21:00 GMT at NASA headquarters in Washington, at the press conference, conducts research at Arizona State University team name at the beginning of Dr. Simon Wolfe spoke of Felis. Simon, which until now have all the life forms decompose into bio-molecular structure of about germs GFAJ-1 presented the results of their research.
Dr. Simon Wolfe, at the beginning of the press conference made the following statement:
"Today we'll talk thing, a very long time since the results of an investigation will be made. Arsenic discovered a microbe containing the basic molecules. So far we know nothing, for the life of six elements, namely carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur was that necessary. These elements are DNA, proteins, fats and cells, has the structure of information. microbe has discovered the molecular structure of arsenic takes place in the elements. "
Simon, "GFAJ-1", so called since the microbe can do something unprecedented and "the necessary elements for the life of one of the most accepted and will arsenic instead of phosphorus," he said. Simon, germs, and a unique ecosystem in the state of California have discovered the Mono Lake said.
Mono Lake, denizlerdekinin have three times the rate of salt. In addition, because of too much concentration of arsenic contains an ecosystem that makes life impossible.
CHANGED ALL THE THEORIES
Simon and his team, however, does not allow the formation of life GFAJ-1 so far unprecedented in the lake survives by creating a bio-molecular structure was revealed.
Simon, "Arsenic, phosphorus in the periodic table is just below. These two elements is similar to the physical size of the atom. In addition, there are similarities in chemical structures. Laboratory tests done on the environment, germs, phosphorus-free environment, we investigated how to remain alive. All the other elements necessary the environment, too much phosphorus is completely freed and added amount of arsenic. After all, germs have grown and evolved we have seen, "he said.
Simon, shown in animation made the following comments: "In order to understand how it is received after the outcome examined the DNA of germs. Here, we found arsenic. Just like the phosphorus, arsenic was in the cell and had established links with DNA. In short, phosphorous, arsenic where it should be there. "
The obtained findings indicating that Simon has written over everything known so far, "All the theories have changed. A completely different molecular structure in the world as we know there is an organism can live. Basic molecules are in the arsenic," he said.
PEOPLE OF SCIENCE its views
NASA's own television and internet site published in the conference live, study, conveyed the views of scientists. University of Arizona, James Elser, used the following phrases:
"The discovery is of great importance in the name of a very large and humanity. All research in the field of ecology, phosphorus moss and countless species of animals live up to holding a very important place for the show. Cereal production, plant life, many elements such as high quality fertilizer containing phosphorus for the ecological revolution required. In addition, the phosphorus in different types of ecosystems for a variety of life is also very important. In short, life sustaining, be habitable ecosystems and an essential element in the name of the organism's life. "
"We're getting a phosphorus minerals formed billions of years. However, these minerals are very different and particular geological spread rapidly depleted by their locations are coming to Morocco. The green revolution that something needed to be a threat to the future of humanity to live. However, the molecular structure of phosphorus instead of using his elements instead of using an intelligent being to another, make it easier to everything. "
Elser, a method of bio-energy production can be achieved to ensure the presence of phosphorus is very important, in this context, the presence of DNA of an organism that uses arsenic instead of phosphorus in a shocking development, he said.
Organic chemist Steve Banner made the following statement:
"As chemists say it is an exceptional discovery. Very little phosphorus, arsenic, the more a content, a feature seen so far. Arsenic, a weak link in the DNA structure is the microbe can say. Ties of different elements correspond to each other, break the DNA chain. Study of the organism's DNA spiral of arsenic with, what looked like extraterrestrial beings will have about a much broader perspective. "
Banner, "the weak link in the DNA can measure the temperature. Saturn's moon Titan, the atmosphere is colder than Earth. Under these conditions, arsenic can be much more useful. In short, a cold environment, for arsenic will be more stable ecosystem. "
"THE DOOR ARALADIK"
Power Lab, NASA's Jet thrust officer Pamela Conrad, "the environment can create many different matrices. How this occurs, the chemical environment, the layout has a investigating how the molecular structure of the elements that can change an ecosystem with fewer organisms and understand how life has occurred. The basic elements of life among a beginning, a bacteria that use arsenic to explore, "he said.
Simon made the discovery not only about the arsenic, the organism has been discovered so far outside the accepted rules, he said. Simon, "a large door araladık. So far we are in a lot of questions about the universe cevaplamıyordu glimpses. We found a part of the tree of life thing. What else can find the tree of life and think about what sorabileceğimizi. Sorgulamalıyız can find forms of life in different corners of the universe to another," he said.
Simon, GFAJ-1 germ, with a molecular feature that is able to achieve at the end of a transformation never know how he said. Simon, phosphorous, a substance found in the rocks because of how very little evidence of life is the life of the different elements coming together in a more rapid evolution of phosphorus provides the opportunity, he said. Simon, 30 years to replace the different elements, different elements that will explore the function metabolizmalarda said.
Simon, GFAJ-1 from the germ to their data, how exactly that survives koyamadığını said. The molecular structure of the germ contains very little phosphorus arsenikten oluşmadığının completely underlined.
James the moss to obtain energy, to produce high quality fertilizer, alternative methods of bio-energy development as well as to ensure sustainability issues, said that arsenic can be achieved by ensuring the transformation of waste.
"Disappointment" REACTION
Among the questions that came after the first comments stated that there was disappointment. Ames Research Center is attached to a listener, Simon "Why did you believe that the research is really a remarkable thing," he asked.
Simon, "the basic elements to survive outside the presence of arsenic using the organism is very great and very thorough study was carried out a reconnaissance, he said. Simon, in response to another question, Mono Lake, there are other elements other than phosphorus, which in turn GFAJ-1 of DNA transformation undergone defended psychologists, arsenic, he said.
A journalist from the newspaper USA Today, the disclosure of the existence of aliens has created expectations for those who expressed disappointment. Simon, understand it, but said the discovery will provide important new research areas.
Chemist Banners, GFAJ-1 on the isotope and radioactive imaging tests continue doing experiments and exploring the evolution of germs, he said.
Banners, different backgrounds in the world of science, culture, society and science come together in many of the individual human being, but stressed that the joint work product.
