TEXT
CLONING
It used to be only in science fiction that the , existence of a race of identical creatures could be imagined: a group of people with exactly the same hair colour, the same features and the same height. However, now this dream - or nightmare - could actually become reality. In theory, the process of creating replicas of any living being seems quite simple. First, a body cell, which contains the specific genes of a living organism, splits in two. The resulting new cells, each containing the same genes, then grow into two new, identical organisms. This process is known as cloning, and it can be applied to humans, animals, insects and plants.
Early experiments with cloning took place using the tadpoles of frogs. In 1968, Dr J.B. Gurdon of Oxford University, England, took an unfertilised frog's egg from a frog - let us call it frog number 1 - and destroyed its nucleus. This meant that he had removed all the genetic information which related to this frog. He then inserted a new nucleus extracted from a cell from another frog number 2. The tadpole which developed from the egg produced by frog number 1 was identical to frog number 2, not to frog number 1! It was not until 1996, however, in Scotland, that a group of British researchers led by Ian Wilmut achieved the successful cloning of an adult animal. The result was Dolly, who has taken her place in the history books as the first lamb to be cloned from the DNA of an adult sheep.
Following the birth of Dolly, both scientists and ordinary people have begun to think about the possibilities of cloning. The latest technology now means that we can remove body cells from the best of our race, the brilliant scientist, the musical genius, the child prodigy, and ensure that the same genes are reproduced in as many babies as we wish. However, cloning does not mean copying.
The process actually takes its name from the Greek word cion which means a twig. A twig has the same genetic information as the tree it comes from, but the two look very different. In the same way, a clone shares the same genes as its donor, but its behaviour and characteristics will be different: personality will always be unique.
Science has provided us with knowledge which seems to have unlimited possibilities. We can not only make designer human beings, but we can also use cloning to improve health. For example, scientists predict that in the future, pigs with organs that could be used in human transplants, could be cloned. Cloning could also enable us to learn more about the embryo and how organisms develop. Cloning could put an end to the risk of extinction of the endangered species on our planet; if animals can be cloned, they need never die out.
However, the process is very controversial. Some people have asked whether a cloned individual would really be a human; would it have a soul? Would there.be relationships and responsibilities between donors and clones? What would be the position of the children of donors in relation to clones? These people are concerned that cloning, or genetic engineering, would interfere with the laws of religion or nature. Others are concerned that it might lead to attempts to alter the features of a particular race and result in a new kind of ethnic cleansing. The fact is that the new opportunities offered by science have always meant that we are faced with new ethical questions. These questions need to be discussed and evaluated before we move ahead.

TEXT
VLADIMIR IVANOVICH VERNADSKY
(1863 - 1945)
Throughout the entire history of mankind there have been few thinkers who could equal the Russian scientist Vladimir Ivanovich Vernadsky. He was an outstanding mineralogist, geochemist, crystallographer, theoretical geologist and the lounder of many scientific establishments. He managed to see Earth from outer space fifty years before the first space flight. He saw it not only as one of the bodies in the solar system, but distinguished continents and oceans, rocks and living things, humans, minerals, atoms and molecules; he saw that "humans for the first time are becoming a geological force, capable of changing the face of our planet."
V.I. Vernadsky was born on March 12, 1863 in the family of a political economy professor. He spent his early childhood in Kharkov. He entered grammar school in 1873. In 1876 the family moved to Petersburg. The teaching faculty of Petersburg University at that time included D.I. Mendeleyev, V.V. Dokuchayev, and others. These prominent scientists were to play a particularly important role in Vernadsky's becoming an outstanding scientist. The thirst for knowledge, the joy of being free of the musty grammar school pushed Vernadsky to lectures not only in the natural sciences branch of the physical-mathematical department but in other departments as well.
In 1885 V.I. Vernadsky graduated from the university and was given a job as a custodian of the mineralogical department. His independent work began. Many of Vernadsky's achievements have not become outdated with the passage of time; indeed they have become more relevant. I am referring to his work on the biosphere and men's global and space activity. Vernadsky spoke of turning the biosphere into a new entity, an area on the planet where human will, reason, and labour would prove themselves in a radical way (making a noosphere — a sphere of reason).
According to Vernadsky, human knowledge is not only a personal and social phenomenon but also a kind of a planetary phenomenon adjoined to the field of life. "Being part of the biosphere, man can judge the world order only by comparing the phenomenon which he can see in it." Our current concept of the biosphere is based mainly on Vernadsky's theories.
After 1917 Vernadsky's scientific activity broadened. He took up new, highly difficult problems, put forward new ideas, wrote new books and articles on the history of minerals, on natural waters, on the circulation of the Earth's substances and gases, on space dust, geometry, the problem of time in modern science and on geochemical activity of living matter. In 1927 he organized a biogeochemical laboratory. In 1937 he addressed the international geological congress on "the significance of radioactivity for modern geology."
Till the very last days of his life Vernadsky remained on the frontiers of science: he pondered on the basics of the new teaching of the noosphere, directed the work of the committee on meteorites, researched isotope applications and worked a lot on the uranium problem. Owing to him, this country started to take measures to create an atomic industry and the raw materials basis for it. He attributed great significance to the use of nuclear energy for peaceful and creative purposes, for the creation of the noosphere.
At the age of almost 82 the scientist continued to work. The difficult war years, the newspaper reports about nazi atrocities seriously affected his health. He died on January 6, 1945. He was an inspired truth-seeker. "There is nothing stronger than the thirst for knowledge, the force of doubt...", he claimed. "We know just a small part of nature, just a tiny particle of that puzzling, murky and all-enveloping enigma, and everything that we know we have learned thanks to the dreams of the dreamers, fantasy-seekers and learned poets.
