The scientist claims the bacterium is here Grow under the gravity of 40 ten thousand times of earth
Organize the network according to the American physicist 27 days of April (Beijing time) The report, the Japanese scientist is here>On if you can't publish by thesis, claim is it different types of many kinds of whether can in surviving, breeding than the earth gravity a large environments overweight of more than 40 times in bacterium, perhaps for think life on earth might come from to suffused with one kind of theories, produce evidence other celestial body this.
In the experiment, Japanese ocean and the intersection of the earth and science and technology study the intersection of biologist and the intersection of export and luxuriant the intersection of scientific research and group of leader of society, use one overspeed centrifuge let 4 different bacterium rotate, in order to duplicate the overweight strength environment, and tested the survival ability of bacteria under the environment of overweight strength.
They find in surprise, though is increasing with the gravity constantly, these bacteria will cluster round together and form the tiny particle, but its growth speed is not influenced. Two kinds of bacteria among them - -Vice coccus of denitrification and Escherichia coli still can continue growing, breeding in 40 ten thousand times under overweight strength environment of gravity of the earth, the gravity of 40 ten thousand times of earth is the greatest gravity that the scientist can be produced through experimental facilities too. In addition it proves, some microorganisms could survive under the environment of more than 1.5 ten thousand times of gravity of the earth gravity to once study before this, all these show, many kinds of microorganisms all have ability able to bear overweight strength in fact.
The scientists think, breed the reason free of overweight strength and lie in its size and structure in growth of the microorganism. The smaller the microorganism is, the lower its sensitivity to the gravity is. The bacterium is a kind of original nuclear living beings, it has no cell device. The cells device such as nucleus etc. make the compactness easily and close because the effect of subsiding, the bacterium will not meet this question.
However, researchers are still unable to explain why ability that some bacteria are able to bear overweight strength is stronger than other bacteria, they hope to explain this problem by further research.
Support the scientist suffused with one kind of theories to think, when the comet or asteroid and the earth which carries the microorganism collides, the life on the earth begins to be born. However, evidence does not indicate so far the microorganism on the earth is the offspring of the extraterrestrial life, so, the scientist is unable to verify falsfication to this theory, it is only a kind of possibility that the reason of life on earth arises.
The scientist says, the latest research indicates, perhaps the extraterrestrial environment which the life may exist is more numerous extremely than the ones that imagined; This result of study has even improved the possibility with the life in environment beyond the planet greatly. In the past, the scientist thought, the gravity on the brown dwarf lay between 10 time to 100 time of gravity of the earth, the life is unable to store under this kind of gravity environment alive, but the latest research indicates the situation is not like this. In addition, the meteorite may produce 30 ten thousand times of gravity of the earth to strike, the latest research shows too, perhaps the microorganism can survive in this kind of environment too and normal reproduction.
Punctuate :
Want to peep the miracle of the life, how can only see the higher living beings. F1 racing-cycle side direction have 4 nearly year, astronaut training require Damien 8, but small bacterium face 40 ten thousand pieces of dementia of g toss about calmly, wait until water bear's worm that can be put up in the vacuum with grace kicks the hall, then let no one dare to call " L Strong " R (used after a verb to indicate the completion of an action). Can seem to support the environment that the life entity survives " L Non- reasonable " R One o'clock. But some scientists are not too anxious to catch it the evidence either, all belong to the magical discovery on one's own celestial body as the E.T. and haunt after all, not very good like this, it is not Mr. Ni Kuang that is writing the novel.
