise to the "chimneys"

geophysical data suggest that the geochemical and hydrothermal activity does not last more than a few tens of years in one place. In addition to this short life, it is worth mentioning that the temperature fluctuations also shows large and rapid scale daily or hourly, so the organisms that live in these conditions must be adapted to rapid fluctuations in abiotic conditions.
These structures, the "Black smokers" are a very special ecosystem, which does not derive its energy from sunlight, the water temperature here can change from 400 ° C, in the vicinity of the fumaroles, 1-2 ° C a few feet away, but the water, even where it reaches 400 ° C, no bubbles, prevents the enormous pressure from 2500-3000 meters above the sea. Cone near the water is rich in sulfur dioxide, which, in these concentrations, it is a real poison.

The submarine hydrothermal vents are places where there is a strong growth of chemo-autotrophic bacteria, that use as a substrate oxidizing different inorganic compounds containing sulfur.
most abundant and conspicuous animals have evolved symbiotic relationships with these bacteria. And the others with the use as food, beds "bacteria that grow on the substrate of these areas.
Just close jet of hot water geysers, are strange "bushes" of vermiform animals up to one meter long, giant clams, crabs and shrimp that exploit the issue from the bottom of hot water (at temperatures up to 400 ° C) and rich in minerals which comes from underground heated by magma.

These animals (animals because they are) are completely different from any other living on Earth. While every food chain starts, both on land and at sea, with sunlight, water and the plants can perform photosynthesis, near the Black smokers some bacteria use sulfur dioxide instead of sunlight. These bacteria are the first link in a food chain consists of worms, molluscs, crustaceans and fish, all with special features.

Among the molluscs, Bathymodiolus thermophilus and Calyptogena magnificent resort in large numbers (up to 10 kg/m2) in the cracks of the basalt from which the aroma escapes and where insinuate muscular foot. In Calyptogena, which has no digestive tract, it seems that his foot through the highly vascularized be absorbed substances to be oxidized by sulfur bacteria, while the gills to ensure supply of oxygen and inorganic carbon that serve to complete synthesis of chemo- . This is done by a mass of bacterial endosymbionts welcomed into the gill tissue. The foot in these bivalves is also used to navigate on the sea floor in search of cracks "best.

bushes giant worms: "Rift pachyptila" have no mouth or digestive system, live in vertical tubes permanent fixtures in the deep cracks in the basalt.

Their life is based on a chemo-autotrophic symbiosis with the host bacterial flora in a fabric that trofosoma that reaches 50% of their body mass (it would be equivalent to say that half of the body mass of these animals, is composed of bacteria).

The polychaete worms (Annelida) tubicolo Alvinella Pompeians living near the springs and seems to withstand the hottest temperatures up to 350 ° C; receives chemo-autotrophic bacteria on the expansion of parapodi back, but it seems to feed with their mouths.

The shrimp, which are a bit 'far, they have instead of eyes, infrared sensors that allow him to distinguish jets of the fumaroles, thus avoiding burns.

The mid-ocean ridges have been around forever, which is considered Chequesta situations are limited in time, locally, have always existed. Indeed, the organisms that grow near the sulfur springs are considered as examples of the most primitive forms of life that
have developed on Earth when oxygen was still present at the current levels of concentration.

The real aliens are those who are not considered an integral part of the universe and who claim that all life should be compared to man, including man, known to man, while the 'Man is just a ring, a dimension of sight, the harmony of others.
The man thinks and believes he is the only one to do that, maybe so, but maybe not this should not put the man above the material, because it is matter, bacteria, cells, life on life, amassed, accumulated and kneaded by invisible hands.
