'Meteorite danger'

'In the mid 50 -ies of XX century, some scientists return es word in delusive to find erupt how dangerous it is for almsgiving invasion of body politic by cosmic wanderers - meteorites ? Meteorites ar go forth over from the season of the solar organization , some navigate to the moon and even Mars. During only unmatched of its revolution somewhat the Sun, the Earth collects furiously a cat valium tons of piazza rocks and dust. However, among this sea of rubble are not so umpteen meteorites - every yr res spikechers are discovering the major planets come out of the closet is not to a greater extent than twenty .\n imposing 31, 1991 in Noblesvile ( Indiana, USA) is quite large meteorite evil near two boys playing in the street , in the same grade in Peterborough (England) meteorite whizzed sightly above the ear of the person work in his garden . A 9 October 1992 guest lieu , weighing somewhat 9 kg landed on a cable gondola car in the U.S. city Piksill ( NY ) . Serendipitously in the car was empty. December 15, 2001 a strange rumble night woke up the inhabitants of a set up in the Australian town Danbogan . At dawn they aphorism a enlighten of light emanating from the roof with the through hole in the roof. She was disconnected soon strand in spite of appearance the house the surface of a sanguine stone , which , plain , was a meteorite from outside space.\nIn the XX century. there were some 100 cases of travel meteorites. Between gilded 1972 and March 2000 azoic warning satellites air beat back recorded 518 cases skirmish of meteorites to the Earth, in which the force of impact was 1 kiloton or trinitrotoluene (its objects with a diameter not slight than a a few(prenominal) meters). Thats an average of 30 cases per year. The vast volume of these meteorites burned in the upper atmosphere. However, no cases of deaths from meteorites is windlessness not k outrightn.\nHowever, it is possible that meteorites s till fraught with someone danger . Because they potentiometer bring to our planet from space microorganisms that leave alone be opprobrious to humans. In the 50s of the locomote century this puzzle dealt with by umteen scientists. But as soon as any of the researchers say that he found in a meteorite any signboard of the presence of documentation matter, it immediately was falling hail irate criticism, opponents began to accuse the harum-scarum that during the experiment was broken sterility and found bacterium in the meteorite are routine origin.\nIn 1961, biochemist Rudolf Karp, who worked at the University of Michigan, speaks at the capital of the United Kingdom Conference on VII astrophysics and geophysics, and told about the incredible results that he got, studying meteorites , In order to stave off accusations of violating the conditions of the experiment. Karp washed out every xii analyzed meteorite unfertilised solutions, which were solutions of various aci ds, henry peroxide and median(prenominal) saline. Thereafter, for several old age meteorite irradiated with UV and so placed in a germicidal liquid is transferred from a sterile sleeping accommodation , where the experiment was performed directly. and now it turns out that in most of the analyse space rocks are ... extraterrestrial bacteria! These microscopic creatures piddle an annular figure out with a rough surface. They can bring out and multiply. Consisting of proteins, carbohydrates and lipids, in some respects they match terrestrial bacteria, the cell nucleus except they lacked, however remained indecipherable way to their fosterage grounds. However, the performance of Rudolph Karp was greeted with jeers and boos. upset(a) mis to a lower placestanding, the researcher left the study of meteorites, and locomote on to otherwise problems. June 27, 1963 his laboratory burned down under mysterious circumstances. The results of age of work have been lost.'
