Feeds on bacteria and arsenic, as well as DNA phosphorus was used as a building block instead of the toxic substance. This discovery, the rule of life on earth to be destroyed due to 6 elements, arsenic has also been added to it. Strengthened the possibility of life on other planets. Mars exploration plan will be reviewed again even.
LAST week all internet sites, the U.S. Space and Aviation Agency NASA's extraterrestrial life or a creature shaken rumors hint that it finds. To learn that we are not alone in the universe is finally preparation of the evening before NASA did not provide answer to this description has been a revolution in the biological sciences.
Mono Lake in California, a bacterium called GFAJ-1, in which all the other creatures that we, unlike the first time arsenic instead of phosphorus available to the molecular structure emerged. This discovery is important because for the first time in the world of life 'of carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur' in the form of element 6 is connected to the general rule that was destroyed.
6 elements wanted
Discovery of this fascinating life and the world to rethink, to reassess the findings obtained from the force as well as other planets. For example, Moon or another planet in the light of this information is obtained from the material or images will be discussed now. For example, arsenic in the presence of intense symptoms that may be evidence that there might be life on the planet. Scientists are always searching for other planets biological traces 'of carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur' looking for materials. Earth and the discovery of extraterrestrial life that may upset their research uncovered the bacteria to live and beslenmekle not only arsenic, arsenic also adds its own DNA and cells.
There are unwritten laws
In fact, all studies on this subject, a few years ago, the unwritten laws of biology and the world may be on the possibility of different forms of life appeared in the three debates between scientists. American Geophysical Institute (USGS) Astrobiology, Professor Felisa Wolfe-Simon, and Paul Davies at the University of Arizona researchers, Ariel Anbar, a joint study in 2009, some life forms in the world, arsenic in the periodic table of elements close to each other as indicated phosphorus take place.
DNA changed
Then Felisa Wolfe-Simon, a high level of arsenic in the salt and the Mono Lake, California began work to put forward this theory in experiments. Bacteria grows all how much better the large amount of phosphorus, arsenic and a bottle containing a small amount of phosphorus in the continued life. Wolfe-Simon surprised him in the bacterium's DNA, but also of phosphorus instead of arsenic koyabilmesiydi beslenmekle.
In fact, not new
GFAJ-1 'Halomonadaceae gamma probakteri' family, it emphasizes that a bacterium known to scientists, this is actually not a new situation, but so far no one "enemy of arsenic in an environment such as the development of life" might be thought, the difference is not recorded. Professor Anbar, "Here is a new element, the use of arsenic as a building block for the organism," he said. Foundation for Applied Molecular Evolution arsenic researcher Steven Benner of DNA and proteins take part in the opinion proved.
Arsenic 'phosphorus poisonous cousin'
ARSENIC table of the elements phosphorus and it just under the common feature of many chemicals. Therefore, "phosphorus poisonous cousin," he is known. The difference between the two substances of biological cells to detect the full effect of arsenic is poison. Cells use of phosphorus instead of arsenic. Because the arsenic-based compounds, less water remains constant. This is not to the normal function of cells and leads to die.
Mono Lake, work in progress
California's Mono Lake, a 16-kilometer-long coast, frantic work in progress. Echoing around the world in the field of Biology and the major breakthrough discovery, scientists in all excited. American Geophysical Institute (USGS) Astrobiology, Professor Felisa Wolfe-Simon, released Mono Lake continues to investigate the sediment core samples. Professor, is helping his team.
Change agenda against WikiLeaks'e
NASA's description of the "life found in space" waiting for announcement of creating web sites disappointment "that the agenda to reduce leaks WikiLeaks" comments that roamed the purpose. These comments by American writer Dan Brown's 'Deception Point' reminded me of the book. This book is a meteorite from outer space on the alleged fossils, was thinking may be life in space. But the book reveals that this was not the original heroes and the United States presidential election, he was changing dramatically.
A falling meteorite from Mars in 1995 NASA had lived in great excitement the discovery of the Antarctic. In fact, this incident led to kurumlaşmasına astrobiyolojinin. However meteorda found traces of life so far.
Science 's Sacred Kâse'si
The new space will open
University of Arizona professor Paul Davies: This organism has the capacity to double. Both phosphorus, arsenic and grow. This is her 'thing' not do a separate origin of the tree of life makes a different. However GFAJ-1 ", even more strange," organisms that may be associated with. This may be the Holy Grail of a substance does not contain any phosphorus. Certainly the tip of the iceberg GFAJ-1 and will open a new area of microbiology.
Arsenic in the space we call
University of London Imperial astrobiyoloğu Zita Martins: The discovery showed that the width of life on earth. Life just is not life as we know it. Very low-high temperatures and even other organisms can live in acidic environments can be. Now, the arsenic will seek a space journey. However, only certain elements, particularly trace of life on planets such as Mars, but more complex molecules such as amino acids and nucleic acid sought.
Android as we
Astrobiyoloğu Caleb Scharf of Columbia University: This is nothing without our food is thrown into a room full of electronic scraps after the android (android) dönüşmemiz something like.
