Scientific knowledge is very advanced and depends on the teamwork of many anonymous people. In addition, new things are investigated and found to be a boring and complex process (those who do not get the most out of it for so long), and it is difficult to understand from outside. With regard to these reasons, the media speaks only of major advances and strangest or most intelligible discoveries.
Although they are not the most important investigations, this year they have left strange and truly impressive progress. Some people are not considered an anecdote, but others hope to extend their scientific journey.
A new body organ
Finding a new body occurs in the human body. In May 2018, scientists at the University of New York School of Medicine (USA) discovered "interstitium", which covered the fluid-filled tissue network and other organs under the skin. Until now, he has gone unnoticed, because anatomical observation techniques have not been observed by focusing on the tissue samples of chemicals. In general, there was a word of interstitial space, placed between cells, but not the same organ.

"This finding has the potential to bring about tremendous progress in medicine, the ability to take samples of interstitial fluid is a powerful tool for diagnostic tools," said researcher Neil Theise and the School of School of Medicine. New York and co-author of the research.
New geometric shape
In 2018, scientists also found a new geometric shape while embryonic animal development research was underway. In a study published in Nature Communications, they say that embryo cells are multiplied and truncated in three-dimensional forms, they are configured in the form of "escutoides" and provide a great deal of stability.

This new shape has curved surfaces and at least one plane at two feet. "We achieved great results in our modeling work," said Javier Buceta Lehigh University (USA) research and scientist, in a statement. "Our model is foreseen because the curvature of the canvas increases, so that more forms appear in simple columns or bottles." In our surprise, we do not even have a mathematician name. This is not a chance to name a new form. "
Bacteria that live in the brain?
This year, researchers from the University of Alabama at the University of Birmingham (USA) analyzed brain samples when they found long-term forms. The following observations have shown that the locations are three bacteria of the microbial groups found in the intestine. For the time being, research does not exclude bacteria that are involved in brain cells due to contamination, but suggests that bacterial bacteria in healthy people may be.

This finding has sparked the interest of the researchers because they suggest that these microorganisms are harmful or beneficial. If confirmed, "there is a paradigm shift when we think of the brain," said leading researcher Rosalinda Roberts.
"Selfies" deceives you
Rutgers University Medical School A group of New Jersey researchers reaffirmed what the intuition is already: it has the potential to self-distort the size of its nose.
"Young people – Boris Paskhover affirms that the Department of Earol-Anesthesiology of the aforementioned organizations – are continuously being held in their social networks and believe that they actually see their images, how they affect their emotional state."
Paskhover, in fact, said that many of his patients showed that they had to undergo surgery because they reduced the size of the nose. In fact, a report from the American Academy of Plastic and Constructive Facial Surgery said 55% of surgeons have said that people are focusing on their services to achieve more precise procedures and "self-esteem". .
A new kind of neuron
This year, a group of nanosciences discovered a type of brain cell, the neuron was raised and found only in humans.
It is a type of neuron that is around 10% of brain brain regions that develop around 10% of the neurons neurons, because it forms a bush, which is very important in the brain region in evolutionary evolution and hearing and hearing.
Researchers are still unaware of the function of the neuron, but usually associated with pyramidal cells, which are the type of excitatory neuron acting as a brake.
Electricity in the intestine
A published study Nature Research by scientists from California, California, Berkeley (USA) demonstrated that hundreds of bacteria are capable of producing intestinal microbial electricity. So far, this ability has allowed microorganisms to be found in anoxic environments (without oxygen), such as sediment pains and lakes, but never in the intestine.
Specifically, scientists have discovered a new mechanism that uses microbes, such as microbes, such as lactobacilli, streptococci and pathogens that cause diarrhea.Listeria monocytogenes), gangrene (Clostridium perfringens) or hospital infections (Enterococcus faecalis).

"In fact, humans, such as mutagenic, pathogens, probiotics or part of the microbial, or those involved in fermenting certain products, are electro-genetic," said Dan Portnoy, researcher at Berkeley. responsible for research. "We have not forgotten until now, it's an interesting thing to know how to infect these bacteria or have a healthy intestine."
The space approached the Earth
A research published by Acta Astronautic certifies that the boundary between the Earth and the external space, Karman line, is 20% higher than previously thought, that is to say, at an altitude of 80 kilometers and not 100.
Until then, the scientists were 100 kilometers tall. Thereafter, according to the aerodynamic expert Theodore von Kármán, it is the same velocity that it is necessary to keep an airplane in the atmosphere at the same time as in the plane.
Astrophysicist Jonathan McDowell, Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. The researcher completed a wide-ranging record that started the rocket. Thus, the outer space is 85 kilometers high, called mesopause (the coldest part of the atmosphere).
Thousands of satellites and an orbital data of a model concluded that the atmosphere and space boundaries are between 66 and 88 kilometers in height. Although there are no changes to the launch of ships and rockets, it will be important to implement spatial policies and laws.
Gate door to death
The Romans believed that the world was covered in doors to hell. The priests led by complex rituals, where they placed live animals at the gates of hell, they could see how the helpers killed them without human intervention.
In the ancient city of Hierapolis, in Turkey, there is a plutonium called Plutonius, in honor of Pluto, the god of the underworld. This doorway, to access a small stone, is in the middle of a field with thermal activity. Additionally, it is built above a volcanic base that emits carbon dioxide. This gas, which is harmful to low concentrations, is to kill it. In fact, in 2011, the birds that fly close to the door were found to die.

This year, Hardy Pfanz's pen, the Duisburg-Essen (Germany) University wants to explore the deadly force of the door for more details. That's why, as the day goes by, CO2 plays a different role. One day he disappears and forms a small "lakes" that accumulate on the ground at night. At dawn, the door becomes deadly when the gas is lifted and has a height of 40 centimeters, just after killing animals or people.
Pfanz concluded that the priests had made sacrifice at dawn or afternoon and knowing that the deadly force of the door was only a certain height. That is why humans were able to enter, but animals were killed, as they show historical records.
