Gentic Engineering

Perfectly round tomatoes all exactly the same size, long straight cucumbers and big fat chickens are now a normal part of our diets. They are made that way by genetic engineering – not by nature. Their genes have been changed. Every living thing has genes. They are passed on from generation to generation. They make sure that humans give birth humans and cows give birth to cows. They also make sure that a dog cannot give birth to a frog or an elephant to a horse. Genetic engineers take genes from one species and transfer them to another. In this way a new life form is created. Genetic engineers put duck genes into chickens to make the chickens bigger. They put hormones into cows to make them produce more milk. They put genes from flowers into soya beans and from scorpions into corn. This does not make them cheaper, tastier or healthier. It makes them easier and faster for the farmer to grow. The effects of genetic engineering on our health are not know. Many of the genes which are used are not part of uor diet so we do not know how dangerous they might be. The effects of genetic engineering on the natural world may be disastrous. The engineers may create life forms that we cannot control. The effects of these experiments can often be cruel. In America pigs were given human genes to make them bigger and less fatty. The pigs became very ill and began to lose their eyesight.

Have Canadians discovered gene, which blocks HIV?

Canadian scientists have discovered gene, which may stop expanding of HIV virus and AIDS evolution. Specialists say that it is the ravine in studies on vaccine and cure for this incurable so far disease.
Gene named TRIM22 shows natural defensive function. It’s the only human gene which has the ability to block HIV virus. Scientists from Alberty University hopes, that this discover will help in developing vaccine for this deadly virus. “It’s really exciting – the human organ can defend himself against the HIV virus” –said chief of studying crew Steven Barr.
TRIM22 gene, activated in bacterial culture attacked by HIV virus, blocks its breeding and holds it in cell. Canadian scientist discovered, that in infected person this gene is inactive.
Steven Bar says that further studies may last for even ten years, before the first curing methods can be discovered. Specialists points though, that this discovery is really significant step into discovering the cure for AIDS.

The beginnig of science

The beginning of man's interest of surrounded him world is dated on prehistorical time. People who lived on that times were making plates of bone on which were painting symbols Moon phase. That plate was found in France and it is dated on 32 thousand yeras old. They then made a construction subordinated astronomy Stonehenge in England. Times to Middle Ages are recognized of prescientific epoch. People tried control nature strength with magic.
The important moment in history of knowledge was invention of writing. It made possible consolidation and storing knowledge. People started make lists of towns, kind of plants, animals, mountains or rivers. In Mezopotamia was invented record of any number with help of limited quantity of digits. People could count areas of figures or measure angles.
In ancient Egypt progressed astronomy and mathematician. People could make four basic operations - operations on fractions, simple problems related with geometry. I'm wondering weren't they smarter than me. Egyptians could measure time. Theh made solar watch and probably water watch. Progressed geographic knowledge of which sign is Egyptian map of Nubia. In Egypt was also medicine on high.
Generally science had a small influance on society, because people didn't write down any theory, statement or formula. People rather wrote important on that times things. More exactly Priests took care science. Sometimes was that also rulers, but as marginal occupation.

Can life exist on Mars?

Mars has already from centuries interested people of all cultures because of its colour - red and seemingaly fast movement on the sky.
Scientists say, Mars is too salt to life could exist there. From a analysis of Red Planet's rock fragments, which was washed by water it ensues, that Mars was unusual rich of minerals.
The scientists think that stage of salinity would make impossible rise of life. In their opinion even the most immune bacteriums couldn't survive in that medium. For few latest months stones from Martian plain was exactly explore by American scientists from NASA. From those explorations it ensues, that before few thousands years there was water. Results of today explorations say about that, there couldn't be life even if there was that necessary thing to live - water.

Super-mouse

She can run for hours - in minute she overcomes 20 monute without crucifying. She lives longer, eat as much as she want and don't become fat. Scientists created super-mouse. Can we create super-human?

Scientists created transgenic super-mouse with super physic skills - it only can be compare  with results of the best  sportsman. Scientists believe that someday human physic skills can become better too.

She can run 6 kilometers with speed 20 meters per minute(without stopping for 5 hours). She lives three cases more. An american scientists have now colony with 500 mice. They 'did' super-mouse by changed one gene of metabolism with gene form human. In physical fetch mouse use fatty acids cause it have full energy value.
